Dysautonomia

Dysautonomia is a term for a group of diseases that include postural orthostatic tachycardia syndrome (POTS), multiple system atrophy, autonomic failure, and autonomic neuropathy. In these conditions the autonomic nervous system (ANS) does not work properly. Dysautonomia is most often a type of neuropathy affecting the nerves that carry information from the brain and spinal cord to the heart, bladder, intestines, sweat glands, pupils, and blood vessels; although it has many causes, not all of which classify as neuropathic.
