How to avoid dementia – what the science says

24 days ago

Lifestyle interventions like improved diet, exercise, and cognitive stimulation show modest cognitive benefits but have not reduced dementia incidence.
The Lancet Commission identifies 14 modifiable risk factors, estimating 45% of dementia cases could theoretically be prevented globally.
Trials such as FINGER and POINTER report small statistically significant effects on cognitive tests, but critics question scalability and personal responsibility focus.
Dementia cases are projected to rise dramatically, with growing burden in low- and middle-income countries.
Upcoming results from international trials and WHO guidelines aim to refine risk-reduction strategies amid debate over societal versus individual approaches.

Historically, potatoes were believed to cause leprosy due to their unusual appearance and growth method.
AI can now generate full academic papers from spurious correlations, potentially making some academic fields redundant.
2025 is projected to have the fewest US murders since reliable data began in 1960.

COVID-19 is far worse than seasonal flu, with significant mortality and strain on healthcare systems.
Social distancing, hand washing, and coughing hygiene are effective measures to slow the spread.
Warmer weather may slightly reduce transmission but strong measures are still necessary.

When one spouse is diagnosed with dementia, the other partner's risk increases by about 70% (74% for wives, 69% for husbands).
The pattern holds across dementia types, including Alzheimer's and vascular dementia, and is similar for women and men.
Spouses with lower incomes and fewer children face the widest gaps in absolute risk, likely due to thinner caregiving support.

Current situation unclear: cases rising in many countries, but vaccine efficacy against severe disease remains high.
Potential double epidemic with flu, but flu cases currently low; vaccination can reduce unvaccinated by 25% in communities with 80% coverage.
Ventilation and air purifiers (including simple filters) are effective in reducing transmission.

War is seen as inevitable in the development community, but new research is exploring ways to prevent it, especially in developing countries where conflicts cause long-term economic damage.
Traditional development approaches are less effective during war due to disrupted supply chains and local dynamics, yet treating war as an inevitability is overly fatalistic.
Advances in conflict studies, using large datasets and randomized field experiments, are improving understanding of violence causes, though measuring intervention impacts remains challenging.
