Key Takeaways

Plain English Takeaway

A mix of healthy eating, exercise, brain training, and regular health checks can help older adults keep their minds sharp and slow down memory problems.

Study Aim

The main goal of this study was to find out if a combination of healthy diet, physical exercise, mental exercises, and careful monitoring of heart health could prevent or slow down memory and thinking problems in older adults who are at risk for cognitive decline. Simply put: The study wanted to see if a healthy lifestyle program could help older people keep their minds healthy.

Study Design

This research used a randomized controlled trial (RCT), which means participants were randomly assigned to different groups. The study lasted two years and included older adults from the general population who were at risk for memory and thinking problems. One group received a multidomain intervention, which included advice on healthy eating, regular physical exercise, mental training activities, and regular checks and management of heart and blood vessel health (vascular risk monitoring). The control group received standard health advice but did not get the full intervention program. Simply put: The study compared a group doing a special health program to a group getting usual advice, to see which worked better for brain health.

Findings

The study reveals that older adults who took part in the multidomain intervention had better or more stable memory and thinking abilities compared to those who only received standard health advice. The results suggest that combining healthy eating, exercise, mental training, and regular health checks can help prevent or slow down cognitive decline in people at risk. The authors recommend that similar programs could be used more widely to help older adults maintain their brain health. Simply put: The special health program helped older people keep their minds sharp better than just regular advice.

The REAL Dementia Risk Factors Doctors Won't Tell You

Dr. Gil Carvalho of Nutrition Made Simple reviews the latest research on preventing and combatting dementia risk that he says have changed the way he thinks about the inevitability of dementia. The 2024 Lancet Commission report as mentioned by other users, provides 14 modifiable lifestyle factors that could prevent 45% of dementia cases, including 2 new factors that were added due to the recent weight of evidence: Vision Loss and Plaque buildup as measured by High LDL Cholesterol.

In addition to the Lancet report, he also reviews a two year Finnish landmark trial that gave high risk dementia individuals a targeted program to prevent cognitive decline. The intervention included a healthy diet, both cardio and weight lifting exercise, cognitive training exercises, regimented social activity, and measuring and managing health parameters through a nurse and doctor. The the intervention group saw cognitive performance improved by 25% versus the control group including 83% improvement in executive function and 150% increase in processing speed.

Even better, a follow on study found the effects lasted 7 years after the intervention if the lifestyle was maintained. And the groups that benefitted the most had the greatest genetic risk!

The biggest takeaway to understand was given by one of the overseeing researchers:

What is good for your heart is also good for your brain

-Professor Miia Kivipelto

This means that associated risks for heart disease and other CVD diseases are also risks for dementia. That means getting things like your blood pressure, blood sugar, and APOB checked and managed have the double impact of preventing dementia.

Dr Carvalho summarizes his personal list of things he does personally as his own checklist to combat dementia.

Check blood pressure often - consistently high blood pressure overtime damages your blood vessels
Regular Exercise - incorporate cardio and weight lifting regularly, 3 to 5 times a week
Healthy Diet - especially monitoring diabetes and blood sugar risks
Blood Work - get a lipid panel, measuring your LDL, APOB, and LP(A) which are signs of plaque buildup
Hearing and Vision Check - even if you're young, hearing loss and vision loss have high association with dementia risk either due to additional cognitive strain or social isolation
Cognitive Activity - keeping the mind healthy with continued learning and puzzles
Social Activity - Social isolation adds to your personal stress which may triggers cortisol that damages your brain long term. Dr. Carvolho says that this is one of the beneficial and underutilized factors for preventing dementia.
