Can the effects of maternal depression upon offspring development be extrapolated to the prebirth environment, making it the earliest of adverse life events? Increasing clinical and laboratory data indicate that maternal stress and depression during critical developmental windows carry a diverse array of harmful sequelae for the offspring. The effects witnessed in animal research include neurobiological and behavioral alterations that persist into adulthood. Paralleling the preclinical literature are human studies indicating similar acute effects. The clinical implications for the psychiatric treatment of depressed women who have children will be discussed.
母亲抑郁对后代发育的影响能否外推到出生前的环境,使其成为最早的不良生活事件?越来越多的临床和实验室数据表明,在关键的发育窗口期间,母亲的压力和抑郁会给后代带来各种各样的有害后遗症。在动物研究中看到的影响包括神经生物学和行为上的改变,这些改变会持续到成年。与临床前文献平行的是人类研究,表明了类似的急性效应。对有孩子的抑郁妇女进行精神治疗的临床意义将被讨论。

Basic and clinical research documents associations between stress and a set of related psychobiologic perturbations, including dysfunction of the hypothalamic-pituitary-adrenal axis, alterations in the structure and function of the medial temporal lobe, and impairments in explicit memory. Although these associations are thought to emerge developmentally, insufficient clinical research elucidates the manner in which early trauma relates to these abnormalities. To gain a better understanding of relevant processes, we propose the use of a developmental and neurobiological approach, where data in animal models are used to inform studies in traumatized children who will be followed longitudinally. This approach will help clarify how early traumatic events have the capacity to lead to psychopathology or a healthy outcome.
基础和临床研究证明了压力与一系列相关的心理生物学扰动之间的联系,包括下丘脑-垂体-肾上腺轴的功能障碍,内侧颞叶结构和功能的改变,以及外显记忆的损害。尽管这些关联被认为是在发育过程中出现的,但没有足够的临床研究阐明早期创伤与这些异常的关系。为了更好地了解相关过程,我们建议使用发育和神经生物学方法,将动物模型中的数据用于对受创伤儿童的研究,这些儿童将被纵向跟踪。这种方法将有助于阐明早期创伤性事件是如何导致精神病理或健康结果的。

Measurement and the epidemiology of childhood trauma. 儿童创伤的测量和流行病学。
Pub Date : 2002-04-01 DOI: 10.1053/SCNP.2002.31775
George W. Brown
A review dealing with the epidemiology of traumatic experiences in childhood and adolescence will be of limited use without some attention being devoted to various demanding issues of measurement that are involved. The relevant literature on such experience is now large, with most research based on the use of standardized questionnaires. Although this has by and large been good enough to open up the field as a research enterprise, the task of establishing causal mechanisms in areas such as psychopathology is unlikely to flourish without a much greater investment in interview-based instruments using investigator-based ratings. Here research on the causative role of life events in general in the onset and course of psychiatric and physical disorder in both childhood and adulthood has a good deal to offer. Within the context of this emphasis on the importance of measurement various issues are discussed, such as the need to take account of nonabusive experience, particularly of correlated experiences such as parental neglect, the importance of obtaining time-based data and the need to take a population perspective where issues of prevalence are concerned.
如果不注意所涉及的各种苛刻的测量问题,关于儿童和青少年创伤经历的流行病学综述的作用将是有限的。关于这种经验的相关文献现在很多,大多数研究都是基于使用标准化问卷。尽管这在很大程度上已经很好地打开了研究领域的大门,但在精神病理学等领域建立因果机制的任务不太可能蓬勃发展,除非对基于访谈的工具进行更大的投资,使用基于调查者的评级。在这里,研究生活事件在儿童和成年时期精神和身体疾病的发病和过程中的致病作用,有很多东西可以提供。在强调测量的重要性的背景下,讨论了各种问题,例如需要考虑非虐待经历,特别是相关的经历,如父母忽视,获得基于时间的数据的重要性,以及需要从人口角度考虑流行问题。

Neurobiology of early life stress: nonhuman primate models. 早期生活压力的神经生物学:非人类灵长类动物模型。
Pub Date : 2002-04-01 DOI: 10.1053/SCNP.2002.31784

