Autonomic Disorders

Abstract

A practical but arbitrary classification of autonomic disorders is used at Mayo Clinic. Presented in a modified and abbreviated form in this chapter, that classification serves to organize and provide an overview of autonomic disorders. It is organized by anatomical systems and levels, although some syndromes and disorders do not fit neatly into this organization and therefore are assigned their own category. This classification quickly shows how abundant and interspersed autonomic dysfunction is among various categories of neurologic disease. Therefore, the role of this chapter is not to describe every disorder that can be associated with autonomic dysfunction. Rather, the chapter focuses on disorders with autonomic dysfunction as a predominant or important feature and thereby covers what are generally referred to as autonomic disorders.
