Post-traumatic stress disorder (PTSD), once called shell shock or battle fatigue syndrome, is a serious condition that can develop after a person has experienced or witnessed a traumatic or terrifying event in which serious physical harm occurred or was threatened, and in more serious cases, death was perceived as imminent. PTSD is a lasting consequence of traumatic ordeals that may cause intense fear, helplessness, or anxiety, such as a sexual or physical assault, the unexpected death of a loved one, an accident, war, or natural disaster. Families of victims can also develop post-traumatic stress disorder, as can emergency personnel, rescue workers fire fighters and police officers.
Most people who experience a traumatic event will have reactions that may include shock, anger, nervousness, fear, and even guilt. These reactions are common; and for most people, they go away over time. For a person with PTSD, however, these feelings continue and even increase, becoming so strong that they keep the person from living a normal life. People with PTSD have symptoms for longer than one month and cannot function as well as before the event occurred.
Symptoms of PTSD most often begin within three months of the event. In some cases, however, they do not begin until years later. The severity and duration of the illness vary. Some people recover within six months, while others suffer much longer.
Symptoms of PTSD often are grouped into three main categories, including:
Everyone reacts to traumatic events differently. Each person is unique in their ability to manage fear and stress, and to cope with the threat posed by a traumatic event or situation. For that reason, not everyone who experiences or witnesses a trauma will develop PTSD. Further, the type of help and support a person receives from friends, family members and professionals following the trauma may influence the development or non-development of PTSD as well as the severity of symptoms.
PTSD was first brought to the attention of the medical community by war veterans, hence the names shell shock and battle fatigue syndrome. However, PTSD can occur in anyone who has experienced a traumatic life threatening event. People who have been abused as children or who have been repeatedly exposed to life-threatening situations are at greater risk for developing PTSD and other anxiety related illnesses.[1]
The lifetime prevalence of PTSD is 8% in the United States.[2]
On a population scale, PTSD can occur following natural or man-made disasters.[3] PTSD has been noted following the Indian Ocean tsunami in 2004 and hurricane Katrina in 2005. [3]
