Can a positive outlook on life help protect your brain as you age?

In this evidence-based report, we explore a remarkable new study published in the Journal of the American Geriatrics Society, revealing that higher levels of optimism are associated with a lower risk of developing dementia over time.

Researchers analyzed data from more than 9,000 older adults followed for up to 14 years and found that optimistic individuals were significantly less likely to develop cognitive decline—even after accounting for age, lifestyle, depression, education, and chronic health conditions.

In this video, you'll discover:

• The latest scientific findings on optimism and dementia
• How positive thinking may influence brain health
• The connection between mental well-being and healthy aging
• Why researchers believe optimism could become an important factor in future dementia prevention strategies
• The limitations of the study and what scientists still need to investigate
