Panic Disorder: People with panic disorder have panic attacks with feelings of terror that strike suddenly and repeatedly with no warning. During the attacks, individuals may feel like they can't breathe, have lost control, are having a heart attack or even that they are dying. Physical symptoms may include chest pain, dizziness, nausea, sweating, tingling or numbness, and a racing heartbeat. Some people will have one isolated attack, while others will develop a long term panic disorder; either way, there is often high anxiety between attacks because there is no way of knowing when the next one will occur. Panic disorders often begin early in adulthood. Many people with panic disorder also suffer from agoraphobia (abnormal fear of open or public places.). See more on Panic Attacks.
A panic attack is a sudden rush of fear and anxiety that seems to come out of nowhere and causes both physical and psychological symptoms. The level of fear experienced is unrealistic and completely out of proportion to the events or circumstances that trigger a panic attack. Anyone can have a single panic attack, but frequent and ongoing episodes may be a sign of a panic or anxiety disorder that requires treatment.
Although the exact causes of panic attacks and panic disorder are unclear, the tendency to have panic attacks runs in families. There also appears to be a connection with major life transitions such as graduating from college and entering the workplace, getting married, or having a baby. Severe stress, such as the death of a loved one, divorce, or job loss can also trigger panic attacks.
Occasional anxiety is an expected part of life. You might feel anxious when faced with a problem at work, before taking a test, or before making an important decision. But anxiety disorders involve more than temporary worry or fear. For a person with an anxiety disorder, the anxiety does not go away and can get worse over time. The symptoms can interfere with daily activities such as job performance, school work, and relationships.