Numerous studies have shown that early life stress in nonhuman primates produces profound and long-lasting changes in behavior and biological function. We review several aspects of the neurobiology of early life stress, focusing on nonhuman primate experimental paradigms. There is experimental evidence that even prenatal stress can produce profound alterations in biological factors such as regulation of the hypothalamic-pituitary-adrenal (HPA) axis, biogenic amines, and immune function, as well as in behavioral measures of attention and sociability. An ongoing struggle in research studies is defining the relative contributions of nature and nurture in mediating the long-term effects of stress. Studies of social support contend that this has the capacity to buffer the deleterious effects of stressful early rearing environments, whereas social deprivations appear to have negative behavioral and medical outcomes, most notably deficits in immune function. From studies involving variable foraging demand (VFD)-reared nonhuman primates and other models, we suggest that many of the behavioral and biochemical changes produced resemble those seen in humans who suffer from depressive and anxiety conditions. Finally, there appears to be remarkable consistency of key neurobiological findings across species.
大量研究表明,非人类灵长类动物的早期生活压力会在行为和生物功能方面产生深远而持久的变化。我们回顾了早期生活压力的神经生物学的几个方面,重点是非人类灵长类动物的实验范式。有实验证据表明,即使是产前压力也会对生物因素产生深远的影响,如对下丘脑-垂体-肾上腺(HPA)轴、生物胺和免疫功能的调节,以及对注意力和社交能力的行为测量。在研究中,一个正在进行的斗争是确定先天和后天在调节压力的长期影响方面的相对贡献。社会支持的研究认为,这有能力缓冲早期养育环境压力的有害影响,而社会剥夺似乎有负面的行为和医疗结果,最明显的是免疫功能缺陷。从对可变觅食需求(VFD)饲养的非人类灵长类动物和其他模型的研究中,我们认为许多行为和生化变化与患有抑郁和焦虑的人类相似。最后,跨物种的关键神经生物学发现似乎具有显著的一致性。

Psychiatric morbidity in adult survivors of childhood trauma. 儿童创伤成年幸存者的精神疾病发病率。
Pub Date : 2002-04-01 DOI: 10.1053/SCNP.2002.31780
N. Breslau
This review focuses on child sexual abuse (CSA) as a prototype of childhood trauma and evaluates the evidence on psychiatric morbidity in adult survivors. An association between CSA and a wide range of psychiatric morbidity has been consistently documented in general population studies. The interpretation of this observed association is fraught with uncertainty that stems primarily from: (1) the retrospective nature of the data on CSA from adults' reports on their early experiences; (2) the adverse family context in which it occurs, which presents a major challenge for evaluating the effect of CSA per se; (3) the well documented lifetime comorbidity among psychiatric disorders, which leaves open questions about the specificity of CSA outcomes in adulthood. Twin study methods offer a solution to the problem of the familial context of CSA. Ascertainment of age of onset of adult disorders in future studies would increase the utility of findings for formulating psychological and biological causal models on the CSA-adult disorders connection. However, the retrospective nature of data on child abuse, because of legal and ethical restraints on research on children, is a formidable obstacle to advancing knowledge in this field.
这篇综述的重点是儿童性虐待(CSA)作为童年创伤的原型,并评估成年幸存者的精神疾病发病率的证据。在一般人群研究中,CSA与广泛的精神疾病发病率之间的关联已得到一致的证明。对这种观察到的关联的解释充满了不确定性,主要源于:(1)来自成人早期经历报告的CSA数据的回顾性;(2)不良的家庭环境,这是评估CSA本身效果的主要挑战;(3)精神疾病的终生共病,这给成年期CSA结果的特异性留下了开放性问题。双生子研究方法为CSA的家族背景问题提供了一个解决方案。在未来的研究中,确定成人疾病的发病年龄将增加研究结果的效用,以形成csa -成人疾病联系的心理和生物学因果模型。然而,由于法律和伦理对儿童研究的限制,关于虐待儿童的数据具有追溯性,这是推进这一领域知识的巨大障碍。

