Postmeningoencephalitic dysautonomia: report of one case.

We present a patient with postinfectious dysautonomia, which developed 2 weeks after a meningoencephalitic episode. The chief dysautonomic symptoms and signs included constipation, urinary dysfunction, anhydrosis, ptosis, and orthostatic hypotension. Neurophysiologic studies revealed no involvement of the somatic nervous system. The dysautonomia recovered gradually 3 months later with minimal supportive treatment.
