In addition, other studies showed that rats deprived of Vitamins D resulted in brain damage and poor performance on cognitive tests. Also, heart attack survivors were less likely to recover cognitive function if they had low levels of this vitamin.
Now comes another study from Australian researchers, that shows a direct link between vitamins d levels and good memory function.
Vitamins D: Benefits Your Short, Long-Term Memory
Over 1 billion people world wide suffer from a vitamins d deficiency and there is a strong link between low vitamin d levels and memory deficits.
In their experiment, the Australian researchers deprived mice of vitamin d for twenty weeks. On cognitive tasks, the deprived mice scored significantly worse compared to the control group. Brain scans showed a reduction of cells in the hippocampus brain area that are responsible for memory formation.
There was also a significant reduction in both the number and strength of nerve connections between neurons in the hippocampus. In addition, impaired functioning in the hippocampus may contribute to symptoms of schizophrenia, such as memory loss and cognitive distortions.
The next step is to take a vitamin deprived group and resuscitate them with Vitamin D in their diet and test them again. Does memory function and cognition return? And if so, to what level(s)?
