Topical Review: Antidyskinetic Drug Therapy for Pediatric Movement Disorders
Michael R. Pranzatelli, MD
Department of Pediatrics, Neurology, and Pharmacology, The George Washington University, Washington, DC
The pharmacologic armamentarium used to treat dyskinesias in childhood is increasing. Anticonvulsant drugs as a class are still some of the broadest-spectrum antidyskinetic agents, probably because the class includes so many differently acting drugs or because dyskinesias are manifestations of subcortical electrical events. This group is enhanced by recent developments in -aminobutyric acid and glutamate receptor pharmacology, which promise new antidyskinetic drugs. Other drugs acting at receptors for monoamines (dopamine, norepinephrine, and serotonin), acetylcholine, opioids, or histamine may provide symptomatic improvement. Fewer pharmacotherapies address the underlying pathophysiology of movement disorders. Of these, drugs or biologicals for immunomodulation are the most developed, but the group also includes antioxidants, cofactors, metabolic inhibitors, and chelators. There is potential for drugs that block the neurotoxic effects of glutamate to treat movement disorders and reverse or prevent brain injury. Peripheral blockade of focal dyskinesias through botulinum toxin offers a useful alternative to drugs in some patients. (J Child Neurol 1996;11:355-369).
