IntroductionBlepharospasm is uncommon in Parkinson's disease, especially in the peak-dose dyskinesia period.Case presentationWe herein present the case of a patient with PD who developed blepharospasm in the peak-dose dyskinesia period. The symptom was improved by taking amantadine.ConclusionThe current report expands the phenomenology of peak-dose dykinesia in PD to include dystonic blepharospasm.
