复杂性创伤后应激障碍(PTSD)表现为完全或部分PTSD的临床特征(重新经历创伤性事件,避免回忆事件,以及过度觉醒状态)以及来自三个其他集群的症状(情绪调节问题,消极的自我概念和人际关系问题)。复杂性PTSD在ICD-11中被提议作为一个新的诊断实体,通常发生在长期和复杂的创伤之后。在这里,我们简要回顾了目前的知识,复杂的创伤后应激障碍的生物学相关性,并将其与创伤后应激障碍的相关研究结果进行比较。最近的研究支持复杂的PTSD作为一个单独的诊断实体的有效性;然而,关于这种疾病的生物学基础的数据仍然非常有限。进一步的研究集中在复杂的PTSD生物学相关性和复制的初步研究结果是必要的,包括神经影像学,神经生化,遗传学和表观遗传学的调查。在复杂的PTSD中识别改变的生物学途径可能对进一步理解病理生理学和优化治疗策略至关重要。
Complex posttraumatic stress disorder (PTSD) presents with clinical features of full or partial PTSD (re-experiencing a traumatic event, avoiding reminders of the event, and a state of hyperarousal) together with symptoms from three additional clusters (problems in emotional regulation, negative self-concept, and problems in interpersonal relations). Complex PTSD is proposed as a new diagnostic entity in ICD-11 and typically occurs after prolonged and complex trauma. Here we shortly review current knowledge regarding the biological correlates of complex PTSD and compare it to the relevant findings in PTSD. Recent studies provide support to the validity of complex PTSD as a separate diagnostic entity; however, data regarding the biological basis of the disorder are still very limited at this time. Further studies focused on complex PTSD biological correlates and replication of the initial findings are needed, including neuroimaging, neurobiochemical, genetic, and epigenetic investigations. Identification of altered biological pathways in complex PTSD may be critical to further understand the pathophysiology and optimize treatment strategies.
