A Swedish study of healthy older adults suggests that an anti-inflammatory diet rich in leafy greens and sardines may offer added protection against dementia for some seniors, potentially outperforming the Mediterranean diet and highlighting the brain health benefits of mindful eating as people age.
A Mass General Brigham–Boston University–CTE Foundation study of nearly 20,000 NFL players finds death from neurodegenerative disease is about four times higher than in the general population, with dementia and Parkinson’s deaths 3–4x more common; longer careers (five-plus seasons) nearly double the risk versus shorter careers. CTE is considered the primary explanation, though players generally live longer overall due to other protective factors.
Dwayne Johnson will star in and produce Free Byrd, an action-drama directed by Greg Kwedar for Ben Affleck and Matt Damon’s Artists Equity, about a Las Vegas motorcycle stuntman who hides a dementia diagnosis as he risks one last jump; Gill Netter will produce, with a rewrite by Kwedar, as Johnson’s collaboration with Affleck, Damon and Partners continues.
A UF Health AI-assisted study published in Nature Metabolism analyzed records from 2012–2024 (over 50,000 patients with dementia or MCI). It found that about 8% used glucosamine and, among those with MCI, users were 25% more likely to progress to dementia, while among patients with dementia, use was linked to a 25% higher risk of death. The authors caution this is associative, not causal, and call for controlled trials. Glucosamine can cross the blood–brain barrier and may influence protein sugar-tagging in Alzheimer’s brains. If you have dementia or MCI and take glucosamine, discuss alternatives with a clinician; healthy adults face no immediate alarm.
King's College London researchers identify karyoptosis, a nucleus-destructing process triggered by waste buildup in neurons, as a significant contributor to brain cell death in Alzheimer's and frontotemporal dementia. The enzyme p38 MAP kinase marks LaminB1 for destruction, causing nuclei to disintegrate; blocking this interaction delayed cell death in experiments, suggesting a potential therapeutic route. Analysis of human and animal brain cells showed higher rates of karyoptosis in dementia patients (about 35% of frontal-cortex cells) than in healthy controls (about 15%). The study, published in Nature Communications, points to new targets to slow neuron loss and extend treatment windows.
John Nuar cared for his father with dementia in Michigan from 2017–2019 at home before moving him to memory care; rising private-pay costs and limited public aid led them to pay about $120,000 out of pocket. After a period with relatives in Virginia, his father returned to private memory care in Michigan, where costs climbed from roughly $4,200 to $6,600 per month until his death in 2024. The piece highlights the emotional and financial toll of dementia care and urges proactive planning—maxing HSAs for long-term care, completing advance directives and wills—to prepare for future needs.
Dwayne Johnson will star in and produce Free Byrd, an action-drama from Artists Equity directed by Greg Kwedar. Johnson plays a Las Vegas motorcycle stuntman who hides a dementia diagnosis as he risks everything on one final jump. The screenplay originated by Jon Boyer and previously featured on the Black List, with Gil Netter and others producing alongside Artists Equity and Johnson’s Seven Bucks Productions.
Ambitious trials like FINGER and POINTER show that intensive diet, exercise, and social/cognitive programs can yield small cognitive benefits and may modestly slow cognitive ageing, but they have not proven a reduction in dementia incidence. The Lancet Commission lists 14 modifiable risk factors and estimates that up to 45% of global dementia cases could be theoretically preventable, yet translating that into personal risk reduction is uncertain and many factors lie outside individual control. While results are consistently modest and questions about scalability remain, researchers and policymakers continue to weigh the potential brain-health gains against practical challenges as WHO guidelines on risk reduction approach release.
A Swedish study of over 1,800 people aged 60+ followed for up to 15 years found that diets with lower inflammatory potential—rich in vegetables, fruits, nuts, legumes and whole grains and lower in ultraprocessed foods, sugary drinks and red meat—were linked to a reduced dementia risk, including among participants with higher Alzheimer’s biomarkers like p-tau217. While observational and not proof of causation, the findings support a broader brain-health pattern: pair a whole, minimally processed diet with lifestyle factors like physical activity and vascular health, leaning toward Mediterranean-style eating for potential cognitive benefits.
John Nuar and his wife built a home to care for his father, who had dementia, in Michigan (2017–2019); after attempts with vouchers and private care, his father spent about three years in memory care before dying in 2024, with out‑of‑pocket costs totaling roughly $120,000 as monthly fees rose from about $4,200 to $6,600. The family grappled with Medicaid limits and private‑pay options, underscoring the emotional and financial toll of elder care. The piece emphasizes planning ahead—maxing HSAs for long-term care, completing advance directives and wills—and being prepared for steep private-pay costs.
A Swedish study of more than 1,800 older adults followed for up to 15 years found that diets with lower inflammatory potential—rich in vegetables, fruits, nuts, legumes and whole grains and lower in ultraprocessed foods and red meat—were associated with a reduced risk of dementia, including a 29% lower risk among participants with high levels of the Alzheimer’s biomarker p-tau217; while overlapping with the Mediterranean pattern and generally promoting brain health, this observational study cannot prove causation and other lifestyle factors such as exercise, blood pressure control, sleep and social engagement also matter.
The article explains how normal age-related forgetfulness differs from Alzheimer’s-related memory loss. Key warning signs include repeating questions, forgetting recent events, difficulty with familiar tasks, confusion about time or place, and struggles to learn new information, especially when these lapses begin to disrupt daily life. In dementia, memory errors are persistent and retrieval is cue-dependent, with symptoms worsening over time and affecting other thinking skills and independence. While brain imaging can show atrophy, there is no cure for Alzheimer’s, but early diagnosis can help manage symptoms, plan care, address safety, and treat other conditions, underscoring the importance of seeking medical advice when memory problems become frequent or impair daily functioning.
A two-year, randomized trial in 365 older adults at elevated Alzheimer’s risk found that 2,000 mg/day DHA reaches the brain but does not improve memory or slow brain atrophy versus placebo, even among APOE ε4 carriers. Potential reasons include DHA metabolism in the brain and inflammation from cardiovascular risk factors; the relatively young, lightly affected cohort and high dropout limit generalizability. The study reinforces that lifestyle factors (regular exercise, sufficient sleep, and a balanced diet) remain the best available dementia risk-reduction strategy while future work explores DHA metabolism, biomarkers, and personalized approaches.
Eye health can reflect brain health, and untreated vision problems are a major, modifiable dementia risk factor. While vision loss doesn’t directly cause dementia, correcting vision (updating lenses, cataract/AMD treatment) can help keep the brain engaged with the visual world and may reduce dementia risk by up to about 30%. Eye exams and retinal imaging (OCT) might even help track dementia progression. Regular eye care, addressing underlying eye diseases, avoiding smoking, and maintaining vision health can support cognitive function, even after a dementia diagnosis.
A JAMA Network Open study links higher dementia mortality to mid-density neighborhoods (roughly 20–40 people per hectare, about 5,000–10,000 per square mile), typically suburbs near big cities where access to doctors and walkability are limited. Denser cities and rural areas show weaker associations. The research suggests improving nearby primary care, public transport, and safe walking routes could avert tens of thousands of dementia deaths over a decade, with the largest gains in underserved communities.
