NCT06090682

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Montreal Cognitive Rating Scale(MoCA)

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

    December 2023 to December 2026

  • verbal fluency test (VF)

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

    December 2023 to December 2026

Secondary Outcomes (1)

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

    December 2023 to December 2026

Study Arms (1)

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

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.

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