In Chile, there is a strong vitamin D deficiency and the number of people confirmed. In the last National Health Survey (the ENS) found that women aged 15 to 45 years, 84% of the deficit (12.3% of Sur & # 39; oznaya) and in adults over 65 years old has a deficit of 87%.
March & # 39; it Pellerano nutritionist explained that "vitamin D» in more concrete terms and the updated one prohormones that is naturally produced by the direct exposure of the skin to UV sun (90% of the daily requirement), the liver and kidney undergoing enzymatic processes "activated" and then transported via the blood and injected at the cellular level.
It is considered today one billion people in the world suffer from vitamin D deficiency (deficiency), being almost a pandemic, it is important to take responsibility. "This vitamin deficiency is associated with several clinical manifestations in different fields of medicine to influence the prognosis of certain mental health disorders"Says psychiatrist Clínica Santa María, Rodrigo Correa.
In a study published this year, "Trends in the field of neuroscience" (Trends in Neuroscience), University of Queensland, tried to explain why it is so important and how deficiency leads to disorders such as depression and schizophrenia.
There is also installed between vitamin D deficiency and impaired cognition communication. Scientists have shown that vitamin D levels affect the integrity of the "scaffolding" in the brain, calls perineuronal network (PNN), affecting, for example, the ability to remember and learn.
On the other hand, they have come to the conclusion that even though the hippocampus is not a & # 39; is the only part of the brain is used to support connections NPA was the region most affected by the deficiency of vitamin D. In the right part of the hippocampus, also affects vitamin deficiency D., that the left side, which is consistent with that observed in people with schizophrenia.
They explained About 70% of people with schizophrenia have vitamin D deficiencyAnd patients with schizophrenia also tend to have more problems with the right side of the hippocampus.
Vitamin D and depression
Correa said demonstrated a statistical association between vitamin D deficiency and depression. This means that people with low vitamin present risk of clinical manifestations of depressive type and that among people with depression may be more patients with vitamin D deficiency compared to the population, not people with depression.
"He was not able to create a focus for this association, so it is not possible to draw a conclusion, according to the data that vitamin D deficiency occur depression, we know only that both a & # 39; waking often coexist. There are already several follow-up studies that show a better response to antidepressants in patients who are also deficient in vitamin D from the & # 39; is, but there is still more research to methodological projects of the highest level, "said Correa.
The psychiatrist said that, although it is not possible that vitamin D deficiency causes schizophrenia, was that patients with depression and deficiency of vitamin D, most likely, the current depression and anxiety-related symptoms. Furthermore, he came to the conclusion that for depression and schizophrenia, D vitamin deficiency may worsen the prognosis and quality of life of patients.
In addition, vitamin D deficiency causes other symptoms, fatigue & with # 39 is one of the most common. However, Correa said that "has been associated with other diseases, such as cardio-metabolic, cognitive failure, dermatological diseases, immunological and among others. In most cases, these areas also remains to determine the exact role of this vitamin.
What is becoming increasingly apparent, with a & # 39 is an important role of this and other micronutrients in helping to improve the quality of life and help in the treatment of various diseases. "
How do I know if I'm so their levels of vitamin D?
Pellerano doctor explained that the blood tests that can determine if you have optimal levels or failure.
"In accordance with the position of each person, the physician must use concentrates of vitamin D supplements which contain certain international units (IU) per droplet, capsule or vial to dissolve, since only deliver a sample of food and / or stimulate sun exposure (unfiltered solar) not very consistent, "stressed Pellerano.
