Paroxysmal Nonkinesigenic Dyskinesias Responsive to Carbamazepine in Fahr Syndrome: A Case Report.
OBJECTIVE
This study aimed to report the case of a patient with paroxysmal nonkinesigenic dyskinesias and Fahr syndrome who had a marked response to carbamazepine.


METHODS
We present the case of a 57-year-old female patient with episodes of paroxysmal choreoathetoid dyskinesias in the oromandibular region and distal region of upper and lower extremities, with fluctuating dystonic postures in the same distribution; duration was variable ranging from 30 minutes to 3 hours. Laboratory studies were consistent with primary hyperparathyroidism with bilateral brain calcifications.
