Mental Imagery and Post-Traumatic Stress Disorder: A Neuroimaging and Experimental Psychopathology Approach to Intrusive Memories of Trauma.

摘要: This hypothesis and theory paper presents a pragmatic framework to help bridge the clinical presentation neuroscience of intrusive memories following psychological trauma. Intrusive are hallmark symptom post-traumatic stress disorder (PTSD). However, key questions, including those involving etiology, remain. In particular, we know little about brain mechanisms involved in why only some moments trauma return as while others do not. We first present an overview patient experience neuroimaging studies that have investigated PTSD patients. Next, one mechanism how model laboratory, film paradigm, is examined. focus on combining paradigm with neuroimaging. Stemming from our current understanding processes memories, propose which memory comprises five component parts; autobiographical (trauma) memory, involuntary recall, negative emotions, attention hijacking, mental imagery. Each part considered turn, both behaviorally imaging perspective. A mapping these components onto described. Unanswered questions exist using proposed framework. Overall, suggest imagery bridging experience, recollection traumatic event. Further, by considering parts particular imagery, may be able aid development firmer between patients' experiences behind them.
