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.
The signs and symptoms of autonomic neuropathy include the following: [citation needed] Urinary bladder conditions: urinary incontinence or urinary retention which happens due to the uncoordinated contraction of the bladder. Neurogenic bladder is a broad term describing this dysfunction. [1]
Signs and symptoms of familial dysautonomia usually commence during infancy and worsen with age, and may include gastrointestinal dysmotility (including erratic gastric emptying, gastroesophageal reflux, abnormal esophageal peristalsis, oropharyngeal incoordination), [3] dysphagia (as poor suckling in infancy) and frequent choking/gagging, recurrent vomiting, poor weight gain [6] /growth, [7 ...
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.
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 ...

In addition, other symptoms include cluster headaches, tearing of the eyes, nasal discharge, abnormal contraction ...
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 ...
The prominent sensory abnormalities and foot ulcerations are the only signs to separate HSAN I from HMSN. [2] [38] [39] HSAN II can be differentiated from HSAN I as it is inherited as an autosomal recessive trait, it has earlier disease onset, the sensory loss is diffused to the whole body, and it has less or no motor symptoms. HSAN III-V can ...
