The rising number of child and adolescent psychiatry referrals, along with the growing use of medications for mental health problems, has led to an increased incidence of drug-induced parkinsonism (DIP). This report aims to document a patient with DIP, which is rarely seen in child and adolescent psychiatry clinical practice, and to present the successful treatment of this patient with amantadine. Amantadine represents an evidence-based pharmacologic option for treating drug-induced parkinsonism.
