Autonomic hyperreflexia in pure progressive autonomic failure: a case report.

A 60-year-old woman suffered from recurrent episodes of fever, hypertension, facial flushing, vomiting, stridor, slowly progressive symptoms of hypohidrosis, and orthostatic hypotension. The episodes were synchronous with elevated catecholamine concentration in plasma and urine. This is an example of paroxysmal autonomic hyperreflexia in a setting of pure progressive autonomic failure.
