[Improvement in quality of life in the elderly. Results of a placebo-controlled study on the efficacy and tolerability of lecithin fluid in patients with impaired cognitive functions].

: Lecithin, a precursor of the neurotransmitter acetylcholine, has a positive effect on brain and memory functions. In a prospective, randomized, double-blind study, the effect of buerlecithin fluid (BLF) was investigated in comparison with placebo in patients with mild cognitive disorders. A total of 96 ambulatory patients (> 55 years) were admitted to the study. Treatment duration was 84 days. In both treatment groups, a clear improvement in all the cognitive parameters tested was seen. The main target measure, the overall Sandoz Clinical Assessment Geriatric (SCAG) score improved by 18.7 (test substance) and 16.4 (placebo) points (p = 0.1620). A statistically relevant improvement of the secondary target parameter, response in the SCAG score, was achieved with BLF (85.4%) in comparison with placebo (62.5%) (p = 0.018). Furthermore, BLF demonstrated significant superiority in a number of the other target measures. The study also confirmed the very good tolerability of BLF.
