Post-Traumatic Stress Disorder (PTSD) is a mental health condition that can develop after a person experiences or witnesses a traumatic event. While it is often associated with combat veterans, PTSD can affect individuals of any age and background, according to Dr. James Reeves, a psychiatrist with University Medical Center. Risk factors include a history of trauma, childhood neglect and pre-existing mental health conditions such as depression or anxiety. Common symptoms include flashbacks, nightmares, avoidance of reminders of the trauma, insomnia and changes in mood or thinking. These symptoms can significantly impact daily life, relationships and a person’s sense of identity and safety.