Neuroimaging of childhood trauma. 儿童创伤的神经影像学。
Pub Date : 2002-04-01 DOI: 10.1053/SCNP.2002.31787
Bremner Jd
Childhood abuse is a major public health problem affecting as many as a third of children in this country today at some point before their 18(th) birthday. The effects of childhood trauma on the brain are increasingly an area of interest. In trying to understand the effects of early stressors on the brain we use animal models of early stress to guide the development of hypotheses. An important potential tool in understanding the effects of abuse on the brain is neuroimaging. Neuroimaging studies in traumatized children are in a relative state of infancy. A number of methodological and ethical issues make this a difficult area for research, including problems ranging from patient motion during scanning to the ethical issues of the duty to report abuse and working with child protective services. Some studies have shown that adults abused as children have smaller volume of the hippocampus, a brain area involved in learning and memory, as measured with magnetic resonance imaging (MRI). One study in children with posttraumatic stress disorder (PTSD) did not find smaller hippocampal volume, but did find smaller brain volume and corpus callosum. Functional neuroimaging studies are consistent with alteration in function and structure of medial prefrontal cortex and hippocampus in patients with childhood sexual trauma and PTSD. These initial results suggest that childhood abuse in the setting of PTSD is associated with long-term changes in brain structure and function.
儿童虐待是一个主要的公共卫生问题,影响着今天这个国家多达三分之一的儿童在他们18岁生日之前的某个时候。童年创伤对大脑的影响日益成为人们感兴趣的领域。在试图理解早期压力源对大脑的影响时,我们使用早期压力的动物模型来指导假设的发展。了解滥用药物对大脑影响的一个重要潜在工具是神经成像。创伤儿童的神经影像学研究相对处于婴儿期。许多方法和伦理问题使这一研究领域变得困难,包括从扫描过程中患者的运动到报告虐待和与儿童保护服务合作的责任的伦理问题。一些研究表明,根据磁共振成像(MRI)的测量,小时候被虐待的成年人的海马体体积更小,海马体是大脑中与学习和记忆有关的区域。一项针对创伤后应激障碍(PTSD)儿童的研究没有发现海马体积变小,但确实发现脑体积和胼胝体变小。功能性神经影像学研究结果与儿童性创伤和创伤后应激障碍患者内侧前额叶皮质和海马的功能和结构改变一致。这些初步结果表明,创伤后应激障碍的儿童虐待与大脑结构和功能的长期变化有关。

The development and evaluation of psychotherapeutic approaches for survivors of childhood trauma has been complicated by numerous conceptual and methodological challenges. Randomized controlled clinical trials are rare, and most of these test cognitive behavioral therapy with sexually abused children. This article reviews psychosocial (nonpharmacological) treatment approaches with child and adult survivors of childhood trauma, highlighting methodologically sound studies of treatment efficacy. Implications of efficacy data for clinical practice and future research are discussed.

Neurobiology of early life stress: clinical studies. 早期生活压力的神经生物学:临床研究。
Pub Date : 2002-04-01 DOI: 10.1053/SCNP.2002.33127

A burgeoning number of clinical studies have evaluated the immediate and long-term neurobiological effects of early developmental stress, eg, child abuse and neglect or parental loss, in the past years. This review summarizes and discusses the available findings from neuroendocrine (hypothalamic-pituitary-adrenal axis, other neuroendocrine axes), neurochemical (catecholamines, serotonin, other neurotransmitters), psychophysiological (autonomic function, startle reactivity, brain electrical activity) and neuroimaging studies (brain structure, function) conducted in children or adults with a history of early life stress, with or without psychiatric disorders. Early developmental stress in humans appears to be associated with neurobiological alterations that are similar to many findings in animal models of early life stress, and likely represent the biological basis of an enhanced risk for psychopathology. Clinical studies are now beginning to explore potentially differential neurobiological effects of different types of early life stress and the existence of critical developmental periods, which may be sensitive to the neurobiological effects of specific stressors. In addition, the role of a multitude of moderating and mediating factors in the determination of individual vulnerability or resilience to the neurobiological effects of early life stress should be addressed. Findings from such studies may ultimately help to prevent the deleterious neurobiological and psychopathological consequences in the unacceptably high number of children exposed to early life stress in modern society.
在过去的几年里,越来越多的临床研究评估了早期发育压力(如儿童虐待和忽视或失去父母)对神经生物学的直接和长期影响。这篇综述总结并讨论了在有早期生活压力史,有或没有精神疾病的儿童或成人中进行的神经内分泌(下丘脑-垂体-肾上腺轴,其他神经内分泌轴),神经化学(儿茶酚胺,血清素,其他神经递质),心理生理学(自主神经功能,惊吓反应,脑电活动)和神经影像学研究(脑结构,功能)的现有发现。人类早期发育压力似乎与神经生物学改变有关,这与早期生活压力动物模型的许多发现相似,并且可能代表了精神病理风险增加的生物学基础。临床研究正在开始探索不同类型的早期生活应激和存在的关键发育时期的潜在差异神经生物学效应,这些时期可能对特定应激源的神经生物学效应敏感。此外,在确定个体对早期生活压力的神经生物学影响的脆弱性或恢复力时,许多调节和中介因素的作用应该得到解决。这些研究的结果可能最终有助于预防现代社会中暴露于早期生活压力的儿童数量之多令人无法接受的有害神经生物学和精神病理学后果。

