Extra School Year May Cut Dementia Risk
27 Oct
Summary
- An extra year of high school may lower long-term dementia and Alzheimer's odds.
- A 1950s UK education reform showed reduced dementia cases in old age.
- The protection was even stronger for those with high-risk Alzheimer's genes.
A recent study suggests that extending high school by one year could lead to a lower risk of developing dementia and Alzheimer's disease later in life. Researchers analyzed data from over 100,000 U.K. residents, focusing on the impact of a 1957 education reform that raised the minimum school-leaving age from 15 to 16.
This reform increased school attendance by 14%, with those individuals experiencing a nearly 1 percentage point reduction in dementia diagnoses by age 65. The cognitive benefits were even more substantial for participants with genetic predispositions to Alzheimer's disease. The research, published in the Proceedings of the National Academy of Sciences, highlights education's role in dementia prevention.
While the study followed participants up to age 65, researchers noted that the long-term effects on the elderly are still being investigated. Ongoing studies aim to further understand how educational attainment influences Alzheimer's risk over extended periods, offering potential avenues for cognitive health interventions.
