What are panic attacks?

Panic attacks may be symptoms of an anxiety disorder. These attacks are a serious health problem in the U.S. At least 1.7% of adult Americans, or about 3 million people, will have panic attacks at some time in their lives, with the peak age at which people have their first panic attack (onset) being 15 to 19 years.

Another fact about panic is that this symptom is strikingly different from other types of anxiety; panic attacks are so very sudden and often unexpected, appear to be unprovoked, and are often disabling.

Once someone has had a panic attack, for example, while driving, shopping in a crowded store, or riding in an elevator, he or she may develop irrational fears, called phobias, about these situations and begin to avoid them.

Eventually, the pattern of avoidance and level of anxiety about another attack may reach the point where the mere idea of doing things that preceded the first panic attack triggers future panic attacks, resulting in the individual with panic disorder being unable to drive or even step out of the house.
