Citation Nr: 1328381 Decision Date: 09/05/13 Archive Date: 09/16/13 DOCKET NO. 07-16 991 ) DATE ) ) On appeal from the Department of Veterans Affairs Regional Office in Nashville, Tennessee THE ISSUES 1. Entitlement to service connection for a left knee disorder. 2. Entitlement to service connection for a psychiatric disorder, to include posttraumatic stress disorder (PTSD). REPRESENTATION Veteran represented by: J. Michael Woods, Attorney at Law WITNESSES AT HEARING ON APPEAL The Veteran and his spouse ATTORNEY FOR THE BOARD J.A. Flynn, Associate Counsel INTRODUCTION The Veteran served on active duty in the United States Army from September 1970 to April 1972. The Veteran had additional periods of active duty for training (ACDUTRA) service, including, in pertinent part, in August 1985. This matter comes to the Board of Veterans' Appeals (Board) on appeal from April 2006 and March 2008 rating decisions of the Department of Veterans Affairs (VA) Regional Office (RO) in Nashville, Tennessee. These matters have previously been before the Board, most recently in December 2012, when the Board remanded the claims for additional development of the evidence of record. As an initial matter, the Board notes that when its remand orders are not complied with, it errs as a matter of law when it fails to ensure compliance. See Stegall v. West, 11 Vet. App. 268, 271 (1998). As will be discussed in further detail below, the Board finds that there has been effective compliance with the Board's remand instructions. See Dyment v. West, 13 Vet. App. 141, 146-47 (1999) (noting that Stegall requires substantial compliance with remand orders, rather than absolute compliance.) Since the time of the most recent statement of the case, the Veteran has sent correspondence directly to the Board without a waiver of review in the first instance by the agency of original jurisdiction. On review, this communication is duplicative of information already contained in the claims file and is irrelevant to the issues on appeal to the Board. Accordingly, a remand to the RO for initial review of the newly-received documents is not required. See Sabonis v. Brown, 6 Vet. App. 426, 430 (1994) (remands that would only result in imposing additional burdens on VA, with no benefit flowing to the claimant, are to be avoided.) Although a Veteran may only claim service connection for a particular psychiatric disorder, the claim cannot be a claim limited only to that diagnosis, but must rather be considered a claim for any mental disability that may be reasonably encompassed. Clemons v. Shinseki, 23 Vet. App. 1 (2009). The Board will consider entitlement to service connection for all psychiatric diagnoses raised by the record. FINDINGS OF FACT 1. The competent and credible evidence of record does not support a finding that a relationship exists between the Veteran's left knee disorder and his military service. 2. The competent and credible evidence of record does not support a finding that a relationship exists between the Veteran's acquired psychiatric disability and his military service. CONCLUSIONS OF LAW 1. A left knee disorder was not incurred or aggravated by the Veteran's active duty military service, and arthritis may not be presumed to have been. 38 U.S.C.A. §§ 1110, 1131, 5103, 5103A, 5107 (West 2002 & Supp. 2012); 38 C.F.R. §§ 3.012, 3.159, 3.303, 3.307, 3.309 (2012). 2. An acquired psychiatric disability, to include PTSD, was not incurred or aggravated by the Veteran's active duty military service, and a psychosis may not be presumed to have been incurred therein. 38 U.S.C.A. §§ 1110, 1131, 5103, 5103A, 5107 (West 2002 & Supp. 2012); 38 C.F.R. §§ 3.159, 3.102, 3.303, 3.307, 3.309 (2012). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS The Board has thoroughly reviewed all the evidence in the Veteran's claims file. While the Board has an obligation to provide reasons and bases supporting this decision, there is no need to discuss, in detail, the evidence submitted by the Veteran or on his behalf. See Gonzales v. West, 218 F.3d 1378, 1380-81 (Fed. Cir. 2000) (the Board must review the entire record, but does not have to discuss each piece of evidence). The analysis below focuses on the most salient and relevant evidence and on what this evidence shows, or fails to show, on the claim. The Veteran must not assume that the Board has overlooked pieces of evidence that are not explicitly discussed herein. See Timberlake v. Gober, 14 Vet. App. 122 (2000) (the law requires only that the Board address its reasons for rejecting evidence favorable to the Veteran). The Board must assess the credibility and weight of all evidence, including the medical evidence, to determine its probative value, accounting for evidence which it finds to be persuasive or unpersuasive, and providing reasons for rejecting any evidence favorable to the Veteran. Equal weight is not accorded to each piece of evidence contained in the record; every item of evidence does not have the same probative value. When all the evidence is assembled, the Board is responsible for determining whether the evidence supports the claim or is in relative equipoise, with the Veteran prevailing in either event, or whether a preponderance of the evidence is against a claim, in which case, the claim is denied. See Gilbert v. Derwinski, 1 Vet. App. 49 (1990). The Veterans Claims Assistance Act of 2000 (VCAA) The Board has given consideration to the VCAA, which includes an enhanced duty on the part of VA to notify a veteran of the information and evidence necessary to substantiate claims for VA benefits. See 38 U.S.C.A. §§ 5103, 5103A (West 2002 & Supp. 2012); 38 C.F.R. § 3.159 (2012). The VCAA also defines the obligations of VA with respect to its statutory duty to assist veterans in the development of their claims. See 38 U.S.C.A. §§ 5103, 5103A (West 2002 & Supp. 2012). Upon receipt of a complete or substantially complete application for benefits, VA is required to notify the claimant and his representative, if any, of any information, and any medical or lay evidence, that is necessary to substantiate the claim. See 38 U.S.C.A. § 5103(a) (West 2002); 38 C.F.R. § 3.159(b) (2011); Quartuccio v. Principi, 16 Vet. App. 183 (2002). Proper notice from VA must inform the claimant of any information and evidence not of record (1) that is necessary to substantiate the claim; (2) that VA will seek to provide; and (3) that the claimant is expected to provide. This notice must be provided prior to an initial unfavorable decision on a claim by the agency of original jurisdiction. See Mayfield v. Nicholson, 444 F.3d 1328 (Fed. Cir. 2006); Pelegrini v. Principi, 18 Vet. App. 112 (2004). In addition, the notice requirements of the VCAA apply to all five elements of a service-connection claim, including: (1) veteran status; (2) existence of a disability; (3) a connection between the veteran's service and the disability; (4) degree of disability; and (5) effective date of the disability. See Dingess v. Nicholson, 19 Vet. App. 473 (2006). Further, this notice must include information that a disability rating and an effective date for the award of benefits will be assigned if service connection is awarded. See id. at 486. Determinations concerning prejudicial error and harmless error should be made on a case-by-case basis. See Shinseki v. Sanders, 129 S.Ct. 1696 (2009). In the instant case, with