Dysautonomia, autonomic failure, or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This condition may affect the functioning of the heart , bladder , intestines , sweat glands , pupils , and blood vessels.
Symptoms include upper gastrointestinal tract dysfunction such as delayed gastric emptying or lower gastrointestinal dysfunction, such as constipation and prolonged stool transit time. [ 15 ] Urinary retention , waking at night to urinate , increased urinary frequency and urgency, and over- or underactive bladder are common in people with ...
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 ...
Pure autonomic failure (PAF) is an uncommon, sporadic neurodegenerative condition marked by a steadily declining autonomic regulation. [3] Bradbury and Eggleston originally described pure autonomic failure in 1925. [4] Patients usually present with orthostatic hypotension or syncope in midlife or later.
[4] [6] Associated features include parkinsonism, cognitive decline, and dysfunction of the autonomic nervous system. [4] [6] FXTAS is found in Fragile X "premutation" carriers, which is defined as a trinucleotide repeat expansion of 55-200 CGG repeats in the Fragile X mental retardation-1 gene.
In primary dysautonomias, the autonomic dysfunction occurs as a primary condition (as opposed to resulting from another disease). [1] Autonomic failure is categorized as "primary" when believed to result from a chronic condition characterized by degeneration of the autonomic nervous system, or where autonomic failure is the predominant symptom ...
Sudomotor dysfunction is one of the most common and earliest neurophysiological manifestations of small fiber neuropathies. [3] In some instances, the small fibers of the autonomic nervous system can be affected, leading to urinary or bowel problems, episodes of rapid heartbeat (palpitations), dry eyes or mouth, or abnormal sweating.
Hereditary sensory and autonomic neuropathy type 6 (HSAN6), also known as familial dysautonomia with contractures, [5] is a severe autosomal recessive disorder characterized by neonatal hypotonia, respiratory and feeding difficulties, lack of psychomotor development, and autonomic abnormalities including labile cardiovascular function, lack of ...
