title: [Pure primitive dysautonomia or Bradbury-Eggleston syndrome. Report of 3 cases].
abstract: The primary autonomic failure (Bradbury-Eggleston syndrome) is rare. We report three cases (two females and one male) who are 55 year old with orthostatic hypotension, tachycardia, and other signs of dysautonomia. They hadn't a pyramidal, extrapyramidal or cerebellar syndromes. The other causes of postural hypotension are excluded. The autonomic dysfunction was confirmed by autonomic reflex tests and by evaluating of cardiac reflex function; these included heart rate responses to deep breathing and to the valsalva maneuver. Hypotension occurs in a variety of clinical setting; ascertainment of the cause is by non means easy. Primary autonomic failure remains a diagnostic category based on exclusion; its pathophysiology isn't well know and its treatment is only symptomatic.