respect to the Veteran's claim for service connection for a left knee condition, correspondence dated September 2005 and February 2006 notified the Veteran of information and evidence necessary to substantiate the claim; information and evidence that VA would seek to provide; and information and evidence that the Veteran was expected to provide. The Veteran filed his claim prior to the Court's 2006 decision in Dingess, and as such, he was not provided with full Dingess notice at the time of the original VCAA notice letters. Instead, in May 2006, pursuant to the Court's holding in Dingess, the Veteran was provided with notice regarding the degree of disability and effective date. Additionally, since the time of the May 2006 Dingess notice, the Veteran has been provided with several readjudications of his claim, and the Board finds that there has been no prejudice to the Veteran requiring additional notice. With respect to the Veteran's claim for service connection for an acquired psychiatric condition, a June 2007 letter provided all necessary notice to the Veteran. The Board finds that the notice provisions of the VCAA have been fulfilled, and that no further notice is necessary. With respect to the duty to assist, VA has done everything reasonably possible to assist the Veteran with respect to his claims for benefits. 38 U.S.C.A. § 5103A (West 2002); 38 C.F.R. § 3.159(c) (2012). The Veteran's service treatment records, post-service private medical records, VA treatment records, and records from the Social Security Administration (SSA) have been obtained, to the extent available. The Veteran has been provided with VA examinations, including a supplemental psychiatric opinion in January 2013 and a supplemental orthopedic opinion in February 2013 pursuant to the Board's December 2012 Remand. Upon review of the examination reports of record, the Board observes that the examiners reviewed the Veteran's claims file and past medical history, recorded his current complaints and history, conducted appropriate evaluations, and rendered appropriate diagnoses and opinions consistent with the remainder of the evidence of record. The examination reports are therefore adequate for the purpose of rendering a decision in the instant appeal. See 38 C.F.R. § 4.2 (2012); see also Barr v. Nicholson, 21 Vet. App. 303, 312 (2007). The Veteran presented testimony before the undersigned at an August 2010 videoconference hearing, and a transcript of this hearing is associated with the record. Thus, the duties to notify and assist have been met, and the Board will proceed to a decision. Service Connection for a Left Knee Disorder In general, service connection may be granted for disability or injury incurred in or aggravated by active military service. See 38 U.S.C.A. §§ 1110, 1131 (West 2002); 38 C.F.R. § 3.303 (2012). Active service includes any period of ACDUTRA during which the individual concerned was disabled or died from a disease or injury incurred or aggravated in line of duty. 38 C.F.R. § 3.6 (2012). In order to establish service connection for a claimed disorder, there must be (1) medical evidence of a current disability; (2) medical, or in certain circumstances, lay evidence of in-service incurrence or aggravation of a disease or injury; and (3) evidence, generally medical, of a nexus between the claimed in-service disease or injury and the current disability. See Hickson v. West, 12 Vet. App. 247, 253 (1999). Service connection may also be granted for any disease initially diagnosed after service, when the evidence establishes that the disease was incurred in service. See 38 U.S.C.A. § 1113(b) (West 2002); 38 C.F.R. § 3.303(d) (2012); Cosman v. Principi, 3 Vet. App. 503, 505 (1992). The disease entity for which service connection is sought must be chronic rather than acute and transitory in nature. For the showing of chronic disease in service, a combination of manifestations must exist sufficient to identify the disease entity and sufficient observation to establish chronicity at the time, as distinguished from merely isolated findings or a diagnosis including the word "chronic." For certain chronic diseases set forth in 38 C.F.R. § 3.309(a), a continuity of symptomatology is required when the condition noted during service is not shown to be chronic or where the diagnosis of chronicity may be legitimately questioned. See 38 C.F.R. § 3.303(b) (2012); Walker v. Shinseki, 708 F.3d 1331 (Fed. Cir. 2013) (noting that a "continuity of symptomatology" as specified in 38 C.F.R. § 3.303(b) affords an alternative route to service connection only for specific chronic diseases). To the extent that the Veteran's claimed left knee disorder represents a degenerative or arthritic process, arthritis is among the chronic diseases set forth in 38 C.F.R. § 3.309, and it therefore may be established based on a continuity of symptomatology. See Walker. With regard to the first Hickson element, medical evidence of a current disability, the March 2009 VA examination, among other medical evidence, demonstrates that the Veteran suffers from left knee arthritis. The first Hickson element, medical evidence of a current disability, is met. With respect to the second Hickson element, in-service disease or injury, an August 1985 informal line of duty determination indicated that the Veteran was treated for left knee bruises following a truck accident. The second Hickson element is therefore met as to an in-service injury. Regarding the third Hickson element, medical evidence of nexus, the determination of the relationship, if any, between the Veteran's current disability and his military service, is essentially medical in nature. The Board is prohibited from exercising its own independent judgment to resolve medical questions. See Colvin v. Derwinski, 1 Vet. App. 171, 175 (1991). In April 2007, E.K., a private primary care nurse, stated that the Veteran began complaining of increased left knee pain in September 2006. E.K. indicated that the Veteran reported a prior injury in 1985 while on active duty with the military. In June 2007 and July 2007, D.L., a private chiropractor, stated that the Veteran suffered a "severe injury to his knee" in 1985. D.L. reported that since the Veteran's injuries, the Veteran's medical conditions have increased in severity. Also in June 2007, the Veteran submitted a statement illegibly signed by a "Doctor of Chiropractic" that the Veteran had "left knee damage back to military service 1971- 1975." In January 2009, the Veteran submitted an illegibly signed statement indicating that the Veteran suffered from a left knee disorder that started after a truck accident that occurred while in the military. The Veteran underwent a VA examination in March 2009, at which time the examiner diagnosed left knee arthritis and opined that the arthritis was not due to the trauma associated with the 1985 accident. One of the reasons that the examiner provided to support the conclusion was that the injury was not particularly severe, relying in part on a finding that the Veteran did not seek medical attention for the injury until one week after the injury occurred. The Board noted in its December 2012 Remand that this finding was inaccurate. Service treatment records include a DA Form 2173 statement of medical examination and duty status, which indicates that the accident occurred on August 5, 1985, the Veteran