Boston, United States (Enmaeya News) — A recent study has found that low levels of folate, a form of vitamin B9, may significantly increase the risk of dementia in older adults. Participants with folate deficiency were more than three times as likely to develop dementia compared with those with normal levels.

The study followed 518 adults aged 65 and older over two years, tracking blood levels of folate, vitamin B12, and homocysteine, a protein linked to cognitive decline.

Researchers found that participants whose folate levels dropped during the study had a higher incidence of dementia. Those who started with low folate were 3.5 times more likely to develop dementia by the study’s end.

Folate is essential for DNA synthesis and repair. It is found in leafy greens, citrus fruits, eggs, and asparagus. Low folate levels can raise homocysteine, which may damage the nervous system and increase the risk of Alzheimer’s disease and other cognitive disorders.

Experts recommend a balanced diet rich in folate and regular monitoring of folate levels in older adults to support brain health and reduce the risk of cognitive decline.

The research underscores the role of nutrition in protecting the aging brain.
