UVA Researchers Discover Key to Alzheimer’s Memory Loss

11/21/2025

Summary

Story summary

University of Virginia (UVA) researchers identify perineuronal nets as central to Alzheimer's, instead of amyloid plaques.
The team shows matrix metalloproteinase inhibitors, drugs already in trials, can protect these nets and preserve memory in mice.
Researchers are exploring how immune responses and RNA interactions contribute to memory loss.
Human trials remain years away, but existing drug candidates could speed development for the 55 million people with Alzheimer's.
