PTSD is a biopsychological condition associated with very stressful or life-threatening events. 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 has been extensive, in part because of the incidence among military personnel who served in Iraq and Afghanistan. But beyond the military, PTSD can directly affect survivors of stressful events such as abuse, rape, physical violence, severe accidents, and natural disasters. People may even experience PTSD following some medical procedures. Beyond such direct effects, PTSD affects the families and loved ones of PTSD sufferers. 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.
