One study reports that infants with vitamin D deficiency have an increased risk of schizophrenia later. The details of the study are published in the journal Scientific reports.
The causes of schizophrenia remain mysterious. If you know a genetic origin, this does not explain everything. And if the vitamin D could it play a role? A recent study of 2,602 individuals confirms a link between vitamin D deficiency at birth and the development of schizophrenia at the age of 15. A discovery that could help prevent some cases treat pregnant women with vitamin D deficiencies
An increased risk of 44%
"Schizophrenia is a group of brain disorders little understood, characterized by symptoms such as hallucinations, delusions and cognitivesays neuroscientist John McGrath of the Queensland Brain Institute in Australia and lead author of the study. The new study published this week shows that, on a very large sample of Danish children (…), those with a vitamin D deficiency at birth has a 44% increased risk of contracting schizophrenia in adulthood ".
The shortcomings do not explain everything
As part of this study, the researchers analyzed the medical data available from 2,602 people born between 1981 and 2000 diagnosed with schizophrenia. The researchers here focused on the concentration of vitamin D in blood samples taken at birth. Comparing these data with those of the same sample – diagnosed this time as "non schizophrenic" – the researchers then saw difference.
Of course, the the link does not explain everything. Schizophrenia is also prevalent in people with normal levels of vitamin D at birth. It will still be interesting to dig this up track. The disorders of schizophrenia can be really very heavy. However, treating a vitamin D deficiency could be a simple and inexpensive way to prevent certain cases.
"The next step is to drive clinical trials randomized vitamin D supplements in pregnant women with vitamin D deficiency, the researcher continues. The idea will therefore be to examine the impact on children's brain development and the risk of neurodevelopmental disorders such as schizophrenia. ".
