Here are facts and fiction behind the "breakthrough" seeding test for #Parkinsons. In this No Silver Bullet 4PD episode, I explain seeding and what a positive seeding test can and can't tell. I end with how patients and advocates can spot hype and push for change. www.youtube.com/watch?v=UpXe...

Beautiful. Michael J Fox receives the Medal of Freedom. So well deserved.

Combining hyposmia + mild DaT abnormalities helpful in picking out folks (early) who will have a potentially positive synuclein seeding assay in the spinal fluid. It will be really nice to continue to track folks. 'Hyposmic individuals with +aSynSAA at high risk for eventual clinical symptoms.'

This article discusses clinical use of biomarker tests for Alzheimer's disease pathology, including indications for testing, review of biomarker modalities (PET, CSF, blood), selection of modality based on individual factors, and interpretation and return of results. #ENDALZ doi.org/10.1002/alz....

I'm so excited to start my reading in 2025 with Immortality by @danaschwartz.bsky.social sequel to the book "Anatomy: a love story", one of the most beautiful novels of love and female improvement in Medicine that I have read, if not the best. But look that cover, with a detailed brain included!🧠💜.

What does a positive αSyn-SAA mean? ✅It supports a Parkinson's diagnosis. ✅It does not indicate disease mechanisms, severity, progression rate, biological subtypes, or treatment response. Important article: www.sciencedirect.com/science/arti... @albertoespay.bsky.social @ajlees.bsky.social

Prevention and health promotion is less known to be practiced in Neurology. However, maintaining this approach transversally in Neuroscience will always be a contribution and valuable contribution for patients and health providers As always, acronyms are useful. #NeuroResolution2025

Today’s Neurology Question (AAN) on Alzheimer’s biomarkers showed that only 57% of neurologists select low CSF Ab42. Might that be the influence of a disease framework where everything “goes up,” with AD resulting from “too much” amyloid?
