According to the DSM-5, a diagnosis of GAD requires anxiety and worry that are associated with at least three of the following six symptoms, occurring on more days than not, for at least 6 months:
Restlessness or feeling keyed-up or on edge
Being easily fatigued
Difficulty concentrating or mind going blank
Irritability
Muscle tension
Sleep disturbance
For diagnosis, symptoms must result in the patient's impaired ability to function and cannot be attributed to a separate medical condition.
