Anxiety and endocrine disease.

It is our goal in this article to review the literature and define those endocrinological diseases that often include anxiety states as part of their initial presentation or as a characteristic symptom seen during their course. Understanding the mechanism by which anxiety develops as a routine part of these neuroendocrinological disorders may help us understand the organic basis of anxiety disorders. Research using new neurochemical, neuroanatomical, and brain imaging techniques may further define the structural and physiological underpinnings of the anxiety disorders.
