Anxiety

Psychological Factors

Psychologists have proposed a variety of models to explain anxiety. Austrian psychoanalyst Sigmund Freud suggested that anxiety results from internal, unconscious conflicts. He believed that a person’s mind represses wishes and fantasies about which the person feels uncomfortable. This repression, Freud believed, results in anxiety disorders, which he called neuroses.

More recently, behavioral researchers have challenged Freud’s model of anxiety. They believe one’s anxiety level relates to how much a person believes events can be predicted or controlled. Children who have little control over events, perhaps because of overprotective parents, may have little confidence in their ability to handle problems as adults. This lack of confidence can lead to increased anxiety.

Behavioral theorists also believe that children may learn anxiety from a role model, such as a parent. By observing their parent’s anxious response to difficult situations, the child may learn a similar anxious response. A child may also learn anxiety as a conditioned response. For example, an infant often startled by a loud noise while playing with a toy may become anxious just at the sight of the toy. Some experts suggest that people with a high level of anxiety misinterpret normal events as threatening. For instance, they may believe their rapid heartbeat indicates they are experiencing a panic attack when in reality it may be the result of exercise.

Social Factors

While some people may be biologically and psychologically predisposed to feel anxious, most anxiety is triggered by social factors. Many people feel anxious in response to stress, such as a divorce, starting a new job, or moving. Also, how a person expresses anxiety appears to be shaped by social factors. For example, many cultures accept the expression of anxiety and emotion in women, but expect more reserved emotional displays from men.

Treatment

Mental health professionals use a variety of methods to help people overcome anxiety disorders. These include psychoactive drugs and psychotherapy, particularly behavior therapy. Other techniques, such as exercise, hypnosis, meditation, and biofeedback, may also prove helpful.

A

Medications

Psychiatrists often prescribe benzodiazepines, a group of tranquilizing drugs, to reduce anxiety in people with high levels of anxiety. Benzodiazepines help to reduce anxiety by stimulating the GABA neurotransmitter system. Common benzodiazepines include alprazolam (Xanax), clonazepam (Klonopin), and diazepam (Valium). Two classes of antidepressant drugs—tricyclics and selective serotonin reuptake inhibitors (SSRIs)—also have proven effective in treating certain anxiety disorders.

Benzodiazepines can work quickly with few unpleasant side effects, but they can also be addictive. In addition, benzodiazepines can slow down or impair motor behavior or thinking and must be used with caution, particularly in elderly persons. SSRIs take longer to work than the benzodiazepines but are not addictive. Some people experience anxiety symptoms again when they stop taking the medications.

B

Psychotherapy

Therapists who attribute the cause of anxiety to unconscious, internal conflicts may use psychoanalysis to help people understand and resolve their conflicts. Other types of psychotherapy, such as cognitive-behavioral therapy, have proven effective in treating anxiety disorders. In cognitive-behavioral therapy, the therapist often educates the person about the nature of his or her particular anxiety disorder. Then, the therapist may help the person challenge irrational thoughts that lead to anxiety. For example, to treat a person with a snake phobia, a therapist might gradually expose the person to snakes, beginning with pictures of snakes and progressing to rubber snakes and real snakes. The patient can use relaxation techniques acquired in therapy to overcome the fear of snakes.

Research has shown psychotherapy to be as effective or more effective than medications in treating many anxiety disorders. Psychotherapy may also provide more lasting benefits than medications when patients discontinue treatment.
