How genetics, lifestyle promotes cognitive health in the elderly

For the first time, researchers from the University of Hawaii in Mānoa have studied how work, volunteering and leisure activities affect brain health in the elderly from various horizons, while taking into account a genetic risk factor for Alzheimer’s disease. The study, led by the Thompson School of Social Work & Public Health, shows that staying active can help keep their minds with age.

The researchers examined the link between these activities and cognitive operationBy focusing on the apolipoprotein e (APOE) ε4 – A genetic risk factor for Alzheimer’s disease, using data of more than 7,600 participants in the health and retirement study , a national survey.

The study is headed by Yeonjung Jane Lee, deputy professor of social work, and was published in the Journal of Alzheimer’s Disease Reports.

Key conclusions

The study revealed that work, volunteering and work in activities such as word games, the use of computer and socialization improved cognitive health for everyone. However, the advantages depended on genetics. For those who do not have the APOE ε4 allele, part -time work and high intensity volunteering were the most effective.

“Even if someone has the APOE ε4 allele, modifiable factors like cognitively stimulating activities can promote cognitive health,” said Lee. “These results highlight how the integration of such activities in older adults“Life can support aging.”

Researchers highlight the importance of offering accessible activities to help reduce the impact of Alzheimer’s disease and other dementia, especially in various populations.
