What is PTSD?

Understanding PTSD (PDF)

Posttraumatic stress disorder (PTSD) is an anxiety disorder that can occur after you have been through a traumatic event. A traumatic event is something horrible and scary that you see or that happens to you. During this type of event, you think that your life or others' lives are in danger. You may feel afraid or feel that you have no control over what is happening.

Anyone who has gone through a life-threatening event can develop PTSD. These events can include:

• Combat or military exposure
• Child sexual or physical abuse
• Terrorist attacks
• Sexual or physical assault
• Serious accidents, such as a car wreck
• Natural disasters, such as a fire, tornado, hurricane, flood, or earthquake

After the event, you may feel scared, confused, or angry. If these feelings don't go away or they get worse, you may have PTSD. These symptoms may disrupt your life, making it hard to continue with your daily activities.

How does PTSD develop?

All people with PTSD have lived through a traumatic event that caused them to fear for their lives, see horrible things, and feel helpless. Strong emotions caused by the event create changes in the brain that may result in PTSD.

Most people who go through a traumatic event have some symptoms at the beginning. Yet only some will develop PTSD. It isn't clear why some people develop PTSD and others don't. How likely you are to get PTSD depends on many things:

• How intense the trauma was or how long it lasted
• If you lost someone you were close to or were hurt
• How close you were to the event
• How strong your reaction was
• How much you felt in control of events
• How much help and support you got after the event

Many people who develop PTSD get better at some time. But about 1 out of 3 people with PTSD may continue to have some symptoms. Even if you continue to have symptoms, treatment can help you cope. Your symptoms don't have to interfere with your everyday activities, work, and relationships.

What are the symptoms of PTSD?

Symptoms of PTSD can be terrifying. They may disrupt your life and make it hard to continue with your daily activities. It may be hard just to get through the day.

PTSD symptoms usually start soon after the traumatic event, but they may not happen until months or years later. They also may come and go over many years. If the symptoms last longer than 4 weeks, cause you great distress, or interfere with your work or home life, you probably have PTSD.

There are four types of PTSD symptoms:

1. Reliving the event (also called re-experiencing symptoms)

Bad memories of the traumatic event can come back at any time. You may feel the same fear and horror you did when the event took place. You may have nightmares. You even may feel like you're going through the event again. This is called a flashback. Sometimes there is a trigger -- a sound or sight that causes you to relive the event. Triggers might include:

• Hearing a car backfire, which can bring back memories of gunfire and war for a combat Veteran.
• Seeing a car accident, which can remind a crash survivor of his or her own accident.
• Seeing a news report of a sexual assault, which may bring back memories of assault for a woman who was raped.
2. Avoiding situations that remind you of the event

You may try to avoid situations or people that trigger memories of the traumatic event. You may even avoid talking or thinking about the event. For example:

• A person who was in an earthquake may avoid watching television shows or movies in which there are earthquakes.
• A person who was robbed at gunpoint while ordering at a hamburger drive-in may avoid fast-food restaurants.
• Some people may keep very busy or avoid seeking help. This keeps them from having to think or talk about the event.
3. Feeling numb

You may find it hard to express your feelings. This is another way to avoid memories.

• You may not have positive or loving feelings toward other people and may stay away from relationships.
• You may not be interested in activities you used to enjoy.
• You may not be able to remember parts of the traumatic event or not be able to talk about them.
4. Feeling keyed up (also called hyperarousal)

You may be jittery, or always alert and on the lookout for danger. This is known as hyperarousal. It can cause you to:

• Suddenly become angry or irritable
• Have a hard time sleeping
• Have trouble concentrating
• Fear for your safety and always feel on guard
• Be very startled when something surprises you

What are other common problems?

People with PTSD may also have other problems. These include:

• Drinking or drug problems
• Feelings of hopelessness, shame, or despair
• Employment problems
• Relationships problems including divorce and violence
• Physical symptoms

Can children have PTSD?

Children can have PTSD too. They may have the symptoms described above or other symptoms depending on how old they are. As children get older, their symptoms are more like those of adults. Here are some examples of PTSD symptoms in children:

• Young children may become upset if their parents are not close by, have trouble sleeping, or suddenly have trouble with toilet training or going to the bathroom.
• Children who are in the first few years of elementary school (ages 6 to 9) may act out the trauma through play, drawings, or stories. They may complain of physical problems or become more irritable or aggressive. They also may develop fears and anxiety that don't seem to be caused by the traumatic event.

What treatments are available?

When you have PTSD, dealing with the past can be hard. Instead of telling others how you feel, you may keep your feelings bottled up. But treatment can help you get better.

There are good treatments available for PTSD

• Cognitive behavioral therapy (CBT) appears to be the most effective type of counseling for PTSD. There are different types of cognitive behavioral therapies such as cognitive therapy and exposure therapy.
• A similar kind of therapy called EMDR, or eye movement desensitization and reprocessing, is also used for PTSD.
• Medications can be effective too. A type of drug known as a selective serotonin reuptake inhibitor (SSRI), which is also used for depression, is effective for PTSD.
