Generalized anxiety disorder (or GAD) is characterized by excessive, exaggerated anxiety and worry about everyday life events with no obvious reasons for worry. People with symptoms of generalized anxiety disorder tend to always expect disaster and can't stop worrying about health, money, family, work, or school.It may involve naturally occurring brain chemicals (neurotransmitters), such as serotonin, dopamine and norepinephrine. It's likely that the condition has several causes that may include genetics, your life experiences and stress.The exact cause of GAD is not fully known, but a number of factors including genetics, brain chemistry, and environmental stresses appear to contribute to its development.