was admitted as an outpatient at an emergency room on August 5, 1985, examined at that time, and was found to have left knee bruises incurred in a truck accident. Thus, the examiner's statement that the Veteran did not seek treatment until one week after the accident is not accurate. As this was one of the reasons for the determination that his current left knee arthritis is not related to that event, the examination is inadequate. See Reonal v. Brown, 5 Vet. App. 457, 461 (1993) (an opinion based on an inaccurate factual premise is not probative). Therefore, the Board found that Remand was necessary so that the claims file could be returned to the examiner, or to another similarly qualified examiner, so that an opinion could be provided taking into consideration that the treatment for his left knee occurred on the same date that the accident occurred. See Barr v. Nicholson, 21 Vet. App. 303, 311 (2007) (explaining that once VA undertakes the effort to provide an examination it must provide an adequate one). Accordingly, the March 2009 examiner provided an addendum opinion in February 2013. The examiner found that the Veteran's claimed left knee condition was less likely than not incurred in or caused by the claimed in-service injury, event, or illness. The examiner noted that the Veteran's service treatment records indicate that the Veteran's 1985 injury was a soft-tissue injury that would be expected to last for only a temporary period of time. This sort of soft-tissue injury would not cause the degenerative arthritis that is seen in the Veteran's left knee. The Veteran's left knee condition is due to degenerative bony abnormality; the Veteran's original injury was to a different tissue system entirely, that is, the soft tissue, not the bone. The examiner noted that service treatment records indicated that the contusion was of a minor nature. The physical description of the wound stated that there was no residual tenderness and no ecchymosis. The record also indicated that the Veteran was returned to full duty and was not limited in his activities. The examiner noted that this too demonstrated the mild nature of the Veteran's original injury. The examiner further noted that both the Veteran's left and right knees demonstrate degenerative changes, which further indicates that the Veteran's degenerative changes in his left knee are unrelated to his in-service knee injury. Upon review of the evidence, the Board observes three medical opinions that arguably support a finding that the Veteran's left knee disorder is related to active duty service: the April 2007 statement from E.K., the June 2007 statement from D.L., and the January 2009 statement that is illegibly signed. The Board, however, affords each of these opinions with relatively little probative weight. None of these opinions was accompanied by a discussion of the pertinent evidence of record, including the lengthy period of time between the Veteran's period of ACDUTRA service in 1985 and his first treatment for left knee pain in 2006. None of these opinions were accompanied by a rationale explaining why the Veteran's current condition was likely related to his in-service military accident. Furthermore, the Board observes that the description of the severity of the 1985 incident is based solely on the Veteran's self- reported history. A mere transcription of lay history, unenhanced by any additional medical comment by the transcriber, does not become competent medical evidence merely because the transcriber is a medical professional. See LeShore v. Brown, 8 Vet. App. 406, 409 (1995); see also Reonal v. Brown, 5 Vet. App. 458, 461 (1993); Elkins v. Brown, 5 Vet. App. 474, 478 (1993). To the extent that the Veteran believes that his left knee disorder is related to his military service, the Board notes that the Veteran is competent to provide testimony concerning factual matters of which he has first-hand knowledge (that is, experiencing physical symptoms such as pain). See Barr v. Nicholson, 21 Vet. App. 303 (2007); Washington v. Nicholson, 19 Vet. App. 362 (2005). Further, under certain circumstances, lay statements may support a claim for service connection by supporting the occurrence of lay-observable events or the presence of disability, or symptoms of disability, susceptible of lay observation. See Davidson v. Shinseki, 581 F.3d 1313 (Fed. Cir. 2009); Jandreau v. Nicholson, 492 F.3d 1372 (Fed. Cir. 2007). Indeed, VA provided the Veteran with examinations based on the competency of these observations. Although lay persons are competent to provide opinions on some medical issues, see Kahana v. Shinseki, 24 Vet. App. 428, 435 (2011), as to the specific issue in this case, namely, the etiology of a left knee condition, the issue of causation of such a medical condition is a medical determination outside the realm of common knowledge of a lay person. See Jandreau v. Nicholson, 492 F.3d 1372, 1377 n.4 (Fed. Cir. 2007) (lay persons not competent to diagnose cancer). Thus, although the Board has carefully considered the lay contentions of record suggesting that the Veteran's left knee disorder is related to his military service, the Board ultimately affords the objective medical evidence of record, which fails to find a connection between the Veteran's condition and his military service, with greater probative weight than these lay opinions. Pursuant to 38 C.F.R. § 3.309, the Board has also considered whether the Veteran has presented a continuity of symptomatology associated with his left knee symptoms, and it finds that he has not done so. There is no competent medical evidence indicating that the Veteran was treated for left knee pain until September 2006, or approximately 21 years after the 1985 in-service incident. See Maxson v. Gober, 230 F.3d 1330, 1333 (Fed. Cir. 2000) (noting that it was proper to consider the veteran's entire medical history, including the lengthy period of absence of complaint with respect to the condition he now raised). Thus, while the Board has considered the lay contentions that the Veteran experienced left knee problems after military service, the Board finds that the weight of the evidence does not support a finding of continuous symptoms since active duty. Thus, the medical nexus element of Hickson cannot be met via continuity of symptomatology with regard to the Veteran's claimed low back disorder. The Board acknowledges that VA is statutorily required to resolve the benefit of the doubt in favor of the veteran when there is an approximate balance of positive and negative evidence regarding the merits of an outstanding issue. That doctrine, however, is not applicable in this case because the preponderance of the evidence is against the claim. See 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). The preponderance of the competent and probative evidence of record indicates that the Veteran's left knee disorder is not related to his military service. Accordingly, the third Hickson element, competent evidence of nexus, has not been satisfied. The benefit sought on appeal is accordingly denied. Service Connection for an Acquired Psychiatric Disorder The Veteran argues that he has an acquired psychiatric disorder, to include PTSD, that is the direct result of either his in-service experiences, or, alternatively, is secondary to his left knee arthritis. Service connection may be established on a secondary basis for a disability that is proximately due to or the result of a service-connected disease or injury. 