Movement disorders emergencies. Part 1: Hypokinetic disorders

Abstract

Movement disorders usually do not require emergent intervention; nevertheless, there are acute/subacute clinical settings in which the neurologist is consulted. It is in these circumstances that the neurologist must be prepared to accurately diagnose and properly treat the patient. We have reviewed the literature regarding movement disorder emergencies and divided them into hypokinetic (part 1) and hyperkinetic (part 2) presentations. In part 1, drug-induced syndromes including neuroleptic malignant syndrome, parkinsonism hyperpyrexia syndrome, and serotonin syndrome will be discussed. Emergency complications related to the management of Parkinson disease, including falling, motor fluctuations, and psychiatric issues, will also be reviewed.
