Tau PET tracks Alzheimer’s disease better than amyloid PET, but tracking disease is not the same as proving what will rescue the brain.

Biggest news out of the AAIC meeting? We can celebrate even modest successes, but here the caveats vastly outweigh them: small effect size; weird results at highest doses; still only Phase II. Maybe keep your champagne on ice, but don't pop any corks yet. www.science.org/content/arti...

www.nature.com/articles/s41... Just finished this excellent review by @erictopol.bsky.social and Wyss-Coray. The authors emphasize how discordant the aging of each organ is, but I am struck instead by how similar the time lines are.

I finally commented on the proposed OMB rule change (through the #StandUpForScience portal). I emphasized the economic and security damage that will be done. I figured the damage to science will be well covered by others. Doubt that anyone in power will read it, but I know I did the right thing

I only have one Bluesky account so I mix science and politics. I read politics, but try to only post science (a blurry dividing line these days). Today, science news: as of July 1st I am officially Professor Emeritus. It's been a great run. But don't worry; I'm not done commenting or writing.

This is the thing that so many Americans don’t seem to grasp: private companies are in it to make a profit, and nothing else. There are so many important, necessary discoveries that industry will never look into simply because they can’t make enough money on it.

Pittsburgh symphony did a powerful All-American concert yesterday, ending with Copland’s 1942 “Lincoln Portrait”. The words were Lincoln’s, but the resonance of their message with today was almost unbearable. Especially coming on the day of the abomination on the South Lawn of the White House.

It’s worse than that. The new therapies are half as effective as safe cholinesterase inhibitors and cost 100 times more. The companies won’t release their data so true estimates of risk are hard to know. The blitz of TV ads are essential to them because this is marketing not medicine.

Note to Program Committee: moved the poster from RR7 to D40. I know. I know. Patently illegal. But it was an empty board even 90 minutes into the morning. So no harm. Within minutes, traffic increased 10x (and I must say, it was really well received). Thanks to all who dropped by.

Dollars to donuts those parts were “written” by ChatGPT. I had exactly that experience with the program. Since I verified everything first, it makes for a funny story (& a cautionary tale), but it might not be great way to write a MAHA report.

pubmed.ncbi.nlm.nih.gov/40110649/ I love how this abstract puts a reverse spin on the results. They conclude that cognitive decline does not predict amyloid deposition. For me the data is really telling us that amyloid does not drive cognitive decline. Did I miss something? #alzheimers #amyloid
