Walked into a room and forgot why? Before you panic, listen to this. In this episode of the Over 50 Health & Wellness Podcast, host Mark Sullivan tackles brain health and memory after 50 with honesty and reassurance — separating normal age-related forgetfulness from real warning signs, and sharing what the latest research says you can actually do to protect your mind.

Learn the key difference between normal aging and dementia, the treatable conditions that can masquerade as memory loss, and the 2024 Lancet Commission finding that nearly half of dementia cases may be preventable or delayed. Discover why what's good for your heart is good for your brain. Backed by the NIH, the Lancet Commission, and Rush University research.

In this episode:• Normal forgetfulness vs. real warning signs• Why dementia is NOT a normal part of aging• Treatable causes of memory trouble you might be missing• The 14 risk factors behind ~45% of dementia cases• The MIND diet and brain-protective habits• What a memory evaluation actually involves• 3 simple things you can start this week
