How to Know If Your Brain Is Already Changing

Nearly half of all dementia cases worldwide didn't have to happen — and most people whose brain is already quietly changing have no idea it's underway. In this video, Dr. Nolan Blake breaks down the 14 modifiable risk factors identified by the 2024 Lancet Commission, how each one actually affects your brain, and what a real prevention protocol looks like. In this video, you'll learn: • Why untreated hearing and vision loss are two of the most overlooked dementia risk factors • What actually happens in your brain during deep sleep — and why one bad night matters more than you think • The surprising link between muscle loss, balance, and long-term brain health • The invisible type of body fat driving silent, long-term brain inflammation • The earliest warning signs in speech, memory, and navigation — and when they cross the line into something worth a doctor's visit This video is for adults 50 and older who want a clear, honest breakdown of brain health — not vague reassurance and not fear for its own sake, just what the research actually shows and what you can realistically do about it.
