A new study from Stanford University suggests that brain age could be a strong predictor for lifespan. Researchers analyzed blood samples from 44,498 individuals aged between 40 and 70 years old and found that those with younger brains tended to live longer.
The study, which used a blood analysis technique, estimated biological ages for 11 key organs in the body, including the brain. The results showed that people with older brains were more likely to die within a 15-year period compared to those with brains of similar chronological age.
However, it’s essential to note that this is not the only factor affecting lifespan. Other studies have linked poverty, obesity, and physical activity to brain aging. Brain aging is also influenced by disease, which can lead to organ aging.
The study’s findings have significant implications for understanding the relationship between brain age and lifespan. Researchers hope to use this approach to test new longevity interventions and identify key variables that contribute to disease and mortality.
While the study’s results are promising, it’s crucial to consider the limitations of the research. Future studies will aim to build upon these findings by focusing on fewer organs and analyzing specific diseases.
