Study: Enhancing brain functioning, and preventing cognitive decline, via diet, exercise and cognitive training
“A comprehensive program providing older people at risk of dementia with healthy eating guidance, exercise, brain training, and management of metabolic and vascular risk factors appears to slow down cognitive decline, according to the first ever randomised controlled trial of its kind, published in The Lancet.
After two years, study participants’ mental function was scored using a standard test, the Neuropsychological Test Battery (NTB), where a higher score corresponds to better mental functioning. Overall test scores in the intervention group were 25% higher than in the control group. For some parts of the test, the difference between groups was even more striking — for executive functioning (the brain’s ability to organise and regulate thought processes) scores were 83% higher in the intervention group, and processing speed was 150% higher.”
Study: A 2 year multidomain intervention of diet, exercise, cognitive training, and vascular risk monitoring versus control to prevent cognitive decline in at-risk elderly people (FINGER): a randomised controlled trial (The Lancet)
- Background: Modifiable vascular and lifestyle-related risk factors have been associated with dementia risk in observational studies. In the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER), a proof-of-concept randomised controlled trial, we aimed to assess a multidomain approach to prevent cognitive decline in at-risk elderly people from the general population.
- Findings: Findings from this large, long-term, randomised controlled trial suggest that a multidomain intervention could improve or maintain cognitive functioning in at-risk elderly people from the general population.
