We have long suspected that taking care of your heart health with exercise, a diet rich in vegetables, fruits and whole grains, stress management and social interaction could also benefit your brain. Now a French study provides evidence that when you are helping your heart you also reduce your risk of dementia (JAMA, Aug. 21, 2018).
What Is the Evidence on Helping Your Heart?
French researchers enrolled 6626 healthy older volunteers (at least 65 years old) in this study and asked them questions about their heart health such as blood pressure and cholesterol levels. The participants also took tests to determine how well their brains were working. Researchers made sure they followed up to determine if and when the study subjects developed dementia.
Those with the best scores on the American Heart Association metric were significantly less likely to develop dementia during the next eight and a half years.
Helping Your Heart:
The American Heart Association metric included:
- Not smoking
- Body mass index under 25
- Eating fish at least twice a week and consuming vegetables or fruits at least thrice daily
- Regular physical activity
- Total cholesterol under 200 mg/dL
- Fasting blood sugar under 100 mg/dL
- Blood pressure below 120/80 mm Hg
Among those who had few if any optimal results on these items, 1.76 individuals per 100 persons/year developed dementia. In contrast, those who scored optimally on 6 or 7 items were only half as likely to be diagnosed with this brain disorder. (The rate was 0.8/100 person-years.) That is a very significant drop.
Wouldn’t you be willing to follow the rules for helping your heart if you knew it would also cut your risk of dementia so dramatically? We know we would.
