What is the biological basis of PTSD? What occurs in the brain and nervous system that apparently gives rise to PTSD symptoms?
Application: PTSD
Post-traumatic stress disorder (PTSD) is a biopsychological condition associated with very stressful or life-threatening events such as abuse, rape, violence, military combat, severe accidents, and natural disasters. Symptoms include having intrusive thoughts about or reliving the event(s), withdrawing from others, and experiencing anxiety or hyperarousal for weeks or months following the event(s). People with PTSD may turn to drugs or alcohol to help them cope, they may exhibit signs of depression, their relationships may deteriorate, and they may manifest physical symptoms.
PTSD has been studied intensively among veterans and active military personnel since at least World War II. In recent times, media coverage of PTSD is extensive, in part because of the incidence among military personnel who served in Iraq (according to the video “The Soldier’s Heart,” the rate is 1 in 6). With such a large segment of the population experiencing or at risk for PTSD, it is important to raise awareness about the symptoms, consequences, and treatment.
