Abstract:
Cognitive impairment includes several clinical processes from mild cognitive impairment to dementia, and now it has been a serious public health problem, as there is no effective treatment, it has caused a heavy economic and psychological burden on the family and society, therefore, it seems important to find effective intervention means.Vitamin D is an essential nutrient element for the human body, more and more evidences show that it also participates in many extraskeletal biological reactions, such as nervous system regulatory processes, in addition to calcium and phosphorus metabolism.Several researches have revealed that Vitamin D deficiency is associated with impaired cognition, the mechanisms mediating this link are poorly understood, what's more, for further clinical application, we need to solve the problems like choosing the suitable populations and drug dosage, therefore, this article summarizes and analyzes the effects of serum Vitamin D levels on the cognitive function of different populations, the research progress of Vitamin D intervention research and its possible mechanism of action, hoping to provide references for the clinical application of Vitamin D in the treatment of cognitive impairment.The results show that Vitamin D deficiency is related to the decline of cognitive function in different populations, and Vitamin D can improve cognitive function through reducing Aβ toxicity, anti-inflammatory and anti-oxidative stress and other mechanisms, its supplementation is expected to be an important measure of treating cognitive impairment, in the future, large-scale longitudinal cohort studies are needed to determine the optimal dosage and duration of treatment.
