A New Study Says These Hobbies May Lower Dementia Risk

Key Points:

• A study published in Neurology found that individuals with the highest levels of lifelong learning had a 38% reduced risk of developing Alzheimer's disease and a 36% lower chance of mild cognitive decline compared to those with the least lifelong learning.
• Lifelong cognitive enrichment, including activities from childhood through late life, helps build stronger neural circuits and cognitive reserve, allowing the brain to better handle age-related wear and tear and delay symptoms of dementia.
• The study followed 1,939 adults over an average of eight years, assessing their engagement in mentally stimulating activities across different life stages and found that top lifelong learners developed Alzheimer's or cognitive decline years later than those with less cognitive engagement.
• Even in participants with brain pathologies associated with Alzheimer's, such as amyloid plaques and tau tangles, cognitive enrichment was linked to a slower rate of cognitive decline, suggesting it provides a protective buffer.
• Researchers emphasize that it is never too late to start engaging in meaningful cognitive activities, as maintaining intellectual stimulation throughout life may help delay or offset symptoms of dementia and improve brain resilience.
