A recent study showed that newborns have high levels of p-tau, a biomarker for #Alzheimer disease. Understanding how infants clear the protein could help prevent aggregation, which leads to #neurodegeneration in adults. #MedSky #NeuroSky

#AAICNeuro Cameroon Hub: Day Two!

Kickoff of #AAICNeuro in Porto Alegre! 🌎 This week, 12 hubs worldwide will showcase the next generation of Alzheimer’s & dementia researchers and clinicians. Stay tuned for updates throughout the day! @alzassociation.bsky.social @erzimmer.bsky.social #CristianoAguzzoli

#AAICneuro POA Hub just started in our beloved Porto Alegre 🇧🇷! A great pleasure to co-host the event with #CristianoAguzzoli @zimmerneurolab.bsky.social @alzassociation.bsky.social

Despite carrying a genetic mutation associated with early-onset #Alzheimer’s, a man remained free of dementia symptoms for at least 2 decades longer than expected 👉 genetic variants may explain this remarkable resilience. See more here: www.nature.com/articles/d41...

A man was destined for early Alzheimer’s — these genes might explain his escape

Scientists identify nine genetic variants that could have helped a man to avoid dementia for at least two decades longer than expected.
