Summary

Story summary

Researchers developed a nanoparticle method to clear amyloid-beta plaques in mice, achieving a 45% reduction after three injections and improved cognitive function for at least six months.
The approach targets repairing the blood-brain barrier, not just crossing it, as a potential key to treating Alzheimer's disease.
Limitations include a small sample size and the use of genetically modified mice, which may affect generalizability.
