A panic attack is an anxiety attack at its worst. Panic attacks are marked by extreme physical, emotional and mental panic or terror, usually focused around an abnormal fear. Symptoms of a panic attack are often compared to the "fight or flight" sensation of the entire body being on edge as if danger is at hand.

A panic attack may start as generalized anxiety, a feeling of unease that builds into extreme physical symptoms, or it may strike out of the blue. You may even awake from a sound sleep in the midst of a panic attack. Most panic attacks last anywhere from 20 minutes to an hour and gradually subside.

Often panic attacks will strike when one is engaged in a mundane activity like driving or shopping. Over a period of time these activities might then become feared and avoided, resulting in limitations or phobias. If one tries to engage in these feared activities, worrying about a panic attack can bring one on. Thus panic disorders like agoraphobia can develop.

The physical symptoms of a panic attack might include any or all of the following:

• Heart palpitations
• Increased blood pressure
• Hot flashes or chills
• Shortness of breath
• Dizziness or spaciness
• Nausea
• Sweating
• Feeling faint
• Facial ticks
• Trembling
• Chest pains
• Tingling in muscles
• Fear of losing control and humiliating yourself
• Fear of a heart attack
• Fear of losing your mind
• Fear of dying

As physical symptoms build, they trigger more panic and fear that feeds the panic attack. The body releases chemicals into the system like adrenaline, sodium lactate and cortisol which are stimulants designed to help put the person in a flee or fight state. At this point the person having the panic attack becomes more worried about their physical symptoms than whatever it was that triggered the attack. They often start asking themselves things like, "What's wrong with me? Am I having a heart attack? Am I going to faint? Do I have a brain tumor?" People who don't know they are experiencing a panic attack will often go to the hospital truly believing they are dying.

Panic attacks and anxiety disorders are thought to be genetic and biochemical, and are found in children as well as adults of all ages. Many people who experience panic attacks do not recognize them for what they are and are afraid or embarrassed to seek help. Panic attacks are not harmful in and of themselves, and do not lead to heart attacks, loss of control, mental illness or death. However, they do impact quality of life and can be very debilitating to those who suffer from them, severely limiting their activities and enjoyment of life.

Prolonged anxiety and panic attacks can lead to reduced self-esteem and self worth. This general lack of well-being can affect levels of certain neurotransmitters in the brain, like serotonin, which moderates mood. With lower levels of serotonin, depression and negative thinking can set in. For this reason depression is often found alongside anxiety disorders.

Panic attacks and generalized anxiety are very common and are treatable a variety of ways. Antidepressants are often prescribed, and cognitive behavioral programs that offer tools for overcoming limitations and understanding panic attacks are also effective, like that offered by the renowned Midwest Center for Stress and Anxiety. Diet plays its own part in curbing panic attacks and anxiety, especially elimination or marginalizing of sugar and caffeine.

It is estimated that 3-6 million Americans suffer from panic disorder every year and about one third of the population will experience a panic attack at some point in their lives. If you have been experiencing panic attacks, generalized anxiety or depression, talk to your physician about the options that are best for you.
