Generalized anxiety disorder (GAD) is chronic, exaggerated worry and tension that lasts over 6 months or more. Worry is normal but the type with anxiety it happens without known cause or is much more severe than normal. People with this disorder usually expect the worst. They worry excessively about money, health, family, or work, even when there are no signs of trouble. They are unable to relax and often suffer from sleep problems and concentration problems. Many people with GAD also have physical symptoms. This may include fatigue, trembling, muscle tension, headaches, irritability, or hot flashes.
