抑郁症
·编者按·
抑郁症是一种常见的情感性精神障碍.据统计,全球约有3.4亿人受其影响,我国的抑郁症患者也已经超过2600万.有研究表明,大约16%的人在其一生中的某个阶段可能经历抑郁发作.此外,抑郁症患者自杀、自伤的危险性非常高.据报道,自杀死亡者中40%患有抑郁症.根据WHO最新报告,预计到2020年,抑郁症将成为导致人类死亡和致残的第二大类疾病.“蓝色隐忧”,让人担忧.
抑郁症又称抑郁障碍,以心境低落为主要的临床特征,可以从不同程度上表现为闷闷不乐、兴趣减退,甚至痛不欲生、悲观绝望.部分病例有明显的焦虑和精神运动型迟滞和激越,意志活动减退,严重者有自杀企图或行为.除情绪症状外,患者还有可能出现睡眠障碍、食欲减退或增强、性欲减退或消失等躯体症状.同时伴发出现记忆力下降、注意力障碍等认知功能缺损.
目前,抑郁症的病因尚未有明确定论,但是可以确定,抑郁症的发生有着明确的生物学特性.此外,心理和社会环境等因素也起到不可忽视的作用.在现代医学模式下,很多研究者从生物、心理和社会三个方面探讨抑郁症的发病机理,并形成了生物-心理-社会的统一模式,其中涉及神经、内分泌以及免疫等方面.具体来说,遗传因素、神经生化改变、神经内分泌假说、抑郁症的细胞因子学说以及心理社会因素都被纳入到抑郁症的发病机制探讨当中.其中,从神经生化学角度探讨抑郁症发病机理的相关研究中,主要将五羟色胺(5-HT)、去甲肾上腺素(norepinephrine,NE)、多巴胺(Dopamine,DA)、乙酰胆碱(acetylcholine,Ach)中的一种或几种归纳为抑郁症发病的相关因素.
目前,药物治疗是最主要的抑郁症治疗方法,在这一部分研究中,很多研究者应用了动物模型,取得了一定的效果.20世纪50~60年代,出现了包括单胺氧化酶抑制剂的第一代抗抑郁药;20世纪80年代,第二代抗抑郁药5- HT再摄取抑制剂诞生.目前,具有抗抑郁作用的中草药也被用于治疗抑郁症.除药物外,社会心理治疗也是常用的方法,常用的社会心理治疗包括:支持性心理治疗、动力学心理治疗、认知治疗、行为治疗、人际心理治疗、婚姻和家庭治疗.此外,对于一些较为严重的状况,还会应用脑部刺激等治疗方法.有研究者指出,联合治疗模式正在成为抑郁症治疗新趋势,主要包括药物治疗与心理治疗的联合模式和药物治疗与物理治疗的联合模式.

