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.
