The Veterans Health Administration (VHA) reports that veterans under treatment for post-traumatic stress disorder (PTSD) often have one or more accompanying psychiatric conditions. According to a review of records from 2012, 70.2% of VHA patients with PTSD had at least one co-existing psychiatric condition, while a third of all PTSD patients had two or more additional mental health issues, with anxiety disorder and major depressive disorder being the most common.
