About this study

The purpose of this study is to evaluate the safety and effectiveness of transcranial magnetic stimulation (TMS) therapy in moyamoya patients who received surgical revascularization.

Read the detailed description

Primary Outcome Measures:

TMS stimulation applied to the left DLPFC has a quantifiable effect on cognition [ Time Frame: Neuropsychological Assessments: Baseline(7days after STA-MCA bypass surgery); 2 months after TMS treatment Changes in one or more assessed cognitive domains at baseline will be measured by comparing the scores for the different neuropsychological tests.

Secondary Outcome Measures:

Change in structural grey and white matter in the brain at baseline compared to after TMS stimulation [ Time Frame: MRI: Baseline and two months after TMS stimulation ] MRI analysis will measure any changes in cortical thickness (mm) or other structural changes in the brain after TMS or Sham-TMS stimulation

Change in executive functioning measured as resting-state functional MRI (fMRI) sequence [ Time Frame: MRI: Baseline and two months after TMS stimulation ] fMRI analysis will measure any changes in amplitude of low frequency fluctuation(ALFF) and other functional changes after TMS stimulation compared to baseline.

Transcranial Magnetic Stimulation, Sham Transcranial Magnetic Stimulation

What participants receive

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

  • Transcranial Magnetic StimulationDevice

    Also called TMS

    A total of 2000 trains will be delivered successively. The pulses will be delivered at 80% of motor thresholds.

  • Sham Transcranial Magnetic StimulationDevice

    Also called Sham-TMS

    The sham coil looks and sounds just like the real coil, but produces a negligible magnetic field.

Study groups in NCT03543748
Study groupRoleWhat they receive
TMSExperimentalThe Transcranial Magnetic Stimulation course consisted of daily sessions of 2,000 stimuli for the left DLPFC (50 trains of 40 stimuli at 10 Hz for 10 days),
Receives: Device: Transcranial Magnetic Stimulation
SHAMSham comparatorThe patient is treated with Sham-TMS stimulation according to protocol with an inactive coil. The sham coil looks and sounds just like the real coil, but produces a negligible magnetic field.
Receives: Device: Sham Transcranial Magnetic Stimulation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Neurocognitive outcomes at 3 months follow-up after TMS

    Measure neurocognitive outcomes using Mini-mental State Examination (MMSE)

    Measured: 3 months

  2. Neurocognitive outcomes at 3 months follow-up after TMS

    Measure neurocognitive outcomes using memory and executive screening (MES)

    Measured: 3 months

Secondary outcomes (4)
  1. Change in structural imaging in the brain at baseline compared to after TMS stimulation

    MRI analysis will measure any changes in cortical thickness (mm) in the brain after TMS or Sham-TMS stimulation

    Measured: 3 months

  2. Change in structural imaging in the brain at baseline compared to after TMS stimulation

    MRI analysis will measure any changes in cortical white matter micro-structure (DTI) in the brain after TMS or Sham-TMS stimulation

    Measured: 3 months

  3. Change in functional imaging in the brain at baseline compaired to after TMS stimulation

    MRI analysis will measure any changes in ALFF in the brain after TMS or Sham-TMS stimulation

    Measured: 3 month

  4. Change in functional imaging in the brain at baseline compaired to after TMS stimulation

    MRI analysis will measure any changes in functional connectivity strength in the brain after TMS or Sham-TMS stimulation

    Measured: 3 month

Questions about this trial

What is this clinical trial studying?

A study testing Transcranial Magnetic Stimulation in people with Moyamoya Disease, run by Huashan Hospital.

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 7 inclusion and 8 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 1 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Neurocognitive outcomes at 3 months follow-up after TMS (time frame: 3 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Jun 2018.
