What are the key symptoms of general anxiety disorder (GAD)?

The key symptoms of generalized anxiety disorder (GAD) primarily center around a persistent state of excessive worry and anxiety that is difficult to control. Individuals with GAD often experience a range of symptoms, including excessive worry about various aspects of life, constant feelings of restlessness or being on edge, chronic fatigue, difficulty concentrating, and increased irritability. These symptoms align with the core features of GAD as outlined in mental health diagnostic criteria.

Excessive worry is a hallmark of GAD and can manifest in concerns about health, work, and social interactions, often to a degree that interferes with daily functioning. Additionally, the restlessness and fatigue can stem from the mental and physical toll of prolonged anxiety, making it challenging for individuals to relax or focus on tasks. Difficulty concentrating often occurs as the mind is preoccupied with anxious thoughts, and irritability can develop as a response to the stress of constant worry.
