Panic attacks and panic disorder



A panic attack is a sudden episode of intense fear that develops for no apparent reason and that triggers severe physical reactions. Panic attacks can be very frightening. When panic attacks occur, you might think you're losing control, having a heart attack or even dying.

You may have only one or two panic attacks in your lifetime. But if you have panic attacks frequently, it could mean that you have panic disorder, a type of chronic anxiety disorder.

Panic attacks were once dismissed as nerves or stress, but they're now recognized as a real medical condition. Although panic attacks can significantly affect your quality of life, treatment — including medications, psychotherapy and relaxation techniques to help prevent or control panic attacks — is very effective.

Symptoms


Panic attack symptoms can make your heart pound and cause you to feel short of breath, dizzy, nauseated and flushed. Because panic attack symptoms can resemble life-threatening conditions, it's important to seek an accurate diagnosis and treatment.

Panic attack symptoms can include:
Rapid heart rate
Sweating
Trembling
Shortness of breath
Hyperventilation
Chills
Hot flashes
Nausea
Abdominal cramping
Chest pain
Headache
Dizziness
Faintness
Tightness in your throat
Trouble swallowing
A sense of impending death

You may have a few or many of these panic attack symptoms. Panic attacks typically begin suddenly, without warning. Panic attack symptoms usually peak within 10 minutes and last about half an hour. But panic attacks have many variations. They may last hours or, on rare occasions, up to a day. You may feel fatigued and worn out after a panic attack subsides. One of the worst things about panic attacks is the intense fear that you'll have another panic attack.

If you have frequent panic attacks, you may have a condition called panic disorder. Panic attacks can greatly interfere with your life — and perhaps even endanger you or others.

Panic attacks can strike at almost any time without warning — when you're driving the school car pool, at the mall, sound asleep or in the middle of a business meeting. And you may fear having a panic attack so much that you avoid situations where they may occur. You may even be unable to leave your home (agoraphobia), because no place feels safe.

Causes


It's not known what causes panic attacks or panic disorder. Things that may play a role include:
Genetics
Stress
Certain changes in the way parts of your brain function

Some research suggests that your body's natural fight-or-flight response to danger is involved in panic attacks. For example, if a grizzly bear came after you, your body would react instinctively. Your heart rate and breathing would speed up as your body prepared itself for a life-threatening situation. Many of the same reactions occur in a panic attack. But it's not known why a panic attack occurs when there's no obvious danger present