抑郁症是一种高患病率、高疾病负担、高复发率、高致残率、高自杀率的慢性精神疾病.根据WHO最新报告,预计到2020年,抑郁症将成为导致人类死亡和致残的第二大类疾病.自20世纪80年代以来,抑郁症治疗的研究取得了长足的进步,特别是第 3代抗抑郁药 5-羟色胺再摄取抑制剂的诞生,开启了抑郁症治疗的新篇章,大大增强了药物治疗的安全性、方便性.随后 10年相继研发出第4代5-羟色胺与去甲肾腺素双通道再摄取抑制剂(SNRI类,如万拉法新)、5-羟色胺与去甲肾腺素双通道调节剂(NaSSa类,如米氮平),为医师给患者制订个性化治疗方案提供了更安全、更有效、更多的药物选择.随着基因组学、脑影像学、神经科学研究的深入,2010年《自然》杂志主编PhilipCampbel提出抑郁症是脑部发育性疾病,至此,抑郁症属于功能性疾病的观念被彻底更正,因此,药物治疗仍然是当前抑郁症治疗的主要手段.尽管第3、4代抗抑郁药有更高的治疗缓解率、更好的耐受性而成为一线抗抑郁药物,而且对中、重度抑郁症也具有良好的疗效,但目前一线抗抑郁药物的治愈率仅为30%,导致患者及家属对治疗效果不满意.症状的复燃和复发是抑郁症的病程特征,抑郁症状复燃和复发的原因涉及生理、心理及社会等多种原因,因此,心理治疗作为治疗抑郁症的一个重要手段越来越受到关注.尽管循证研究证实认知行为治疗(cognitive behavioral therapy,CBT)对抑郁症治疗有效,但心理治疗起效是一个渐进、累积产生效应的过程,比药物起效更慢,因此,患者早期往往难以耐受逐渐起效的过程,甚至难以相信心理治疗的效果,而更愿意接受药物治疗.抑郁症的物理治疗包括电休克治疗(electroconvulsive therapy,ECT)、迷走神经刺激(vagusnerve stimulation,VNS)及经颅磁刺激(transcranial magnetic stimulation,TMS)等,其中改良型无抽搐电休克治疗(modified electroconvulsive therapy,MECT)抑郁症的有效率达70%~90%.研究显示不同的物理治疗其疗效也因人而异.无论是药物治疗、心理治疗,还是物理物治疗均提示有效,但临床实际效果不尽如人意,而且同样的药物、同样的治疗方法,不同人却疗效不同,是什么原因导致疗效的差异?还有哪些因素影响着疗效与结局?如何提升抑郁症治疗的疗效?这对患者和医师都具有非常重要的意义.越来越多的研究证据表明抑郁症是一种病因、机制及疗效异质性很大的疾病,很多学者发现患者依从性、治疗偏好等因素均对治疗结局产生微妙而重要的影响,现就对近年来抑郁症治疗领域研究中出现的新理念、新趋势、新进展展开述评.
1抑郁症治疗管理新理念
1.1基于评估治疗(measurement-based care,MBC)模式被推荐
虽然循证医学及美国精神病协会抑郁障碍防治指南对抑郁症治疗过程评估作出了规范的推荐,但临床实践与规范推荐之间仍有较大差异.过去基于经验性治疗方式、治疗方法及治疗过程不规范,医院之间及医师之间诊治水平相差大,抗抑郁药物治疗用量不充分、疗程不完整,常规评估未广泛实施,导致患者或医师对临床症状、社会生活功能了解不充分、不全面,患者往往根据自己主观症状改善而自行停药,或医师根据患者症状改善的描述而过早减少药物剂量或停药,导致较难达到抑郁症的治疗目标.在此背景下,MBC治疗模式或量化治疗模式应运而生.国外学者提出 MBC治疗是精神科或心理科临床获得更高疗效的有效策略.MBC是一种在临床实践中实施循证医学路径的治疗模式,由以下几部分组成:①准确评估症状及严重程度,确保足够的抗抑郁药物剂量;②评估药物的耐受性、监测药物不良反应,确保治疗的安全性;③评估还包括患者社会、心理及生活功能损害和恢复状态,以确定治愈的程度.MBC治疗模式在慢性病如糖尿病、高血压管理中早已被广泛使用,医师根据临床量化指标及时调整药物剂量或治疗方案,以提高医疗质量,改善患者转归.精神科最早在抑郁症的序贯治疗研究(sequenced treatment alternatives to relieve depression*,STAR*D)中推广使用MBC,采用简单、可信的工具对患者的症状、不良反应、安全性等方面进行系统评估.MBC在精神科的治疗实用性和有效性已在多个临床研究及临床实践中被验证.2010年版美国精神病学会(American psychiatric association,APA)抑郁症治疗指南推荐将MBC加入抑郁症疾病的管理,2012年第5版《精神疾病诊断与统计手册》(DSM-Ⅴ)指出:精神疾病的评估是DSM-Ⅴ的工作目标和重大更新之一.
目前,国外研究证明患者健康问卷-9项量表(patient health questionnaire-9,PHQ-9)是一种简单、有效的评估工具.PHQ-9量表由9个条目组成,包括抑郁症核心症状、生活、社会、心理功能,可以协助医师判断是否抑郁,以及抑郁严重程度,医师可根据其评分结果决定后续治疗方案,通过评估避免患者和医师停留在疾病主观感觉的认识上,而让患者和医师对疾病状态的变化有客观、量化、系统、全面的认识,提高患者的依从性,从而提高临床疗效.MBC在国内精神科领域仍是一个较新的概念.2013年第十届中国神经精神科年会上王刚教授在报告中谈到,采用随机、对照方式验证了MBC治疗模式的有效性,其研究证实量化治疗组在整体有效性和服药依从性方面均显著优于常规治疗组,量化治疗作为一种更加系统、规范、高效标准化的治疗模式,已成为精神科治疗的新模式.
1.2提高依从性作为治疗的重要策略被提出
药物治疗是控制症状和预防复发的主要手段.有研究表明,首次抑郁发作的患者其复发率至少为50%,已有2次抑郁发作的患者其复发率则高达80%~90%.研究显示,在临床抗抑郁药治疗研究中,未依从医师治疗方案的患者达40%~70%,而且随着治疗时间越长,患者依从性比例呈递减趋势,抑郁症脱落率高达50%~70%.不依从行为包括患者自行减少药物剂量或提前中断治疗等.抑郁症是一种慢性疾病,决定了其需要长期治疗的必要性.APA抑郁症治疗指南中推荐治疗分4期:急性治疗期、巩固治疗期、维持治疗期、撤药治疗期,完成4个治疗周期一般需要1~2年,甚至更长,对患者、家属来说是一个很大的挑战.有学者提出患者依从性比有效的治疗方案更重要.因此,患者依从性成为影响临床疗效的关键因素之一.影响患者依从性因素包括患者因素、药物因素及疾病因素.其中患者因素包括对疾病的态度、患者治疗偏好等,成为影响患者依从性的中介调节因素.药物因素包括药物吞服困难、日服药的次数、服药方法的复杂性、同时服药的种类、药物引起不良反应的严重程度、药物的物理性状等.疾病的因素包括对疾病的认知、对共患病的认识、对药物疗效的了解、对治疗起效时间的了解、对潜在不良反应的了解、对症状改善的简单认识等.研究显示良好的依从性有助于提高临床治愈率.因此,2010年APA在抑郁症治疗推荐指南中增设了患者和家属教育这一项,将提高依从性作为治疗的重要策略提出.教育内容包括疾病基本知识、治疗方法及疗效、药物服用方法、药物副作用应对、疗程、对治愈的识别与理解等,其目的是尽可能让患者参与到治疗决策中来,从而提高患者的依从性.
1.3患者治疗偏好作为治疗策略被建议
随着健康理念不断更新,治疗中患者个人更倾向于某种治疗方式或者某种治疗药物,这一患者治疗偏向的概念在临床实践中得以广泛应用.在临床实践中,医师往往选择对患者最重要、最有价值、最大获益的治疗,但某些研究,包括STAR*D研究得到的数据显示,患者对治疗的不同偏好会导致治疗反应差异很大.2012年Steidtmann等对患者选择匹配和不匹配治疗结局效应值的荟萃分析发现,主动接受医师制订治疗方案的患者比未接受或被动接受医师制订治疗方案的患者退出治疗的可能性减少1/3~1/2,接受医师制订治疗方案的患者不仅退出更少,而且临床改善更快、结局更好.这提示患者治疗偏好可通过影响依从性和合作性而最终影响治疗结局.研究显示,抑郁起效与治疗偏好有关,仅选择药物治疗的患者预后不佳,患者治疗偏好是其疗效不佳和脱落的预测因子.研究表明,40%~60%的抑郁症患者选择药物联合心理治疗,而 20%~40%的抑郁症患者没有治疗的偏好,其中偏向药物治疗往往更易脱落,偏向心理治疗的患者依从性更高.患者偏好受年龄、疾病种类、花费、服药方便性等多种因素影响.在治疗上有偏向性的患者特征:年龄偏大,更加认同抑郁症是一种疾病,既往服用抗抑郁药的比例更高,既往发作次数更多,既往就诊率更高,且在治疗3个月即呈现出更快的症状改善.这些研究结果给临床医师提供了一个有益的启发,重视和利用患者治疗偏好是提高临床疗效的策略之一.
