What If You Could Train Your Brain to Forget Less?

from The Habit Healers · host Laurie Marbas, MD, MBA

Is your forgetfulness normal aging, or something more? If you’re over 45 and you’ve walked into a room and forgotten why, or lost someone’s name five seconds after hearing it, this episode is for you.I’m Dr. Laurie Marbas, and on this episode of The Habit Healers Podcast I walk you through how memory actually works inside your brain, and why so much of it is under your control. We start with the patient known as H.M., whose surgery revealed that memory isn’t one system at all but several, running in different parts of the brain. From there I explain how a memory gets built, why sleep is the window where memories get filed for the long term, and how chronic stress and elevated cortisol quietly wear down the hippocampus.Then we get practical. I share the only two study techniques that earned the highest rating in a landmark review of learning research, and why highlighting and rereading rank near the bottom. I give you specific fixes for remembering names, phone numbers, and grocery lists. And I walk through the fourteen modifiable risk factors identified by the Lancet Commission that together account for roughly 45 percent of dementia cases worldwide.What you’ll learn:* Why memory is several separate systems, not one* How sleep consolidates memories and what happens when you lose it* The two highest-rated memory techniques in the research* A step-by-step method for remembering names* The lifestyle habits that protect your brain long term* The red flags that mean it’s time to talk to your doctorDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-you-could-train-your-brainCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
