Midlife brain changes, especially connectivity, are now seen as a critical window for detecting future dementia risk.
Biomarker tests and MRI-based ageing measures may help predict dementia decades ahead, though not yet reliable for all.
A 2025 MRI pace-of-ageing tool linked faster brain ageing with memory decline and higher dementia risk later on.
Not every person with brain biomarkers will develop dementia; cost and access limit routine use for now.
Lifestyle changes in midlife could reduce dementia risk by nearly half, researchers say.
Experts compare early brain health actions to pension planning for long-term cognitive resilience.
Blood pressure and cholesterol remain early, accessible indicators of brain health at midlife.
There are still gaps and costs before new tests can be used universally in midlife screening.
Researchers emphasize midlife as a critical window to protect brain health before symptoms appear.
The article notes that cognitive decline risk is linked to depression symptoms in midlife among other markers.
The piece highlights a broader view: combining biomarkers, imaging, and lifestyle data improves risk assessment but remains imperfect.
