Abstract:
Risk factors for neuroleptic withdrawal dyskinesia in children have not been well studied. The authors present a case of a child who had been treated with a combination of neuroleptics and stimulants for nonpsychotic aggressive behavior. A severe withdrawal dyskinesia precipitated by neuroleptic tapering was ameliorated by discontinuation of the psycho-stimulant. Although stimulants have been reported to increase certain involuntary movement disorders, this is the first known report of psychostimulant exacerbation of withdrawal dyskinesia.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
