Maturitas: Demystifying the causal link between vitamin D and the onset of depression
Release date: 2015-03-05
March 3, 2015 - Recently, researchers from the University of Western Australia have shown that vitamin D deficiency may not cause depression in later life, but it is a sign of individual depression; researchers It is said that many research evidences so far indicate that there is a partial causal relationship between the loss of vitamin D and the occurrence of depression.
Professor Almeida said that we all know that the brain contains many receptors for vitamin D, which means that vitamin D plays an important role in regulating part of the brain function, so there is a possibility that low levels of vitamin D can cause depression. Symptoms, this is reasonable; however, the study in this paper reveals that the relationship between the two may be a reverse relationship, that is, low levels of vitamin D are the result of depression, because depressed patients tend to exercise less, and sun The number of sun is small.
The researchers found that low concentrations of vitamin D are associated with current depression, but have nothing to do with past or future depression. The lower vitamin D concentration in elderly patients with depression may be a sign of depression, but it does not trigger depression. The reason was that the researchers analyzed 3,105 male individuals between the ages of 71 and 88 in the Perth metropolitan area and measured the body's vitamin D concentration, which has a history of depression or Currently in a state of depression.
The researchers asked questions to participants and used health management data to analyze their past depression, and established a geriatric depression scale for the current patient's depression status. The results showed that practitioners should properly control depression. Vitamin D supplements for the treatment of patients with symptoms; vitamin D is commonly used to treat osteoporosis, and those who are prone to fall.
Based on the data in this study, practitioners should be cautious because there is evidence that excessive vitamin D causes more harm to the body than benefits. For example, a large number of studies have shown that vitamin D intake increases the risk of wrestling and fracture. Of course, the researchers did not eliminate the possibility that vitamin D still has a small amount of antidepressant effects, but the researchers suggest that a large number of randomized placebo control trials should be conducted to eliminate or establish a specific association between vitamin D and depression.
