Post-traumatic stress disorder, or PTSD, affects hundreds of thousands of veterans. According to the Mayo Clinic, this mental health condition is triggered by a terrifying event-either experiencing it or witnessing it. Symptoms may include flashbacks, nightmares and severe anxiety, as well as uncontrollable thoughts about the event. This 30-minute documentary, produced by Canton resident Ron Ponder, talks about some of the research and treatments of veterans and the general public of today.
