Post traumatic stress disorder is an anxiety disorder that develops following frightening, stressful, or distressing life events. Characterized by intense fear, helplessness, stress, and avoidance. PTSD affects normal life and functioning of the patient. Treatments include medications and psychotherapy, either alone or in combination.

It is important to note that PTSD is different from just feeling afraid or anxious. PTSD is commonly seen in individuals who have experienced war, traumatic events (past and present), those who have been the victims of assault, and those who work in close proximity to violence, teachers, emergency personnel, children etc.
