Post-traumatic stress disorder (PTSD), is a severe anxiety disorder characterized by flashbacks, nightmares, avoidance to stimuli that induces memories of the trauma, increased arousal, hyper vigilance, anger, and sleep deprivation through insomnia or other disturbances. PTSD occurs in victims that have been through psychological trauma, usually through an event involving death threats to oneself or others. Traumatic events may involve physical, sexual, or psychological abuse, which overwhelms the individual's coping mechanism.
The afflicted suffer from enduring symptoms, often requiring medical intervention to suppress distressful symptoms. A formal diagnosis should be obtained if one or more of the symptoms last more than one month. Post-traumatic stress disorder can cause significant impairment in an individual's social, occupational, and inter-relational aspects of their lives. While commonly associated with war veterans due to its association with bodily fatigue, other victims outside of the military may experience PTSD, including terrorist victims, inmates, mistreated children, whether mentally, physical or sexually abused, survivors of a natural disaster, and individuals who have been bullied.
