| Your voice may be keeping time on your brain |
| Listen to how you talk. A team led by Professor Agustin Ibanez at Trinity College Dublin recorded 2,928 Spanish speakers. They came from Argentina, Chile, Colombia, Mexico and Peru. Some were healthy. Some had mild memory trouble. Others had Alzheimer’s, or a dementia that starts in the front of the brain. |
| Let me explain what the computer did. It studied hundreds of small things in each voice. Speed. Pauses. Pitch. Mood. How exact the word choices were. From those clues it guessed each person’s age. Then the team checked the guess against the real birthday. They call the difference the speech age gap. |
| Healthy people had the smallest gaps. The gaps grew in both kinds of dementia. In Alzheimer’s, a wider gap tracked with a tangle-protein marker in the blood. The gap also lined up with brain scans and with aging clocks read from DNA. Think of your voice as a dashboard light. It won’t name the broken part. It just tells you the engine is working harder. |
| |
Hard years showed up in the voice too. Less schooling, money trouble, skipped meals and poor access to doctors all tracked with older-sounding speech. The life you’ve lived seems to leave a mark on how you talk. |
|
| This was one snapshot, not years of follow-up. Ibanez says plainly it is not a dementia test yet. It still needs checks in other languages and over time. I could be wrong about how useful it turns out to be. But I believe a cheap voice check could one day sit beside the blood test. |
| Until then, use the ears around you. Maybe someone close says you lose words more. Maybe they notice longer pauses. Take that seriously. I urge you to mention it at your next checkup. |

| Soak the apples before you eat the skin |
| In July I said rinse your produce. Rinsing does less than you’d think. Farm sprays have come up here twice this year. A UCLA team tied one bug spray to double the Parkinson’s risk. A South Carolina team found Alzheimer’s rates rising where farm chemicals were heaviest. |
| So how do you get the spray off? Food chemist Lili He at the University of Massachusetts Amherst tested it on apples. She used two common sprays, one for mold and one for bugs. Tap water did little. A two-minute bleach wash, the industry standard, did little too. A plain baking soda bath worked best. After 12 to 15 minutes, it lifted 80% of one spray from the surface and 96% of the other. |
| It costs pennies. Here is the routine. |
| The Protocol |
| When |
| Before you eat any fruit with the skin on — apples, pears, peaches, grapes |
| Duration |
| 12 to 15 minutes in the bath. Two minutes does almost nothing. |
| Rules |
| Stir one teaspoon of baking soda into two cups of water. Keep the fruit fully under. Rinse with clean water and dry it. Peel what you can’t soak. |
| |
| No wash reaches spray that has soaked under the skin. And the levels on most fruit sit inside federal safety limits. So treat this as a cheap margin, not a reason to fear fruit. Keep eating plenty of it. I urge you to try it with this week’s apples. |

| Hearing aids finally got a real trial |
| We’ve covered the records studies before. This one was a true test. Doctors in China enrolled 703 people, average age 75, with hearing loss and mild memory trouble. Half got two hearing aids. Half got classes on hearing care. After two years, a few fewer aid users had slipped into dementia. That gap was too small to count. The bigger change ran the other way. About 1 in 7 aid users tested normal again, against about 1 in 40 in the class group. If you’ve put off a hearing test, book it. |

| A run-down body tracked with a slipping mind — in men |
| Frailty means slow, weak and worn out. Researchers at the University of Colorado followed nearly 1,400 adults with mild to moderate kidney disease. Frail men had more than double the risk of new thinking problems. In women, frailty showed no such link, even though more women were frail. The team can’t explain the split yet. But frailty is quick to spot in a clinic. So it may flag the men who need help early. |

| Creatine added muscle even without a workout |
| Here’s an update on an August topic. Richard Kreider’s lab at Texas A&M gave 64 adults aged 45 to 65 creatine or a dummy powder. The test ran 12 weeks. The non-exercisers on creatine still added about 2.4 pounds of lean tissue. Their leg and bench strength rose too. Those who also trained gained more and lost fat. The dose was 10 grams a day, about double the usual scoop. Thinking tests were run, but those results aren’t out yet. If your kidneys are an issue, ask your doctor first. |

| Three brain medicines moved last week. Each sits a different distance from your pharmacy shelf. One arrives this month. One is in the regulators’ fast review line. One just earned its way into final trials. And not one of them is a memory drug. |

| A new kind of dopamine pill for Parkinson’s is approved |
| Parkinson’s drains the brain’s dopamine. That chemical keeps movement smooth. American regulators have now approved AbbVie’s tavapadon, sold as Juvmo. It’s one pill a day. It works on a different pair of dopamine docking spots than older pills do. That may mean less daytime sleepiness. In one trial, people added it to their usual medicine. They gained 1.7 hours a day of good control, against 0.6 hours on a dummy pill. Nausea and headache were the common side effects. |

| Calming the immune attack inside the brain in multiple sclerosis |
| Multiple sclerosis strips the insulation off nerves. The body’s own immune system does the stripping. Roche’s fenebrutinib is a twice-daily pill that crosses into the brain. It blocks an enzyme that switches immune cells on. In two trials against an older pill, it cut relapses by 51% and 59%. In the slow, steadily worsening form of the disease, it held level with a leading infusion. Liver numbers rose in some people, so it would need blood checks. Regulators accepted the file on September 30. |

| Quieting the hallucinations that can come with Alzheimer’s |
| Some Alzheimer’s patients see things that aren’t there. Others believe things that aren’t true. Families call it one of the hardest parts. Acadia’s remlifanserin quiets one docking spot for serotonin, a brain messenger tied to how we perceive the world. In a six-week trial, the higher dose narrowly missed its main goal. But doctors rated patients clearly less ill overall. The lower dose did little, so it’s been dropped. Two final-stage trials are already enrolling. |
