Clinical Information

• A class of traumatic stress disorders with symptoms that last more than one month. There are various forms of post-traumatic stress disorder, depending on the time of onset and the duration of these stress symptoms. In the acute form, the duration of the symptoms is between 1 to 3 months. In the chronic form, symptoms last more than 3 months. With delayed onset, symptoms develop more than 6 months after the traumatic event.
• Acute, chronic, or delayed reactions to traumatic events such as military combat, assault, or natural disaster.
• An anxiety disorder precipitated by an experience of intense fear or horror while exposed to a traumatic (especially life-threatening) event. The disorder is characterized by intrusive recurring thoughts or images of the traumatic event; avoidance of anything associated with the event; a state of hyperarousal and diminished emotional responsiveness. These symptoms are present for at least one month and the disorder is usually long-term.
• An anxiety disorder that develops in reaction to physical injury or severe mental or emotional distress, such as military combat, violent assault, natural disaster, or other life-threatening events. Having cancer may also lead to post-traumatic stress disorder. Symptoms interfere with day-to-day living and include reliving the event in nightmares or flashbacks; avoiding people, places, and things connected to the event; feeling alone and losing interest in daily activities; and having trouble concentrating and sleeping.
• Post-traumatic stress disorder (PTSD) is a real illness. You can get PTSD after living through or seeing a traumatic event, such as war, a hurricane, rape, physical abuse or a bad accident. Ptsd makes you feel stressed and afraid after the danger is over. It affects your life and the people around you. Ptsd can cause problems like
  • flashbacks, or feeling like the event is happening again
  • trouble sleeping or nightmares
  • feeling alone
  • angry outbursts
  • feeling worried, guilty or sad
  PTSD starts at different times for different people. Signs of PTSD may start soon after a frightening event and then continue. Other people develop new or more severe signs months or even years later. Ptsd can happen to anyone, even children. Medicines can help you feel less afraid and tense. It might take a few weeks for them to work. Talking to a specially trained doctor or counselor also helps many people with PTSD. This is called talk therapy.
