Under normal circumstances, anxiety is a biological warning system that enables a person to anticipate and avoid harm and failure. Recent advances in the physiology and pharmacology of the central nervous system, and technical advances (imaging in particular), have opened new avenues toward a better understanding of the biology of anxiety.

The human body is an amazing and very complex organism. The intricacies of our bodies, especially our brains, are presumed to be involved in the origins and maintenance of anxiety disorders. As mentioned, biological factors (or vulnerabilities) usually have to be in place for an anxiety disorder to manifest.
Many factors are involved in the etiology of anxiety disorders. Biological causes, genetics, psychological issues and traumatic events, or a combination of any or all of these can contribute to an anxiety disorder.

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.
Barlow has defined three interacting sets of vulnerability factors for the development of human anxiety disorders in humans: (i) a generalized biological vulnerability, mainly of genetic origin; (ii) a generalized psychological vulnerability, resulting in particular from early life experiences; and (iii) a specific psychological vulnerability ...
There is no singular cause of generalized anxiety disorder that has been identified. Evidence has shown that multiple factors are usually at play, influencing the development of GAD. Some of the common factors include things like genetic predisposition, brain chemistry, family background, social influence, and life experiences.
This article collection aims to focus on all areas relevant to the mood and anxiety disorders at the level of their underlying mechanisms, including but not limited to: pathophysiology, predictive risk markers, treatment predictors, individual differences and developmental trajectories of mood and anxiety disorders.
