Mental health conditions are among the most common service-connected disabilities the VA evaluates, yet they are also some of the most challenging to prove. Unlike a visible physical injury, PTSD, depression, and anxiety do not show up on an X-ray. The VA relies heavily on clinical diagnoses, treatment records, and detailed descriptions of how symptoms affect your work, relationships, and daily functioning.
For PTSD specifically, the VA requires a stressor — an event during service that caused trauma. Combat veterans can often verify stressors through deployment records, but non-combat veterans may need to provide additional documentation such as incident reports, statements from fellow servicemembers, or news reports. A PTSD diagnosis from a VA or private mental health professional is essential, and the more detailed the treatment notes, the stronger your claim.
Depression and anxiety claims follow a similar pattern. The VA looks for a current diagnosis, evidence of symptoms during or after service, and a medical opinion linking the condition to your military experience. Symptom journals can be surprisingly effective: documenting sleep disturbances, panic episodes, concentration problems, and social withdrawal over time gives the VA concrete examples to reference.
During a C&P exam for mental health, be honest about your worst days, not just your best. Examiners are trained to assess frequency, severity, and duration of symptoms. If the rating feels too low, consider whether a higher percentage is supported by your symptoms — for example, total occupational and social impairment may qualify for a 100% rating, while intermittent inability to perform occupational tasks may warrant 70%.
