Generalized anxiety disorder (GAD) is associated with substantial distress and disability
GAD is often associated with other medical and psychiatric disorders

Generalized anxiety disorder (GAD) is relatively common, with lifetime prevalence rates of 4-7%. It is a disorder of chronic uncontrollable worry, compounded by physiological symptoms such as disturbed sleep, muscle tension, and difficulty concentrating.
