PTSD

What is PTSD?

Post-traumatic stress (PTSD) is a common anxiety disorder that develops after exposure to a terrifying event or ordeal in which grave physical harm occurred or was threatened. Family members of victims also can develop the disorder. PTSD can occur in people of any age, including children and adolescents. Depression, alcohol or other substance abuse, or other anxiety disorders frequently co-occur with PTSD.

The diagnosis of PTSD requires that one or more symptoms from each of the following categories be present for at least a month and that the symptom or symptoms must seriously interfere with leading a normal life:

  • Reliving the event through upsetting thoughts, nightmares or flashbacks, or having very strong mental and physical reactions if something reminds the person of the event.
  • Avoiding activities, thoughts, feelings or conversations that remind the person of the event; feeling numb to one’s surroundings; or being unable to remember details of the event.
  • Having a loss of interest in important activities, feeling all alone, being unable to have normal emotions or feeling that there is nothing to look forward to in the future may also be experienced.
  • Feeling that one can never relax and must be on guard all the time to protect oneself, trouble sleeping, feeling irritable, overreacting when startled, angry outbursts or trouble concentrating.

Traumatic events that may trigger PTSD include violent personal assaults, natural or human-caused disasters, accidents, or military combat. Among those who may experience PTSD are: survivors of accidents (for example road traffic accidents); victims of rape, physical and sexual abuse; victims of other crimes; troops who served in the Gulf Wars, Iraq or Afghanistan; rescue workers involved in the aftermath of disasters; and people who have witnessed traumatic events.

Many people with PTSD repeatedly re-experience the ordeal in the form of flashback episodes, memories, nightmares, or frightening thoughts, especially when they are exposed to events or objects reminiscent of the trauma. Anniversaries of the event can also trigger symptoms. People with PTSD also experience emotional numbness and sleep disturbances, depression, anxiety, and irritability or outbursts of anger. Feelings of intense guilt are also common. Most people with PTSD try to avoid any reminders or thoughts of the ordeal.

Physical symptoms such as headaches, gastrointestinal distress, immune system problems, dizziness, chest pain, or discomfort in other parts of the body are common in people with PTSD. Often, these symptoms may be treated without the recognition that they stem from an anxiety disorder.

PTSD can be successfully treated using eye movement, desensitization and reprocessing (EMDR) or cognitive behavioural therapy (CBT).
