espite growing evidence supporting the positive role nutrition plays in dementia prevention, nutrition is rarely employed as a prevention strategy. A new study may change that. The linkages among nutrition and brain function are made clear in the results from a first-ever randomized controlled trial of its kind led by Miia Kivipelto, MD, PhD published today in the Lancet.
The two-year research study measured the effects on brain function of an intervention — which included nutritional guidance and management of metabolic risk factors — for age-related dementia. Using the Neuropsychological Test Battery (NTB) test, intervention group scores for overall brain function were 25 percent higher. For executive functioning, intervention group scores were 83 percent higher, and processing speed was 150 percent higher.
