以帕金森综合征起病的人群中突触核蛋白病和tau蛋白病的发病频率及分布情况的资料知之甚少,而这对卫生保健规划制定和临床研究有重要影响。来自梅奥临床研究中心的Rodolfo Savica等医师研究了不同帕金森综合征及相关蛋白病的发病率及不同类型的分布情况,发表在2013年7月的JAMA Neurology杂志上,结果显示帕金森综合征相关的蛋白病发病率随年龄急剧增加,男性发病率高于女性。突触核蛋白病临床数量明显高于tau蛋白病。

该研究使用明尼苏达州Olmsted地区罗切斯特流行病学项目的病历连锁系统筛选所有与帕金森综合征相关的病例,时间跨度为1991年1月1日至2005年12月31日,共15男。由一位运动障碍学专家详细阅读每例患者的病例资料,使用特异的临床标准评价帕金森综合征的类型及可能蛋白病类型。评价明尼苏达州Olmsted地区人口的帕金森综合征和不同蛋白病的发病特点。

在542例帕金森综合征患者中,409 (75.5%)归于蛋白病类,其中389例(71.8%)患者推测为突触核蛋白病,264例为帕金森病(占所有病例的48.7%)。突触核蛋白的发病率为每100000人年21.0,且随着年龄增高急剧增加。tau蛋白病的总体发病率为1.1(20例患者),最主要的tau蛋白病为进行性核上性麻痹(16例患者)。36例患者为药物诱发的帕金森综合征(6.6%),11例为血管性帕金森综合征(2.0%),1例(0.2%)帕金森综合征为肌萎缩侧所硬化,1例(0.2%)为继发于手术的帕金森综合征,最后84例(15.5%)仍无法分类。在各类帕金森综合征中,男性发病率明显高于女性。最终65例脑活检中,有53例(81.5%)脑活检结果与临床诊断相符合。

该研究显示与帕金森综合征相关的蛋白病发病率随年龄急剧增加,男性发病率高于女性。突触核蛋白病临床数量明显高于tau蛋白病。活检结果证实临床对蛋白病的推测。该研究或可指导卫生保健规划的制定,同时也提供临床研究的方向。

NEJM:下丘脑刺激有助于改善早期帕金森症状

  法国和德国研究人员合作开展的一项随机试验显示,在药物治疗基础上加用下丘脑刺激,不仅可改善早期帕金森病患者的生活质量和轻度左旋多巴诱导的运动并发症,还可以减少后续的运动残疾。   主要作者W.M.M. Schüpbach博士和EARLYSTIM(对于早期帕金森病患者进行深部脑刺激的对照试验)研究组的同事指出,已知这种联合治疗对晚期帕金森病患者有益,而这一新发现提示“神经刺激可能作为较当前

ANN NEUROL:吃青椒可预防帕金森氏症

吃青椒可以预防帕金森氏症? 许多小朋友可能都跟卡通人物蜡笔小新一样不敢吃青椒,把它当成最可怕的食物, 不过国外有研究发现,吃青椒可以预防帕金森氏症,华盛顿大学研究指出,每个礼拜吃两次茄科蔬菜的人,像是青椒甜椒辣椒番茄茄子,可以预防帕金森氏症罹患的机率可降至少三成。 研究认为,是因为基底核会受到烟碱的刺激,可以增加大脑多巴胺的含量,有助降低帕金森式风险。 与帕金森相关的拓展阅读:

NEJM:脑刺激配合药物治疗早期帕金森更优

  近日,《新英格兰医学杂志》发表了一项研究表明,早期帕金森患者脑神经部刺激和药物治疗同时进行的疗效,优于仅接受药物治疗的患者。   研究人员对251名病程4年以上的早期帕金森患者进行研究,研究结果表明,对于较早期的帕金森疾病,在患者的严重运动并发症没有出现之前,脑部神经刺激优于单独药物治疗。研究人员建议临床医生不要单一依靠传统的药物来对早期帕金森患者进行治疗。与帕金森相关的拓展阅读: NEJ

2012年10月25日来自美国西北大学的研究者开发出了一种新型的化合物家族,其可以有效减缓帕金森疾病的病情发展。相关研究成果刊登于10月23日的国际杂志Nature Communications上。 帕金森疾病是第二大常见的神经变性疾病,是由于大脑多巴胺神经元死亡所引发的疾病,可以使得患者颤栗、僵硬以及行动困难,当前适应症的疗法并不能减缓病情的发展。研究者所开发的新型化合物,通过以运输钙至多巴胺
