What It Is
Generalized Anxiety Disorder: Generalized anxiety disorder (GAD) is an anxiety disorder characterized by excessive, uncontrollable, and often irrational worry about events or activities. Worry often interferes with daily functioning. Individuals with GAD are often, but not necessarily, overly concerned about everyday matters such as health, finances, death, family, relationship concerns, or work difficulties. Symptoms may include excessive worry, restlessness, trouble sleeping, exhaustion, irritability, sweating, and trembling.
Why It Happens
Generalized Anxiety Disorder arises due to factors affecting the Mental Health & Behavioral System. Mental health conditions involve complex interactions between brain chemistry, neural circuitry, psychological experiences, and social environment. While individual cases vary, a combination of genetic susceptibility, lifestyle factors, and environmental exposures typically contribute to the development of Generalized Anxiety Disorder.
