Good morning! The human brain can generate consciousness, store decades of knowledge, and somehow still blank on why we came upstairs. The 27th annual US Memory Championship reminds us that much of its potential may still be untapped. Here are past champions who make Will Hunting look like he forgot where he parked:

Alex Mullen: Memorized the order of a shuffled deck of cards in 18.7 seconds.
Nelson Dellis: Learned 235 names and faces in 15 minutes.
Katherine He: Reproduced a 50-line unpublished poem after 15 minutes of study.

These “memory athletes” rely less on photographic memory than on training: retrieval practice, spaced repetition, sleep, and vivid associations. For their efforts, winners receive a glass seahorse trophy (a nod to the shape of the hippocampus), bragging rights, and the burden of never again being allowed to forget a birthday.

This year’s qualifying round took place July 18; you can watch the 12 finalists compete for the national title on August 29. The rest of us will continue relying on sticky notes.

Can Plant Diversity Beat Probiotics?

GI Gist

You’re probably fielding “Should I take a probiotic?” nearly as often as pickleball injuries walk through the door. A new study suggests the gut health conversation may need to start one step earlier: with what patients are feeding the microbes they already have.

Not what Big Probiotic was hoping for

In a randomized trial, researchers assigned 349 healthy adults with low-fiber diets to six weeks of a 30+ ingredient whole-plant blend rich in fiber, (poly)phenols, and micronutrients; a daily capsule containing Lacticaseibacillus rhamnosus GG (15 billion CFU); or control croutons. The plant blend produced far broader microbiome changes, with 57 bacterial species changing in relative abundance compared with 14 in the control group and just four with probiotics. Participants in the plant group also reported modest improvements in gastrointestinal symptoms, stool consistency, energy, and overall well-being. Those microbiome changes, however, translated into few objective metabolic benefits, with no meaningful changes in glucose or other cardiometabolic biomarkers.

Early returns

The trial came from ZOE, the company behind the 30+ plant blend, and used the company’s Microbiome Health Ranking as its primary outcome—not disqualifying, but a strong case for independent replication. With only six weeks of follow-up and limited objective metabolic benefits, these findings are promising, but preliminary.

Key takeaways

When a patient asks about taking a probiotic, this study points to putting diet before supplements. Think range over routine: more variety in vegetables, legumes, whole grains, nuts, and other plant foods rather than the same few “healthy” staples every day. It probably won’t transform a lipid panel, but it may make the GI review of systems a bit less eventful.

The Implementation Gap in Dementia Prevention

Neuro News

The difference between Blockbuster and Netflix was never the movies. It was how they reached people. A recent study suggests dementia prevention may suffer from a similar blind spot: lifestyle changes are only part of the treatment. The way they’re delivered may be just as consequential.

Same advice, different delivery

To test that idea, investigators randomly assigned 1,065 older adults at elevated dementia risk across 11 Latin American countries to one of two lifestyle programs. One group received an intensive, coach-led lifestyle program that combined supervised exercise, a culturally adapted MIND diet, computerized cognitive training, vascular risk management, and 38 group sessions over two years. The other received periodic health education and general lifestyle guidance through just four group sessions. After two years, the structured program produced a 55% greater relative improvement on the global cognitive composite, along with significantly greater gains in memory, executive function, and processing speed.

As always, a few caveats

The trial included no true usual-care control group, so we don’t know how either intervention compares with simply aging. It also bundled coaching, accountability, social support, exercise, diet, and vascular care into one package, making it impossible to crown an MVP. Finally, whether those cognitive gains ultimately forestall dementia remains to be seen.

Key takeaways

Lifestyle medicine may have entered its implementation era. The next advance may not come from discovering better interventions, but from delivering familiar ones in ways that patients can realistically sustain. When available, steer patients toward structured, group-based, or coach-led programs—through YMCAs, community centers, or memory wellness programs. If those resources don’t exist, consider building accountability into follow-up visits. In other words, “see handout” may not be enough anymore.

Goldilocks and Blood Pressure: Is 130-139 mm Hg “Just Right” in Real-World Practice?

Special Contributor—Frank Domino, MD

What is the ideal range of blood pressure (BP) for lowering my favorite end point: all-cause mortality? The American College of Cardiology (ACC) defines “normal” BP as <120/80 mm Hg. But is this “normal” range associated with the lowest mortality? Let’s look at what new real-world data show.

A 2026 observational study of US veterans provides compelling real-world, evidence-based data. Records of approximately 2.4 million veterans were reviewed based on diagnostic codes, ≥2 office BP readings ≥130/90 mm Hg, or BP medication use. The cohort was 94% male (although it included >160,000 women) and 71% White, with a mean age of 66 years. Thirty-six percent had diabetes, 22% had known cardiovascular disease (CVD), and 19% had chronic kidney disease. The authors adjusted for all the usual confounders and followed patients for all-cause mortality. Here is what they found:

Mortality was lowest for patients with a systolic blood pressure (SBP) of 130-139 mm Hg (aHR=0.83) and with or without CVD. For men and women alike, the lowest all-cause mortality was associated with an SBP of 130-139 mm Hg. For those with an estimated glomerular filtration rate (eGFR) >60 mL/min/1.73 m² or between 30-59 mL/min/1.73 m², the lowest mortality was associated with an SBP of 130-139 mm Hg. For those with an eGFR below 30 mL/min/1.73 m², the lowest mortality was associated with an SBP of 140-149 mm Hg!

And remember that the ACC defines “normal” SBP as <120 mm Hg? This study’s authors found a routine office SBP of <119 mm Hg was associated with higher mortality.

Importantly, this was an observational study of predominantly older male veterans, so it demonstrates an association rather than proves that targeting an SBP of 130-139 mm Hg lowers mortality. Still, it provides compelling real-world evidence that complements randomized clinical trials.

Goldilocks may have been right after all—not too high, not too low, but “just right.” At least in this cohort, that “just right” range appeared to be 130-139 mm Hg.
