Deep Repetitive Transcranial Magnetic Stimulation (rTMS) of the Precuneus for Alzheimer Disease (AD)
Sponsor: University of California, Los Angeles
Summary
The goal of this clinical trial is to learn if using deep repetitive transcranial magnetic stimulation (rTMS) targeting the precuneus is feasible, tolerable, and potentially efficacious for memory in Probable Alzheimer's Dementia. Previous work studying rTMS in Alzheimer's is mixed, but recent work studying rTMS of the precuneus is encouraging for both its short-term and long-term effects. The main questions this study aims to answer are: * Is deep rTMS of the precuneus feasible and tolerable in Alzheimer's? * Are there signs of positive brain changes in response to deep rTMS? * Is deep rTMS potentially efficacious for memory in Alzheimer's? Researchers will compare active stimulation to placebo stimulation while obtaining memory testing and measurements of the brain (imaging, scalp electrode measurements, bloodwork) to see if active treatment works to treat mild-to-moderate probable Alzheimer's Dementia. Participants will: * Engage with memory testing, brain scans, and bloodwork during a comprehensive assessment * Visit the clinic 3 times for 12 consolidated rTMS sessions, followed by 4 once weekly maintenance sessions * Be offered a full open-label active treatment course after completing their treatment course if they are initially in the placebo group

Interventions
TMS
rTMS Stimulation Parameters Pulse count: 1600 pulses Frequency: 20Hz Pules per train: 40 pulses Inter-train interval: 28 seconds Intensity: 100% Motor Threshold (depth-corrected from MRI) Target: Precuneus using structural MRI navigation with MNI coordinates
Transcranial Magnetic Stimulation Sham
Sham coil placed in same location and set with same parameters as active treatment coil. However, this device will not output active treatment and scalp electrodes will mimic the sensation of rTMS for the participant.
