Summary

This study tested whether a non-invasive brain stimulation method called tACS could reduce amyloid and tau proteins in people with mild to moderate Alzheimer's. Seventeen participants received daily sessions of tACS or a sham treatment for 2-4 weeks. The goal was to see if the stimulation could safely clear these proteins and improve memory.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
transcranial alternating current stimulation (tACS)
What this could lead to
If it works, this could point toward a non-drug way to slow Alzheimer's by clearing harmful brain proteins.
What could go wrong
This is a very small early-phase trial with only 17 people, so results may not apply broadly. The treatment is still experimental and may not show clear benefit.