1.4早期起效作为提高疗效的重要策略被强调
抑郁症治疗早期疗效一般在2~4周起效.抑郁症治疗起效慢一直困扰着患者、家属和医师,不但延长和加重患者及家属痛苦,增加经济负担,而且易导致患者对治疗失去信心,中断治疗,从而降低依从性.研究发现,有些抗抑郁药物可以在2周内起效,且快速起效与最终治疗结局密切相关.一项包括1982—2003年42项临床试验、纳入了6562例抑郁症患者、评估抗抑郁药物能否预测患者预后的荟萃分析研究显示,研究结束时在获得稳定临床治愈者中92%(1084/1172)为早期改善者,早期的疗效可以有效预测临床预后,早期疗效预测稳定疗效及临床治愈率的敏感度分别在81%和87%以上.一项前瞻性、多中心的包括705例抑郁症住院患者的研究采用汉密顿抑郁自杀因子(Hamilton depression rating scale for depression,HAMD-3)评分,评估患者早期疗效与自杀意念的关系,发现早期无效患者自杀意念的发生率比早期有效患者升高3~5倍,而且早期有效患者显著降低了悲观情绪.这些研究给临床医师启示:在抗抑郁治疗的同时,选择起效快、临床治愈率高的药物可以更快改善患者的症状,减轻患者的痛苦,降低自杀的风险,从而增加患者依从性;早期起效是抑郁症早期治疗的重要策略之一.
2联合治疗模式成为抑郁症治疗新趋势
2.1药物治疗与心理治疗联合模式
抗抑郁药物仅对1/3的患者完全有效,循证研究已表明CBT治疗不仅对治疗抑郁症有效,而且可通过改变患者抑郁认知模式、纠正其不合理信念从而降低复发率,但心理治疗起效更慢,导致很多患者并不接受治疗.什么样的方法既能快速起效,又能降低复发率,提升疗效的稳定性呢?过去50年的精神病学实践见证了精神药物的迅速发展,同时心理治疗也得到了越来越多的重视.大量证据显示药物治疗和心理治疗联合方式可以更好地改善抑郁症状及其预后.2013年Wiles等的研究表明:在综合医院难治性抑郁症药物中辅以CBT治疗,在治疗6个月时,联合CBT治疗组患者有效性比常规药物治疗组增加了3倍,提示药物治疗与心理治疗联合使患者的获益更多.研究显示,在初始药物治疗失败的情况下,最佳治疗选择是药物治疗与心理治疗联合.心理治疗方法很多,在临床实践中,医师会根据患者的具体情况而选择不同的心理治疗方法,如精神分析、家庭治疗、人际关系治疗以及团体治疗等.除了CBT治疗被循证医学证实是有效的方法外,其他心理治疗方法,如精神分析、系统家庭治疗、人际关系治疗等均在抑郁症患者中应用,但其治疗效果受患者个体因素及医师因素影响很大,而且心理治疗更强调个案化,因此,至今尚少见大样本或循证研究证实精神分析、家庭治疗对抑郁症治疗有效,但并不能否定或低估精神分析、家庭治疗以及人际关系治疗抑郁症有效的事实.事实上,临床较多患者在接受家庭治疗后,家庭沟通模式得到改善,家庭成员增加了对患者抑郁症的认识,从而改变了自己行为,家庭人际关系随之变得友善、包容、互助;一些患者在接受人际关系治疗后,学习了基本人际交往技巧,使自己变得自信起来,改变了自卑和压抑,从而抑郁情绪得到了改善.临床常见现象是家庭成员对患者越能理解和关心,患者症状改善更快而且维持疗效越好,否则即使暂时好转,也难以维持疗效的稳定.因此,药物治疗联合心理治疗成为抑郁症治疗领域的新趋势.早期通过药物治疗改善患者睡眠,躯体症状以及缓解抑郁、焦虑情绪,后期实施心理治疗,纠正患者不合理观念,提高患者对自我的认识与理解,从而更全面改变患者抑郁状态,提升患者生活质量.然而,开展心理治疗需要医师接受系统理论和操作技能的培训,还需考虑医师的经验、伦理、法律,以及患者对心理治疗的感受与信念等诸多问题.心理治疗被倡导和重视,终将推动抑郁症临床治疗模式的改变和完善.此外,由于CBT治疗需要医患双方面对面,并且需要很长时间、多次,甚至长达几十次的面谈,患者心理阻抗比较大,为CBT治疗带来很大阻力和不便,能长期坚持治疗对患者来说具有很大挑战.一种新的心理治疗方式——电话CBT治疗引起了学者的兴趣与关注.Mohr等发现,在18个月治疗过程中,电话访谈和面谈均能降低HMAD和PQH-9评分,但6个月时面谈患者HMAD和PQH-9评分均优于电话访谈患者.在18个月治疗过程中,与面谈患者相比,接受电话访谈患者终止治疗的比例更少,电话访谈和面谈脱落率差异有统计学意义(20.9% vs 32.7%,P=0.02),前5个月中,面谈较电话访谈脱落率更高(4.3% vs 13.3%).该研究显示,非传统心理干预方式在抑郁症治疗中显示出其积极的价值.
2.2药物治疗联合物理治疗
大脑中电脉冲是信息加工与传递的基础,因此,大脑电刺激或脉冲的改变在理论上能够改变大脑局部神经生化学的变化,从而改变大脑局部的功能.精神医学正处于快速发展的阶段,对精神疾病的机制及治疗手段研究近几年不断推陈出新.在精神科具有代表性的物理治疗手段包括ECT、VNS及TMS等.ECT是整个新物理治疗家族中的鼻祖,是APA指南推荐的严重抑郁症的治疗选择.ECT联合药物治疗是治疗新发抑郁症的有效手段,但有研究表明ECT与急性和部分慢性记忆缺失相关,故未能被充分利用.而MECT总体疗效与传统ECT疗效相当,且对记忆的影响较少,易被患者及家属接受,目前在临床得以推广.在2011年164届美国精神病年会上有学者报告MECT可以早期用于抑郁症患者,能快速改善抑郁症患者的临床症状.TMS是20世纪80年代中期发展起来的一种影响和改变大脑功能的生物刺激技术,已有研究证实其治疗抑郁症的安全性及有效性,对初始药物治疗失败的患者,TMS治疗被APA推荐为抑郁障碍的治疗方法之一.VNS是不适用于绝大多数其他治疗方法的长期(慢性)抑郁症患者的最佳治疗选择,被FDA批准用于治疗难治性抑郁.在临床实践中,有医师针对患者个体化特征,采取药物治疗、心理治疗、物理治疗3种治疗方法联合,同样收到一定效果.
3展望
目前研究显示,抗抑郁药有效率仅为60%~80%,治愈率也仅为30%,起效时间2~4周.近年,药物研究最新的热点是氯胺酮的快速起效.研究表明氯胺酮治疗抑郁症4~72 h治疗有效率及治愈率平均为77%和43%,但维持疗效时间较短.因此,抗抑郁药仍然存在起效较慢、治愈率不高的问题,不能满足患者对治疗及时起效的需要以及对治疗结局的期待.如何提升其疗效的持久性与稳定性已成为该领域研究热点.此外,临床医师如认识到患者依从性、治疗偏好、早期起效等因素都潜在影响着治疗的效果,不仅拓展了其临床思维和视野,而且为其提供了新的治疗策略和循证治疗依据.医师将这些影响因素纳入对疾病的管理和处置考虑中,将显示出比既往更好的治疗效果,这些重要发现对完善、规范抑郁症的临床治疗有很大的指导意义.无论从病因学、疾病机制、流行病学、临床现象学,还是治疗学等方面考虑,抑郁症都是一种复杂、异质性很大的精神疾病.对抑郁症的遗传学、神经回路标记或心理学标记潜在价值目前也不清楚,这些问题有望在将来得到澄清.即使这些问题得到澄清,不同的患者需要哪种治疗方法,同样需要医师借助大量的临床研究资料和丰富临床经验,对患者进行全面判断,做出治疗决策时必须权衡科学证据,并了解药理学和心理学知识,确保选择最好的治疗措施.因此,对抑郁症的治疗不仅需要从生物层面,从心理、社会的层面进行,还需要有一个完整的康复体系,全面提升抑郁症患者生理、心理、社会功能.今后抑郁症治疗模式是精神科医师、心理治疗师、社会工作者三方联合,以便真正提高抑郁症的治愈率,使抑郁症的整体发病率及致残率降低.

