目的探讨丘脑底核脑深部电刺激对帕金森病病人抑郁障碍的疗效及其机制。方法回顾性分析21例帕金森病合并抑郁障碍病人的临床资料,均行丘脑底核脑深部电刺激术,术前及术后3、6个月分别应用汉密尔顿抑郁量表(HAMD)评分和统一帕金森病评定量表(UPDRS)运动评分对抑郁障碍和运动功能进行临床评价并分析其相关性。结果术后UPDRS运动评分和HAMD评分均显著下降(均P0.05),但是抑郁症状的改善与运动功能的改善并没有明显的相关性(P0.05)。结论丘脑底核脑深部电刺激能够明显改善帕金森病病人的抑郁症状,其机制可能与丘脑底核受到刺激影响脑内神经递质的变化有关,术后运动功能的改善不是抑郁症状改善的主要原因。 相似文献

OBJECTIVES: Glutamate mediated excitotoxicity of the hyperactive subthalamic nucleus (STN) has been reported to contribute to nigral degeneration in Parkinson's disease (PD). Deep brain stimulation of the STN (STN DBS), in its role as a highly effective treatment of severe PD motor complications, has been thought to inhibit STN hyperactivity and therefore decrease progression of PD. METHODS: In a prospective two centre study, disease progression was determined by means of serial (18)F-fluorodopa (F-dopa) positron emission tomography (PET) in 30 patients with successful STN DBS over the first 16 (SD 6) months after surgery. RESULTS: Depending on the method of PET data analysis used in the two centres, annual progression rates relative to baseline were 9.5-12.4% in the caudate and 10.7-12.9% in the putamen. CONCLUSIONS: This functional imaging study is the first to demonstrate a continuous decline of dopaminergic function in patients with advanced PD under clinically effective bilateral STN stimulation. The rates of progression in patients with STN DBS were within the range of previously reported data from longitudinal imaging studies in PD. Therefore this study could not confirm the neuroprotective properties of DBS in the STN target. 相似文献

BACKGROUND: Deep brain stimulation (DBS) of the globus pallidus interna (GPi) and subthalamic nucleus (STN) has been reported to relieve motor symptoms and levodopa-induced dyskinesia in patients with advanced Parkinson disease (PD). Although it has been suggested that stimulation of the STN may be superior to stimulation of the GPi, comparative trials are limited. OBJECTIVE: To extend our randomized, blinded pilot comparison of the safety and efficacy of STN and GPi stimulation in patients with advanced PD. DESIGN: This study represents the combined results from our previously published, randomized, blinded, parallel-group pilot study and additional patients enrolled in our single-center extension study. SETTING: Oregon Health and Science University in Portland.Patients Twenty-three patients with idiopathic PD, levodopa-induced dyskinesia, and response fluctuations were randomized to implantation of bilateral GPi or STN stimulators. Patients and evaluating clinicians were blinded to stimulation site. All patients were tested preoperatively while taking and not taking medications and after 3, 6, and 12 months of DBS. MAIN OUTCOME MEASURES: Postoperatively, response of symptoms to DBS, medication, and combined medication and DBS was evaluated. Twenty patients (10 in the GPi group and 10 in the STN group) completed 12-month follow-up. RESULTS: Off-medication Unified Parkinson's Disease Rating Scale motor scores were improved after 12 months of both GPi and STN stimulation (39% vs 48%). Bradykinesia tended to improve more with STN than GPi stimulation. No improvement in on-medication function was observed in either group. Levodopa dose was reduced by 38% in STN stimulation patients compared with 3% in GPi stimulation patients (P = .08). Dyskinesia was reduced by stimulation at both GPi and STN (89% vs 62%). Cognitive and behavioral complications were observed only in combination with STN stimulation. CONCLUSION: Stimulation of either the GPi or STN improves many features of advanced PD. It is premature to exclude GPi as an appropriate target for DBS in patients with advanced disease. 相似文献

