Evidence-informed brain-health education for adults 55+
Brain Health Knowledge Center
A curated library for understanding what published research says about brain health and cognitive aging—and just as importantly, what it does not tell us about any one individual.
How we approach the evidence
Brain-health research is complex. Associations found in large groups do not automatically become predictions for one person, and no single paper, commission, or risk estimate should be treated as the whole story. BrainPreserve articles are designed to explain the evidence in plain language while keeping uncertainty, study limitations, and the distinction between population-level findings and individual medical judgment visible.
- Systematic reviews and meta-analyses when appropriate
- Major cohort studies
- Consensus statements and guidelines
- Multiple high-quality sources rather than one favored authority
- Plain-language explanation for adults 55+
- Clear limitations and uncertainty
- Population-level context—not individual prediction
- References and updated dates on substantive articles
Cornerstone topics
The questions this library is built to explore
Cognitive decline & modifiable factors
What prevention research can and cannot support; how modifiable factors are studied; and why population-level findings need careful interpretation.
Movement, fitness & function
Exercise, physical activity, strength, aerobic fitness, mobility, balance, and their associations with healthy aging and cognitive health.
Sleep, stress & social connection
How sleep, psychological stress, isolation, engagement, and social connection are studied in relation to cognition and aging.
Blood pressure & cardiometabolic health
Blood pressure, weight-related health, vascular factors, and other health measures frequently examined in cognitive-aging research.
Hearing, vision & sensory health
What research suggests about hearing and vision changes, cognitive health, participation, and healthy aging.
Nutrition patterns & healthy aging
Dietary patterns and nutrition research presented as general education—not individualized medical nutrition therapy.