An inventory for measuring depression
Beck AT; Erbaugh J; Ward CH; et al.
Abstract: The difficulties inherent in obtaining consistent and adequate diagnoses for the purposes of research and therapy have been pointed out by a number of authors. Pasamanickin a recent article viewed the low interclinician agreement on diagnosis as an indictment of the present state of psychiatry and called for "the development of objective,measurable and verifiable criteria of classification based not on personal or parochial considerations,but on behavioral and other objectively measurable manifestations."

Collaborative Management to Achieve Treatment Guidelines — Impact On Depression in Primary-Care
Katon W; Vonkorff M; Lin E; et al.
Abstract: Objective: To compare the effectiveness of a multifaceted intervention in patients with depression in primary care with the effectiveness of ''usual care'' by the primary care physician.
Design: A randomized controlled trial among primary care patients with major depression or minor depression.
Patients: Over a 12-month period a total of 217 primary care patients who were recognized as depressed by their primary care physicians and were willing to take antidepressant medication were randomized,with 91 patients meeting criteria for major depression and 126 for minor depression.
Interventions: lntervention patients received increased intensity and frequency of visits over the first 4 to 6 weeks of treatment(visits 1 and 3 with a primary care physician,visits 2 and 4 with a psychiatrist)and continued surveillance of adherence to medication regimens during the continuation and maintenance phases of treatment. Patient education in these visits was supplemented by videotaped and written materials.
Main Outcome Measures: Primary outcome measures included short-term(30 day)and long-term(90 day)use of antidepressant medication at guideline dosage levels,satisfaction with overall care for depression and antidepressant medication,and reduction in depressive symptoms.
Results: In patients with major depression,the intervention group had greater adherence than the usual care controls to adequate dosage of antidepressant medication for 90 days or more(75.5% vs 50.0%; P<0.01),were more likely to rate the quality of the care they received for depression as good to excellent(93.0% vs 75.0%; P<0.03),and were more likely to rate antidepressant medications as helping somewhat to helping a great deal(88.1% vs 63.3%; P<0.01). Seventy-four percent of intervention patients with major depression showed 50% or more improvement on the Symptom Checklist-90 Depressive Symptom Scale compared with 43.8% of controls(P<0.01),and the intervention patients also demonstrated a significantly greater decrease in depression severity over time compared with controls(P<0.004). In patientswith minor depression,the intervention group had significantly greater adherence than controls to adequate dosage of antidepressant medication for 90 days or more(79.7% vs 40.3%; P<0.001)and more often rated antidepressant medication as helping somewhat to helping a great deal(81.8% vs 61.4%; P<0.02). However,no significant differences were found between the intervention and control groups in the percentage of patients who were satisfied with the care they received for depression(94.4% vs 89.3%),in the percentage who experienced a 50% or more decrease in depressive symptoms,or in the decrease of depressive symptoms over time.
Conclusion: A multifaceted intervention consisting of collaborative management by the primary care physician and a consulting psychiatrist,intensive patient education,and surveillance of continued refills of antidepressant medication improved adherence to antidepressant regimens in patients with major and with minor depression. It improved satisfaction with care and resulted in more favorable depressive outcomes in patients with major,but not minor,depression.

Depression Following Myocardial-Infarction — Impact On 6-Month Survival
Frasuresmith N; Lesperance F; Talajic,M
Abstract: Objective: To determine if the diagnosis of major depression in patients hospitalized following myocardial infarction(MI)would have an independent impact on cardiac mortality over the first 6 months after discharge.
Design: Prospective evaluation of the impact of depression assessed using a modified version of the National Institute of Mental Health Diagnostic Interview Schedule for major depressive episode. Cox proportional hazards regression was used to evaluate the independent impact of depression after control for significant clinical predictors in the data set.
Setting: A large,university-affiliated hospital specializing in cardiac care,located in Montreal,Quebec.
Patients: All consenting patients(N=222)who met established criteria for MI between August 1991 and July 1992 and who survived to be discharged from the hospital. Patients were interviewed between 5 and 15 days following the MI and were followed up for 6 months. There were no age limits(range,24 to 88 years; mean,60 years). The sample was 78% male.
Primary Outcome Measure: Survival status at 6 months.
Results: By 6 months,12 patients had died. All deaths were due to cardiac causes. Depression was a significant predictor of mortality(hazard ratio,5.74; 95% confidence interval,4.61 to 6.87; P=0.0006). The impact of depression remained after control for left ventricular dysfunction(Killip class)and previous MI,the multivariate significant predictors of mortality in the data set(adjusted hazard ratio,4.29;95% confidence interval,3.14 to 5.44; P=0.013).
Conclusion: Major depression in patients hospitalized following an MI is an independent risk factor for mortality at 6 months. Its impact is at least equivalent to that of left ventricular dysfunction(Killip class)and history of previous MI. Additional study is needed to determine whether treatment of depression can influence post-MI survival and to assess possible underlying mechanisms.

Reduction of Prefrontal Cortex Glucose-Metabolism Common to 3 Types Of Depression
Baxter LR; Schwartz JM; Phelps ME; et al.
Abstract: Using positron emission tomography,we studied cerebral glucose metabolism in drug-free,age- and sex-matched,right-handed patients with unipolar depression(n=10),bipolar depression(n=10),obsessive-compulsive disorder(OCD)with secondary depression(n=10),OCD without major depression(n=14),and normal controls(n=12). Depressed patients were matched for depression on the Hamilton Depression Rating Scale,and subjects with OCD without depression and OCD with depression had similar levels of OCD without depression and OCD with depression had similar levels of OCD pathology. We also studied six non-sex-matched patients with mania. Mean(±SD)glucose metabolic rates for the left dorsal anterolateral prefrontal cortex,divided by the rate for the ipsilateral hemisphere as a whole(ALPFC/hem),were similar in the primary depressions(unipolar depression =1.05±0.05; bipolar depression =1.04±0.05),and were significantly lower than those in normal controls(1.12±0.06)or OCD without depression(1.15±0.05). Results for the right hemisphere were similar. Values in subjects with OCD with depression(1.10±0.05)were also significantly lower than in subjects with OCD without depression,and values in subjects with bipolar depression were lower than those in manic subjects(1.12±0.03)on this measure in the left hemisphere,although results were not significant in the right hemisphere. There was a significant correlation between the HAM-D score and the left ALPFC/hem. With medication for depression(n=12),the left ALPFC/hem increased significantly and the percentage change in the Hamilton scale score correlated with the percentage change in the left ALPFC/hem.

产后抑郁症
陈燕杰,钟友彬
摘要:产后抑郁症发病率国外报道为3.5%~33%,国内报道为3.8%~16.7%.临床表现涉及情绪、认识、行为、生活等几个方面,特点为产后2周发病,4~6周症状明显.主要特征是以婴儿、丈夫相关事为主,一般认为病因是多因素的.但是,产妇分娩前后体内的内分泌变化及产妇的个性心理特点,是产后抑郁症发生的重要先决条件,一些应激性生活事件和产前产时的并发症又是产后抑郁症的主要促发因素.目前,诊断尚缺乏客观指标,多依据各种症状自评量表,由产妇自填后以相应的评分结果判定.主要是心理治疗,约1/3的患者需药物治疗.

