摘要
创伤后应激障碍(PTSD)是唯一在诊断标准中包含惊反射改变的精神疾病。相比自我报告法,对惊反射的实验室测量与总体症状关联更紧密,并已积累了较多神经机制研究成果,可作为连接前临床与临床研究的桥梁。在惊反射应用于PTSD研究的初期,它主要作为PTSD患者高唤醒症状的客观指标,但是尚未发现惊反射强度的变化与总体症状的明确关系。近年来,惊反射与情境性焦虑、恐惧抑制等新范式结合,发现特定情境下惊反射改变是PTSD患者特有的表现。惊反射在创伤应激障碍研究中所取得的新进展对PTSD病理机制的探索和临床诊断都有所启发和推进。
Posttraumatic stress disorder （PTSD） is the only mental illness including startle response alteration in its diagnostic criteria. Compared to self-report, startle response measured in laboratory paradigm is associated more closely with overall symptom severity. There has been many research results on the neural mechanism of startle response in both humans and animals, making it possible to connect pre-clinical and clinical studies. At the beginning of using laboratory measurement of starlte response in PTSD clinical research, it has been mainly used as a specific indicator of hyperarousal symptoms, although it has not been firmly established the relation between startle alteration and overall symptoms yet. Recently, some new paradigms based on the theories of contextual anxiety or fear inhibition reveal the specific relationship of startle reflex and severity of PTSD symptom in particular contexts. The new progress in the application of startle response in PTSD will inspire and advance the discovery of pathological mechanism of PTSD and improvement of clinical diagnosis.
