Every human feels anxiety on occasion; it is a part of life. All of us know what it is like to feel worry, nervousness, fear, and concern. We feel nervous when we have to give a speech, go for a job interview, or walk into our bosss office for the annual performance appraisal. We know its normal to feel a surge of fear when we unexpectedly see a photo of a snake or look down from the top of a tall building. Most of us manage these kinds of anxious feelings fairly well and are able to carry on with our lives without much difficulty. These feelings dont disrupt our lives.

But millions of people (an estimated 15% of the population) suffer from devastating and constant anxiety that severely affects their lives, sometimes resulting in living in highly restricted ways. These people experience panic attacks, phobias, extreme shyness, obsessive thoughts, and compulsive behaviors. The feeling of anxiety is a constant and dominating force that disrupts their lives. Some become prisoners in their own homes, unable to leave to work, drive, or visit the grocery store. For these people, anxiety is much more than just an occasional wave of apprehension.

Types of Anxiety Disorders

An anxiety disorder affects a persons behavior, thoughts, feelings, and physical sensations. The most common anxiety disorders include the following:

Social anxiety or social phobia is a fear of being around other people. People who suffer from this disorder always feel self-conscious around others. They have the feeling that everyone is watching them and staring at them, being critical in some way. Because the anxiety is so painful, they learn to stay away from social situations and avoid other people. Some eventually need to be alone at all times, in a room with the door closed. The feeling is pervasive and constant and even happens with people they know.

People who have social anxiety know that their thoughts and fears are not rational. They are aware that others are not actually judging or evaluating them at every moment. But this knowledge does not make the feelings disappear.

Panic disorder is a condition where a person has panic attacks without warning. According to the National Institutes of Mental Health, about 5% of the adult American population suffers from panic attacks. Some experts say that this number is actually higher, since many people experience panic attacks but never receive treatment.

Common symptoms of panic include:

Racing or pounding heart
Trembling
Sweaty palms
Feelings of terror
Chest pains or heaviness in the chest
Dizziness and lightheadedness
Fear of dying
Fear of going crazy
Fear of losing control
Feeling unable to catch ones breath
Tingling in the hands, feet, legs, or arms

A panic attack typically lasts several minutes and is extremely upsetting and frightening. In some cases, panic attacks last longer than a few minutes or strike several times in a short time period.

A panic attack is often followed by feelings of depression and helplessness. Most people who have experienced panic say that the greatest fear is that the panic attack will happen again.

Many times, the person who has a panic attack doesnt know what caused it. It seems to have come out of the blue. At other times, people report that they were feeling extreme stress or had encountered difficult times and werent surprised that they had a panic attack.

Generalized anxiety disorder is quite common, affecting an estimated 3 to 4% of the population. This disorder fills a persons life with worry, anxiety, and fear. People who have this disorder are always thinking and dwelling on the what ifs of every situation. It feels like there is no way out of the vicious cycle of anxiety and worry. The person often becomes depressed about life and their inability to stop worrying.

People who have generalized anxiety usually do not avoid situations, and they dont generally have panic attacks. They can become incapacitated by an inability to shut the mind off, and are overcome with feelings of worry, dread, fatigue, and a loss of interest in life. The person usually realizes these feelings are irrational, but the feelings are also very real. The persons mood can change from day to day, or even hour to hour. Feelings of anxiety and mood swings become a pattern that severely disrupts the quality of life.

People with generalized anxiety disorder often have physical symptoms including headaches, irritability, frustration, trembling, inability to concentrate, and sleep disturbances. They may also have symptoms of social phobia and panic disorder.

Other types of anxiety disorders include:

Phobia, fearing a specific object or situation.

Obsessive-compulsive disorder (OCD), a system of ritualized behaviors or obsessions that are driven by anxious thoughts.

Post-traumatic stress disorder (PTSD), severe anxiety that is triggered by memories of a past traumatic experience.

Agoraphobia, disabling fear that prevents one from leaving home or another safe place.

Treatment Options

Most people who suffer from anxiety disorders begin to feel better when they receive the proper treatment. It can be difficult to identify the correct treatment, however, because each persons anxiety is caused by a unique set of factors. It can be frustrating for the client when treatment is not immediately successful or takes longer than hoped for. Some clients feel better after a few weeks or months of treatment, while others may need a year or more. If a person has an anxiety disorder in combination with another disorder (such as alcoholism and depression), treatment is more complicated and takes longer.

While a treatment plan must be specifically designed for each individual, there are a number of standard approaches. Mental health professionals who specialize in treating anxiety most often use a combination of the following treatments. There is no single correct approach.

Cognitive Therapy

The client learns how to identify and change unproductive thought patterns by observing his or her feelings and learning to separate realistic from unrealistic thoughts.

Behavior Therapy

This treatment helps the client alter and control unwanted behavior. Systematic desensitization, a type of behavior therapy, is often used to help people with phobias and OCD. The client is exposed to anxiety-producing stimuli one small step at a time, gradually increasing his or her tolerance to situations that have produced disabling anxiety.

Relaxation Training

Many people with anxiety disorders benefit from self-hypnosis, guided visualization, and biofeedback. Relaxation training is often part of psychotherapy.

Medication

Antidepressant and antianxiety medications can help restore chemical imbalances that cause symptoms of anxiety. This is an effective treatment for many people, especially in combination with psychotherapy.

The treatment for an anxiety disorder depends on the severity and length of the problem. The clients willingness to actively participate in treatment is also an important factor. When a person with panic is motivated to try new behaviors and practice new skills and techniques, he or she can learn to change the way the brain responds to familiar thoughts and feelings that have previously caused anxiety.
