Generalized Anxiety Disorder

People with Generalized Anxiety Disorder (GAD) find it difficult to control their worry. This inability to stop worrying or to relax, even in the absence of major life stresses, is one of the cardinal features of the disorder.

Individuals with GAD also often experience a number of associated symptoms:

  • Restlessness or feeling keyed up or on edge
  • Being easily fatigued
  • Difficulty concentrating
  • Irritability
  • Muscle tension
  • Sleep disturbance

The anxiety and worry is considered a disorder if it is severe enough to cause an individual significant distress or interferes with social or occupational functioning. Adults with GAD often worry excessively about everyday, routine life circumstances such as possible job responsibilities, finances, or the health of family members. A number of effective treatments are available for GAD, such as anti-anxiety medication or cognitive-behavioral therapy (which reduces worry through changes in thinking and behavior patterns).
