The authors report double-blind, placebo-controlled trials of pure
lecithin in the treatment of mania. As in preliminary trials, lecithin
appeared to be nontoxic and effective. Improvement with lecithin was
significantly greater than improvement with placebo in five of the six
patients studied. The concurrent use of anticholinergic agents did not
prevent the antimanic effect of lecithin. The authors discuss the possible
mechanism of action of lecithin, including cholinergic and
membrane-altering effects.Abstract Teaser
