Unexpected Falls in Schizophrenia: Clozapine-Induced Negative Myoclonus

OpenAlex İngilizce

Myoclonus, characterized by sudden involuntary muscle contractions, can occur in a variety of conditions, including as a side effect of clozapine, which is used in the treatment-resistant schizophrenia. This case study describes a 48-year-old female patient who developed negative myoclonus, manifested by knee flexion and falls, after starting clozapine. Despite dose reduction and the addition of valproic acid, symptoms persisted, highlighting the dose-dependent nature of clozapine-induced myoclonus and the need for clinicians to recognise this risk.
