Introduction

The disorder may be further categorized as generalized or specific social phobia:

• Generalized social phobia is the fear of being humiliated in front of other people during nearly all social situations. People with this subtype are the most socially impaired and also the most likely to seek treatment.
• Specific social phobia usually involves a phobic response to a specific event. Performance anxiety ("stage fright") is the most common specific social phobia and occurs when a person must perform in public. These patients usually feel comfortable in informal social situations.

Children with social anxiety develop symptoms in settings that include their peers, not just adults, and they may include tantrums, blushing, or not being able to speak to unfamiliar people. These children should be able to have normal social relationships with familiar people, however.

Specific Phobias. Specific phobias (formerly simple phobias) are an irrational fear of specific objects or situations. Specific phobias are among the most common medical disorders. Most cases are mild and not significant enough to require treatment.

The most common phobias are fear of animals (usually spiders, snakes, or mice), flying (pterygophobia), heights (acrophobia), water, injections, public transportation, confined spaces (claustrophobia), dentists (odontiatophobia), storms, tunnels, and bridges.

When confronting the object or situation, the phobic person experiences panicky feelings, sweating, avoidance behavior, difficulty breathing, and a rapid heartbeat. Most phobic adults are aware of the irrationality of their fear, and many endure intense anxiety rather than disclose their disorder.

Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) has been described as hiccups of the mind. OCD is time-consuming, distressing, and can disrupt normal functioning. Much research suggests that a critical feature in this disorder is an overinflated sense of responsibility, in which the patient's thoughts center around possible dangers and an urgent need to do something about it.

• Obsessions are recurrent or persistent mental images, thoughts, or ideas. The obsessive thoughts or images can range from mundane worries about whether one has locked a door to bizarre and frightening fantasies of behaving violently toward a loved one.
• Compulsive behaviors are repetitive, rigid, and self-prescribed routines that are intended to prevent the manifestation of an associated obsession. Such compulsive acts might include repetitive checking for locked doors or unlit stove burners or calls to loved ones at frequent intervals to be sure they are safe. Some people are compelled to wash their hands every few minutes or to spend inordinate amounts of time cleaning their surroundings in order to subdue the fear of contagion.
