Abstract

As people live longer, the burden of aging-related brain diseases, especially dementia, is increasing. Brain aging increases the risk of cognitive impairment, which manifests as a progressive loss of neuron function caused by the impairment of synaptic plasticity via disrupting lipid homeostasis. Therefore, supplemental dietary lipids have the potential to prevent brain aging. This review summarizes the important roles of dietary lipids in brain function from both structure and mechanism perspectives. Epidemiological and animal studies have provided evidence of the functions of polyunsaturated fatty acids (PUFAs) in brain health. The results of interventions indicate that phospholipids—including phosphatidylcholine, phosphatidylserine, and plasmalogen—are efficient in alleviating cognitive impairment during aging, with plasmalogen exhibiting higher efficacy than phosphatidylserine. Plasmalogen is a recognized nutrient used in clinical trials due to its special vinyl ether bonds and abundance in the postsynaptic membrane of neurons. Future research should determine the dose-dependent effects of plasmalogen in alleviating brain-aging diseases and should develop extraction and storage procedures for its clinical application.
