How common is generalized anxiety disorder?

Generalized anxiety disorder (GAD) is a common mental disorder that affects millions of people worldwide. According to the World Health Organization (WHO), GAD affects approximately 2-5% of the global population. It is more prevalent in women than in men, and the onset typically occurs during adolescence or early adulthood.

In the United States, GAD is estimated to affect approximately 6.8% of adults, making it one of the most prevalent mental disorders. The lifetime prevalence of GAD in the U.S. is about 18%, meaning that nearly 1 in 5 adults will experience symptoms of GAD at some point in their lives.

GAD is characterized by excessive, uncontrollable worry about a variety of topics, including work, school, relationships, health, finances, and the future. People with GAD may also experience physical symptoms such as muscle tension, fatigue, irritability, sleep disturbances, and difficulty concentrating.

GAD can significantly interfere with a person's daily life, impairing their ability to function effectively in various areas, including work, school, and relationships. It often co-occurs with other mental health conditions, such as depression, substance use disorders, and panic disorder.

Treatment for GAD typically involves a combination of therapy, medication, and self-care strategies. Cognitive-behavioral therapy (CBT) is a widely used therapeutic approach that helps individuals identify and change negative thinking patterns and behaviors that contribute to their anxiety. Medication, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), may also be prescribed to manage anxiety symptoms.
