Introduction to Phobias

Definition Of Phobia: 
Defined as a persistent and irrational fear of a specific object, activity, or situation, a phobia results in a compelling desire to avoid the perceived hazard. The patient recognizes that his fear is out of proportion to any actual danger, but he can’t control it or explain it away.
Type Of Phobias
Three types of phobias exist: 
  1. agoraphobia, the fear of being alone or of open space; 
  2. social, the fear of embarrassing oneself in public; and 
  3. specific, the fear of a single, specific object or situation, such as animals or heights.
About 7% of all Americans suffer from a phobic disorder. In fact, phobias are the most common psychiatric disorders in women and the second most common in men. More men than women experience social phobias, whereas agoraphobia and specific phobias are more common in women.
A social phobia typically begins in late childhood or early adolescence; a specific phobia usually begins in childhood. Most phobic patients have no family history of psychiatric illness, including phobias.
Agoraphobia and social phobia tend to be chronic; however, new treatments are improving the prognosis. A specific phobia usually resolves spontaneously as the child mature
A phobia develops when anxiety about an object or a situation compels the patient to avoid it. The precise cause of most phobias is unknown. Psychoanalytic theory holds that the phobia is actually repression and displacement of an internal conflict. Behavior theorists view phobia as a stimulus-response reflex, whereby the patient avoids a situation or object that causes anxiety.
Signs and symptoms
The phobic patient typically reports signs of severe anxiety when confronted with the feared object or situation. A patient with agoraphobia, for example, may complain of dizziness, a sensation of falling, a feeling of unreality (depersonalization), loss of bladder or bowel control, vomiting, or cardiac distress when he leaves home or crosses a bridge. Similarly, a patient who fears flying may report that he begins to sweat, his heart pounds, and he feels panicky and short of breath when he’s on an airplane.
A patient who routinely avoids the object of his phobia may report a loss of self-esteem and feelings of weakness, cowardice, or ineffectiveness. If he hasn’t mastered the phobia, he may also exhibit signs of mild depression, such as self-medicating with alcohol or drugs.
The effectiveness of treatment depends on the severity of the patient’s phobia. Because phobic behavior may never be completely cured, the goal of treatment is to help the patient function effectively.
Anxiolytics and antidepressants may help relieve symptoms in patients with agoraphobia.
Systematic desensitization, a behavioral therapy, may be more effective than drugs, especially if it includes encouragement, instruction, and suggestion.
In some cities, phobia clinics and group therapy are available. People who have recovered from phobias can often help other phobic patients.
