Understanding the Links among Maternal Diet, Myelination, and Depression: Preclinical and Clinical Overview

Abstract

Depression is one of the most common mental disorders in the general population, and multiple mechanisms are involved in the etiology of this disease, including myelination. According to the Developmental Origins of Health and Disease (DOHaD) hypothesis, maternal diet affects the lifetime of the individual during adulthood and may contribute to the development of neuropsychiatric disorders. Additionally, the intensive processes of myelination contribute to the development of the central nervous system in the perinatal period, while any alterations during this crucial process providing the physiological functioning of neurons may lead to neuropsychiatric disorders in the next generation. The present review summarizes the current knowledge on the role of the myelin-related changes in depression, as well as the crosstalk among maternal malnutrition, myelination, and depression in preclinical and clinical settings.
