Generalized Anxiety Disorder | Causes & Risk Factors


What causes anxiety disorders?

Suppose the fire alarm goes off in your home. You race around frantically to find the fire. Instead, you find that there is no fire--the alarm just isn't working properly.

It's the same with anxiety disorders. Your body mistakenly triggers your alarm system when there is no danger. This may be due to a chemical imbalance in your body. It may also be related to an unconscious memory, to a side effect of a medicine or to an illness.
