Effect of Transcranial Alternating Current Stimulation(tACS) for Early Alzheimer's Disease

Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation tool that alters cortical excitability and activity via application of weak alternating currents.

In the sham condition, tACS was delivered only during the ramp-up and ramp-down periods (30s); no current was delivered during the 30-minute intervention.
