Causes of Generalized Anxiety Disorder (GAD)

Due to the complexities of Generalized Anxiety Disorder, it is difficult to pinpoint an exact cause. Research suggests that a number of factors, both environmental and genetic, may predispose a person to developing the symptoms of GAD.

Experts agree that a cause of Generalized Anxiety Disorder may be due to an imbalance of certain chemicals in the brain. Two neurotransmitters (chemical message carriers) called dopamine and serotonin, affect and regulate our moods and behavior. When these chemicals are imbalanced, they can cause Generalized Anxiety Disorder.

There also seems to be a correlation between Generalized Anxiety Disorder and other emotional disturbances, including depression, phobia disorder, and panic disorder. Generalized Anxiety Disorder is a risk factor for sleep disorders such as insomnia.

Research has shown a 20% risk for GAD in blood relatives of people with the disorder and a 10% risk among relatives of people with depression.