38 C.F.R. § 3.310(a) (2012); Harder v. Brown, 5 Vet. App. 183, 187 (1993). Additional disability resulting from the aggravation of a non-service-connected disability by a service-connected disability is also service connected. 38 C.F.R. § 3.310 (2012); Allen v. Brown, 7 Vet. App. 439 (1995). To establish service connection for a claimed disability on a secondary basis, there must be medical evidence of a current disability, a service-connected disability, and medical evidence of a nexus between the service-connected disability and the current disability. Wallin v. West, 11 Vet. App. 509 (1998). This decision has denied the Veteran's claim for service connection for a left knee disability. Therefore, the Veteran's claim for service connection for an acquired psychiatric disability on a secondary basis fails on the basis that the Veteran's left knee condition is not service-connected. As noted above, in order to establish service connection for a claimed disorder on a direct basis, there must be (1) medical evidence of a current disability; (2) medical, or in certain circumstances, lay evidence of in-service incurrence or aggravation of a disease or injury; and (3) evidence, generally medical, of a nexus between the claimed in-service disease or injury and the current disability. See Hickson v. West, 12 Vet. App. 247, 253 (1999). More specifically, service connection for PTSD requires: (1) medical evidence diagnosing the condition in accordance with VA regulations; (2) credible supporting evidence that the claimed in-service stressor occurred, and (3) a link, established by medical evidence, between current symptoms and an in-service stressor. 38 C.F.R. § 3.304(f) (2012). Service connection may also be granted for any disease initially diagnosed after service, when the evidence establishes that the disease was incurred in service. See 38 U.S.C.A. § 1113(b) (West 2002); 38 C.F.R. § 3.303(d) (2012); Cosman v. Principi, 3 Vet. App. 503, 505 (1992). The disease entity for which service connection is sought must be chronic rather than acute and transitory in nature. For the showing of chronic disease in service, a combination of manifestations must exist sufficient to identify the disease entity and sufficient observation to establish chronicity at the time, as distinguished from merely isolated findings or a diagnosis including the word "chronic." For certain chronic diseases set forth in 38 C.F.R. § 3.309(a), a continuity of symptomatology is required when the condition noted during service is not shown to be chronic or where the diagnosis of chronicity may be legitimately questioned. See 38 C.F.R. § 3.303(b) (2012); Walker v. Shinseki, 708 F.3d 1331 (Fed. Cir. 2013) (noting that a "continuity of symptomatology" as specified in 38 C.F.R. § 3.303(b) affords an alternative route to service connection only for specific chronic diseases). To the extent that the Veteran's claimed acquired psychiatric condition represents a psychosis, this condition is among the chronic diseases set forth in 38 C.F.R. § 3.309, and it therefore may be established based on a continuity of symptomatology. See Walker. The evidence required to establish a claimed in-service stressor depends on the nature of both the stressor and the Veteran's service. If the evidence establishes that the veteran engaged in combat with the enemy and the claimed stressor is related to that combat, the veteran's lay statements alone may establish occurrence of the claimed in- service stressor, in the absence of clear and convincing evidence to the contrary, as long as the claimed stressor is consistent with the circumstances, conditions, or hardships of the veteran's service. 38 U.S.C.A. § 1154(b) (West 2002); 38 C.F.R. § 3.304(f) (2012); Zarycki v. Brown, 6 Vet. App. 91 (1993). Even without combat participation, if the veteran's claimed stressor is related to "fear of hostile military or terrorist activity," and a VA psychiatrist or psychologist, or contract equivalent, confirms that the claimed stressor is adequate to support a diagnosis of PTSD, and the veteran's symptoms are related to the claimed stressor, in the absence of clear and convincing evidence to the contrary, and provided the claimed stressor is consistent with the places, types, and circumstances of the veteran's service, the veteran's lay testimony alone may establish the occurrence of the claimed in-service stressor. 38 C.F.R. § 3.304(f)(3) (2012). Fear of hostile military or terrorist activity means that a veteran experienced, witnessed, or was confronted with an event or circumstance that involved actual or threatened death or serious injury, or a threat to the physical integrity of the veteran or others, such as from an actual or potential improvised explosive device; vehicle-imbedded explosive device; incoming artillery, rocket, or mortar fire; grenade; small arms fire, including suspected sniper fire; or attack upon friendly military aircraft, and the veteran's response to the event or circumstance involved a psychological or psycho-physiological state of fear, helplessness, or horror. 38 C.F.R. § 3.304(f)(3) (2012). If the claimed stressor does not involve either combat or the fear of hostile military or terrorist activity, then the Veteran's claimed stressors must be corroborated by evidence other than the claimant's own testimony or the diagnosis of PTSD itself. 38 C.F.R. § 3.304(f) (2012); Dizoglio v. Brown, 9 Vet. App. 163, 166 (1996). The occurrence of an event alleged as the stressor upon which a PTSD diagnosis is based, as opposed to the sufficiency of the alleged event to cause PTSD, is an adjudicative determination, not a medical determination. Zarycki v. Brown, 6 Vet. App. 91 (1993). Turning to the facts in the instant case, any claim for service connection first requires the presence of a currently-diagnosed disability. VA treatment records indicate that the Veteran has been diagnosed with depressive disorder and PTSD. Therefore, the evidence shows a diagnosis of the claimed disability. The next element needed in order to establish a claim for service connection for PTSD or other acquired psychiatric disability is the presence of an in-service injury or disease (or, using terminology applicable to PTSD, a "stressor"). The Veteran's claim for PTSD is not based on either combat or his fear of hostile military activity. The Veteran's personnel and service medical records are negative for any indication that the Veteran participated in combat. The only listed decorations, medals, badges, commendations, citations, or campaign ribbon are the National Defense Service Medal and Sharpshooter (Rifle M-16) Badge, which do not imply that the Veteran was involved in combat. Instead, as will be discussed in further detail below, the Veteran claimed in-service stressors involve a 1971 head injury and a 1985 automobile accident. The liberalizing criteria relating to the fear of hostile military or terrorist activity that do not require a verified stressor, therefore, do not apply. See 38 C.F.R. §3.304(f)(3) (2012). Instead, the record must contain credible supporting evidence that the Veteran's claimed in-service stressors occurred. As will be discussed in further detail below, the weight of the evidence of record is against a finding that the claimed 1971 