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 and relationships.

There are several types of anxiety disorders, including generalized anxiety disorder, panic disorder, post-traumatic stress disorder (PTSD),  various phobia-related disorders.


Individuals with generalized anxiety disorder (GAD) go through the day filled with exaggerated worry and tension, even though there is little or nothing to provoke it.  They anticipate disaster and are overly concerned about health issues, money, family problems or difficulties at work.  Sometimes just the thought of getting through the day produces anxiety.

Generalized anxiety disorder is diagnosed when a person worries excessively about a variety of everyday problems for at least 6 months.  People with GAD can’t seem to get rid of their concerns, even though they usually realize that their anxiety is more intense than the situation warrants.  They can’t relax, startle easily, and have difficulty concentrating.  Often they have trouble falling asleep or staying asleep.  Physical symptoms that often accompany the anxiety include fatigue, headaches, muscle tension, muscle aches, difficulty swallowing, trembling, twitching, irritability, sweating, nausea, lightheadedness, having to go to the bathroom frequently, feeling out of breath and hot flashes.

When their anxiety level is mild, people with generalized anxiety disorder can function socially and hold down a job.   Although they don’t avoid certain situations as a result of their disorder, people with GAD can have difficulty carrying out the simplest daily activities if their anxiety is severe.

GAD affects about 6.8 million American adults, including twice as many women as men.  The disorder develops gradually and can begin at any point in the life cycle, although the years of highest risk are between childhood and middle age.  There is evidence that genes play a modest role in GAD.

Other anxiety disorders, depression, or substance abuse often accompany GAD, which rarely occurs alone.  GAD is commonly treated with medication or cognitive-behavioral therapy, but co-occurring conditions must also be treated using the appropriate therapies.
