Study on Brain Network Mechanism of Deep Brain Stimulation for Parkinson's Disease

Study on Brain Network Mechanism of Deep Brain Stimulation for Parkinson's （A Retrospective Study）

As a surgical intervention, DBS can effectively relieve PD tremor, rigidity, bradykinesia and other symptoms. How to better screen patients suitable for DBS treatment and conduct reasonable preoperative and postoperative evaluation is crucial to judge the treatment effect and prognosis. The clinical symptom evaluation of PD patients can be divided into motor symptom evaluation and non-motor symptom evaluation. The motor symptoms of PD patients were evaluated by UPDRS III. The evaluation of non-motor symptoms in PD patients was mainly divided into three aspects: cognitive status, emotional status, and sleep status. Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were used to assess the cognitive status of PD patients. The Hamilton Depression Scale (HAMD) was used to assess the patients' depression status. The Hamilton Anxiety Scale (HAMA) was used to assess the patients' anxiety status. The PD Sleep Scale 2nd version, The PD Sleep Scale 2nd version, PDSS - 2), and rem Sleep Behavior Disorder Questionnaire (sweet HK) (Rapid Eye Movement Sleep behaviors Disorder Questionnaire - Hong Kong, RBDQ - HK) to assess Sleep conditions.

Inclusion Criteria:The clinical diagnosis of PD is consistent with the United Kingdom Parkinson's Disease Society Brain Bank criteria, with disease duration over 5 years, age under 75, acute levodopa motor response ≥30%, and indication for STN-DBS. -

Exclusion Criteria: patients with severe cognitive impairment, severe psychiatric disorders, acute levodopa motor response less than 30%, atypical parkinsonism, and contraindications to surgery -
