Timeline

Screening 3 weeks

Treatment Varies

Follow Up enrollment to end of 5 weeks of treatment

Summary

This trial aims to see if using deep repetitive transcranial magnetic stimulation (rTMS) on a specific part of the brain can help improve memory in individuals with Probable Alzheimer's Dementia.

Who is the study for?

This trial is for individuals with mild-to-moderate probable Alzheimer's Dementia. Participants will undergo memory testing, brain scans, and bloodwork. They must be able to visit the clinic for multiple rTMS sessions.

What is being tested?

The study tests if deep repetitive transcranial magnetic stimulation (rTMS) targeting the precuneus can improve memory in Alzheimer's patients. It compares active stimulation with placebo while monitoring brain changes through various assessments.

What are the potential side effects?

While not explicitly listed, common side effects of rTMS may include headache, scalp discomfort at the site of stimulation, tingling or spasms of facial muscles, lightheadedness.

Experimental Treatment

Placebo Group

Group I: Randomized Active deep precuneus rTMSExperimental Treatment1 Intervention

The second stage of the study will consist of both active and sham treatment groups. Treatment will consist of 16 sessions of deep rTMS spread over 5 weeks. The induction phase of treatment will be 4 sessions per day for 3 consecutive days (with 60 minutes between sessions), followed by 1 session per week for 4 weeks. Individual sessions will consist of 1600 pulses of 20Hz rTMS delivered in 40 pulse trains to the precuneus (using MRI structural neuronavigation) at 100% of depth-corrected motor-threshold with a 28 second intertrain interval (roughly 20 minutes per session). The active group will receive this protocol using an active treatment coil delivering real rTMS.

Group II: Open-Label Active deep rTMSExperimental Treatment1 Intervention

The first stage of the study will consist of protocol refinement. In this first stage of 5-10 participants, all participants will receive open-label active treatment. Treatment will consist of 16 sessions of deep rTMS spread over 5 weeks. The induction phase of treatment will be 4 sessions per day for 3 consecutive days (with 60 minutes between sessions), followed by 1 session per week for 4 weeks. Individual sessions will consist of 1600 pulses of 20Hz rTMS delivered in 40 pulse trains to the precuneus (using MRI structural neuronavigation) at 100% of depth-corrected motor-threshold with a 28 second intertrain interval (roughly 20 minutes per session).

Group III: Randomized Sham deep precuneus rTMSPlacebo Group2 Interventions

The second stage of the study will consist of both active and sham treatment groups. Treatment will consist of 16 sessions of deep rTMS spread over 5 weeks. The induction phase of treatment will be 4 sessions per day for 3 consecutive days (with 60 minutes between sessions), followed by 1 session per week for 4 weeks. Individual sessions will consist of 1600 pulses of 20Hz rTMS delivered in 40 pulse trains to the precuneus (using MRI structural neuronavigation) at 100% of depth-corrected motor-threshold with a 28 second intertrain interval (roughly 20 minutes per session). The placebo group will receive this protocol using a sham TMS coil delivering inactive rTMS. Participants in the sham/placebo group will be offered a full open-label extension treatment course of active rTMS on completion of the randomized phase.
