People with generalized anxiety disorder (GAD) experience excessive anxiety and worry, often about health, family, money, or work. This worrying goes on every day, possibly all day. It disrupts social activities and interferes with work, school, or family.
GAD is diagnosed in adults when they experience at least three of the symptoms below on more days than not for at least six months; only one symptom is required in children.
Symptoms of GAD include the following:
- restlessness or feeling keyed up or on edge
- being easily fatigued
- difficulty concentrating or mind going blank
- muscle tension
- sleep disturbance (difficulty falling or staying asleep, or restless, unsatisfying sleep)
