The genomic psychiatry cohort: Partners in discovery

The Genomic Psychiatry Cohort (GPC) is a longitudinal resource designed to provide the necessary population‐based sample for large‐scale genomic studies, studies focusing on Research Domain Criteria (RDoC) and/or other alternate phenotype constructs, clinical and interventional studies, nested case–control studies, long‐term disease course studies, and genomic variant‐to‐phenotype studies. We provide and will continue to encourage access to the GPC as an international resource. DNA and other biological samples and diagnostic data are available through the National Institute of Mental Health (NIMH) Repository. After appropriate review and approval by an advisory board, investigators are able to collaborate in, propose, and co‐lead studies involving cohort participants. © 2013 Wiley Periodicals, Inc.     

Radiation damage to the brain: Neuropsychiatric aspects

Although radiation necrosis of the brain is a recognized complication of irradiation of the central nervous system, the psychiatric aspects of this phenomenon are less well defined. Two cases of radiation necrosis in which psychiatric symptoms were a prominent part of the clinical picture are presented. Factors that determine the evolution and clinical presentation of radiation necrosis are reviewed. In particular, the role of the consultation psychiatrist in the diagnosis and management of such patients is discussed.     

利培酮合并知母皂甙元治疗阴性症状为主的精神分裂症的双盲随机对照研究(英文)

目的探讨知母皂甙元是否能增强利培酮的治疗作用,以及两者联用是否能显著提高阴性症状为主的精神分裂症病人的认知功能。方法本研究采用双盲、安慰剂对照的平行设计方案。研究对象随机分为知利培酮合并母皂甙组(n=41)和利培酮合并安慰剂组(n=39),在治疗前及治疗第2、4、8周,分别对患者进行阳性与阴性症状量表(Positive and Negative Symptoms Scale,PANSS)、韦氏记忆量表(Wechsler Memory Scale,WMS)、韦氏简式智力量表(modified Chinese Wechsler Adult Intelligence Scale,mWAIS)、简明精神量表(Brief Psychiatry Rating Scale,BPRS)和临床疗效总评量表(Clinical Global Impression,CGI)评定。每位患者共随访8周,整个研究持续2年。结果在治疗结束时,两组在PANSS、WMS及mWAIS的减分上无统计学差异,两组间不良事件发生率亦无明显差异。结论知母皂甙不会增强利培酮对阴性症状为主的精神分裂症的治疗作用。给予知母皂甙(200mg/d)合并利培酮(2–...     

奥氮平治疗精神分裂症的对照研究

目的探讨奥氮平治疗精神分裂症的疗效及不良反应。方法将213例精神分裂症患者随机分为研究组（奥氮平治疗）和对照组（氯丙嗪治疗），共治疗8周，治疗前后应用简明精神病评定量表（BPRS）、住院患者观察量表（NOSIE）和副反应量表（TESS）分别评定疗效及不良反应。结果在治疗后的第2周末、第8周末，研究组的BPRS各因子分及总分均低于对照组，差异具有显著性意义（P〈0．05）。在治疗后的第2周末、第8周末，研究组的NOSIE的社会功能、个人整洁、总积极因素因子分及病情总估计分均高于对照组，抑郁、迟缓及总消极因素因子分均低于对照组，差异均具有显著性意义（P〈0．05）。奥氮平组的不良反应少于氯丙嗪组。结论奥氮平可有效改善精神分裂症患者的精神病症状和社会功能。