stressor occurred. While the weight of the evidence supports a finding that the 1985 stressor occurred, the evidence does not demonstrate a relationship between the Veteran's stressor and the Veteran's current symptoms. Analysis - 1971 Stressor The Board has reviewed the Veteran's service treatment records for any indication that the Veteran received treatment for a psychiatric disorder during active duty service, and it has found none. While the Veteran sought medical treatment in service on a number of occasions, the Veteran never sought treatment for mental health problems, and none of the Veteran's service treatment records refer even incidentally to mental health. Furthermore, the Veteran's service treatment records do not mention any incident involving a 1971 hatch lid incident or associated head trauma. The Veteran's January 1972 service separation examination was normal, and the Veteran stated at that time that he was in good health. Reports of medical examinations for re- enlistment in the Army Reserves from August 1976 and July 1980 show the same clinical results. In August 1976 and July 1980, the Veteran stated that he had never had a head injury or any other of the conditions listed on those forms. In the 1976 and 1980 forms, the Veteran indicated that he had been hospitalized when his appendix was removed. The Veteran stated that he did not have any illness or injury other than that which had been noted elsewhere in the forms. The Veteran's service treatment records indicate that he was hospitalized once: the Veteran underwent treatment in June 1979 for cellulitis of the legs. In August 2005, the Veteran stated to a private psychiatric practice that his problems "started about 3 months after [the Veteran] got hurt unloading a truck in Oregon." In an August 2005 psychological evaluation for SSA benefits, the Veteran recounted neither of his in-service stressor events. The psychologist diagnosed the Veteran with depression and alcohol abuse. In a September 2005 psychiatric review for SSA benefits, the Veteran was diagnosed with depression and substance addiction disorders. A December 2005 notation indicated that the Veteran was "trying to get VA benefits . . . injured in military in 70's." In August 2006, C.S., a private mental health nurse practitioner, indicated that she had treated the Veteran for medication management for generalized anxiety disorder and bipolar disorder since August 2005. In September 2006, D.B. indicated that the Veteran told him that a hatch from an armored personnel carrier (APC) fell on his head. Also in September 2006, W.D., a member of the Veteran's platoon in 1971-1972, indicated that the Veteran moved an APC, and the driver's hatch closed, striking the Veteran on the head. W.D. indicated that the Veteran had to be restrained by other soldiers and was ultimately evacuated by helicopter for medical attention. J.H. reported that he was serving in the Army in Germany in May 1971 at which time the Veteran was backing up a personnel carrier, the latch closed on the Veteran's head, he had to be restrained by 5 soldiers, went wild, and was evacuated by helicopter to a hospital. In December 2007, C.R., a private mental health nurse practitioner, indicated that the Veteran reported that in 1971, during field exercises in an APC, a hatch came loose, resulting in a head injury. The Veteran reported becoming confused, disoriented, and unconscious, and the Veteran was evacuated by helicopter for medical treatment. In a December 2007 statement, the Veteran indicated that during his period of service from 1971 to 1972, he was sitting in an APC when a hatch fell down on his head. The Veteran indicated that he then ran out of the APC into the woods. Several soldiers then grabbed him, and the Veteran stated that he blacked out for 30 seconds. The Veteran was evacuated by helicopter to the hospital, and his "life flashed in front of [him]." In February 2008, upon consideration of the above evidence, the RO issued a Formal Finding of a Lack of Information Required to Corroborate Stressors. The RO determined that the information required to corroborate the stressful events described by the Veteran was insufficient to send to the United States Army and Joint Services Records Research Center (JSRRC). In November 2007, the RO sent a letter to the Veteran requesting evidence for PTSD; the RO additionally requested PTSD records from the National Personnel Records Center (NPRC) at that time. In December 2007, the RO received PTSD records from the NPRC. Also in December 2007, the RO received the Veteran's stated stressors of being in an automobile accident and experiencing a hatch falling on his head. These stressors could not be sent to the JSRRC because they were non-combat. In January 2008, the RO sent a follow-up letter to the Veteran. In May 2008, the Veteran indicated that while serving in Germany in 1971 and 1972, the Veteran was ordered to back up his APC, when a heavy steel latch came down directly on his head. The Veteran ran away, someone ran after him and stopped him, and the Veteran's head swelled immediately. The Veteran ran away again until he was stopped. The Veteran then lost consciousness and was evacuated by helicopter. The Veteran awoke the next day in the hospital. In June 2008, the Veteran indicated that he experienced head trauma from having a heavy steel latch come down directly on his head. The Veteran reported that he had altered mental status at the scene, and he was told that he struck an officer. The Veteran was taken by helicopter to the hospital. The Veteran had a subsequent loss of memory, and he was told that his head and brain swelled. In November 2008, the Veteran stated that his military occupational specialty in 1971 was classified. The Veteran indicated that he was ordered to back up an APC and he did not have a helmet on, and a hatch came loose and hit the Veteran on the head. The Veteran indicated that he ran outside into the woods, and it took four or five other soldiers to "take [him] down." The Veteran then lost consciousness. A helicopter was standing by, and the Veteran then woke up in a military hospital. The Veteran then underwent a "major operation" on his head. In December 2008 neuropsychological testing, an examiner found that the results of the Veteran's testing were invalid due to the Veteran's exaggeration of symptoms. The Veteran underwent a VA examination in April 2009. The Veteran stated that he saw "dead bodies" in Germany in association with an accident involving an APC. The Veteran indicated that he was afraid "because they were ordered to back it up." The Veteran reported that he experienced head trauma around February 1972 from having a heavy steel latch drop down directly on his head. In August 2009, the Veteran's sister indicated that the Veteran wrote her a letter while he was stationed in Germany, stating that he had been hospitalized for head trauma and that he had witnessed other soldiers being killed. In October 2009, the Veteran's daughter stated that "five of [the Veteran's] soldiers got killed in front of him." Also in October 2009, M.D.K., a relative of the Veteran's stated that he saw men killed while serving in Germany. She further stated that a lid hit him in the head, and his team had to hold him down. In October 2009, J.R. stated that the Veteran told him that he witnessed soldiers being killed. The