Anxiety disorders afflict approximately 40 million American adults each year, according to the National Institute of Mental Health. Anxiety disorders can manifest in many different forms, including panic disorder, generalized anxiety disorder, obsessive-compulsive disorder and post-traumatic stress disorder. Both biological and environmental factors affect the occurrence of anxiety disorders.


Serotonin, norepinephrine, and dopamine are chemicals that act as neurotransmitters or messengers in the brain.They send messages between different areas of the brain and are thought to influence one’s mood and anxiety level. One theory of panic disorder is that symptoms are caused by an imbalance of one or more of these chemicals.

Additional mental illness, daily life stressors and societal expectations have the potential to contribute to the development of generalized anxiety disorder when people have difficulty coping with them.

The focus of this approach is on genetics, neurotransmitters, neurophysiology, neuroanatomy etc. The approach argues that mental disorders are related to the physical structure and functioning of the brain.


ized Anxiety Disorder Questionnaire for DSM-IV (GADQ-IV), a reliable and validated measure of the diag-nostic criteria for generalized anxiety disorder (28). During data analysis, we used the dichotomous diagnostic approach for scoring the GADQ-IV (29) and then grouped participants according to whether their GADQ-IV responses suggested the pres-
