What is PTSD?

Post-Traumatic Stress Disorder (PTSD) is a debilitating condition that follows a terrifying event. Often, people with PTSD have persistent frightening thoughts and memories of their ordeal and feel emotionally numb, especially with people they were once close to. PTSD, once referred to as shell shock or battle fatigue, was first brought to public attention by war veterans, but it can result from any number of traumatic incidents. These include kidnapping, serious accidents such as car or train wrecks, natural disasters such as floods or earthquakes, violent attacks such as a mugging, rape, or torture, or being held captive. The event that triggers it may be something that threatened the person's life or the life of someone close to him or her. Or it could be something witnessed, such as mass destruction after a plane crash.

Whatever the source of the problem, some people with PTSD repeatedly relive the trauma in the form of nightmares and disturbing recollections during the day. They may also experience sleep problems, depression, feeling detached or numb, or being easily startled. They may lose interest in things they used to enjoy and have trouble feeling affectionate. They may feel irritable, more aggressive than before, or even violent. Seeing things that remind them of the incident may be very distressing, which could lead them to avoid certain places or situations that bring back those memories. Anniversaries of the event are often very difficult.

PTSD can occur at any age, including childhood. The disorder can be accompanied by depression, substance abuse, or anxiety. Symptoms may be mild or severe—people may become easily irritated or have violent outbursts. In severe cases they may have trouble working or socializing. In general, the symptoms seem to be worse if the event that triggered them was initiated by a person—such as a rape, as opposed to a flood.

Ordinary events can serve as reminders of the trauma and trigger flashbacks or intrusive images. A flashback may make the person lose touch with reality and reenact the event for a period of seconds or hours or, very rarely, days. A person having a flashback, which can come in the form of images, sounds, smells, or feelings, usually believes that the traumatic event is happening all over again.

Not every traumatized person gets full-blown PTSD, or experiences PTSD at all. PTSD is diagnosed only if the symptoms last more than a month. In those who do have PTSD, symptoms usually begin within 3 months of the trauma, and the course of the illness varies. Some people recover within 6 months, others have symptoms that last much longer. In some cases, the condition may be chronic. Occasionally, the illness doesn't show up until years after the traumatic event.

Quick Facts

Post-traumatic stress disorder (PTSD) is an extremely debilitating condition that can occur after exposure to a terrifying event or ordeal in which grave physical harm was threatened or occurred. Traumatic events that can trigger PTSD include violent personal assaults such as rape or mugging, natural or manmade disasters, car accidents, or military combat.

Most people with PTSD try to avoid any reminders or thoughts of the ordeal. Despite this avoidant behavior, 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. Symptoms of PTSD also include emotional numbness and sleep disturbances (including insomnia), depression, and irritability or outbursts of anger. Feelings of intense guilt are also common. PTSD is diagnosed only if these symptoms last more than one month.

Fortunately, through research supported by the National Institute of Mental Health (NIMH), effective treatments have been developed to help people with PTSD.

How Common Is PTSD?

About 4% of the population will experience symptoms of PTSD in a given year.

When Does PTSD Strike?

PTSD can develop at any age, including childhood. Symptoms of PTSD typically begin within 3 months following a traumatic event, although occasionally symptoms do not begin until years later. Once PTSD develops, the duration of the illness varies. Some people recover within 6 months while others may suffer much longer.

What Treatments Are Available for PTSD?

Treatment for PTSD includes cognitive-behavioral therapy, group psychotherapy, and medications (including antidepressants). Various forms of exposure therapy (such as systemic desensitization and imaginal flooding) have all been used with PTSD patients. Exposure treatment for PTSD involves repeated reliving of the trauma, under controlled conditions, with the aim of facilitating the processing of the trauma.

Can People with PTSD Also Have Other Physical or Emotional Illnesses?
People with PTSD can also have other psychological difficulties, particularly depression, substance abuse, or another anxiety disorder. The likelihood of treatment success is increased when these other conditions are appropriately diagnosed and treated, as well.

Treatment

Many people with anxiety disorders can be helped with treatment. Therapy for anxiety disorders often involves medication or specific forms of psychotherapy.
Medications, although not cures, can be very effective at relieving anxiety symptoms. Today, thanks to research by scientists at NIMH and other research institutions, there are more medications available than ever before to treat anxiety disorders. So if one drug is not successful, there are usually others to try. In addition, new medications to treat anxiety symptoms are under development.

For most of the medications that are prescribed to treat anxiety disorders, the doctor usually starts the patient on a low dose and gradually increases it to the full dose. Every medication has side effects, but they usually become tolerated or diminish with time. If side effects become a problem, the doctor may advise the patient to stop taking the medication and to wait a week—or longer for certain drugs—before trying another one. When treatment is near an end, the doctor will taper the dosage gradually.

Research has also shown that behavioral therapy and cognitive-behavioral therapy can be effective for treating several of the anxiety disorders.

Behavioral therapy focuses on changing specific actions and uses several techniques to decreases or stop unwanted behavior. For example, one technique trains patients in diaphragmatic breathing, a special breathing exercise involving slow, deep breaths to reduce anxiety. This is necessary because people who are anxious often hyperventilate, taking rapid shallow breaths that can trigger rapid heartbeat, lightheadedness, and other symptoms. Another technique—exposure therapy—gradually exposes patients to what frightens them and helps them cope with their fears.

Like behavioral therapy, cognitive-behavioral therapy teaches patients to react differently to the situations and bodily sensations that trigger panic attacks and other anxiety symptoms. However, patients also learn to understand how their thinking patterns contribute to their symptoms and how to change their thoughts so that symptoms are less likely to occur. This awareness of thinking patterns is combined with exposure and other behavioral techniques to help people confront their feared situations. For example, someone who becomes lightheaded during a panic attack and fears he is going to die can be helped with the following approach used in cognitive-behavioral therapy. The therapist asks him to spin in a circle until he becomes dizzy. When he becomes alarmed and starts thinking, "I'm going to die," he learns to replace that thought with a more appropriate one, such as "It's just a little dizziness—I can handle it."