Veteran further related that he was hit on the head with a hatch. In an October 2009 statement in support of the Veteran's claim for service connection for PTSD, the Veteran stated that he was sitting in the driver's seat of an APC when another APC passed him. The other APC turned over, killing all of the soldiers on board. The Veteran was told to move his APC back 20 feet, when his APC hatch came loose and hit him on the head. The Veteran ran away from the APC, and it took five soldiers to hold him down. The Veteran's head swelled, and he was taken to a hospital. The Veteran did not remember the helicopter evacuation. Later in October 2009, the Veteran stated that he almost died in service after being knocked unconscious. The Veteran indicated that he woke up in a hospital with an IV-drip, and he knew that his head was swollen. In October 2009, the Veteran's brother stated that the Veteran told him that he was hospitalized following a head trauma in service. The Veteran also stated that he witnessed the death of some of his fellow soldiers. In an April 2010 VA examination, the Veteran alleged that a hatch hit him on the head in 1971, and he was later evacuated by hospital. The examiner noted that in the Veteran's 1972 service separation examination, the Veteran denied having a history of head injury. The examiner did not find enough evidence to support the claim that a trauma occurred, and the examiner thus found that the Veteran did not qualify for a diagnosis of PTSD. In May 2010, the RO again issued a Formal Finding of a Lack of Information Required to Corroborate Stressors Associated with a Claim for Service Connection for PTSD. The RO determined that the information required to corroborate the stressful events described by the Veteran was insufficient to send to the JSRRC. In a July 2010 treatment record, a VA clinician diagnosed the Veteran with PTSD, noting that in 1971 or 1972, the Veteran saw an APC turn over and witnessed the deaths of 5 crew members when he had to back up his APC. The Veteran further reported experiencing a head injury when the hatch of his APC closed. The examiner indicated that the Veteran met the criteria for PTSD in terms of the stressors involved and the symptoms present. In his August 2010 hearing before the undersigned, the Veteran indicated that in 1971, an APC flipped over and killed and injured some soldiers near him. The Veteran was on-guard at APC lookout during this time, and he witnessed this event through binoculars. The Veteran indicated that his APC hatch hit him on the head, and he was knocked out for 10 seconds. The Veteran indicated that he had flashbacks of witnessing the deaths of other soldiers. The Veteran did not know which hospital treated him, but he was in a special unit devoted only to head injury. Turning to an evaluation of the competency, credibility, and weight to be afforded to this evidence, the Board acknowledges that the Veteran is competent to give evidence regarding what he experienced in-service, such as recounting events that he witnessed or feelings that he experienced. See Jandreau v. Nicholson, 492 F.3d 1372 (Fed. Cir. 2007); Buchanan v. Nicholson, 451 F.3d 1331, 1337 (Fed. Cir. 2006); Layno v. Brown, 6 Vet. App. 465 (1994). While the Veteran is competent to provide such evidence, the Veteran's stressors must be corroborated by evidence other than his own testimony. The Board finds that the Veteran has not provided credible corroboration of this claimed incident. The Board, as the fact finder, must determine the credibility of lay evidence. See Culver v. Derwinski, 3 Vet. App. 292, 297 (1992). The Board finds that the Veteran's description of his 1971 in-service stressor lacks credibility because it has been inconsistent over time. In September 2006, the Veteran's own statements and lay statements from others indicated that he experienced only a head injury in 1971. In June 2008, the Veteran additionally stated that he struck an officer during this event. In November 2008, the Veteran stated for the first time that he underwent a major operation following this event. In April 2009, the Veteran stated for the first time that he saw "dead bodies" in Germany before the hatch hit him on the head. Lay statements submitted in August and October 2009, themselves based on the Veteran's own accounts, indicated that the Veteran witnessed the violent deaths of other soldiers in the 1971 incident. In October 2009, the Veteran stated that he almost died as a result of this incident. In August 2010, the Veteran stated that he witnessed the deaths of other soldiers through binoculars, and he was treated in a special hospital devoted only to head injury. Accordingly, upon review of the evidence of record, the Board finds that the Veteran's account of his in-service experience lacks credibility because the fundamental details of the Veteran's account of his in- service experience has changed dramatically over time, from involving only a head injury to involving witnessing the deaths of other soldiers. The Board finds that the Veteran's description of his 1971 in-service stressor lacks credibility not only because it inconsistent, but it is also is contradicted by other evidence of record. The Board finds it implausible that the Veteran's service treatment records would contain no documentation of the Veteran's 1971 injury and the "major operation" that followed such injury. The Veteran's January 1971 service separation examination showed normal clinical results, and the Veteran did not self-report this injury in any subsequent Report of Medical History. The Veteran self- reported in 1976 and 1980 that he had been hospitalized for an appendix removal. The Board finds it to be incredible that the Veteran would not have reported a major head operation from 1971, had the 1971 incident actually occurred. In 2005 and 2006 psychiatric evaluations, the Veteran did not mention the occurrence of the 1971 event at all, which the Board finds to be inconsistent with the Veteran's current allegations that assign great psychological import to the 1971 incident. The Board must also note that the Veteran's treating clinicians have often questioned the Veteran's credibility. For example, in December 2008, an examiner found that the Veteran exaggerated his symptoms. The Board acknowledges that the record contains lay statements from others who purported to have either witnessed or heard the Veteran's account of the 1971 hatch incident. Given the inconsistencies and contradictions set forth above, however, the Board affords these lay statements with very little probative weight. In addition to the Veteran's own allegations, the Board has considered as part of its credibility analysis VA treatment records that either indicate that the Veteran suffered from an in-service trauma or indicate that the Veteran's PTSD is related to the 1971 in-service trauma. The question of whether the Veteran was exposed to a stressor in service is a factual one and VA adjudicators are not bound to accept uncorroborated accounts of stressors or medical opinions based upon such accounts. Wood v. Derwinski, 1 Vet. App. 190 (1991). Whether a claimed stressor is of sufficient gravity to cause or support a diagnosis of PTSD is a decision that is medical in nature. Whether a claimed stressor actually occurred is a question of fact for adjudicators. The VA opinions that suggest