PTSD

Posttraumatic stress disorder (PTSD) is a mental disorder that can develop after a person is exposed to a traumatic event, such as sexual assault, warfare, traffic collisions, child abuse, or other threats on a person's life. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in how a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event. Young children are less likely to show distress but instead may express their memories through play.

Symptoms

PTSD symptoms can generally be grouped into four types: intrusive memories, avoidance, negative changes in thinking and mood, and changes in physical and emotional reactions. Symptoms can vary over time or vary from person to person.

Intrusive memories

Symptoms of intrusive memories may include:

• Recurrent, unwanted distressing memories of the traumatic event
• Reliving the traumatic event as if it were happening again (flashbacks)
• Upsetting dreams or nightmares about the traumatic event
• Severe emotional distress or physical reactions to something that reminds you of the traumatic event

Avoidance

Symptoms of avoidance may include:

• Trying to avoid thinking or talking about the traumatic event
• Avoiding places, activities or people that remind you of the traumatic event

Negative changes in thinking and mood

Symptoms of negative changes in thinking and mood may include:

• Negative feelings about yourself or other people
• Inability to experience positive emotions
• Feeling emotionally numb
• Lack of interest in activities you once enjoyed
• Hopelessness about the future
• Memory problems, including not remembering important aspects of the traumatic event
• Difficulty maintaining close relationships

Changes in physical and emotional reactions

Symptoms of changes in physical and emotional reactions (also called arousal symptoms) may include:

• Being easily startled or frightened
• Always being on guard for danger
• Self-destructive behavior, such as drinking too much or driving too fast
• Trouble sleeping
• Trouble concentrating
• Irritability, angry outbursts or aggressive behavior
• Overwhelming guilt or shame

Causes

PTSD is believed to be caused by experiencing any of a wide range of events which produces intense negative feelings of "fear, helplessness, or horror" in the observer or participant. Sources of such feelings may include (but are not limited to):

• Experiencing or witnessing childhood or adult physical, emotional or sexual abuse.
• Experiencing or witnessing physical assault, adult experiences of sexual assault, accidents, drug addiction, illnesses, medical complications.
• Employment in occupations exposed to war (such as soldiers) or disaster (such as emergency service workers).
• Getting a diagnosis of a life-threatening illness.

Treatment

Treatment for PTSD may involve therapeutic methods such as cognitive behavioral therapy, group therapy, and exposure therapy. In some cases, medication may be prescribed to help manage symptoms.
