简要总结
This study is a double blind comparative study examining the effectiveness of the transcutaneous auricular vagus nerve stimulation treatment on Parkinson's disease patients with depression. The investigators hypothesize that taVNS will improve depression and cortical activity in Parkinson's disease patients with depression.
详细描述
Participants in the Experimental group underwent fourteen consecutive daily sessions of transcutaneous auricular vagus nerve stimulation (taVNS, twice daily, 30 minutes each time) , whereas participants in the sham stimulation group underwent fourteen consecutive daily sessions of sham taVNS. Assessments of depression symptoms, motor symptoms were performed three times: at baseline, one day post intervention and 2 weeks post intervention. The cortical activity (using Functional near-infrared spectroscopy) were assessed at baseline, one day post intervention.

入选标准
- •This study recruited right-handed subjects from the Department of Neurology, Huai'an Second People's Hospital. The inclusion criteria for patients with PD and depression were as follows: diagnosis of idiopathic Parkinson's disease based on the clinical diagnostic criteria of the Movement Disorder Society; diagnosis of depressive disorder in accordance with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), with a Hamilton Depression Rating Scale (HAMD) score ≥ 8; stable medication regimens for Parkinson's disease for at least one month prior to enrollment; aged 40 to 80 years; and voluntary participation with written informed consent. In addition, age- and gender-matched non-depressed PD patients and healthy controls were enrolled to further compare brain functional characteristics among different groups.
排除标准
- •presence of cognitive impairment defined as a Montreal Cognitive Assessment (MoCA) score < 23; ongoing use of antidepressant medications; presence of contraindications related to transcutaneous auricular vagus nerve stimulation (taVNS); receipt of vagus nerve stimulation (VNS) treatment within the past month; and comorbid severe neurological, renal, cardiovascular or hepatic diseases.
结局指标
主要结局
change of Hamilton Depression Scale Score
时间窗: Assessed at baseline, one day post intervention,2 weeks post intervention
Hamilton Depression Scale (HAM-D score), which was used for assessing the degree of Depression.The differences in HAMD score before and after treatment can be used to evaluate the effect of taVNS treatment
change of Hamilton Depression Scale Score Hamilton Anxiety Scale (HAM-D score), which was used for assessing the degree of anxiety.The differences in HAMD score before and after treatment can be used to evaluate the effect of taVNS treatment
时间窗: Assessed at baseline, one day post intervention#2 weeks post intervention
