Anxiety Disorders Affect an Estimated 470 Million People Worldwide

Anxiety disorders involve persistent or excessive fear, worry or anxiety that can interfere with everyday activities. They include conditions such as generalized anxiety disorder, panic disorder and certain phobia-related disorders. Symptoms may include restlessness, difficulty concentrating, sleep disturbances, muscle tension, rapid heartbeat and persistent worry. Some people also experience physical symptoms that can be mistaken for other medical problems. Anxiety can affect education, employment, relationships and physical wellbeing. When symptoms persist, individuals may avoid activities or situations, which can further affect their quality of life. Evidence-based treatments include psychological therapies such as cognitive behavioural therapy and, when appropriate, medication prescribed by a qualified clinician. Relaxation techniques and regular physical activity may complement treatment, but they do not replace professional care when symptoms are severe. The global estimate emphasizes the need to reduce stigma and improve access to assessment and effective treatment. The exact prevalence depends on the population studied and the definitions used.
