n. (context medicine English) Any of a range of dysfunctions of the autonomic nervous system
Wikipedia
Dysautonomia (or ' autonomic neuropathy') is a term for various conditions in which the autonomic nervous system (ANS) does not work correctly. Dysautonomia is 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.
The diagnosis is achieved through functional testing of the autonomic nervous system, focusing on the organ system affected. Investigations may be performed to identify underlying disease processes that may have led to the autonomic neuropathy that is causing the dysautonomia. Symptomatic treatment is available for many symptoms associated with autonomic neuropathy, and some disease processes can be treated directly.
