  • Publication number: 20230310356
    Abstract: A method for ameliorating or treating brain damage and mild cognitive impairment includes administering a composition including glutamine or a salt thereof as effective component to a subject in need thereof. Glutamine as the effective component not only can restore the memory and cognitive ability impaired by stress but also can suppress a damage on nerve cells, reduce the amount of ROS/RNS and other related proteins in brain tissues, and enhance synaptic plasticity. When the animal model of Alzheimer's disease is fed with glutamine, cognitive ability of the animal is improved and accumulation of A?42 is suppressed.
