About this study

Official title: Prospective, Randomized, Evaluator-blind, Single Center Study on the Effect of Transcranial Magnetic Stimulation in Mild to Moderate Alzheimer's Disease

The investigators will compare cognitition, mood (depression), ADL, and brain structural and functional MRI before and after 4-week transcranial magnetic stimulation in patients with mild to moderate Alzheimer's disease.

The investigators also compare the change of cognitition, mood (depression), ADL, and brain structural and functional MRI between TMS group and sham coil group.

Read the detailed description

Each 16 patients will be allocated to TMS group and sham coil group. Before TMS/sham coil stimulation, the investigators will take fMRI of each patient, and figure out which focus has strongest connectivity to hippocampus among lateral parietal regions of the brain. The investigators will fix the TSM transduced and apply accurate TMS stimulation to the focus using personalized frames. The investigators will make the frame using 3D printing technology.

After 4 week- TMS stimulation, the investigators will compare cognitition, mood (depression), ADL, and brain structural and functional MRI beween baseline and after intervention. The investigators also compare the change of cognitition, mood (depression), ADL, and brain structural and functional MRI between TMS group and sham coil group.

Being tested
TMS, sham coil stimulation

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TMSDevice

    • stimulation intensity : motor threshold 100%
    • stimulation frequency : 1600 pulses for 20 minutes
    • stimulation duration :for four weaks, 20 minutes/day, 5 days per week (Monday - Friday )
  • sham coil stimulationDevice

Questions about this trial

What is this clinical trial studying?

A study testing TMS in people with Mild to Moderate Alzheimer Disease, run by Samsung Medical Center at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 7 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Young Hee Jung, MD PhD (82-10-6755-5462, neophilia1618@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the short term change of K-MMSE score in TMS group (time frame: 4 weeks). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04260724, which also lists 11 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Feb 2020.
