Dysautonomia, autonomic failure, or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This may affect the functioning of the heart , bladder , intestines , sweat glands , pupils , and blood vessels.
characterized by Parkinsonism plus a more pronounced failure of the autonomic nervous system. [62] No modern equivalent – this terminology fell out of favour [63] and was not specified in the 2007 consensus paper. [38] The earlier consensus of 1998 [37] referred to MSA-A, "a" = autonomic dysfunction subtype but this subtype is no longer used.
Primary autonomic failure (also called primary dysautonomia) refers to a category of dysautonomias — conditions in which the autonomic nervous system does not function properly. In primary dysautonomias, the autonomic dysfunction occurs as a primary condition (as opposed to resulting from another disease). [ 1 ]
Bradbury and Eggleston originally described pure autonomic failure in 1925. [4] Patients usually present with orthostatic hypotension or syncope in midlife or later. In addition, genitourinary, thermoregulatory, and bowel dysfunction can be signs of autonomic failure. [5]
Autonomic neuropathy (AN or AAN) is a form of polyneuropathy that affects the non-voluntary, non-sensory nervous system (i.e., the autonomic nervous system), affecting mostly the internal organs such as the bladder muscles, the cardiovascular system, the digestive tract, and the genital organs. These nerves are not under a person's conscious ...
Orthostatic intolerance (OI) is the development of symptoms when standing upright that are relieved when reclining. [1] There are many types of orthostatic intolerance. OI can be a subcategory of dysautonomia, a disorder of the autonomic nervous system [2] occurring when an individual stands up. [3]
Autonomic dysreflexia (AD) is a life-threatening medical emergency characterized by hypertension and cardiac arrhythmias. [1] This condition is sometimes referred to as autonomic hyperreflexia. [ 2 ] Most cases of AD occur in individuals with spinal cord injuries. [ 3 ]
One commonly recognized autonomic dysfunction in diabetics is orthostatic hypotension, or becoming dizzy and possibly fainting when standing up due to a sudden drop in blood pressure. In the case of diabetic autonomic neuropathy, it is due to the failure of the heart and arteries to appropriately adjust heart rate and vascular tone to keep ...
