What is the minimum duration of excessive worrying to diagnose Generalized Anxiety Disorder (GAD)?

To diagnose Generalized Anxiety Disorder (GAD), the minimum duration of excessive worrying must be at least 6 months. This criterion is part of the diagnostic guidelines set out in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), which is commonly used by mental health professionals. The duration is important as it helps to distinguish between normal fluctuations in anxiety and a consistent pattern of excessive worry that interferes with daily functioning.

In GAD, the anxiety and worry are difficult to control and are accompanied by symptoms such as restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbance. By setting the minimum duration to 6 months, the guidelines ensure that the diagnosis reflects a chronic condition rather than a temporary response to stressors or situational anxiety.