抑郁症与中医“郁证”的关系探讨
曲淼,唐启盛
摘要:结合古代文献及临床研究,从文献记载和临床症状、病因病机等方面论述抑郁症与郁证的差异及共性.认为中医“郁证”本身含有两层含义,一为以病机而立病名,二为情志之病,中医有关抑郁症的描述只见于后者,而且有关抑郁症的描述也在多种中医病名的症状群中出现,因此抑郁症与郁证二者不是简单的等同关系.并提出抑郁症中医辨证应以虚证为纲,结合临床观察,以益肾补虚为大法治疗抑郁症,取得了较好的疗效.

The hospital anxiety and depression scale
Zigmond,AS ; Snaith,RP
Abstract: A self-assessment scale has been developed and found to be a reliable instrument for detecting states of depression and anxiety in the setting of an hospital medical outpatient clinic. The anxiety and depressive subscales are also valid measures of severity of the emotional disorder. It is suggested that the introduction of the scales into general hospital practice would facilitate the large task of detection and management of emotional disorder in patients under investigation and treatment in medical and surgical departments.

New depression scale designed to be sensitive to change
Montgomery SA; Asberg M
Abstract: The construction of a depression rating scale designed to be particularly sensitive to treatment effects is described. Ratings of 54 English and 52 Swedish patients on a 65 item comprehensive psychopathology scale were used to identify the 17 most commonly occurring symptoms in primary depressive illness in the combined sample. Ratings on these 17 items for 64 patients participating in studies of four different antidepressant drugs were used to create a depression scale consisting of the 10 items which showed the largest changes with treatment and the highest correlation to overall change. The inner-rater reliability of the new depression scale was high. Scores on the scale correlated significantly with scores on a standard rating scale for depression,the Hamilton Rating Scale(HRS),indicating its validity as a general severity estimate. Its capacity to differentiate between responders and non-responders to antidepressant treatment was better than the HRS,indicating greater sensitivity to change. The practical and ethical implications in terms of smaller sample sizes in clinical trials are discussed.

Development and validation of a geriatric depression screening scale: a preliminary report
Yesavage JA; Brink,TL; Rose TL; et al.
Abstract: A new Geriatric Depression Scale(GDS)designed specifically for rating depression in the elderly was tested for reliability and validity and compared with the Hamilton Rating Scale for Depression(HRS-D)and the Zung Self-Rating Depression Scale(SDS). In constructing the GDS a 100-item questionnaire was administered to normal and severely depressed subjects. The 30 questions most highly correlated with the total scores were then selected and readministered to new groups of elderly subjects. These subjects were classified as normal,mildly depressed or severely depressed on the basis of Research Diagnostic Criteria(RDC)for depression. The GDS,HRS-D and SDS were all found to be internally consistent measures,and each of the scales was correlated with the subject's number of RDC symptoms. However,the GDS and the HRS-D were significantly better correlated with RDC symptoms than was the SDS. The authors suggest that the GDS represents a reliable and valid self-rating depression screening scale for elderly populations.

A self-rating depression scale
Zung WWK
Abstract: The fact that there is a need for assessing depression,whether as an affect,a symptom,or a disorder is obvious by the numerousscales and inventories available and in use today.The need to assess depression simply and specifically as a psychiatric disorder has not been met by most scales available today. We became acutely aware of this situation in a research project where we needed to correlate both the presence and severity of a depressive disorder in patients with other parameters such as arousal response during sleep and changes with treatment of the depressive disorder. It was felt that the general depression scales used were insufficient for our purpose and that the more specific scales were also inadequate. These inadequacies related to factors such as the length of a scale or inventory being too long and too time consuming,especially for a patient.

Influence of life stress on depression: Moderation by a polymorphism in the 5-HTT gene
Caspi A; Sugden K; Moffitt TE; et al.
Abstract: In a prospective-longitudinal study of a representative birth cohort,we tested why stressful experiences lead to depression in some people but not in others. A functional polymorphism in the promoter region of the serotonin transporter(5-HTT)gene was found to moderate the influence of stressful life events on depression. Individuals with one or two copies of the short allele of the 5-HTT promoter polymorphism exhibited more depressive symptoms,diagnosable depression,and suicidality in relation to stressful life events than individuals homozygous for the long allele. This epidemiological study thus provides evidence of a gene-by-environment interaction,in which an individual's response to environmental insults is moderated by his or her genetic makeup.

The PHQ-9 - Validity of a brief depression severity measure
Kroenke K; Spitzer RL; Williams JBW
Abstract: Objective: While considerable attention has focused on improving the detection of depression,assessment of severity Is also important in guiding treatment decisions. Therefore,we examined the validity of a brief,new measure of depression severity. Measurements: The Patient Health Questionnaire(PHQ)is a self-administered version of the PRIME-MD diagnostic instrument for common mental disorders. The PHQ-9 is the depression module,which scores each of the 9 DSM-IV criteria as "0"(not at all)to "3"(nearly every day). The PHQ-9 was completed by 6,000 patients in 8 primary care clinics and 7 obstetrics-gynecology clinics. Construct validity was assessed using the 20-item Short-Form General Health Survey,self-reported sick days and clinic visits. and symptom-related difficulty. Criterion validity was assessed against an Independent structured mental health professional(MHP)interview in a sample of 580 patients. Results: As PHQ-9 depression severity Increased,there was a substantial decrease in functional status on all 6 SF-20 subscales. Also,symptom-related difficulty,sick days,and health care utilization increased. Using the MHP reinterview as the criterion standard,a PHQ-9 score greater than or equal to 10 had a sensitivity of 88% and a specificity of 88% for major depression. PHQ-9 scores of 5. 10,15. and 20 represented mild,moderate,moderately severe,and severe depression,respectively. Results were similar in the primary care and obstetrics-gynecology samples. Conclusion: In addition to making criteria-based diagnoses of depressive disorders,the PHQ-9 Is also a reliable and valid measure of depression severity. These characteristics plus Its brevity make the PHQ-9 a useful clinical and research tool.

