Simple Hobbies, Active Lifestyles Linked to Lower Dementia Risk
New research suggests that simple lifestyle choices may play a significant role in preventing dementia. A large study by the RAND Corporation found that individuals who engage in hobbies, maintain a healthy weight, and stay active after age 60 have a lower risk of developing dementia.
The study, which analyzed data from over 20,000 older adults followed for three decades, revealed three key factors that stood out: lack of hobbies, obesity, and sedentary behavior after age 60 were strong predictors of dementia.
"This work provides additional evidence about actions that individuals can take to pursue a lifestyle that promotes brain health across the lifespan," said Peter Hudomiet, an economist who led the study.
Interestingly, the study also found that Americans living in the South were more likely to develop dementia, even after adjusting for factors like income. This suggests that regional differences and potential lifestyle factors unique to certain geographical areas may play a role.
While the study didn’t delve into the exact reasons behind these findings, previous research suggests that staying mentally and physically engaged throughout life may protect against cognitive decline. Hobbies stimulate brain function, while exercise promotes healthy blood flow to the brain, thought to be crucial for its long-term health.
Actor Christ Hemsworth found out he has copies of a gene that makes one more likely to develop dementia. The Australian is an avid gym-goer, and also enjoys surfing, boxing and football
The study authors suggest that understanding these risk factors empowers individuals to take preventative steps.
This idea resonates with actor Chris Hemsworth, who learned he had a higher risk of developing dementia while filming a documentary. In response, he has focused on improving his sleep habits, managing stress, and prioritizing nutrition and fitness.
Given that nearly 10 percent of adults over 65 currently have dementia—a number projected to rise to 12 million by 2040 – these findings offer hope for proactive dementia prevention strategies.
This isn’t the first study that has linked exercise as a key way to stave off memory-loss with age. This includes vigorous traditional exercise like running, but some studies have also found that even doing chores can offer a protective benefit
The research was conducted by the RAND Corporation, funded by the biotechnology company Genentech. It encourages individuals to prioritize hobbies, maintain healthy weight, and stay active as they age.
Further research is being conducted to understand why individuals living in the South face a higher risk of dementia and to identify potential preventive strategies.
