[Clinical significance of sudomotor evaluation for neurological diagnosis]

Human sweating is functionally classified into thermoregulatory, emotional, and gustatory sweating. Several central and peripheral nervous structures are involved in the sudomotor systems. Therefore, an anatomical understanding of the sudomotor systems and clinical evaluation of its function are useful for regional neurological diagnose. In addition, some neurological diseases may present characteristic abnormalities of sweating. This systematic review summarizes the anatomy, physiology, and symptomatology of sweating as well as the clinical characteristics of abnormal sweating in neurological disorders.
