A recent scientific study has revealed that adults who completed an additional year of schooling during adolescence had a lower risk of developing dementia and Alzheimer’s disease later in life compared with those who left school at an earlier age.
According to the findings reported by the American newspaper The Washington Post, based on medical records from the UK Biobank, researchers examined the impact of an educational reform introduced in the United Kingdom in 1972. The legislation required teenagers born on or after September 1, 1957, to remain in school until the age of 16, whereas the previous minimum school-leaving age was 15.
This reform enabled researchers to compare individuals with similar socioeconomic backgrounds and life experiences who were subject to different educational requirements depending on their dates of birth. The approach helped distinguish the direct effects of formal education from those associated with social and economic circumstances.
The researchers observed lower rates of dementia among individuals who had completed an additional year of schooling. Notably, this protective effect was also identified among people with a higher genetic predisposition to the disease.
Commenting on the findings, Leandro Carvalho, an associate professor of economics at the University of Southern California and a co-author of the study, emphasized that the results suggest genetic risk can be mitigated and should not necessarily be considered inevitable. He also noted that the research team intends to continue monitoring the participants as they grow older.
The researchers believe these findings highlight the importance of investing in education from an early age as a potential strategy for reducing the risk of neurodegenerative diseases later in life. However, they stress the need for further research and long-term follow-up to better understand the lasting effects of education on brain health among older adults.
