Carbamazepine-responsive chorea in a toddler with semilobar holoprosencephaly: Case report
Discussion: Despite significant morbidity, there are few cases described in the literature of chorea and movement disorders in HPE and no effective treatment strategies described. Carbamazepine is an antiepileptic drug that stabilizes voltage-gated sodium channels and is the most effective treatment for paroxysmal kinesigenic dyskinesia. Although it has been used successfully in the treatment of different movement disorders, few therapeutic trials have been reported. The mechanism by which carbamazepine alleviates chorea is still unknown but may be justified through the blocking of post-synaptic dopamine receptors and stimulation of cholinergic pathways.
