Study summary

This study intends to apply structural and functional brain network neuroimaging techniques combined with image post-processing methods to explore the differences in brain network changes in PD patients with cognitive impairment after DBS or TMS.

Read the detailed description

A variety of post-processing methods (VBM, SPM, CAT, LEAD-DBS, etc.) were used to analyze structural brain network images (sMRI, DTI) and functional brain network images (rs-fMRI, PET) based on connectomics, and combined with the changes of clinical symptoms before and after treatment. To study the mechanism of the influence of neural regulation on brain network, and further analyze how DBS and TMS improve the cognitive symptoms of PD patients from the perspective of brain connectomics, so as to explore the occurrence and development of Parkinson's disease with cognitive impairment and the possible improvement mechanism.According to the individual differences in clinical symptoms of different PD patients, better stimulation sites and the best brain network are sought to further guide the surgical plan, so as to obtain the best clinical treatment effect.

Groups and cohorts

  • Cognitive Impairment (CI) group and No Cognitive Impairment (NCI) group

    We intend to recruit 200 patients with primary PD to undergo DBS surgery or only TMS treatment according to whether the surgical indication is available. We will observe the changes in cognitive function of patients before and after different brain stimulation treatments. Parkinson's disease patients with cognitive impairment after brain stimulation were divided into cognitive impairment group, and those without cognitive impairment after treatment were divided into no cognitive impairment group

    Device: Deep Brain Stimulation(DBS) and Transcranial Magnetic Stimulation(TMS)

Interventions

  • DeviceDeep Brain Stimulation(DBS) and Transcranial Magnetic Stimulation(TMS)

    We observed the changes in cognitive function of patients before and after different brain stimulation treatments, and further compared the effects of different brain stimulation treatments on cognitive function of PD patients and the related mechanisms according to whether DBS surgery was performed or TMS therapy was given only according to the surgical indications.

What researchers measure

Primary outcomes

  1. Montreal Cognitive Rating Scale(MoCA)

    The Montreal Cognitive Rating Scale was used to assess the overall cognitive status of patients before and after treatment

    Time frame: December 2023 to December 2026

  2. verbal fluency test (VF)

    VF test was used to assess frontal executive function and related language function

    Time frame: December 2023 to December 2026

Secondary outcomes

  1. the third part of the Unified Parkinson's Disease Rating Scale (UPDRS III)

    Measures motor symptoms and Higher scores indicate more severe impairment in motor function

    Time frame: December 2023 to December 2026
