In a new development in understanding the factors that prevent brain diseases, a recent study indicated that vitamin D levels in middle age may affect brain health many years later.
Vitamin D complications in middle age
According to what was published by The Sun website, people who had higher levels of this vitamin in their thirties and forties recorded lower indicators associated with dementia later.
The study included 793 people with an average age of 39 years. Their vitamin D levels were initially measured, and then brain scans were conducted about 16 years later. The results showed that higher levels of the vitamin were associated with lower tau protein, which is one of the main indicators associated with Alzheimer’s disease.
In contrast, researchers did not find a clear association between vitamin D and amyloid beta, another indicator linked to the disease, indicating that the effect of the vitamin may be specific to certain biological pathways.
Researchers believe that middle age represents a crucial stage during which risk factors can be modified, which may impact brain health later. They also noted that about 34% of the participants suffered from low levels of vitamin D, while only 5% of those taking vitamin D supplements exceeded 5%.
