Summary

Story summary

Spanish and Chinese researchers report nanoparticles under 200 nanometers reverse Alzheimer's in mice by restoring blood-brain barrier.
Particles clear amyloid-beta, a toxic protein linked to Alzheimer's.
In mice, amyloid-beta fell 50-60% within an hour; cognitive gains appeared over six months.
Researchers plan human trials in coming years, pending safety studies; findings were published in Signal Transduction and Targeted Therapy.
