| A Brain Game Nudged a Real Alzheimer’s Marker |
| Brain games usually just raise test scores. This one did more. It moved a marker of Alzheimer’s inside the blood. That has rarely happened before. |
| The results came this week from the Alzheimer’s Association International Conference in London. Scientists split 53 older adults into two groups. One did 20 hours of speed training on a brain app called BrainHQ. The other played ordinary computer games, like word search. |
| Let me explain what they tracked. Amyloid is a sticky protein that clumps up in Alzheimer’s. The blood holds clues about how it is building. After the speed training, that picture looked healthier. The plain games did not shift it. |

A mental drill, not a drug, moved a biological marker of Alzheimer’s. That is what makes this one worth watching. |
|
| Think of it like exercise for the wiring. Push the brain to work faster, and the machinery seems to run cleaner. I could be wrong, of course. This was small — 53 people, a short run, one marker, not memory itself. Men and women also responded differently. And the app came from the same company behind the study. |
| Still, I expect training like this to count for more each year. You don’t need their app to begin. Any fast, focused task will do. I urge you to give your brain a few quick minutes today. |

| The 20-Minute Nature Pill |
| Stress wears on the brain. Cortisol is the main stress hormone. Keep it high for years, and it can shrink the hippocampus — your memory hub. So calming it down guards more than your mood. |
| There is a simple fix with real numbers behind it. In a 2019 Frontiers in Psychology study, people spent time in nature while researchers measured the stress hormone in their saliva. Twenty minutes was enough. Cortisol dropped fastest between 20 and 30 minutes outdoors. |
| So treat green time like a daily dose. |
| The Protocol |
| When |
| Most days — any daylight hour works. |
| Duration |
| 20 minutes, and up to 30 is better. |
| Rules |
| Find real green — a park, some trees, your own backyard. Sit or stroll, your choice. Leave the phone in your pocket. No earbuds, no calls. |
| |
| You should feel calmer inside the first week. It costs nothing. I urge you to try it three times before Sunday. |

| The Alzheimer’s Drug May Come Home |
| Today, the new Alzheimer’s drug means clinic trips. That may change. New data this week showed lecanemab — an approved treatment for early Alzheimer’s — works about as well as a shot you give at home as it does through the usual vein drip. A large real-world review, three years in, backed once-a-month upkeep too. For people already diagnosed, that means far less time hooked to a line. |

| Tau Isn’t Only a Villain |
| Tau is famous as the tangle protein. You know it from Alzheimer’s. But it turns out tau has a day job. In mice, it helps sort which brain cells hold a fresh memory, so that memory stays clear and steady. Wipe tau out completely and memories may blur. So future drugs may need to dial it down, not erase it. |

| Your Blood-Pressure Cuff May Warn You |
| Your cuff may say more than two numbers. At the London conference, researchers found that patterns in routine blood-pressure readings — not just the high and low — can help flag who faces higher dementia risk. It’s an early signal, not a diagnosis. Still, it’s a free reason to track your pressure and keep it steady. |

| Lion’s Mane Mushroom |
| Fans call it nature’s nerve tonic. In the lab, lion’s mane raises nerve growth factor — a signal that helps brain cells grow and repair. A 2025 trial in Frontiers in Nutrition saw a quick rise in attention and mood in young adults. A small 16-week study in older adults with mild memory loss saw scores improve. |
| But the wins are thin. That memory gain faded once people stopped taking it. Most trials are small, short, and run in young or tiny groups. No big, long study in older adults exists yet. And products vary wildly — many hold little of the real mushroom extract. |
| Verdict: Low risk, low cost — fine to try for a few months, but don’t lean on it alone. Buy a fruiting-body extract from a brand that shows its lab testing. |
