Pure autonomic failure
Pure autonomic failure is defined as an idiopathic sporadic disorder characterized by orthostatic hypotension, usually with evidence of more widespread autonomic failure and no other neurologic features. It remains a diagnosis of exclusion. Specific attention should be directed toward some of the clinical features that were found to predict future development of multiple system atrophy or dementia with Lewy bodies in cases that are initially diagnosed with pure autonomic failure.
