Entitlement to service connection for an acquired psychiatric disability is denied.

Board reasoning

The Board weighed the evidence showing no in-service onset and no nexus between current psychiatric symptoms and military service, instead attributing symptoms to psychosocial stressors and non-service-related factors. The most probative medical opinions, including the September 2025 examination, concluded no direct causation or aggravation by service-connected conditions, and the Board found the secondary service connection theories unpersuasive given consistent non-service explanations.
