Vitamin D helps to stay in better mental shape

Higher Vitamin D levels cause better mental abilities and lower Vitamin D levels caused lower mental abilities. Hence there seems to be an association between Vitamin and cognitive skills, say two studies

Two new studies in the Journals of Gerontology Series A: Biological Sciences and Medical Sciences have established that vitamin D could be a vital component for the cognitive health of women as they get older.

Increasing the Vitamin D in your diet lowers risk of developing Alzheimer’s disease, according to research conducted by a team led by Cedric Annweiler, MD, PhD, at the Angers University Hospital in France.

Similarly, researchers led by Yelena Slinin, MD, MS, at the VA Medical Center in Minneapolis found that less vitamin D among older women increase chances of cognitive impairment .

Very low levels of vitamin D [less than 10 nanograms per milliliter of blood serum] among older women were observed to be linked to higher odds of global cognitive impairment at baseline, and low vitamin D levels [less than 20 nanograms per milliliter] among cognitively-impaired women were associated with a higher risk of incident global cognitive decline, as measured by performance on the Mini-Mental State Examination.

Annweieler’s team’s findings were based on data from 498 community-dwelling women who participated in the Toulouse cohort of the Epidemiology of Osteoporosis study.

Among this population, women who developed Alzheimer’s disease had lower vitamin D intake [an average of 50.3 micrograms per week] than those who developed other dementias [an average of 63.6 micrograms per week] or no dementia at all [an average of 59.0 micrograms per week].

These reports follow an article published in the Journals of Gerontology Series A earlier this year that found that both men and women who don’t get enough vitamin D — either from diet, supplements, or sun exposure — may be at increased risk of developing mobility limitations and disability.

Eurekalert!
