A trauma-and-stress-related disorder linked to traumatic or terrifying event(s) and causing recurring affective / behavioral / cognitive responses. Responses are triggered by events associated with the original trauma, with symptoms lasting at least a month and often longer. Symptoms are variable but are characterized by obsessive negative thoughts, bad dreams, flashbacks, irritability, aggressiveness, fearfulness, dissociation, avoidance behaviors, sleep disturbance, lack of interest, hypervigilance, and poor concentration as well as physical symptoms such as rapid breathing, increased heart rate, sweating, and tremors.

Trauma experienced may be from violence, physical abuse, sexual assault, witnessing a violent act, or experiencing severe pain, combat, torture, or acts of terrorism. It may result in impairment and loss of quality of life. It may be associated with traumatic brain injury and myocardial infarction.

Management includes pharmacotherapy, counseling, and behavioral therapy.