The epidemiology of major depressive disorder - Results from the National Comorbidity Survey Replication(NCS-R)
Kessler RC; Berglund P; Demler O; et al.
Abstract: Context Uncertainties exist about prevalence and correlates of major depressive disorder(MDD).
Objective: To present nationally representative data on prevalence and correlates of MDD by Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-IV)criteria,and on study patterns and correlates of treatment and treatment adequacy from the recently completed National Comorbidity Survey Replication(NCS-R).
Design: Face-to-face household survey,conducted from February 2001 to December 2002.
Setting: The 48 contiguous United States.
Participants: Household residents ages 18 years or older(N=9090)who responded to the NCS-R survey.
Main: Outcome Measures Prevalence and correlates of MDD using the World Health Organization's(WHO)Composite International Diagnostic Interview(CIDI),12-month severity with the Quick Inventory of Depressive Symptomatology Self-Report(QIDS-SR),theSheehan Disability Scale(SDS),and the WHO disability assessment scale(WHO-DAS). Clinical reinterviews used the Structured Clinical Interview for DSM-IV.
Results: The prevalence of CIDI MDD for lifetime was 16.2%(95% confidence interval [CI],15.1-17.3)(32.6-35.1 million US adults)and for 12-month was 6.6%(95% CI; 5.9-7.3)(13.1-14.2 million US adults). Virtually all CIDI 12-month cases were independently classified as clinically significant using the QIDS-SR,with 10.4% mild,38.6% moderate,38.0% severe,and 12.9% very severe. Mean episode duration was 16 weeks(95% Cl,15.1-17.3). Role impairment as measured by SIDS was substantial as indicated by 59.3% of 12-month cases with severe or very severe role impairment. Most lifetime(72.1%)and 12-month(78.5%)cases had comorbid CIDI/DSM-IV disorders,with MDD only rarely primary. Although 51.6%(95% Cl,46.1-57.2)of 12-month cases received health care treatment for MDD,treatment was adequate in only 41.9%(95% Cl,35.9-47.9)of these cases,resulting in 21.7%(95% Cl,18.1-25.2)of 12-month MDD being adequately treated. Sociodemographic correlates of treatment were far less numerous than those of prevalence.
Conclusions: Major depressive disorder is a common disorder,widely distributed in the population,and usually associated with substantial symptom severity and role impairment. While the recent increase in treatment is encouraging,inadequate treatment is a serious concern. Emphasis on screening and expansion of treatment needs to be accompanied by a parallel emphasis on treatment quality improvement.

Detection of postnatal depression. Development of the 10-item Edinburgh Postnatal Depression Scale
Cox JL; Holden JM; Sagovsky,R
Abstract: The development of a 10-item self-report scale(EPDS)to screen for Postnatal Depression in the community is described. After extensive pilot interviews a validation study was carried out on 84 mothers using the Research Diagnostic Criteria for depressive illness obtained from Goldberg's Standardised Psychiatric Interview. The EPDS was found to have satisfactory sensitivity and specificity,and was also sensitive to change in the severity of depression over time. The scale can be completed in about 5 minutes and has a simple method of scoring. The use of the EPDS in the secondary prevention of Postnatal Depression is discussed.

失眠与抑郁关系2008—2013年研究进展及存在问题
张继辉,刘亚平,潘集阳
摘要:失眠障碍和抑郁症是成人和儿童最常见的精神障碍之一.以前的观点认为,失眠症状是抑郁症的一个常见伴随症状,会随着抑郁症的缓解而消失.但逐渐积累的证据显示,失眠症状不仅是抑郁症起病及复发的危险因素,也是抑郁症治疗后的残留症状.最新的《精神障碍诊断与统计手册第5版》和《睡眠障碍国际分类第3版》将失眠障碍看作是与其他精神障碍共病的状态,这将对未来失眠症的诊疗和临床研究产生重要的影响.本文主要就2008-2013年关于失眠(障碍或症状)和抑郁症的研究进展,讨论失眠与抑郁症在疾病层面及症状层面上的关系.

Anxiety,Depression,and Cigarette Smoking: A Transdiagnostic Vulnerability Framework to Understanding Emotion-Smoking Comorbidity
Leventhal AM; Zvolensky MJ
Abstract: Research into the comorbidity between emotional psychopathology and cigarette smoking has often focused upon anxiety and depression's manifest symptoms and syndromes,with limited theoretical and clinical advancement. This article presents a novel framework to understanding emotion-smoking comorbidity. We propose that transdiagnostic emotional vulnerabilities-core biobehavioral traits reflecting maladaptive responses to emotional states that underpin multiple types of emotional psychopathology-link various anxiety and depressive psychopathologies to smoking. This framework is applied in a review and synthesis of the empirical literature on 3 transdiagnostic emotional vulnerabilities implicated in smoking:(a)anhedonia(Anh; diminished pleasure/interest in response to rewards),(b)anxiety sensitivity(AS; fear of anxiety-related sensations),and(c)distress tolerance(DT; ability to withstand distressing states). We conclude that Anh,AS,and DT collectively(a)underpin multiple emotional psychopathologies,(b)amplify smoking's anticipated and actual affect-enhancing properties and other mechanisms underlying smoking,(c)promote progression across the smoking trajectory(i.e.,initiation,escalation/progression,maintenance,cessation/relapse),and(d)are promising targets for smoking intervention. After existing gaps are identified,an integrative model of transdiagnostic processes linking emotional psychopathology to smoking is proposed. The model's key premise is that Anh amplifies smoking's anticipated and actual pleasure-enhancing effects,AS amplifies smoking's anxiolytic effects,and poor DT amplifies smoking's distress terminating effects. Collectively,these processes augment the reinforcing properties of smoking for individuals with emotional psychopathology to heighten risk of smoking initiation,progression,maintenance,cessation avoidance,and relapse. We conclude by drawing clinical and scientific implications from this framework that may generalize to other comorbidities.

Treatment-Resistant Bipolar Depression: A Randomized Controlled Trial of Electroconvulsive Therapy Versus Algorithm-Based Pharmacological Treatment
Schoeyen HK; Kessler U; Andreassen OA; et al.
Abstract: Objective: Electroconvulsive therapy(ECT)is regarded by many clinicians as the most effective treatment for treatment-resistant bipolar depression,but no randomized controlled trials have been conducted,to the authors' knowledge. They compared efficacy measures of ECT and algorithm-based pharmacological treatment in treatment-resistant bipolar depression.
Method: This multicenter,randomized controlled trial was carried out at seven acute-care psychiatric inpatient clinics throughout Norway and included 73 bipolar disorder patients with treatment-resistant depression. The patients were randomly assigned to receive either ECT or algorithm-based pharmacological treatment. ECT included three sessions per week for up to 6 weeks,right unilateral placement of stimulus electrodes,and brief pulse stimulation.
Results: Linear mixed-effects modeling analysis revealed that ECT was significantly more effective than algorithm-based pharmacological treatment. The mean scores at the end of the 6-week treatment period were lower for the ECT group than for the pharmacological treatment group: by 6.6 points on the Montgomery-Asberg Depression Rating Scale(SE=2.05,95% CI=2.5-10.6),by 9.4 points on the 30-item version of the Inventory of Depressive Symptomatology-Clinician-Rated(SE=2.49,95% CI=4.6-14.3),and by 0.7 points on the Clinical Global Impression for Bipolar Disorder(SE=0.31,95% CI=0.13-1.36). The response rate was significantly higher in the ECT group than in the group that received algorithm-based pharmacological treatment(73.9% versus 35.0%),but the remission rate did not differ between the groups(34.8% versus 30.0%).
Conclusion: Remission rates remained modest regardless of treatment choice for this challenging clinical condition.

