Avoiding 3 health risks in middle age linked to 13 more years without dementia

Key Points:

• A study led by NYU Langone Health found that middle-aged adults who avoid high blood pressure, diabetes, and smoking can gain nearly 13 additional dementia-free years of life.
• The research analyzed data from over 12,000 dementia-free participants aged around 56, tracking their health for an average of 26 years.
• Participants without the three risk factors averaged 30 dementia-free years, while those with all three conditions averaged only 17 years before dementia onset or death.
• The study highlighted demographic differences, with women generally experiencing longer cognitive health than men, and Black participants showing fewer dementia-free years compared to White participants under similar risk conditions.
• Researchers emphasized the importance of midlife vascular risk reduction for preserving brain health and suggested targeted prevention efforts for vulnerable populations, though they noted the observational nature of the study limits causal conclusions.
