However, a recent American study conducted by Wake Forest University in North Carolina and Brigham Hospital indicated that daily intake of vitamins (Multivitamins) prevents cognitive decline in the elderly.
The study is the first of its kind to show that it can benefit brain function in aging, according to a report published Wednesday by the British newspaper “The Guardian”.
It can slow cognitive decline
A study of more than 2,200 people over the age of 65 found that daily supplements can slow cognitive decline by 60%, or nearly two years, with the most substantial effects seen in older adults with a history of cardiovascular disease.
But while the findings encourage experts in Alzheimer’s disease and dementia, the study warns that larger studies are needed to confirm the effect before recommending daily multivitamins to help protect older adults from cognitive decline.
They also noted that previous testing of the nutritional supplement had no effect on the disease.
Writing in the journal Alzheimer’s and Dementia, the researchers explain that the study is preliminary evidence in a long-term randomized study in women and men that shows that daily use of vitamins and minerals can improve cognition.
Professor Laura Baker, co-lead researcher of the Cosmos study at Wake Forest University, said it was too early to recommend a daily multivitamin to prevent cognitive decline.
He added that more research is needed in a larger and more diverse group of people despite promising results, noting that work needs to be done to better understand the benefits of multivitamins on cognition in the elderly.
There is no cure for dementia
Interestingly, dementia has become a major global health challenge in light of the lack of drugs capable of treating any common type.
In the UK, some 850,000 people are living with dementia, most of them with Alzheimer’s disease or “vascular dementia”.
People over the age of 65 who have diabetes, high blood pressure, high cholesterol and depression are the most at risk.
