Advantage of Cerebellar Transcranial Magnetic Stimulation in Alzheimer's Diseases （ACT-AD）
This trial tests whether a non-invasive brain stimulation technique called intermittent theta-burst stimulation, aimed at the cerebellum, can slow cognitive decline in people with mild Alzheimer's disease. Researchers will measure changes on a standard dementia rating scale over three months. Phase NA here means this is a clinical study focused on device effectiveness and safety, not a traditional drug trial — it has not yet been proven or approved.
