What is Dysautonomia?
Dysautonomia refers to a disorder of autonomic nervous system (ANS) function. Most physicians view dysautonomia in terms of failure of the sympathetic or parasympathetic components of the ANS, but dysautonomia involving excessive ANS activities can also occur. Dysautonomia can be local, as in reflex sympathetic dystrophy, or generalized, as in pure autonomic failure. It can be acute and reversible, as in Guillain-Barre syndrome, or chronic and progressive. Several common conditions such as diabetes and alcoholism can include dysautonomia. Dysautonomia can also occur as a primary condition or in association with degenerative neurological diseases such as Parkinson's disease. Other diseases with generalized, primary dysautonomia include multiple system atrophy and familial dysautonomia. Hallmarks of generalized dysautonomia because of sympathetic failure are impotence (in men) and a fall in blood pressure during standing (orthostatic hypotension). Excessive sympathetic activity can present as hypertension or a rapid pulse rate.
Is there any treatment?
There is no cure for dysautonomia. Secondary forms may improve with treatment of the underlying disease. In A lot of cases treatment of primary dysautonomia is symptomatic and supportive. Measures to combat orthostatic hypotension include elevation of the head of the bed, frequent small meals, a high-salt diet, and drugs such as fludrocortisone, midodrine, and ephedrine.
What is the prognosis?
The outlook for patients with dysautonomia depends on the particular diagnostic category. Patients with chronic, progressive, generalized dysautonomia in the setting of central nervous system degeneration have a usually poor long-term prognosis. Death can occur from pneumonia, acute respiratory failure, or sudden cardiopulmonary arrest in such patients.
