Anxiety Disorders: Panic Disorder, Phobias, PTSD ...

What are anxiety disorders?

Anxiety disorders range from feelings of uneasiness to immobilizing bouts of terror. This fact sheet briefly describes the different types of anxiety disorders. This fact sheet is not exhaustive, nor does it include the full range of symptoms and treatments. Keep in mind that new research can yield rapid and dramatic changes in our understanding of and approaches to mental disorders. If you believe you or a loved one has an anxiety disorder, seek competent, professional advice or another form of support.

Generalized Anxiety Disorder

Most people experience anxiety at some point in their lives and some nervousness in anticipation of a real situation. However if a person cannot shake unwarranted worries, or if the feelings are jarring to the point of avoiding everyday activities, he or she most likely has an anxiety disorder.

Symptoms: Chronic, exaggerated worry, tension, and irritability that appear to have no cause or are more intense than the situation warrants. Physical signs, such as restlessness, trouble falling or staying asleep, headaches, trembling, twitching, muscle tension, or sweating, often accompany these psychological symptoms.

Formal diagnosis: When someone spends at least six months worried excessively about everyday problems. However, incapacitating or troublesome symptoms warranting treatment may exist for shorter periods of time.

Treatment: Anxiety is among the most common, most treatable mental disorders. Effective treatments include cognitive behavioral therapy, relaxation techniques, and biofeedback to control muscle tension. Medication, most commonly anti-anxiety drugs, such as benzodiazepine and its derivatives, also may be required in some cases. Some commonly prescribed anti-anxiety medications are diazepam, alprazolam, and lorazepam. The non-benzodiazepine anti-anxiety medication buspirone can be helpful for some individuals.

Panic Disorder

People with panic disorder experience white-knuckled, heart-pounding terror that strikes suddenly and without warning. Since they cannot predict when a panic attack will seize them, many people live in persistent worry that another one could overcome them at any moment.

Symptoms: Pounding heart, chest pains, lightheadedness or dizziness, nausea, shortness of breath, shaking or trembling, choking, fear of dying, sweating, feelings of unreality, numbness or tingling, hot flashes or chills, and a feeling of going out of control or going crazy.

Formal Diagnosis: Either four attacks within four weeks or one or more attacks followed by at least a month of persistent fear of having another attack. A minimum of four of the symptoms listed above developed during at least one of the attacks. Most panic attacks last only a few minutes, but they occasionally go on for ten minutes, and, in rare cases, have been known to last for as long as an hour. They can occur at any time, even during sleep.

Treatment: Cognitive behavioral therapy and medications such as high-potency anti-anxiety drugs like alprazolam. Several classes of antidepressants (such as paroxetine, one of the newer selective serotonin reuptake inhibitors) and the older tricyclics and monoamine oxidase inhibitors (MAO inhibitors) are considered "gold standards" for treating panic disorder. Sometimes a combination of therapy and medication is the most effective approach to helping people manage their symptoms. Proper treatment helps 70 to 90 percent of people with panic disorder, usually within six to eight weeks.
