Autoimmune autonomic ganglionopathy is a type of immune-mediated autonomic failure that is associated with antibodies against the ganglionic nicotinic acetylcholine receptor present in sympathetic, parasympathetic, and enteric ganglia. Typical symptoms include gastrointestinal dysmotility, orthostatic hypotension, and tonic pupils. [1]
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.
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 ...
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 ...
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 .
As the disease progresses, neuronal dysfunction correlates closely with the development of blood vessel abnormalities, such as capillary basement membrane thickening and endothelial hyperplasia, which contribute to diminished oxygen tension and hypoxia. Neuronal ischemia is a well-established characteristic of diabetic neuropathy.
ME/CFS is associated with changes in several areas, including the nervous and immune systems, as well as disturbances in energy metabolism. [11] [14] Neurological differences include autonomic nervous system dysfunction and a change in brain structure and metabolism. [44]
Cerebellar dysfunction - difficulty coordinating movement and balance [15] Autonomic nervous system dysfunction - impaired automatic body functions, including one, some, or all of the following: [16] postural or orthostatic hypotension, resulting in dizziness or fainting upon standing up [17] urinary incontinence or urinary retention [18] [19 ...
