Memory and other cognitive functions are central to quality of life, independence, and daily functioning. Many adults notice gradual changes in how quickly they recall information or maintain focus during demanding tasks. While some degree of change is a normal part of aging, researchers have identified multiple biological and environmental factors that appear to influence the trajectory of cognitive health over decades.
Understanding these factors is important because it points toward practical, evidence-informed approaches that individuals and communities can consider. This review summarises findings from recent high-quality research, with full transparency that the page is a paid advertisement.
Important Context
This content is paid promotional material. All scientific references are real, independent, peer-reviewed studies available on PubMed. They are presented for educational transparency only. No specific product is claimed to replicate the outcomes observed in controlled research settings. Individual responses to any dietary supplement vary widely based on genetics, overall health, diet, lifestyle, and many other factors.
What Current Research Tells Us About Cognitive Aging
Age-related changes in memory involve multiple interacting systems. The hippocampus, a structure critical for forming new memories, tends to show modest volume reduction in many older adults. Vascular health, chronic low-grade inflammation, oxidative stress, and alterations in synaptic plasticity also contribute. At the same time, the brain retains considerable capacity for adaptation throughout life.
Large-scale epidemiological studies and clinical trials have consistently highlighted several modifiable elements associated with better long-term cognitive outcomes. These include cardiovascular health, regular physical activity, dietary patterns rich in plant foods and healthy fats, quality sleep, ongoing social and intellectual engagement, and management of metabolic factors such as blood pressure and glucose regulation.
“While chronological age and genetics are not modifiable, a substantial proportion of dementia risk appears linked to factors we can influence across the lifespan. Addressing these factors earlier rather than later may offer greater cumulative benefit.”
— Summary of findings from the 2024 Lancet Commission on dementia preventionThe 2024 Lancet Commission: 14 Modifiable Risk Factors
The 2024 update of the Lancet Commission on dementia prevention, intervention, and care identified 14 potentially modifiable risk factors that together account for approximately 45% of dementia cases worldwide. This represents an increase from the 40% estimated in the 2020 report, reflecting new evidence on vision loss and high LDL cholesterol as additional risk factors.
The Commission emphasises that risk reduction strategies should begin early and continue throughout life. Factors relevant in early life include less education; in midlife: hypertension, obesity, hearing loss, traumatic brain injury, excessive alcohol consumption, and high LDL cholesterol; and in later life: smoking, depression, physical inactivity, social isolation, diabetes, and air pollution, plus the newly added vision loss.
These findings underscore that no single intervention is sufficient. A combination of sustained healthy behaviours appears most promising for supporting cognitive resilience.

Dementia prevention, intervention, and care: 2024 report of the Lancet standing Commission
This major commission update synthesised global evidence and concluded that addressing 14 modifiable risk factors could theoretically prevent or delay up to 45% of dementia cases worldwide. New factors added in 2024 include untreated vision loss and high LDL cholesterol. The report provides life-course recommendations for risk reduction.
View on PubMed →Association between healthy lifestyle and memory decline in older adults: 10-year prospective cohort study
In this large population-based cohort of older adults followed for 10 years, adherence to a combination of healthy lifestyle behaviours (including physical activity, healthy diet, moderate alcohol, no smoking, cognitive activity, and social engagement) was associated with significantly slower memory decline. The association held even among carriers of the APOE ε4 allele, a known genetic risk factor for Alzheimer’s disease.

In this 2025 randomised controlled trial, older adults with mild cognitive impairment who received a supplement containing phosphatidylserine showed statistically significant improvements in short-term memory and certain other cognitive measures compared with placebo. The study also observed increases in serum levels of omega-3 fatty acids and neurotransmitters.
View on PubMed →Physical activity as a modifiable risk factor in preclinical Alzheimer’s disease
This study of cognitively unimpaired older adults with elevated brain amyloid found that higher physical activity (measured by pedometer step counts) was associated with slower cognitive and functional decline. Higher activity was also linked to slower accumulation of tau pathology in key brain regions, suggesting a potential mechanistic pathway.

Evidence-Supported Lifestyle Approaches
Across multiple lines of research, several daily habits consistently emerge as associated with better cognitive outcomes. These are not quick fixes but cumulative practices that support brain health over time.
- Regular physical activity — Both aerobic and resistance training are linked to improved cerebral blood flow and support for neuroplasticity.
- Quality sleep — Deep sleep stages are important for memory consolidation and clearance of metabolic waste products from the brain.
- Plant-rich dietary patterns — Diets emphasising vegetables, berries, nuts, fish, and healthy fats (such as MIND or Mediterranean patterns) show associations with slower cognitive decline in observational research.
- Social and intellectual engagement — Meaningful relationships and continued learning are associated with greater cognitive reserve.
- Cardiovascular and metabolic health — Managing blood pressure, cholesterol, and glucose supports vascular integrity, which research connects to long-term brain health.
Nutritional Compounds in Research
In addition to foundational lifestyle measures, researchers continue to investigate specific nutritional compounds for potential supportive roles in cognitive function. Ingredients such as phosphatidylserine, certain botanical extracts, and omega-3 fatty acids have been examined in clinical settings.
Evidence strength varies. No dietary supplement replaces medical care, proven lifestyle measures, or prescribed treatments. Some adults choose to explore high-quality formulas with transparent ingredient lists as one part of a broader wellness approach — always after consulting a healthcare provider.
If you are exploring advanced botanical options formulated with ingredients studied for cognitive support, one such formula is available on the official site.
