HealthPhys.orgBritain's 1972 school reform may have lowered dementia diagnoses half a century later
A major study found that staying in school one extra year in the UK cut dementia risk decades later, especially for those with a genetic predisposition.
A new study provides perhaps the strongest evidence yet that education can help mitigate long-term dementia risk.
Researchers found a 1972 UK law requiring students to stay in school one extra year led to fewer dementia diagnoses up to 50 years later.
The study analysed over 100,000 UK Biobank participants and found those with higher genetic Alzheimer's risk benefited most from the extra schooling.
The findings suggest dementia risk is not fixed by genetics alone, and that education and lifestyle factors can meaningfully reduce a person's chances of developing it.
The study found people with higher genetic risk of Alzheimer's benefited most from extra schooling, suggesting lifestyle factors can offset inherited vulnerability, worth discussing with your GP.
