  • Summary

  • We discuss the importance of vision, hearing, and sense of smell to the risk of dementia. Changes in these senses can serve as signals for potential dementia and how addressing these root causes can help prevent dementia down the line. We emphasized the connection between these senses and the nervous system, as well as the role of inflammation in impacting them. We also shared practical strategies such as getting regular vision check-ups, testing hearing, and engaging in olfactory training to improve brain function.
