How do you treat paroxysmal Kinesigenic dyskinesia?

Carbamazepine is considered the first-choice treatment, as phenytoin has a less favourable drug profile. Other medications described in case reports and case series as alternative treatments include lamotrigine, levetiracetam, oxcarbazepine, topiramate, valproate, and benzodiazepines such as clonazepam.
