About this study

Official title: The Effectiveness of Individualized Transcranial Electrical Stimulation in Improving Cognitive Impairment in Patients With Central Nervous System Inflammatory Demyelinating Diseases

Background: Central nervous system inflammatory demyelinating diseases often lead to significant cognitive impairment, presenting a critical challenge in patient management.

Objective: To evaluate the effectiveness of individualized transcranial electrical stimulation (tES) in improving cognitive function among patients with inflammatory demyelinating disorders.

Methods: This study will assess cognitive performance through standardized neuropsychological assessments before and after individualized tES intervention, measuring changes in cognitive domains including memory, attention, executive function, and processing speed.

Anticipated Results: the investigators hypothesize that personalized transcranial electrical stimulation will demonstrate significant improvements in cognitive performance, potentially offering a non-invasive therapeutic approach for managing cognitive decline in central nervous system inflammatory demyelinating diseases.

Significance: This research may provide novel insights into neuromodulation strategies for cognitive rehabilitation in patients with complex neurological conditions.

What participants receive

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

  • tESDevice

    his study employs a randomized controlled trial (RCT) design, randomly dividing eligible participants into a neuromodulation group and a sham neuromodulation group.

    Neuromodulation Group:

    Receive individualized transcranial electrical stimulation (tES) treatment Combined with cognitive training

    Stimulation parameters:

    Total current: approximately 2mA Duration: 21 minutes Electroencephalogram (EEG) and multimodal MRI monitoring before and after electrical stimulation

  • tESDevice

    Use the same device and procedure as the neuromodulation group Stimulation device automatically turns off after 30 seconds Maintain device connection Design creates similar initial sensations to actual stimulation Maintains the double-blind nature of the study

What is being measured

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

  1. Change in Auditory Verbal Learning Test (AVLT) Score

    The Auditory Verbal Learning Test (AVLT) evaluates verbal learning and memory performance. The AVLT consists of multiple components, including immediate recall, delayed recall, and recognition memory. The immediate recall score is obtained from three consecutive learning trials and ranges from 0 to 36. The 5-minute delayed recall score ranges from 0 to 12, and the 20-minute delayed recall score ranges from 0 to 12. The recognition score ranges from 0 to 24 after interference trials. Higher scores indicate better cognitive performance.

    Measured: Day 1 (baseline), Day 6 (immediately post-treatment), and Day 36 (30-day post-treatment follow-up).

Secondary outcomes (8)
  1. Change in Symbol Digit Modalities Test (SDMT) Score

    The Symbol Digit Modalities Test (SDMT) assesses information processing speed. The SDMT score ranges from 0 to 110, with higher scores indicating better cognitive performance.

    Measured: Day 1 (baseline), Day 6 (immediately post-treatment), and Day 36 (30-day post-treatment follow-up).

  2. Change in EEG Power Spectral Density

    Changes in EEG power spectral density (PSD) will be assessed across delta, theta, alpha, beta, and gamma frequency bands. PSD values will be calculated using spectral analysis and expressed in decibels (dB) after logarithmic transformation. Higher or lower PSD values indicate changes in oscillatory brain activity, and the direction of change will be evaluated statistically.

    Measured: Day 1 (baseline), Day 6 (immediately post-treatment), and Day 36 (30-day post-treatment follow-up).

  3. Change in Resting-State Functional MRI Network Connectivity

    Changes in resting-state functional connectivity between the dorsolateral prefrontal cortex (DLPFC) and other brain regions will be evaluated using resting-state functional MRI to characterize changes in functional interactions associated with the stimulation target.

    Measured: Day 1 (baseline), Day 6 (immediately post-treatment), and Day 36 (30-day post-treatment follow-up).

  4. Change in Fractional Anisotropy (FA)

    Changes in fractional anisotropy (FA), a diffusion tensor imaging metric reflecting white matter microstructural integrity, will be assessed before and after treatment.

    Measured: Day 1 (baseline), Day 6 (immediately post-treatment), and Day 36 (30-day post-treatment follow-up).

  5. Change in EEG Functional Connectivity

    Changes in EEG functional connectivity between the dorsolateral prefrontal cortex (DLPFC) and other brain regions will be evaluated across different frequency bands, including delta, theta, alpha, beta, and gamma bands.

    Measured: Day 1 (baseline), Day 6 (immediately post-treatment), and Day 36 (30-day post-treatment follow-up).

  6. Change in Mean Diffusivity (MD)

    Changes in mean diffusivity (MD), a diffusion tensor imaging metric reflecting overall water diffusion within white matter tissue, will be assessed before and after treatment.

    Measured: Day 1 (baseline), Day 6 (immediately post-treatment), and Day 36 (30-day post-treatment follow-up).

  7. Change in Axial Diffusivity (AD)

    Changes in axial diffusivity (AD), a diffusion tensor imaging metric reflecting diffusion along the principal fiber direction, will be assessed before and after treatment.

    Measured: Day 1 (baseline), Day 6 (immediately post-treatment), and Day 36 (30-day post-treatment follow-up).

  8. Change in Radial Diffusivity (RD)

    Changes in radial diffusivity (RD), a diffusion tensor imaging metric reflecting diffusion perpendicular to the principal fiber direction, will be assessed before and after treatment.

    Measured: Day 1 (baseline), Day 6 (immediately post-treatment), and Day 36 (30-day post-treatment follow-up).
