This case study describes post-traumatic stress disorder (PTSD) and head injury after a road traffic accident involving a pedestrian. Previous studies have proposed two mechanisms by which this dual diagnosis may occur: (1) when post-traumatic amnesia and retrograde amnesia are small or non-existent and (2) when non-declarative memory systems for the traumatic event are in operation. This case study demonstrates a third mechanism--"islands" of memory within post-traumatic amnesia.
本案例研究描述了一起涉及行人的道路交通事故后发生的创伤后应激障碍（PTSD）和头部损伤。先前的研究提出了这种双重诊断可能出现的两种机制：（1）创伤后遗忘症和逆行性遗忘症轻微或不存在时；（2）创伤事件的非陈述性记忆系统起作用时。本案例研究展示了第三种机制——创伤后遗忘症中的记忆“孤岛”。
