Generalized Anxiety Disorder (GAD) is one of the most commonly diagnosed mental disorders. It is characterized by excessive and uncontrollable worry about various activities and situations. This worry can lead to impaired social and occupational functioning. GAD has been linked to both biological factors like genetics and heredity as well as environmental influences. It can be difficult to diagnose due to its interwoven origins and potential to co-occur with other disorders. Treatment typically involves medication and cognitive behavioral therapy. Primary care professionals need training to properly screen for and diagnose GAD to prevent misdiagnosis.
