Learn why a veteran's claim for obstructive sleep apnea, including secondary to tinnitus and TERA, was denied by the BVA due to lack of nexus evidence and unfavorable medical opinions.
This case involves a Marine Corps veteran who served from 1977 to 1984, including deployments to Turkey as an air traffic controller with shift work. The veteran also served at Camp Lejeune for over 30 days, qualifying them for presumed toxic exposure risk activity (TERA). Years after service, the veteran was diagnosed with obstructive sleep apnea (OSA) and filed a claim for service connection. The veteran argued for service connection on three fronts: first, directly due to their demanding shift work during service, citing studies linking shift work to sleep apnea. Second, they claimed OSA was secondary to their already service-connected tinnitus, arguing that constant ringing in the ears disrupts sleep and contributes to OSA. Third, they sought service connection due to their TERA exposure at Camp Lejeune, which VA conceded they had. Despite the veteran's arguments and the presence of a current OSA diagnosis, the Board of Veterans' Appeals (BVA) denied all three claims. The BVA found no evidence of OSA symptoms during service, noting clear in-service medical records that showed no sleep issues. For the TERA claim, a VA examiner concluded the veteran's OSA was obstructive, not central (which might be linked to TERA), and more likely caused by factors like excess weight and anatomy. For the secondary claim to tinnitus, a VA examiner also found no direct link. The Board ultimately sided with the VA's medical opinions, concluding that the evidence persuasively weighed against a connection between the veteran's OSA and their military service, TERA exposure, or service-connected tinnitus.
To win a claim like this, especially when there's a long gap between service and diagnosis, the veteran needs to focus heavily on providing strong medical evidence that establishes a 'nexus' – a direct link – between their service and their current condition. For direct service connection, even without a formal in-service diagnosis, the veteran should gather detailed lay statements (their own and from buddies or family) describing symptoms of sleep apnea (like loud snoring, gasping, daytime sleepiness, frequent awakenings) that occurred during service and continued after. These statements should be as specific as possible, including dates, locations, and how the symptoms affected their daily life. Crucially, the veteran needs a favorable medical opinion from a private doctor or a VA doctor (if they can get one) that directly refutes the VA's negative opinions. This opinion must review the entire claims file, including service records, post-service medical records, and lay statements. The doctor should explain, using sound medical principles and literature, how the veteran's in-service experiences (like shift work or specific exposures) or their service-connected conditions (like tinnitus) caused or aggravated their obstructive sleep apnea. For TERA, the opinion would need to specifically address why the veteran's obstructive sleep apnea *could* be linked to their exposure, perhaps by challenging the VA examiner's distinction between obstructive and central apnea in this specific context, or by identifying other mechanisms. If the veteran has new and relevant evidence (like a strong private medical opinion or new lay statements), they should file a Supplemental Claim (VA Form 20-0995). This allows VA to reconsider the claim with the new evidence. The key is to directly address the reasons for denial, especially the lack of nexus and the VA's medical opinions, with compelling evidence that fills those gaps.
To service connect a condition like sleep apnea, especially years after service, you must provide strong medical evidence (a 'nexus opinion') directly linking your current condition to your military service, a service-connected disability, or a toxic exposure, and demonstrate continuity of symptoms if possible.