Pharmacotherapy for survivors of childhood trauma. 儿童创伤幸存者的药物治疗。
Pub Date : 2002-04-01 DOI: 10.1053/SCNP.2002.31792
F. Putnam, Jaclyn E. Hulsmann
Research over the past decade and a half has established the efficacy of pharmacotherapy as an important adjunctive treatment for trauma in conjunction with either cognitive behavior therapy or psychoanalytic psychotherapy. Medication is often effective in reducing post-traumatic stress symptoms as well as treating a number of commonly comorbid conditions such as depressive and anxiety disorders. The current medications of choice are the selective serotonin reuptake inhibitors (SSRI), which are beneficial for posttraumatic reexperiencing, hyperarousal, and avoidant symptoms. Other medication classes including non-SSRI antidepressants, mood stabilizers, anticonvulsants, and anti-adrenergic agents have shown efficacy for some trauma symptoms. Because beneficial responses may be slow to appear, pharmacotherapy of trauma requires a medication trial of adequate length and dose to determine effectiveness. Partial responders may require the addition of a second class of medication. Positive responders should be maintained on medication for at least 6 months after remission of acute PTSD and at least 12 months after remission of chronic PTSD. The initial successes of pharmacotherapy for trauma are spurring further research and more effective medications can be anticipated in the foreseeable future.
过去15年的研究已经确立了药物治疗作为一种重要的辅助治疗创伤的疗效,无论是与认知行为治疗或精神分析心理治疗相结合。药物治疗在减轻创伤后应激症状以及治疗一些常见的合并症,如抑郁症和焦虑症方面通常是有效的。目前的首选药物是选择性5 -羟色胺再摄取抑制剂(SSRI),它对创伤后再体验、过度觉醒和回避症状有益。其他药物包括非ssri类抗抑郁药、情绪稳定剂、抗惊厥药和抗肾上腺素能药物对一些创伤症状有疗效。由于有益的反应可能缓慢出现,创伤的药物治疗需要足够的时间和剂量的药物试验来确定有效性。部分应答者可能需要加用第二类药物。急性PTSD缓解后至少6个月,慢性PTSD缓解后至少12个月,阳性反应者应继续服药。创伤药物治疗的初步成功正在刺激进一步的研究,在可预见的未来可以预期更有效的药物。

Medication is often effective in reducing post-traumatic stress symptoms as well as treating a number of commonly comorbid conditions such as depressive and anxiety disorders. The current medications of choice are the selective serotonin reuptake inhibitors (SSRI), which are beneficial for posttraumatic reexperiencing, hyperarousal, and avoidant symptoms. Other medication classes including non-SSRI antidepressants, mood stabilizers, anticonvulsants, and anti-adrenergic agents have shown efficacy for some trauma symptoms. Because beneficial responses may be slow to appear, pharmacotherapy of trauma requires a medication trial of adequate length and dose to determine effectiveness. Partial responders may require the addition of a second class of medication. Positive responders should be maintained on medication for at least 6 months after remission of acute PTSD and at least 12 months after remission of chronic PTSD. The initial successes of pharmacotherapy for trauma are spurring further research and more effective medications can be anticipated in the foreseeable future.","PeriodicalId":79723,"journal":{"name":"Seminars in clinical neuropsychiatry","volume":"7 2 1","pages":"129-36"},"PeriodicalIF":0.0,"publicationDate":"2002-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58318209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is now clear that early experience influences the long-term development of behavioral, neuroendocrine, and cognitive systems in a number of animal species. This article examines the effects of early life stress on the development of the rodent. Postnatal maternal separation is often used as a potent early life stressor, and some of the major findings from these studies are discussed. A majority of these studies have shown that early life stress can lead to a heightened stress response when maternally deprived rodents are tested as adults. The effects of early life stress on the development of brain structures involved in regulating the stress response as adults are also discussed. Finally the influence of both genetics and maternal style are mentioned in relation to their ability to alter the effects of early life stress.
现在很清楚,在许多动物物种中,早期经验影响行为、神经内分泌和认知系统的长期发展。本文探讨了早期生活压力对啮齿动物发育的影响。产后母亲分离通常被用作一个强有力的早期生活压力源,并从这些研究的一些主要发现进行了讨论。这些研究中的大多数表明,当被剥夺母性的啮齿动物成年后接受测试时,早期生活压力会导致应激反应加剧。还讨论了早期生活压力对成年后参与调节应激反应的脑结构发育的影响。最后,遗传和母亲风格的影响都提到了它们改变早期生活压力影响的能力。
