About this study

Official title: A Randomized, Controlled Clinical Study on Cerebellar ITBS Mode Transcranial Magnetic Stimulation for the Treatment of Alzheimer's Disease

Study the therapeutic effect and potential neural mechanisms of cerebellar iTBS mode transcranial magnetic stimulation on Alzheimer's disease patients through MRI and EEG.

Read the detailed description

This study intends to apply intermittent therapy for the first time θ The Outbreak Stimulation (iTBS) mode was used for rTMS treatment in the cerebellum of Alzheimer's disease (AD). This was a randomized, double-blind, parallel, and sham stimulation controlled clinical trial, which included 28 AD patients. All patients were randomly divided into the iTBS group and the sham stimulation group. Collect clinical information, scales, magnetic resonance imaging, TMS synchronous electroencephalography, polysomnography monitoring, etc., and then perform TMS/false stimulation treatment on subjects for 4 weeks (a total of 20 times); After treatment and one month follow-up, relevant scales, magnetic resonance imaging, TMS synchronous electroencephalogram and other data were collected again, and appropriate statistical methods were used to analyze the therapeutic effect.

What is being measured

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

  1. The changes in CDR(Clinical Dementia Rating)

    The changes in CDR-SB will constitute the major research outcome measure used to assess response to rTMS.There are two scoring methods for the CDR scale, namely Total Score Calculation (CDR-GS) and Sum of Six Content Calculation (CDR-SB). The scoring method used in this study is CDR-SB, with a total score of 18 points. The lower the score, the milder the symptoms

    Measured: baseline, 4 weeks after start of the treatment

Secondary outcomes (9)
  1. The changes in MMSE(Mini Mental State Examination)

    The changes in MMSE will constitute the secondary research outcome.The full name of MMSE is mini-mental state examination. The higher the score, the better. In this study, changes in MMSE scores before and after treatment were used as secondary observations.

    Measured: baseline, 4 weeks and 4 weeks after treatment

  2. NPI (Neuropsychiatric Inventory)

    The changes in NPI will constitute the secondary research outcome. The Neuropsychology Scale (NPI) evaluates 12 neuropsychiatric disorders which included 10 neuropsychiatric symptoms and 2 autonomic neurological symptoms based on the caregiver's perception of the patient's behavior and the perceived distress. The lower the score, the lighter the symptoms.

    Measured: baseline, 4 weeks and 4 weeks after treatment

  3. ADL( Lawton-Brody Activities of Daily Living)

    The changes in ADL will constitute the secondary research outcome. The ADL evaluates 20 items activities of daily living which included basic life ability and instrument use ability based on the caregiver's perception of the patient's behavior. The lower the score, the lighter the symptoms.

    Measured: baseline, 4 weeks and 4 weeks after treatment

  4. DST (Digital Span Test; Forward and Backward)

    The changes in DST will constitute the secondary research outcome. Digital span test (DST) was commonly used to evaluate attention ability and instantaneous memory ability.

    Measured: baseline, 4 weeks and 4 weeks after treatment

  5. ADAS-cog(Alzheimer's disease assessment scale)

    The changes in ADAS-cog will constitute the secondary research outcome. The lower the score, the lighter the symptoms.

    Measured: baseline, 4 weeks and 4 weeks after treatment

  6. DMS(Delayed matching-to-sample task)

    The DMS paradigm is a commonly used paradigm for studying working memory. This study, combined with EEG monitoring, can investigate the changes in the encoding, maintenance, and retrieval phases of working memory.The changes in DMS will constitute the secondary research outcome.

    Measured: baseline, 4 weeks and 4 weeks after treatment

  7. MEP(Motor evoked potential)

    MEP is a muscle motor complex potential recorded by stimulating the motor cortex in the contralateral target muscle; Check the overall synchronization and integrity of the transmission and transmission pathways of motor nerves from the cortex to the muscles.The changes in MEP will constitute the secondary research outcome.

    Measured: baseline, 4 weeks and 4 weeks after treatment

  8. MRI measures

    This study mainly applied resting blood oxygen level dependent functional magnetic resonance imaging (BOLD), arterial spin labeling (ASL), and magnetic resonance diffusion tensor imaging (DTI) techniques to evaluate the changes in functional connectivity of the cerebellar dentate nucleus in healthy subjects and patients before and after 4 weeks of TMS treatment, as well as the changes in the cerebellar cortical white matter fiber bundles one month after treatment.

    Measured: baseline, 4 weeks and 4 weeks after treatment

  9. EEG(electroencephalogram)

    Use electroencephalography to record resting state electroencephalograms before and after treatment, as well as during follow-up, as well as TMS synchronized electroencephalograms stimulated by single pulse TMS in the bilateral cerebellar dentate nucleus, and task state electroencephalograms during DMS paradigm. Analyzing changes in power spectrum, neural oscillations, and functional connectivity of EEG data before and after treatment and during follow-up

    Measured: baseline, 4 weeks and 4 weeks after treatment
