Panic disorder is an anxiety disorder characterized by the spontaneous and unexpected occurrence of panic attacks. Panic attacks can occur at any time, even during sleep. An attack usually peaks within 10 minutes, but some symptoms may last much longer.

The DSM-IV-TR delineates the following potential symptom manifestations of a panic attack:

• Palpitations, pounding heart, or accelerated heart rate
• Sweating
• Trembling or shaking
• Sense of shortness of breath or smothering
• Feeling of choking
• Chest pain or discomfort
• Nausea or abdominal distress
• Feeling dizzy, unsteady, lightheaded, or faint
• Derealization or depersonalization (feeling detached from oneself)
• Fear of losing control or going crazy
• Fear of dying
• Numbness or tingling sensations
• Chills or hot flashes

Panic disorder can lead to a significant hindrance in lifestyle. Many people with agoraphobia are unable to travel alone or be in crowds or malls or on public transportation. Individuals with panic disorder also may face problems with employment and depression.
After all it is a matter of satisfaction that Panic disorder is a real illness that can be successfully treated.
