What is generalized anxiety disorder?

Persistent Worry: Generalized anxiety disorder is characterized by a chronic, persistent tendency to worry about many different aspects of life. It may also be associated with physical symptoms related to stress. It is different from panic disorder, which has to do with severe episodes of intense, overwhelming fear. However, it is not unusual for people to struggle with both types of anxiety.

GAD: Or generalized anxiety disorder is a persistent pattern of anxiety/worry about a number of things for at least 6 months. It involves feeling restless or keyed up, easy fatiguability, trouble concentrating, irritability, muscle tension and/or sleep distturbance. These anxieties cause significant distress or impairment in functioning.
