Having a sense of purpose in life may help people live longer. Now, new research from the University of California in Davis shows that having a sense of purpose in life may have another benefit as people age: reducing the risk of dementia. The new study ... found that people who reported a higher sense of purpose in life were about 28% less likely to develop cognitive impairment—including mild cognitive impairment and dementia. The protective effect of having a purpose was seen across racial and ethnic groups. It also remained significant even after accounting for education, depression, and the APOE4 gene, which is a known risk factor for Alzheimer’s disease. “Our findings show that having a sense of purpose helps the brain stay resilient with age,” said Aliza Wingo, senior author. “Even for people with a genetic risk for Alzheimer’s disease, sense of purpose was linked to a later onset and lower likelihood of developing dementia.” The findings support the idea that psychological well-being plays a key role in healthy aging, said Thomas Wingo, a co-author of the study. Wingo hopes future studies will explore whether purpose-building interventions can help prevent dementia. “What’s exciting about this study is that people may be able to ‘think’ themselves into better health. Purpose in life is something we can nurture,” he said. “It’s never too early — or too late — to start thinking about what gives your life meaning.”