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has proved to be effective for tremor in Parkinson’s disease
(PD). Most of the recent studies used only clinical data to analyse tremor reduction. The objective of our study was to quantify
tremor reduction by STN DBS and antiparkinsonian medication in elderly PD patients using an objective measuring system. Amplitude
and frequency of resting tremor and re-emergent resting tremor during postural tasks were analysed using an ultrasound-based
measuring system and surface electromyography. In a prospective study design nine patients with advanced PD were examined
preoperatively off and on medication, and twice postoperatively during four treatment conditions: off treatment, on STN DBS,
on medication, and on STN DBS plus medication. While both STN DBS and medication reduced tremor amplitude, STN DBS alone and
the combination of medication and STN DBS were significantly superior to pre- and postoperative medication. STN DBS but not
medication increased tremor frequency, and off treatment tremor frequency was significantly reduced postoperatively compared
to baseline. These findings demonstrate that STN DBS is highly effective in elderly patients with advanced PD and moderate
preoperative tremor reduction by medication. Thus, with regard to the advanced impact on the other parkinsonian symptoms,
STN DBS can replace thalamic stimulation in this cohort of patients. Nevertheless, medication was still effective postoperatively
and may act synergistically. The significantly superior efficacy of STN DBS on tremor amplitude and its impact on tremor frequency
in contrast to medication might be explained by the influence of STN DBS on additional neural circuits independent from dopaminergic
neurotransmission.

To examine the effects of levodopa (L ‐dopa) and deep brain stimulation of the subthalamic nucleus (STN‐DBS) on sensory symptoms and signs in Parkinson's disease (PD). Seventeen patients with PD were included. (1) Presence of sensory symptoms and (2) effects of L ‐dopa and STN‐DBS on sensory symptoms and signs [assessed by quantitative sensory testing (QST)] were examined 6 months after starting STN‐DBS. In addition, in 12 of these patients, presence of sensory symptoms prior and post STN‐DBS was compared. Pain was most frequently nociceptive. In about 30–40%, pain and sensory symptoms were associated with PD motor symptoms. In most of these cases, pain responded to L ‐dopa. Intensity of pain was reduced post STN‐DBS compared to pre STN‐DBS. L ‐Dopa had no influence on detection thresholds, whereas STN‐DBS improved thermal detection thresholds. However, thermal and mechanical pain thresholds were uninfluenced by L ‐dopa or STN‐DBS. Although some patients reported an improvement of pain with STN‐DBS or L ‐dopa, objectively pain sensitivity as assessed by QST was not altered by STN‐DBS or L ‐dopa suggesting that there is no evidence for a direct modulation of central pain processing by L ‐dopa or STN‐DBS. © 2010 Movement Disorder Society 相似文献

DBS of the STN improves quality of life (QoL) and motor function not only in advanced Parkinson's disease (PD), but also in PD with early motor complications, as shown in the recent EARLYSTIM study. In spite of the evidence in favor of STN‐DBS, the findings of the EARLYSTIM study have recently been controversially debated. Here, we argue that a placebo or lessebo effect is unlikely to have relevantly contributed to the favorable outcome of STN‐DBS in the EARLYSTIM study. The method of quantification of the placebo effect of DBS in a previous publication reveals flaws leading to implausible results, and therefore the placebo effect of DBS remains currently elusive, especially because blinding of PD patients with STN‐DBS as a crucial preassumption for assessing a placebo effect is practically impossible. Moreover, we claim that the extent of such a placebo effect is most likely very small. Specific challenges of STN‐DBS at an earlier stage of PD and inclusion criteria are the risk of inclusion of patients who later evolve to atypical parkinsonism, the risk of a floor effect for the benefit from DBS, the need for experienced multidisciplinary care including prevention of suicidal behavior, and the need for highly qualified long‐term follow‐up. The EARLYSTIM study has shown that STN‐DBS may be proposed earlier on in the course of PD, as soon as motor complications start to cause relevant disability despite proper medical management. This can lead to a gain of several years of improved QoL. © 2014 International Parkinson and Movement Disorder Society 相似文献
