简要总结
Deep brain stimulation (DBS) is recognized as the most safe and effective neurosurgical method for the treatment of advanced Parkinson's disease. However, the mechanism of relieving motor and non-motor symptoms of Parkinson's disease has not been fully clarified, and the prognosis is significantly different. This study is based on multimodal MRI technique to clarify the mechanism of DBS in relieving motor and non-motor symptoms of Parkinson's disease, and to explore imaging indicators that can predict prognosis, so as to guide the individual and accurate treatment of Parkinson's disease (PD).
详细描述
-
Preoperative and postoperative multimodal MRI scanning 1) equipment: 3TGE 750 MRI 2) sequence: resting state fMRI, DTI, 3DTI, ESWAN, ASL 3) scan status: drug shutdown period ( discontinuation of drugs for Parkinson's disease for at least 12 hours), for patients who can not adhere to MRI scanning after drug withdrawal. Record the dosage of drugs before scanning
-
Evaluation of motor and non-motor symptoms: pre-operation and 1-year post-operation 1) motor symptoms: pre-operation medication opening and closing period. Postoperative medication off/stimulation off (Med-OFF/DBS-OFF);Med-ON/DBS-OFF;Med-OFF/DBS-ON;Med-ON/DBS-ON
-
overall evaluation of motor function: MDS-UPRDS, H&Y stage
-
balance: Berg balance scale
-
dyskinesia: abnormal involuntary movement scale(AIMS)
-
end-of-dose phenomenon: WOQ19 end-of-dose phenomenon questionnaire
-
daily activity ability: SCHWAB&ENGLAND daily activity scale 2) non-motor symptoms: preoperative drug shutdown period. Postoperative drug shutdown / DBS opening
- Cognitive function: Mini Mental State Examination scale (MMSE), Montreal Cognitive Assessment scale (MoCA)
- emotion: Hamilton Depression scale (HAMD), Hamilton anxiety scale (HAMA)
- Sleep: PD Sleep scale (PDSS), Appleworth sleepiness scale (ESS), REM Sleep Behavioral Disorder questionnaire-Hong Kong (RBDQ-HK)
- pain: King Parkinson's disease pain scale (KPPS)
- fatigue: fatigue severity scale (FSS)
- autonomic nervous function assessment: autonomic nervous scale (SCOPA-AUT) h) quality of life: 39 items Parkinson's disease quality of life questionnaire (PDQ-39) 3.other records: changes in type, dose and mode of use of drugs. Daily equivalent dose of levodopa (tomlinson2010 conversion)

结局指标
主要结局
Clinical characteristics of patients
时间窗: 1 to 2 years
Age at onset; age at surgery; disease duration; level of education; comorbidities (e.g. hypertension and diabetes mellitus); parkinsonism subtype; period of motor fluctuations; time from motor fluctuations to surgery; cigarette smoking
Percentage of improvement in motor aspects (after 12 months of stimulation)
时间窗: 1 to 3 years
(UPDRS III 12 months - UPDRS III baseline)/UPDRS III baseline where UPDRS III 12 months means the score of this test in "medication off , stimulation on" condition at 12 months after implant, while UPDRS III baseline means the score of this test in "medication off " condition.The clinical outcome, or degree of symptom benefit, was defined as a ≥50% improvement on a disease severity rating scale
次要结局
