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. Dysautonomia has many causes, not all of which may be classified as neuropathic. [5]
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 ]
Each of these patients felt much worse during the heat of summer." [12] [13] Further research identified multiple causes for these syndromic findings, now grouped as primary autonomic disorders (also called primary dysautonomia), including Pure Autonomic Failure, Multiple System Atrophy, and Parkinson's. The primary differentiating ...
Falls—caused by many factors including parkinsonism, dysautonomia, and frailness—increase morbidity and mortality. [56] Failure to thrive [8] and aspiration pneumonia, a complication of dysphagia (difficulty swallowing) that results from dysautonomia, commonly cause death among people with the Lewy body dementias. [80]
Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system.Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis, and hyperthermia.

The voltage (intensity) is started at 0, progressively raised to a threshold of patient discomfort, and then is decreased to a level that the patient finds comfortable. As the patient's tolerance increases, the voltage can be gradually increased to 250 to 350 Volts. Each treatment session usually lasts between 15 and 60 minutes.
Orthostatic hypotension and significant gastrointestinal symptoms are also hallmarks of paraneoplastic dysautonomia. Paraneoplastic dysautonomia has been linked to thymoma, small-cell lung carcinoma, and, less frequently, breast cancer or lymphoma. At the time of the development of autonomic symptoms, the underlying malignancy is usually unknown.
Familial dysautonomia (FD), also known as Riley–Day syndrome, is a rare, [2] progressive, [3] recessive genetic disorder of the autonomic nervous system [2] that affects the development and survival of sensory, sympathetic, and some parasympathetic neurons in the autonomic and sensory nervous system.
