A lack of vitamin D could lead to a higher risk of developing dementia and Alzheimer’s disease, suggests a recent study.
Patients with Vitamin D deficiency were found to be twice as likely to develop dementia and Alzheimer’s disease, according to research published in the journal Neurology.
The study consisted of researchers following more than 1,650 people, aged 65 and above, for six years to see if they developed dementia. They measured vitamin D levels from blood samples that were collected at the start of the study and put them into different categories of deficiency including severely deficient, deficient and sufficient.
The different categories were compared to assess the risk of developing dementia and Alzheimer’s disease between them. The results of the study showed that those who were in the severely deficient group had a 125% increased risk of developing dementia or Alzheimer’s disease over the others.
During the study, 171 participants developed dementia or Alzheimer’s disease, which is around 10% of the group.
Some other factors that can lead to an increased risk of dementia can also include an unhealthy diet and nutrition as well as not getting enough physical activity.
Alzheimer’s disease is the 6th leading cause of death in the United States with more than 5 million Americans living with the disease, according to the Alzheimer’s Association.
