Abstract:
A Vietnam veteran with a combat-related posttraumatic stress disorder developed recurrent dissociative flashbacks (related to the atrocities of a specific war incident) several months after suffering a traumatic brain injury. CT disclosed a small lesion in the right dorsolateral prefrontal cortex. SPECT demonstrated more extensive functional changes in prefrontal and anterior paralimbic brain regions, mainly in the right hemisphere. This case further implicates the provocative effect of physical stimuli (brain damage) in reawakening old dormant memories and the preferential role of the right hemisphere for the storage of traumatic memories.
