Autonomic disorders in multiple sclerosis.

Multiple sclerosis is an inflammatory disease leading to disseminated lesions of the central nervous system resulting in both somatomotor and autonomic disturbances. These involve the central centers of the autonomic nervous system, as well as the automatic control and pathway systems. All autonomic functions may be disordered individually or in combined form. There is no other disease with a clinical picture so multifaceted. Besides cardiovascular dysfunctions disorders of bladder and rectum have become apparent. Somatomotor and autonomic disturbances occur with similar frequency; however the focused exam often heavily favors somatomotor symptoms. Autonomic disturbances should primarily be taken into account on history taking and clinical examination. Individual diagnosis and treatment is a secondary feature. Impairments of the autonomic nervous systems in multiple sclerosis are frequently overlooked.