Efficacy and safety of deep transcranial magnetic stimulation for major depression:a prospective multicenter randomized controlled trial
Levkovitz Y; Isserles M; Padberg F; et al.
Abstract: Major depressive disorder(MDD)is a prevalent and disabling condition,and many patients do not respond to available treatments. Deep transcranial magnetic stimulation(dTMS)is a new technology allowing non-surgical stimulation of relatively deep brain areas. This is the first double-blind randomized controlled multicenter study evaluating the efficacy and safety of dTMS in MDD. We recruited 212 MDD outpatients,aged 22-68 years,who had either failed one to four antidepressant trials or not tolerated at least two antidepressant treatments during the current episode. They were randomly assigned to monotherapy with active or sham dTMS. Twenty sessions of dTMS(18 Hz over the prefrontal cortex)were applied during 4 weeks acutely,and then biweekly for 12 weeks. Primary andsecondary efficacy endpoints were the change in the Hamilton Depression Rating Scale(HDRS-21)score and response/remission rates at week 5,respectively. dTMS induced a 6.39 point improvement in HDRS-21 scores,while a 3.28 point improvement was observed in the sham group(p=0.008),resulting in a 0.76 effect size. Response and remission rates were higher in the dTMS than in the sham group(response: 38.4 vs. 21.4%,p=0.013; remission: 32.6 vs. 14.6%,p=0.005). These differences between active and sham treatment were stable during the 12-week maintenance phase. dTMS was associated with few and minor side effects apart from one seizure in a patient where a protocol violation occurred. These results suggest that dTMS constitutes a novel intervention in MDD,which is efficacious and safe in patients not responding to antidepressant medications,and whose effect remains stable over 3 months of maintenance treatment.

Metabotropic glutamate receptor 3 activation is required for long-term depression in medial prefrontal cortex and fear extinction
Walker AG; Wenthur CJ; Xiang ZX; et al.
Abstract: Clinical studies have revealed that genetic variations in metabotropic glutamate receptor 3(mGlu3)affect performance on cognitive tasks dependent upon the prefrontal cortex(PFC)and may be linked to psychiatric conditions such as schizophrenia,bipolar disorder,and addiction. We have performed a series of studies aimed at understanding how mGlu3 influences PFC function and cognitive behaviors. In the present study,we found that activation of mGlu3 can induce long-term depression in the mouse medial PFC(mPFC)in vitro. Furthermore,in vivo administration of a selective mGlu3 negative allosteric modulator impaired learning in the mPFC-dependent fear extinction task. The results of these studies implicate mGlu3 as a major regulator of PFC function and cognition. Additionally,potentiators of mGlu3 may be useful in alleviating prefrontal impairments associated with several CNS disorders.

Enhancing Depression Mechanisms in Midbrain Dopamine Neurons Achieves Homeostatic Resilience
Friedman AK; Walsh JJ; Juarez B; et al.
Abstract: Typical therapies try to reverse pathogenic mechanisms. Here,we describe treatment effects achieved by enhancing depression-causing mechanisms in ventral tegmental area(VTA)dopamine(DA)neurons. In a social defeat stress model of depression,depressed(susceptible)mice display hyperactivity of VTA DA neurons,caused by an up-regulated hyperpolarization-activated current(I-h). Mice resilient to social defeat stress,however,exhibit stable normal firing of these neurons. Unexpectedly,resilient mice had an even larger Ih,which was observed in parallel with increased potassium(K+)channel currents. Experimentally further enhancing Ih or optogenetically increasing the hyperactivity of VTA DA neurons in susceptible mice completely reversed depression-related behaviors,an antidepressant effect achieved through resilience-like,projection-specific homeostatic plasticity. These results indicate a potential therapeutic path of promoting natural resilience for depression treatment.

The association between low vitamin D and depressive disorders
Milaneschi Y; Hoogendijk W; Lips P; et al.
Abstract: It has been hypothesized that hypovitaminosis D is associated with depression but epidemiological evidence is limited. We investigated the association between depressive disorders and related clinical characteristics with blood concentrations of 25-hydroxyvitamin D [25(OH)D] in a large cohort. The sample consisted of participants(aged 18-65 years)from the Netherlands Study of Depression and Anxiety(NESDA)with a current(N=1102)or remitted(N=790)depressive disorder(major depressive disorder,dysthymia)defined according to DSM-IV criteria,and healthy controls(N=494). Serum levels of 25(OH)D measured and analyzed in multivariate analyses adjusting for sociodemographics,sunlight,urbanization,lifestyle and health. Of the sample,33.6% had deficient or insufficient serum 25(OH)D(<50 nmol l-1). As compared with controls,lower 25(OH)D levels were found in participants with current depression(P=0.001,Cohen's d=0.21),particularly in those with the most severe symptoms(P=0.001,Cohen's d=0.44). In currently depressed persons,25(OH)D was inversely associated with symptom severity(beta=-0.19,s.e. -0.07,P=0.003)suggesting a dose-response gradient,and with risk(relative risk =0.90,95% confidence interval =0.82-0.99,P=0.03)of having a depressive disorders at 2-year follow-up. This large cohort study indicates that low levels of 25(OH)D were associated to the presence and severity of depressive disorder suggesting that hypovitaminosis D may represent an underlying biological vulnerability for depression. Future studies should elucidate whether-the highly prevalent-hypovitaminosis D could be cost-effectively treated as part of preventive or treatment interventions for depression.

From Stress to Inflammation and Major Depressive Disorder:A Social Signal Transduction Theory of Depression
Slavich GM; Irwin MR
Abstract: Major life stressors,especially those involving interpersonal stress and social rejection,are among the strongest proximal risk factors for depression. In this review,we propose a biologically plausible,multilevel theory that describes neural,physiologic,molecular,and genomic mechanisms that link experiences of social-environmental stress with internal biological processes that drive depression pathogenesis. Central to this social signal transduction theory of depression is the hypothesis that experiences of social threat and adversity up-regulate components of the immune system involved in inflammation. The key mediators of this response,called proinflammatory cytokines,can in turn elicit profound changes in behavior,which include the initiation of depressive symptoms such as sad mood,anhedonia,fatigue,psychomotor retardation,and social-behavioral withdrawal. This highly conserved biological response to adversity is critical for survival during times of actual physical threat or injury. However,this response can also be activated by modern-day social,symbolic,or imagined threats,leading to an increasingly proinflammatory phenotype that may be a key phenomenon driving depression pathogenesis and recurrence,as well as the overlap of depression with several somatic conditions including asthma,rheumatoid arthritis,chronic pain,metabolic syndrome,cardiovascular disease,obesity,and neurodegeneration. Insights from this theory may thus shed light on several important questions including how depression develops,why it frequently recurs,why it is strongly predicted by early life stress,and why it often co-occurs with symptoms of anxiety and with certain physical disease conditions. This work may also suggest new opportunities for preventing and treating depression by targeting inflammation.

