Posttraumatic stress disorder (PTSD) is a psychiatric disorder that may occur in people who have experienced or witnessed a traumatic event such as a natural disaster, a serious accident, a terrorist act, war/combat, or rape or who have been threatened with death, sexual violence or serious injury.
PTSD can occur in all people, of any ethnicity, nationality or culture, and at any age. PTSD affects approximately 3.5 percent of U.S. adults every year, and an estimated one in 11 people will be diagnosed with PTSD in their lifetime. Women are twice as likely as men to have PTSD. Three ethnic groups – U.S. Latinos, African Americans, and American Indians – are disproportionately affected and have higher rates of PTSD than non-Latino whites.
People with PTSD have intense, disturbing thoughts and feelings related to their experience that last long after the traumatic event has ended. They may relive the event through flashbacks or nightmares; they may feel sadness, fear or anger; and they may feel detached or estranged from other people. People with PTSD may avoid situations or people that remind them of the traumatic event, and they may have strong negative reactions to something as ordinary as a loud noise or an accidental touch.
A diagnosis of PTSD requires exposure to an upsetting traumatic event. However, the exposure could be indirect rather than first hand. For example, PTSD could occur in an individual learning about the violent death of a close family or friend. It can also occur as a result of repeated exposure to horrible details of trauma such as police officers exposed to details of child abuse cases.
SYMPTOMS OF PTSD
Symptoms of PTSD fall into four categories. Specific symptoms can vary in severity.
Intrusive thoughts such as repeated, involuntary memories; distressing dreams; or flashbacks of the traumatic event. Flashbacks may be so vivid that people feel they are re-living the traumatic experience or seeing it before their eyes.
Avoiding reminders of the traumatic event may include avoiding people, places, activities, objects and situations that may trigger distressing memories. People may try to avoid remembering or thinking about the traumatic event. They may resist talking about what happened or how they feel about it.
ALTERATIONS IN COGNITION OR MOOD
Inability to remember important aspects of the traumatic evet, negative thoughts and feelings leading to ongoing and distorted beliefs about oneself or others (e.g., “I am bad,” “No one can be trusted”); distorted thoughts about the cause or consequences of the event leading to wrongly blaming self or other; ongoing fear, horror, anger, guilt or shame; much less interest in activities previously enjoyed; feeling detached or estranged from others; or being unable to exprience positive emotions (a void of happiness or satisfation).
ALTERATIONS IN AROUSAL AND REACTIVITY
Arousal and reactive symptoms may include being irritable and having angry outbursts; behaving recklessly or in a self-destructive way; being overly watchful of one's surroundings in a suspecting way; being easily startled; or having problems concentrating or sleeping.
It is important to note that not everyone who experiences trauma develops PTSD, and not everyone who develops PTSD requires psychiatric treatment. For some people, symptoms of PTSD subside or disappear over time. Others get better with the help of their support system (family, friends or clergy). But many people with PTSD need professional treatment to recover from psychological distress that can be intense and disabling. It is important to remember that trauma may lead to severe distress. That distress is not the individual’s fault, and PTSD is treatable. The earlier a person gets treatment, the better chance of recovery.
Psychiatrists and other mental health professionals use various effective (research-proven) methods to help people recover from PTSD. Both talk therapy (psychotherapy) and medication provide effective evidence-based treatments for PTSD. One category of psychotherapy, cognitive behavior therapies (CBT), is very effective. Cognitive processing therapy, prolonged exposure therapy and stress inoculation therapy (described below) are among the types of CBT used to treat PTSD.
