Avoiding Three Midlife Factors Linked to 13 More Dementia-Free Years
NBC and Time report a long-term study indicates avoiding three midlife health factors may add roughly 13 dementia-free years.

NBC News and Time Magazine report that a long-term study indicates people who avoid three specified factors in midlife are linked to about 13 additional dementia-free years. Coverage characterizes the items to avoid as three “health factors” or “three things” in midlife, but does not list those factors in detail.
Study and media coverage
Both outlets describe the finding as coming from a long-term study and frame the result as an association rather than a demonstrated cause. Reports say the difference amounts to roughly 13 more years without dementia for people who do not have the three midlife factors, and they present the result as a notable correlation identified by researchers.
Limitations and unanswered questions
The media coverage does not provide the primary study’s full details in their reports, including the study design, which specific factors were analyzed in full, or whether analyses controlled for all potential confounders. Because the published reports summarize the study, the finding should be read as an association reported by the study rather than proof that avoiding those factors will directly cause the additional dementia-free years.
The reports highlight a potentially important relationship between midlife health and later-life cognitive outcomes, while leaving key methodological and causal questions open for readers and researchers to follow up on.
