| The married got more dementia diagnoses. Not fewer. |
| Start with a result nobody predicted. A team at Florida State University tracked 24,107 older adults, average age 71.8. The records came from the National Alzheimer’s Coordinating Center, which pools files from memory centers across the country. Follow-up ran as long as 18 years. Married people were diagnosed with dementia more often than anyone else. |
| Look at the spread. Never-married adults had about 24% lower odds of a diagnosis. For divorced adults it was 17% lower. Widowed adults looked lower too, until the researchers accounted for age, education, health and low mood. Then that gap closed. The pattern held for Alzheimer’s and for other kinds of dementia. |
| Let me explain what probably happened. Dementia does not announce itself. Someone has to notice. A wife hears the same question twice in an hour. She sees the keys in the freezer, the wrong turn on a road you have driven for 30 years. She books the appointment. Living alone, that same slow slide can go unnamed for years. |
| Think of a spouse as a lookout. The ship drifts either way. The lookout just calls it sooner. |
| |
There is a second reading here. People who never married keep wider circles — friends, neighbors, standing plans. That kind of contact tracks with slower decline. A hard marriage is a stress load. A good one is a second pair of eyes. |
|
| I could be wrong about the balance here. These volunteers came through memory clinics, so they are not a slice of the whole country. The work landed in April 2025 and still needs a test in the general population. I expect the noticing piece to hold up. The rest is open. |
| So use it. Pick one person who would tell you straight. A wife, a brother, an old friend. Then say it out loud: if my memory slips, I want to hear it from you. I urge you to have that conversation this weekend. |

| Drink the water your thirst stopped asking for |
| Thirst gets quieter with age. The signal fades; the need does not. So plenty of men in their sixties walk around a half-quart low and call it a slow afternoon. |
| Start with a small trial. Researchers in the British Journal of Nutrition took 26 healthy men. They dropped their body water by about 1.5%. Nothing dramatic. Attention slipped on a long dull task. Mood slipped with it. In 2024 a group studying middle-aged and older adults found the same soft spot — sustained attention. Memory scores held steady. So treat this as a focus lever, not a memory cure. |
| Which means water works better as a scheduled item than a request. |
| The Protocol |
| When |
| One glass within 20 minutes of waking. One with every meal. One before any stretch of hard thinking. |
| Duration |
| Every day. Judge it after one week. |
| Rules |
| Aim for pale straw, not clear. Coffee counts, but do not lean on it. Front-load the day and ease off two hours before bed. On a water pill, or with heart or kidney trouble, ask your doctor for your own number first. |
| |
| Watch your four o’clock focus. That is where you will feel it first, and it costs you nothing to find out. I urge you to try it for a week. |

| Chasing a sleep score can cost you sleep |
| Sleep doctors gave this one a name. Kelly Baron and colleagues, then at Rush University Medical Center, wrote up an odd set of patients. They slept worse the harder they chased the numbers on a tracker. The doctors called it orthosomnia — losing sleep over your sleep grade. The ring turns rest into a test. The testing keeps you up. It was a short write-up of a few patients, not a trial. But if a bad score sours your morning, drop the device in a drawer for two weeks and watch what happens. |

| One protein carried the benefit of eating less |
| Eating less appears to slow aging. Almost nobody keeps it up. So a Yale School of Medicine group led by Vishwa Deep Dixit went hunting for the go-between. Forty-two people cut 11 to 14% of their calories for two years. One immune protein dropped sharply. It is called complement C3, and it helps drive the slow burn of inflammation. The drop had nothing to do with how much weight anyone lost. Blocking that protein in mice lowered age-related inflammation too. Nobody measured memory here. Still, that slow burn is one of the roads into a foggy brain, and this points at a switch on it. |

| A shark kept its eyes for two centuries |
| Greenland sharks live close to 400 years. Dorota Skowronska-Krawczyk at the University of California, Irvine, worked with colleagues at the University of Basel. They examined eyes from sharks caught off Disko Island, Greenland. One animal was around 200 years old. They found no sign of dying cells in the retina. The light-catching protein still worked, still tuned to Arctic blue. Your retina is brain tissue, pushed out to the front of your head. Something in that shark keeps it intact for centuries. What we could borrow from it, nobody knows yet. |

| Are the new Alzheimer’s drugs worth it? |
| Side A |
| Two drugs now strip out amyloid. That is the sticky protein that piles up in Alzheimer’s. One is lecanemab. A trial put 1,795 people with early disease on it. Decline ran about 27% slower over 18 months. Judith Heidebrink at the University of Michigan says those patients hold on to doing things themselves. Estimates point to perhaps one extra year of that. For a man of 68 with a new diagnosis, that year is the whole argument. And these are the first drugs that touch the disease, not just the symptoms. |
| Side B |
| Then look at the size of it. On the rating scale used, the gap was 0.45 points out of 18. James Burke at Ohio State University doubts a family would notice that. Now the risks. Brain swelling or small bleeds turned up in 17.3% of people on lecanemab, against 9% on placebo. With the second drug, donanemab, the figure ran near 30%. Three deaths were tied to it. Then the price. It runs $26,500 a year for one drug, $32,000 for the other. Add repeat scans and an infusion every two weeks. Burke’s line: the harms are heavy and the benefit may be invisible. |
