Tardive dyskinesia is thought to reflect increased dopaminergic activity
of the central nervous system. To compensate for this by increasing CNS
cholinergic tone, the authors administered oral choline and its natural
dietary source, lecithin, to 5 men with mild to severe tardive dyskinesia
in a nonblind trial. Both choline and lecithin increased serum choline
levels and improved abnormal movements in all patients. Lecithin had fewer
adverse effects.Abstract Teaser
