This landmark 2024 update synthesizes global evidence showing that up to 40-45% of dementia cases may be preventable by addressing 14 modifiable risk factors - including education, hearing and vision loss, hypertension, smoking, physical inactivity, diabetes, depression, social isolation, and air pollution.

A 2023 cross-sectional survey examining public awareness of 13 modifiable dementia risk factors among 551 Irish adults. Findings reveal critical awareness gaps: while head injury (90.9%), low mental stimulation (85.3%), and alcohol consumption (77.8%) were well recognized, many other key risk factors remained unknown. Results demonstrate that awareness levels vary significantly by education, gender, and age, emphasizing the need for tailored prevention messaging.

This 2022 validation study demonstrates BOCA's effectiveness as a self-administered digital cognitive assessment. Testing 100 participants (50 with cognitive impairment, 50 controls), the study confirmed strong discriminative ability between groups (p < 0.001), excellent test-retest reliability (R = 0.94), and minimal practice effects over 10 consecutive days. The 10-minute assessment evaluates eight cognitive domains and showed strong correlation with Montreal Cognitive Assessment (MoCA) (R = 0.90).

This pioneering 2024 randomized controlled trial demonstrated that comprehensive lifestyle modifications—including plant-based nutrition, exercise, stress management, and group support—produced measurable improvements in cognitive function and reduced disease progression in patients with mild cognitive impairment or early Alzheimer's disease over 20 weeks. The intervention group showed significant improvements across multiple cognitive assessments while the control group declined, with supporting evidence from biomarker changes including increased plasma amyloid ratios and beneficial microbiome modifications.

This 2025 randomized controlled trial of 6,104 Australian adults (aged 55-77) demonstrates that personalized online multidomain lifestyle coaching significantly improves cognitive outcomes over 3 years. Participants receiving tailored interventions in physical activity, nutrition, cognitive activity, and mental health showed significantly better global cognition (difference: 0.18 z-score, P < 0.001) compared to controls. The scalable digital intervention supports population-level dementia prevention.

This 2025 multicenter US randomized clinical trial of 2,111 older adults (60-79 years) at risk of cognitive decline demonstrates that structured, higher-intensity lifestyle interventions significantly outperform self-guided approaches. The structured intervention, targeting physical exercise, MIND diet adherence, cognitive challenge, social engagement, and cardiovascular health, produced greater improvement in global cognition (0.243 SD per year vs 0.213 SD per year; difference: 0.029 SD, P = .008) over 2 years. Results affirm the value of supervised, accountable programs like the Boston Cognitive Program.

This research examined the prevalence of cognitive impairment among 656 individuals receiving addiction treatment using the Montreal Cognitive Assessment (MoCA) screening tool. Results revealed that roughly one-third of patients experienced cognitive impairment. Those dependent on alcohol showed weaker memory performance compared to cannabis users, while opioid users displayed reduced spatial reasoning abilities versus cannabis or stimulant users. Age proved significant, with younger participants performing better than older ones. The researchers concluded that early cognitive screening should become standard practice at treatment initiation to enhance outcomes and support more effective interventions.
