Phobias occur in several forms.  A specific phobia is a fear of a particular object or situation.  Social phobia is a fear of being painfully embarrassed in a social setting.  And agoraphobia, which often accompanies panic disorder, is a fear of being in any situation that might provoke a panic attack, or from which escape might be difficult if one occurred.

SPECIFIC PHOBIAS

Many people experience specific phobias, intense, irrational fears of certain  things or situations--dogs, closed-in places, heights, escalators, tunnels, highway driving, water, flying, and injuries involving blood are a few of the more common ones.  Phobias aren't just extreme fear; they are irrational fear.  You may be able to ski the world's tallest mountains with ease but panic going above the 10th floor of an office building.  Adults with phobias realize their fears are irrational, but often facing, or even thinking about facing, the feared object or situation brings on a panic attack or severe anxiety.

Specific phobias strike more than 1 in 10 people.  No one knows just what causes them, though they seem to run in families and are a little more prevelent in women.  Phobias usually first appear in adolescence or adullthood.  They start suddenly and tend to be more persistant than childhood phobias; only about 20% of adult phobias vanish on their own.  When children have specific phobias--for example, a fear of animals--those fears usually disappear over time, though they may continue into adulthood.  No one knows why they hang on in some people and disappear in others.

If the object of the fear is easy to avoid, people with phobias may not feel the need to seek treatment.  Sometimes, though, they may make important career or personal decisions to avoid phobic situations.

When phobias interfere with a person's life, treatment can help.  Successful treatment usually involves a kind of cognitive-behavioral therapy called desensitization or exposure therapy, in which patients are gradually exposed to what frightens them until the fear begins to fade.  Three-fourths of the patients benefit significantly from this type of treatment.  Relaxation and breathing exercises also help reduce anxiety symptoms.

There is currently no proven drug treatment for specific phobias, but sometimes certain medications may be prescribed to help reduce anxiety symptoms before someone faces a phobic situation.
