It’s becoming increasingly clear that more than 50% of dementia and late-onset Alzheimer’s cases are preventable. One of the best ways to reduce your risk is to keep your senses strong. In this clip, Dr. Tommy Wood (@DrRagnar) and I dive into how sensory loss—whether it’s vision, hearing, or smell—can increase your risk of dementia. But here’s the good news: Getting treatment for sensory issues like cataracts or hearing loss can reverse that risk. If you’re starting to notice any decline in your senses, don’t wait—address it immediately. Hearing aids, cataract surgery, and other treatments can help maintain crucial brain connections and protect against cognitive decline. Beyond that, train your balance and other sensory systems. Run outside (trail run!), ride a bike, play ball sports, and find other ways to challenge your senses. These activities offer benefits in a way the gym simply cannot. Take action to keep your senses sharp now, and your brain will thank you later.