that the Veteran experienced an 1971 in-service trauma are based on the Veteran's own account of an in-service stressor that is otherwise unverified. Those VA opinions do not identify any specific supporting evidence corroborating the 1971 incident. The Board therefore does not find that the opinions lend additional credibility to the Veteran's account of the 1971 incident. The Board accordingly finds that the Veteran has not demonstrated the existence of the claimed in-service stressor from 1971. Accordingly, upon review of the entirety of the evidence of record, the Board finds that the weight of the evidence is against a finding that the Veteran experienced a 1971 in- service disease or injury. The Veteran's account of his in- service experiences is incredible for the reasons set forth above. The second Hickson element, in-service disease or injury (or or, using terminology applicable to PTSD, a "stressor"), is not met, and the Veteran's claim for service connection for an acquired psychiatric condition, to include PTSD, fails on this basis alone. The Board acknowledges that VA is statutorily required to resolve the benefit of the doubt in favor of the Veteran when there is an approximate balance of positive and negative evidence regarding the merits of an outstanding issue. The Board finds, however, that the benefit of the doubt is not applicable in this case because the preponderance of the evidence is against the claim. See 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). Analysis - 1985 Stressor With regard to the Veteran's other claimed stressor, a DD Form 2173, statement of medical examination and duty status, indicates that during an August 1985 period of ACDUTRA, the Veteran suffered left knee bruises during field exercises while seated as a passenger in a vehicle. The form states that the Veteran hit his knee when his truck collided with another truck. An individual sick slip indicates that the Veteran had bruises of his leg from a truck accident. In August 2005, the Veteran stated to a private psychiatric practice that his problems "started about 3 months after [the Veteran] got hurt unloading a truck in Oregon." In an August 2005 psychological evaluation for SSA benefits, the Veteran recounted neither of his in-service stressor events. The psychologist diagnosed the Veteran with depression and alcohol abuse. In a September 2005 psychiatric review for SSA benefits, the Veteran was diagnosed with depression and substance addiction disorders. A December 2005 notation indicated that the Veteran was "trying to get VA benefits . . . injured in military in 70's." In August 2006, C.S., a private mental health nurse practitioner, indicated that she had treated the Veteran for medication management for generalized anxiety disorder and bipolar disorder since August 2005. In December 2007, C.R., a private mental health nurse practitioner, indicated that the Veteran stated that he was involved in a four-truck collision in 1985 and required helicopter evacuation for medical treatment. In a December 2007 statement in support of his claim for service connection for PTSD, the Veteran stated that in 1985, he was traveling in a truck while wearing a gas mask. The Veteran indicated that he was attacked by the 82nd Airborne and lost visibility. The Veteran stated that "then each truck hit each other." The Veteran indicated that he "fell out" when the "door open[ed.]" The Veteran indicated that five other soldiers were hurt. In May 2008, the Veteran stated that in 1985, two trucks collided on a back road, and eight soldiers, including the Veteran, were taken to the hospital. The Veteran's left knee hit the dashboard, and the Veteran reported that he used a cane as a result of this incident. The Veteran stated that he was unable to drive a truck after that time. In November 2008, the Veteran indicated that he was involved in a major accident in 1985. The Veteran wore a gas mask while riding in a truck, and trucks then slammed into each other. The Veteran indicated that he went to a hospital. In December 2008 neuropsychological testing, an examiner found that the results of the Veteran's testing were invalid due to the Veteran's exaggeration of symptoms. The Veteran underwent a VA examination in April 2009. The Veteran stated that he witnessed a truck wreck in 1985 after being attacked by the 82nd Airborne in zero visibility. The Veteran indicated that he could not see and did not know if he was safe. In a July 2010 treatment record, the Veteran indicated that he was involved in a multiple-vehicle accident in 1985 during war games. The Veteran indicated that he was wearing a gas mask with low visibility and he was nearly run over by another truck when he was injured. The examiner indicated that the Veteran met the criteria for PTSD in terms of the stressors involved and the symptoms present. In his August 2010 hearing before the undersigned, the Veteran indicated that the event that occurred in 1985 was not as severe as the incident that occurred in 1971. Upon review of this evidence, the record demonstrates that the Veteran was indeed involved in a 1985 truck accident that resulted in a bruised knee, though the details associated with this event have changed substantially over time. The next question, therefore, is whether there is a link, established by medical evidence, between the Veteran's current symptoms and this in-service stressor. The Board finds that the weight of the evidence indicates that there is no such link. In January 2009, the Veteran provided an illegibly-signed statement from a nurse practitioner stating that the Veteran's PTSD was related to military accidents, including a truck wreck. In April 2009, a VA examiner found that the Veteran did not meet the DSM-IV criteria for a diagnosis of PTSD. The examiner found the Veteran's account of his in-service experiences to be unreliable. The examiner noted, as an example that the Veteran stated both that he could and could not see after the alleged 1985 incident. The Veteran stated both that he was in the truck wreck and not in the truck wreck. The Veteran variously stated that he was evacuated from the 1985 incident via helicopter, that he sought treatment the next day, and that he sought treatment a week later. The Veteran stated that there were no fatalities from this accident. The Veteran's life was not threatened. The examiner noted that the training exercise itself may have been frightening, but this incident was not sufficiently frightening to warrant the stress response that he has described. The examiner found that the Veteran's assertion that he developed PTSD as a result of the 1985 exercise was not supported by the fact that he remained a truck driver until he retired medically, and he remained in Reserve service until his time ran out. Furthermore, by the Veteran's own report, the Veteran did not seek out psychiatric treatment until 2004. The examiner found that the Veteran presented an inconsistent history and has documented invalid testing on psychometric testing, which the examiner found to be suggestive of malingering. In April 2010, a VA examiner noted that the Veteran's diagnosis of PTSD was made without the benefit of review of the Veteran's claims file. The examiner indicated that the Veteran's PTSD diagnosis was based on the Veteran's report of injury that was not supported by evidence in the claims