Administration of phosphatidylcholine increases brain acetylcholine concentration and improves memory in mice with dementia

This animal study investigated the effects of phosphatidylcholine (PC) supplementation on memory performance and brain acetylcholine levels in dementia-model and normal mice. Dementia-model mice exhibited significantly poorer memory and lower brain acetylcholine concentrations than normal controls (p < 0.05). After 45 days of daily PC administration (100 mg), dementia-model mice
