Carbamazepine as a treatment for cataplexy.
Cataplexy is a common symptom associated with narcolepsy. We evaluated a 51-year-old female who developed symptoms of progressive daytime sleepiness with cataplexy. The diagnosis of narcolepsy was confirmed by overnight polysomnogram and was consistent with results of a multiple sleep latency study, and episodes of cataplexy were documented by video-EEG-EMG monitoring. Examination during a catapletic episode was significant for areflexia and paralysis. The frequency of cataplexy increased with fluoxetine, protriptyline and sertraline and the patient developed frank choreiform movements with protriptyline and sertraline. The cataplexy resolved following treatment with carbamazepine. We feel carbamazepine is a potential treatment for patients with refractory cataplexy.
