A Case Report of Persistent Drug-Induced Parkinsonism After Drug Discontinuation

Abstract

This study examined the effectiveness of Korean medical treatment in a patient with persistent drug-induced parkinsonism after drug discontinuation. The changes in symptoms were assessed using the unified parkinson's disease rating scale (UPDRS), postural instability-gait disturbance (PIGD) score, and the 20 m gait time and steps. After 22 days of hospitalization, the UPDRS, PIGD score, and 20 m gait time and steps showed clinically significant improvement. The improvement persisted after discharge. This study indicated that Korean medical treatment could be an effective alternative therapy for treating persistent drug-induced parkinsonism after drug discontinuation.