file. Furthermore, the examiner noted that the Veteran also stated that he had problems relating to a truck accident in 1985. The examiner noted that the Veteran was examined at that time, found to have a bruised knee, and released back to full duty that day. In subsequent descriptions, the Veteran gave conflicting information regarding what happened. Based on the description of injuries resulting from the accident, the examiner noted that while the accident was frightening, it did not rise to the level of severity that would qualify for trauma supporting a diagnosis of PTSD. Further, the Veteran's report of continuing to work as a truck driver for many years following the accident is not consistent with a diagnosis of PTSD. Given all of these considerations, the examiner did not find enough evidence to support the claim that a qualifying trauma occurred, thus the Veteran did not qualify for a diagnosis of PTSD. In a July 2010 treatment record, a VA clinician indicated that the Veteran met the criteria for PTSD in terms of the stressors involved and the symptoms present. In a January 2013 VA examination, the examiner noted that the Veteran underwent a formal PTSD evaluation in 2007, which was the first time that the Veteran claimed trauma relating to in- service incidents. The examiner also noted that the Veteran first underwent psychiatric treatment in 2005, at which time the Veteran did not mention his 1985 motor vehicle accident. The examiner noted that while the 1985 incident occurred, the only injury to the Veteran was a bruising of his knee. The only record of treatment after this event was a note of bruising when the Veteran presented for treatment a week after the incident. There was no indication that anyone else was hurt or killed in this event. The examiner noted that at various times, the Veteran claimed that the accident was much more serious than was reflected in the line of duty report. For example, the examiner noted that the Veteran had claimed to have been in a "multiple truck accident," was "nearly run over," and was "thrown from the vehicle." Each of these statements is inconsistent with the line of duty determination. The examiner found that the event that the Veteran experienced in 1985, while likely distressing, was not a stressor sufficient to support a diagnosis of PTSD. Accordingly, while the Board observes that some of the Veteran's medical treatment records indicate that the Veteran suffers from PTSD as a result of the 1985 in-service incident, it must agree with the finding of the April 2010 VA examiner that such opinions were made without review of the Veteran's claims file. The Board affords conclusions that are based only upon the Veteran's own descriptions of the severity of the 1985 in-service event with very little probative weight. Similarly, the Board affords the January 2009 illegibly-signed statement stating that the Veteran's PTSD was related to military accidents with little probative weight. Not only does such statement appear to be based on the Veteran's own statements, but it contains no rationale for its conclusion. The Board affords the medical opinions of the April 2009, April 2010, and July 2013 VA examiners with more probative weight because their conclusions are accompanied by a rationale, and the examiners reviewed the Veteran's claims file before arriving at a conclusion. To the extent that the Veteran himself believes that his acquired psychiatric condition is related to his 1985 in- service event, the Board acknowledges that the Veteran is competent to provide testimony concerning factual matters of which he has first-hand knowledge. See, e.g., Barr v. Nicholson, 21 Vet. App. 303 (2007); Washington v. Nicholson, 19 Vet. App. 362 (2005). Further, under certain circumstances, lay statements may support a claim for service connection by supporting the occurrence of lay- observable events or the presence of disability, or symptoms of disability, susceptible of lay observation. See Davidson v. Shinseki, 581 F.3d 1313 (Fed. Cir. 2009); Jandreau v. Nicholson, 492 F.3d 1372 (Fed. Cir. 2007). Although lay persons are competent to provide opinions on some medical issues, see Kahana v. Shinseki, 24 Vet. App. 428, 435 (2011), as to the specific issue in this case, namely, the etiology of an acquired psychiatric disorder, the issue of causation of a psychiatric condition is a medical determination outside the realm of common knowledge of a lay person. See Jandreau v. Nicholson, 492 F.3d 1372, 1377 n.4 (Fed. Cir. 2007) (lay persons not competent to diagnose cancer). Thus, although the Board has carefully considered the lay contentions of record suggesting that the Veteran's acquired psychiatric condition is related to his military service, the Board ultimately affords the weight of the objective medical evidence of record, which fails to find a connection between the Veteran's acquired psychiatric condition and his military service, with greater probative weight than these lay opinions. There is also no evidence showing or suggesting that the Veteran developed a psychosis within one year of separation from active duty service, which would justify entitlement to service connection on a presumptive basis. Instead, the post-service evidence indicates that the Veteran was not diagnosed with an acquired psychiatric condition until many years after the Veteran was released from active duty service. As such, in the absence of diagnosis of a mental disorder within one year of separation from service, presumptive service connection must be denied. Similarly, with regard to a continuity of symptomatology, even assuming that the Veteran's current acquired psychiatric condition is a "psychosis," the Board finds that the long lapse in time between the Veteran's active service and the first medical treatment for an acquired psychiatric disorder weighs against the Veteran's claim of a continuity of symptomatology since his separation from service. The Board may, and will, consider in its assessment of a service connection the passage of a lengthy period of time during which the Veteran has not complained of the malady at issue. See Maxson v. West, 12 Vet. App. 453, 459 (1999), aff'd sub nom. Maxson v. Gober, 230 F.3d 1330, 1333 (Fed. Cir. 2000). Therefore, service connection based on a continuity of symptomatology is also unwarranted. Accordingly, upon review of the entirety of the evidence of record, the Board finds that the weight of the evidence is against a finding that the Veteran's 1985 stressor is related to his current psychiatric symptoms. The third Hickson element, in-service disease or injury, is not met, and the Veteran's claim for service connection for an acquired psychiatric condition, to include PTSD, fails on this basis alone. The Board acknowledges that VA is statutorily required to resolve the benefit of the doubt in favor of the Veteran when there is an approximate balance of positive and negative evidence regarding the merits of an outstanding issue. The Board finds, however, that the benefit of the doubt is not applicable in this case because the preponderance of the evidence is against the claim. See 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). ORDER Service connection for a left knee disorder is denied. Service connection for a psychiatric disorder, to include PTSD, is denied. ____________________________________________ F.
