Agoraphobia is considered to be present when places or situations are being avoided. People with agoraphobia generally do not feel safe in public places. Their fear is worse when the place is crowded. Symptoms of agoraphobia include:

• Becoming housebound for prolonged periods of time
• Dependence on others
• Fear of being alone
• Fear of being in places where escape might be difficult
• Fear of losing control in a public place
• Feelings of detachment or estrangement from others
• Feelings of helplessness
• Feeling that the body is unreal
• Feeling that the environment is unreal
• Unusual temper or agitation

Signs and tests:

People who first experience panic sometimes fear they have a serious illness, or are even dying. Often, people will go to an emergency room or other urgent care center because they think they are having a heart attack.

A physical examination and psychological evaluation can help diagnose panic disorder. It is important to rule out any medical disorders, such as problems involving the heart, hormones, breathing, nervous system, and substance abuse. Which tests are done to rule out these conditions depends on the symptoms.
