A new major study has pinpointed which middle-age health factors matter most for delaying dementia, and the findings are striking: avoiding just three specific risks could buy you 13 extra dementia-free years. Researchers from NYU Langone tracked over 12,400 adults for an average of 26 years to reach this conclusion.
1. Quit smoking. Smoking remains the major, most modifiable dementia risk factors identified in the study, and even ex-smokers eventually reach a dementia risk similar to those who never smoked.
2. Control high blood pressure. Hypertension in midlife has harmful effects on blood vessels in the brain, making it one of the three biggest predicator, of early dementia onset in the study.
3. Manage or prevent type 2 diabetes. Diabetes raise dementia risk alone by as much as 50%, and it shares underlying causes with high blood pressure, including poor diet, inactivity, and excess weight.
As per research, the participants who avoided all three risk factors around age 56 remained dementia-free for roughly 30 years, compared to just 17 years for those with all three, a difference researchers called too large to achieve “by any medication.” Around 45% of dementia cases are believed to stem from modifiable risk factors like these, according to the study’s authors.
Experts recommend a lower-fat, plant-based diet, regular physical activity, and regular blood pressure and blood sugar checks starting around age 48. Quitting smoking must ultimately come from personal motivation, but tools like nicotine patches, therapy programs, and even acupuncture can meaningfully support the process once someone is ready.
