Dear, Vitamin D deficiency seems to be more dangerous than you think, it affects not only your health, but also that of the fetus, as well as diseases that you do not understand at all.
The causes of schizophrenia have been a mystery for a long time, until new research establishes a connection between vitamin D deficiency at birth and the onset of schizophrenia later in life.
Although most patients do not show signs of disorientation before the age of 15, neurologists have already assumed that this started in the womb.
More and more evidence supports this idea, but the specific and precise mechanisms that underlie it are still unknown, as there is strong evidence that the disease is hereditary and, in some cases, at least more than one. influencing factor.
Vitamin D deficiency is more serious than you think
We know that vitamin D plays a vital role in the absorption of calcium in the bones and that its absence can lead to disorders such as osteoporosis and rickets, but we have not yet been able to identify all the functions performed in the body.
Now, based on these recent data, this nutrient appears to play a role in schizophrenia.
"Schizophrenia is a group of brain disorders that we do not understand well and that is accompanied by symptoms such as hallucinations, delusions and cognitive deficits," said John McGrath, neuroscientist of the Queensland Brain Institute in Australia and from Aarhus University in Denmark.
"This study, published this week and shared by a large sample of Danish infants, shows that infants with vitamin D deficiency at birth are 44% more likely to develop schizophrenia at puberty," he said. declared.
The study, conducted in Denmark, benefited from the Danish National Register, a database of health information used in the study of trends and statistics in health.
The researchers identified 2,602 people born between 1981 and 2001 with schizophrenia in adolescence and then examined the vitamin D concentration in blood samples taken at birth.
They then compared them to peers of the same age and gender who did not suffer from schizophrenia. The researchers said the results showed a clear difference: vitamin D could be responsible for 8% of schizophrenia in Denmark.
This evidence corresponds to a link previously discovered by scientists between birth in winter (or spring) in high latitude regions such as Denmark – the period of the year when solar radiation is significantly reduced, which promotes the formation of vitamin D in the body – and increases. Risk of schizophrenia.
The researchers speculated that the cause could be vitamin D deficiency and took advantage of the Danish database to test their hypothesis, Science Alert reported.
"This disorder is so serious that we can not neglect any evidence," McGrath said in a study published in Scientific Reports. We must follow all evidence as expeditiously as possible, even if some evidence is excluded or unusual. "
"What we are looking for in the first place is to prevent people with schizophrenia," he said. "I think the experience of the link between folate and spina bifida is a good example of the simplicity, cost and safety of the work done." Brain disorders.
Previous studies have also revealed a genetic relationship between schizophrenia and autism, a relationship between autism and vitamin D deficiency before birth.
It is unlikely that this important result is the complete explanation of the disease. Schizophrenia is still prevalent in very sunny areas and can occur in people with normal vitamin D levels at birth.
But after researchers have noticed this association, the research team plans to continue studying this hypothesis, hoping that their research will result in a very effective and simple way to prevent at least some schizophrenia.
"The next step is to conduct randomized clinical trials involving vitamin D supplementation for pregnant women with deficiency, to study its effects on brain development and the risk of neurodevelopmental disorders such as lymphadenopathy. autism and schizophrenia, "he said.