Rapid regulation of depression-related behaviours by control of midbrain dopamine neurons
Chaudhury D; Walsh JJ; Friedman AK; et al.
Abstract: Ventral tegmental area(VTA)dopamine neurons in the brain's reward circuit have a crucial role in mediating stress responses(1-4),including determining susceptibility versus resilience to social-stress-induced behavioural abnormalities(5). VTA dopamine neurons show two in vivo patterns of firing: low frequency tonic firing and high frequency phasic firing(6-8). Phasic firing of the neurons,which is well known to encode reward signals(6,7,9),is upregulated by repeated social-defeat stress,a highly validated mouse model of depression(5,8,10-13). Surprisingly,this pathophysiological effect is seen in susceptible mice only,with no apparent change in firing rate in resilient individuals(5,8). However,direct evidence-in real time-linking dopamine neuron phasic firing in promoting the susceptible(depression-like)phenotype is lacking. Here we took advantage of the temporal precision and cell-type and projection-pathway specificity of optogenetics to show that enhanced phasic firing of these neurons mediates susceptibility to social-defeat stress in freely behaving mice. We show that optogenetic induction of phasic,but not tonic,firing in VTA dopamine neurons of mice undergoing a subthreshold social-defeat paradigm rapidly induced a susceptible phenotype as measured by social avoidance and decreased sucrose preference. Optogenetic phasic stimulation of these neurons also quickly induced a susceptible phenotype in previously resilient mice that had been subjected to repeated social-defeat stress. Furthermore,we show differences in projection-pathway specificity in promoting stress susceptibility: phasic activation of VTA neurons projecting to the nucleus accumbens(NAc),but not to the medial prefrontal cortex(mPFC),induced susceptibility to social-defeat stress. Conversely,optogenetic inhibition of the VTA-NAc projection induced resilience,whereas inhibition of the VTA-mPFC projection promoted susceptibility. Overall,these studies reveal novel firing-pattern-and neural-circuitspecific mechanisms of depression.

Dopamine neurons modulate neural encoding and expression of depression-related behaviour
Tye KM; Mirzabeko,JJ; Warde,MR; et al.
Abstract: Major depression is characterized by diverse debilitating symptoms that include hopelessness and anhedonia(1). Dopamine neurons involved in reward and motivation(2-9)are among many neural populations that have been hypothesized to be relevant(10),and certain antidepressant treatments,including medications and brain stimulation therapies,can influence the complex dopamine system. Until now it has not been possible to test this hypothesis directly,even in animal models,as existing therapeutic interventions are unable to specifically target dopamine neurons. Here we investigated directly the causal contributions of defined dopamine neurons to multidimensional depression-like phenotypes induced by chronic mild stress,by integrating behavioural,pharmacological,optogenetic andelectrophysiological methods in freely moving rodents. We found that bidirectional control(inhibition or excitation)of specified midbrain dopamine neurons immediately and bidirectionally modulates(induces or relieves)multiple independent depression symptoms caused by chronic stress. By probing the circuit implementation of these effects,we observed that optogenetic recruitment of these dopamine neurons potently alters the neural encoding of depression-related behaviours in the downstream nucleus accumbens of freely moving rodents,suggesting that processes affecting depression symptoms may involve alterations in the neural encoding of action in limbic circuitry.

The neuroprogressive nature of major depressive disorder: pathways to disease evolution and resistance,and therapeutic implications
Moylan S; Maes M; Wray NR; et al.
Abstract: In some patients with major depressive disorder(MDD),individual illness characteristics appear consistent with those of a neuroprogressive illness. Features of neuroprogression include poorer symptomatic,treatment and functional outcomes in patients with earlier disease onset and increased number and length of depressive episodes. In such patients,longer and more frequent depressive episodes appear to increase vulnerability for further episodes,precipitating an accelerating and progressive illness course leading to functional decline. Evidence from clinical,biochemical and neuroimaging studies appear to support this model and are informing novel therapeutic approaches. This paper reviews current knowledge of the neuroprogressive processes that may occur in MDD,including structural brain consequences and potential molecular mechanisms including the role of neurotransmitter systems,inflammatory,oxidative and nitrosative stress pathways,neurotrophins and regulation of neurogenesis,cortisol and the hypothalamic-pituitary-adrenal axis modulation,mitochondrial dysfunction and epigenetic and dietary influences. Evidence-based novel treatments informed by this knowledge are discussed.

Burden of Depressive Disorders by Country,Sex,Age,and Year: Findings from the Global Burden of Disease Study 2010
Ferrari AJ; Charlson FJ; Norman RE; et al.
Abstract: Background: Depressive disorders were a leading cause of burden in the Global Burden of Disease(GBD)1990 and 2000 studies. Here,we analyze the burden of depressive disorders in GBD 2010 and present severity proportions,burden by country,region,age,sex,and year,as well as burden of depressive disorders as a risk factor for suicide and ischemic heart disease.
Methods and Findings: Burden was calculated for major depressive disorder(MDD)and dysthymia. A systematic review of epidemiological data was conducted. The data were pooled using a Bayesian meta-regression. Disability weights from population survey data quantified the severity of health loss from depressive disorders. These weights were used to calculate years lived with disability(YLDs)and disability adjusted life years(DALYs). Separate DALYs were estimated for suicide and ischemic heart disease attributable to depressive disorders. Depressive disorders were the second leading cause of YLDs in 2010. MDD accounted for 8.2%(5.9%-10.8%)of global YLDs and dysthymia for 1.4%(0.9%-2.0%). Depressive disorders were a leading cause of DALYs even though no mortality was attributed to them as the underlying cause. MDD accounted for 2.5%(1.9%-3.2%)of global DALYs and dysthymia for 0.5%(0.3%-0.6%). There was more regional variation in burden for MDD than for dysthymia; with higher estimates in females,and adults of working age. Whilst burden increased by 37.5% between 1990 and 2010,this was due to population growth and ageing. MDD explained 16 million suicide DALYs and almost 4 million ischemic heart disease DALYs. This attributable burden would increase the overall burden of depressive disorders from 3.0%(2.2%-3.8%)to 3.8%(3.0%-4.7%)of global DALYs.
Conclusions: GBD 2010 identified depressive disorders as a leading cause of burden. MDD was also a contributor of burden allocated to suicide and ischemic heart disease. These findings emphasize the importance of including depressive disorders as a public-health priority and implementing cost-effective interventions to reduce its burden.

The appearance of yet another rating scale for measuring symptoms of mental disorder may seem unnecessary,since there are so many already in existence and many of them have been extensively used. Unfortunately,it cannot be said that per-fection has been achieved,and indeed,there is considerable room for improvement.
