Childhood sexual abuse (CSA) is associated with autobiographical memory (AM) disturbances. AM is important for future thinking, sense of self, and coping with negative emotions. CSA is under-researched among men, with research examining long-term neural correlates limited even further. This study explored the neural correlates of re-experiencing traumatic/negative memories to examine the influence of CSA on AM into adulthood. Fifteen males who experienced CSA, with and without posttraumatic stress disorder (PTSD; CSA+PTSD, = 6; CSA-PTSD, = 9) and control males without CSA histories nor PTSD ( = 11) completed a script-driven imagery paradigm during functional magnetic resonance imaging (fMRI). Males with CSA histories, with and without PTSD, processed their negative autobiographical memories with less activation compared to control males. The CSA+PTSD group of males had less activation in the left superior occipital, left superior parietal and left parahippocampal gyri compared to control participants. The CSA-PTSD group had reduced activation in the same regions to a lesser extent. This study provides preliminary empirical evidence to suggest CSA impacts AM for traumatic experiences, and the impact is notable even for men who experienced CSA but do not have PTSD. This study highlights the need for more research with men who have experienced CSA, so that, we can fully understand the neural correlates of emotional memories, and better support the mental health and continued wellness of men who experienced CSA.
儿童期性虐待(CSA)与自传体记忆(AM)障碍有关。AM 对未来思维、自我意识和应对负面情绪很重要。CSA 在男性中的研究不足,甚至进一步限制了对长期神经相关性的研究。本研究探讨了重新体验创伤/负面记忆的神经相关性,以研究 CSA 对成年后 AM 的影响。15 名经历过 CSA 的男性(伴有或不伴有创伤后应激障碍(PTSD);CSA+PTSD,n=6;CSA-PTSD,n=9)和没有 CSA 史和 PTSD 的对照组男性(n=11)完成了功能磁共振成像(fMRI)期间的脚本驱动意象范式。与对照组男性相比,有 CSA 史和 PTSD 的男性对负面自传体记忆的处理激活程度较低。与对照组参与者相比,CSA+PTSD 组男性的左侧顶枕上回、左侧顶上回和左侧海马旁回的激活程度较低。CSA-PTSD 组在这些区域的激活程度较低。本研究提供了初步的实证证据,表明 CSA 会影响创伤体验的 AM,即使是经历过 CSA 但没有 PTSD 的男性,其影响也很明显。本研究强调了需要对经历过 CSA 的男性进行更多的研究,以便我们能够充分了解情绪记忆的神经相关性,并更好地支持经历过 CSA 的男性的心理健康和持续健康。
