帕金森病患者自主神经功能障碍评估

目的：评估帕金森病（PD）患者中自主神经功能障碍症状发生比例、各症状分布的差异，及其与PD临床特点之间的关系。方法：应用SCOPA-AUT量表、统一帕金森病评分量表（UPDRS）、日常生活能力量表（ADL）、Hamilton抑郁量表和简易智能量表（MMSE）对116例原发性PD患者进行评估。结果：SCOPA-AUT总分和消化系统（GI）症状、排尿（UR）症状、体温调节（TH）症状、性功能（SX）症状评分均高于对照组，差异有极显著统计学意义（P=0．0001）。SCOPA-AUT总分与UPDRS评分、Hamilton抑郁量表评分呈正相关（P〈0．001），与生活质量ADL评分呈负相关（P〈0．001）。结论：自主神经功能障碍在PD早期就会出现，并随着疾病进展而加重，影响患者的生活质量。

帕金森病患者的交感神经皮肤反应研究

帕金森病(Parkinson`s disease,PD)是多见于中老年人的慢性神经系统变性疾病,自主神经功能障碍是帕金森病患者较常见的临床症状之一,可表现为脂颜多汗、便泌及直立性低血压等[1,2]。交感神经皮肤反应(Sympathetic skin re-sponse,SSR)是一种与汗腺活动有关、并反映交感神经节后纤维的表皮电位,临床上用于检测相关疾病所致的植物神经功能失常,是一种较为客观的电生理指标[3]。我们对50例帕金森病患者进行SSR检测,并以正常健康组作对照,现报道如下。1资料与方法1.1一般资料50例帕金森病患者均为2000年3月~2004年8月在我院神经内科住院的患…     

帕金森病的自主神经功能障碍

帕金森病(PD)患者出现自主神经功能障碍的较普遍,如皮脂溢、便秘、性功能障碍、流涎、尿失禁、吞咽困难、多汗、直立性低血压等,有时可能是主要的临床表现,在年龄较大、病程较长的患者中更多见。这与PD病变所累及的范围较广泛有关。PD除累及黑质、蓝斑外,其他部位如下丘脑背部、迷走神经背核、交感神经节、肾上腺髓质也受影响。蓝斑、下丘脑背部、迷走神经背核为多巴胺能神经元,这些部位的损害可造成自主神经功能障碍,尤其与直立性低血压有关。许多研究还表明抗PD药物也可造成自主神经功能障碍。现就PD的自主神经功能障碍及其相关研究进…     

帕金森病交感神经皮肤反应的临床研究

Objective To assess the value of detecting sympathetic skin response (SSR) in the diagnosis of autonomic dysfunction in patients with Parkinson disease (PD). Methods SSR measurement was performed in 47 PD patients and 20 healthy control subjects and the results were compared. The SSR was also comparatively analyzed between patients with and those without autonomic dysfimction. Results Compared with the healthy controls, the PD patients showed significantly lowered mean amplitude (2.56±1.47 vs 1.87±0.26, P<0.05) and prolonged latency (1.42±0.29 vs 1.55± 0.18, P<0.05) of the SSR in the upper limbs, with also lowered mean amplitude (0.76±0.39 vs 0.49±0.21, P<0.05) and prolonged latency (2.04±0.27 vs 2.13±0.16, P<0.05) in the lower limbs. Compared with the PD patients without autonomic dysfunction, those having autonomic dysfunction showed significantly lowered mean amplitude (1.89±0.33 vs 1.75±0.21, P<0.05) and prolonged latency (1.53±0.15 vs 1.56±0.17, P<0.05) of SSR in the upper limbs and lowered mean amplitude (0.51±0.17 vs 0.46±0.20,P<0.05) and prolonged latency (2.08±0.24 vs 2.17±0.18, P<0.05) in the lower limbs. Conclusion The results of SSR measurements are consistent with the clinical manifestations of the PD patients. SSR can be of value in the diagnosis of autonomic nerve dysfunction in PD.

Sympathetic vasoconstrictor reflexes in Parkinson's disease with autonomic dysfunction

Centrally and locally elicited sympathetic vasoconstrictor responses were examined in 12 patients with symptoms and signs of cardiovascular autonomic dysfunction due to Parkinson's disease. The sympathetic reflex mechanisms were measured in skeletal muscle and subcutaneous tissue of the arm and leg using the 133-Xenon washout technique. This method allows differentiation between local and central sympathetic reflexes in different tissues. The results indicate an abolished centrally mediated vasoconstrictor response in skeletal muscle in the arm and a decreased response in skeletal muscle in the leg and in subcutaneous tissue. This is in agreement with an autonomic dysfunction located in the central nervous system. A possible spinal sympathetic reflex controlling blood flow in subcutaneous tissue and leg muscles is considered. The sympathetic vasoconstrictor responses in parkinsonian patients without autonomic failure were of normal magnitude and the responses were not affected by long-term levodopa treatment.     

Evaluation of sympathetic skin response in Parkinson's disease

There is no clear definition on the role of sympathetic skin response (SSR) in the evaluation of patients with Parkinson's disease (PD). We recorded the SSR of the palms of 64 controls and 46 patients with PD to electrical stimulation of the median nerve at the wrist. We analyzed onset latency and peak-to-peak amplitude. A study of parasympathetic function (R–R interval analysis) was also undertaken. We found that patients with PD had more absent SSRs than controls. The mean amplitude of the SSR was significantly reduced in both lower and upper limbs of PD patients in comparison with control subjects (p<0.001). The onset latency was longer in the lower limbs of these patients in respect to the control group (p<0.003). There was a significant inverse correlation between SSR amplitudes and age, severity and late onset of the disease. There was no association of these parameters with dysautonomic symptoms or R–R interval variation. In conclusion, there is a significant association between altered SSR and PD and an inverse correlation in this group of patients between SSR values and older age, greater severity and later onset of disease. Therefore, the study of SSR may provide valuable information on cholinergic sympathetic function in patients with PD.
