Post-traumatic stress disorder (PTSD) is sometimes associated with recovered memories (RMs) of traumatic events. That is, the sufferer reports having forgotten traumatic events for a period of time, only to recall them later on. As the memories of traumatic events are recalled, post-traumatic stress disorder may emerge. The cause of recovered memories is uncertain and is the subject of debate. Some recovered memories may be reasonably accurate, while others may be ''recollections'' of imagined rather than actual events. It is unclear whether conventional PTSD therapies, such as behaviour therapy, are appropriate and effective in treating PTSD-RM. The present article considers these issues in the context of a case study, in which a patient with PTSD-RM was treated with behaviour therapy ( in vivo and imaginal exposure). The patient sought treatment because he wanted relief from his PTSD symptoms, regardless of whether his recovered memories were accurate (he was completely convinced in the accuracy of the memories). Treatment outcome was compared with the outcome of 13 PTSD patients who did not have recovered memories, who were also treated with behaviour therapy. Results suggest that PTSD-RM can be effectively treated with behaviour therapy. However, such treatment is unlikely to be appropriate for all cases of PTSD- RM. Selection criteria are discussed.
