autonomic nervous system disease

Last reviewed 01/2018

Autonomic failure involves both the parasympathetic and sympathetic systems, however it is failure of the sympathetic system which produces most symptoms.

Classically the patient is a middle-aged male who complains of impotence, inability to sweat and postural blackouts when standing up.

Commonly autonomic failure is associated with systemic disease, neurodegenerative disorders or drugs effects.
