| The brain-health recipe works — and a little structure makes it work better |
| The proof keeps getting stronger. I believe this week’s big trial is the clearest yet. Researchers in London shared a two-year study called LatAm–FINGERS. It ran across 11 countries in Latin America. Every person in it was an older adult at some risk of memory decline. |
| The idea was plain. Give people the habits that guard the brain, and see if thinking holds up. Those habits were exercise, healthy eating, mental workouts, and time with others. Everyone got the same five targets. |
| Let me explain the twist. One group followed a structured plan — set sessions, a team, and a coach checking in. The other group got the same advice but ran it on their own. Both improved. The structured group improved far more. |
| |
On a broad test of thinking, the coached group gained 55% more than the do-it-yourself group. The recipe was the same — the difference was structure and support. |
|
| The coached group also did better on memory, planning, and speed of thought. Think of it like a gym. You can work out alone, and it helps. Work out with a trainer and a schedule, and you go further. |
| This was two years, not twenty, and I could be wrong about how long the gains last. The people also knew what they were doing, which can flatter results. Still, the direction is clear, and it fits everything else we know. |
| You don’t need a clinic to copy this. Pick the five targets. Then add a little structure — a set time, a class, a friend who keeps you honest. I urge you to build the scaffold, not just the wish. |

| Take up dancing — it trains the body and the brain at once |
| One habit hits several brain targets at once. It’s dancing. It moves your body and makes your mind work at the same time. |
| You have to learn steps. You track the beat. You hold a pattern in mind, then change it. That mix — movement plus memory plus timing — is exactly what an aging brain needs. |
| Brain scans show why it helps. In older adults, regular dance classes raised the volume of the hippocampus — the brain’s main memory hub. One study saw stronger wiring in a memory pathway called the fornix, the cable that runs in and out of that hub. Plain walking is great. Dancing asks a bit more of your head. |
| You don’t need to be good at it. You just need to keep learning new moves. So here is a simple way to start. |
| The Protocol |
| When |
| 2 to 3 times a week. Any style with steps to learn — ballroom, line dancing, salsa, swing. |
| Duration |
| 30 to 45 minutes a session. Give it 3 months before you judge it. |
| Rules |
| Pick routines you don’t know yet. Learn with a partner or a class for the company. Move enough to breathe harder, but stay safe on your feet. |
| |
| Watch for the fun. If you enjoy it, you’ll keep showing up — and that’s what counts. I urge you to try it, even if you feel silly at first. |

| Years of heading a soccer ball may leave a mark on the brain |
| Repeated hits to the head add up. At the London meeting, researchers shared brain scans of former elite soccer players. Compared with people who hadn’t taken those knocks, some players showed differences in brain structure. They also reported more depression, more anxiety, and more trouble with thinking and decisions. This doesn’t prove the headers caused it. But it adds to the worry about sport and repeated blows to the head. |

| Where you live shapes your dementia risk — but you still hold levers |
| Place matters more than you’d think. A study of more than 214,000 older adults spanned 14 countries. The top risks shifted a lot from one place to the next. Low education, high blood pressure, and smoking each weighed more in some countries than others. But the same risks tended to travel together everywhere. The lead scientist put it plainly: your risk isn’t fixed, and your daily choices still move it. |

| Treating heart risks may protect memory too |
| Your heart pills may do double duty. In a study of more than 4,500 older adults, those taking a mix of drugs for blood pressure, cholesterol, and blood sugar declined more slowly on thinking tests. Their scores looked like people about three years younger. What helps the heart keeps helping the brain. If you take these already, it’s one more reason to stay the course with your doctor. |

| London is hosting the year’s biggest dementia meeting. It runs July 12 to 15. Right now, 158 treatments sit in human trials. For years, almost all of them chased the same two targets — the sticky plaques and tangled fibers found in Alzheimer’s brains. Now three of every four look elsewhere. Here are three worth watching. |

| A pill that calms the brain’s overactive defense cells |
| Your brain has its own cleanup and defense crew — cells called microglia. In Alzheimer’s they can get stuck in attack mode and fuel the damage. NTRX-07, from NeuroTherapia, is a once-a-day pill that flips a switch on those cells to calm them down. In a small early trial it looked safe, and a blood marker of brain-cell breakdown held steady while it rose in the placebo group. The company is showing the data in London and moving to a larger test. |

| A big trial pairs a healthy-living program with a weight-loss shot |
| This one is a trial, not a drug. The Alzheimer’s Association just launched PROTECT–Cog, a $100 million global study. It tests whether a proven healthy-living program works even better alongside one of the new weight-loss and diabetes shots — the same family as Ozempic and Wegovy. The aim is to see if the pair cuts the risk of memory loss in older adults at risk. It’s the first big test of lifestyle and one of these drugs together. |

| A tau-lowering drug we flagged in June — first trial results are in |
| Back in late June we noted a Biogen drug aimed at tau — the protein that tangles inside brain cells. It now has a name: diranersen. It works like a set of instructions telling cells to make less tau. Its mid-stage trial just missed its main goal. But tau dropped at every dose, and thinking declined a bit more slowly — enough that Biogen plans to push toward a final-stage trial. A near-miss with real signals still teaches us plenty. |
