B Vitamins Have ‘Significantly Favorable Effects’ On Cognitive Scores In Older People

With more than 55 million people worldwide now living with dementia, and nearly 10 million new cases occurring every year, finding effective and safe ways to maintain brain health is becoming an increasingly challenging global health problem. Currently approved pharmaceutical drugs for dementia neither cure nor halt cognitive decline; at best they simply delay the worsening cognitive impairment.

Several previous studies have found B vitamins helpful in averting cognitive decline. In one trial published in 2015, researchers showed that, for participants with high levels of omega-3 fatty acids, a combination of B vitamins prevented brain shrinkage, a hallmark of Alzheimer’s disease.

A recent review of the scientific evidence conducted by researchers from the United States further emphasized the beneficial effects of nutrition for improving cognitive function and dementia. Examining the effects of 21 different nutrients and phytonutrients on cognitive function, the researchers found particularly noteworthy benefits to memory, attention, intelligence, vocabulary, creative thinking, reaction time, comprehension, learning, and other critical measures of cognition.
