Movement disorders emergencies: a review

movement disorders (md) encompass acute and chronic diseases characterized by involuntary movements and/or loss of control or efficiency in voluntary movements. in this review, we covered situations in which the main manifestations are mds that pose significant risks for acute morbidity and mortality. the authors examine literature data on the most relevant md emergencies, including those related to parkinson's disease, acute drug reactions (acute dystonia, neuroleptic malignant syndrome, serotonergic syndrome and malignant hyperthermia), acute exacerbation of chronic md (status dystonicus), hemiballism and stiff-person syndrome, highlighting clinical presentation, demographics, diagnosis and management.
