00:09Alright, today we are going to talk about purpose in life link to better brain health.
00:15The US population over 65 is projected to grow from 58 million in 2022 to 82 million by 2050,
00:21a 41% increase. With age comes a higher risk of cognitive decline, about 30% of adults over 70
00:28experience mild cognitive issues or dementia. Researchers are exploring ways to protect brain
00:33health and well-being, especially purpose, stands out. A 10-year study in psychological science
00:38tracked 1,702 adults over 65. Participants took annual cognitive tests and completed surveys
00:45measuring autonomy, growth, purpose, and life satisfaction. Those with higher well-being
00:50showed better cognitive performance. Declines in well-being matched declines in cognitive function.
00:54A second analysis confirmed the connection. Higher well-being correlated with higher cognitive
00:58scores, and vice versa, even after adjusting for age, sex, race, education, depression,
01:04and Alzheimer's risk genes. The strongest effects came from purpose, autonomy, and personal growth.
01:10Life satisfaction had a smaller impact. Another long-term UK study followed over 10,000 adults
01:15aged 50-plus for 16 years. Those with higher happiness, confidence, purpose, and control had
01:21better memory over time, regardless of depression symptoms. These studies suggest purpose isn't
01:26just meaningful, it's protective. And unlike fixed risk factors, it's something you can build
01:30at any age. A strong sense of purpose is linked to better brain health as you grow older.
