Despite the development of empirically supported treatments for posttraumatic stress disorder (PTSD), many individuals remain symptomatic following therapy or dropout prematurely. Neuroimaging studies examining PTSD treatment outcome may offer valuable insights into possible mechanisms that may impact treatment efficacy. To date, few studies of PTSD have used neuroimaging to examine symptom change following completed treatment, and most have focused on gray matter. Studies of white matter are equally important, as changes in white matter integrity (WMI) are connected to a host of detrimental outcomes. The current study examined symptom change of 21 women with PTSD as a result of interpersonal violence who received baseline diffusion tensor imaging (DTI) scans and completed 12 weeks of Cognitive Processing Therapy (CPT). After controlling for baseline PTSD severity, fractional anisotropy (FA) in the left internal capsule, posterior limb of the internal capsule, left cingulate gyrus, superior longitudinal fasciculus, and splenium of the corpus callosum was predicted by PTSD symptom change. Results contribute to understanding neural changes within therapy and may assist in predicting individual treatment response. Namely, by identifying areas potentially impacted by PTSD treatment, future studies may be able to connect the function of these white matter areas to better predict patient PTSD treatment outcome.

创伤后应激障碍的治疗结果:白质束分析

尽管对创伤后应激障碍 (PTSD) 的经验支持治疗有所发展,但许多人在治疗后仍有症状或过早退出。检查 PTSD 治疗结果的神经影像学研究可能为可能影响治疗效果的可能机制提供有价值的见解。迄今为止,很少有关于 PTSD 的研究使用神经影像学检查完成治疗后的症状变化,并且大多数研究都集中在灰质上。白质研究同样重要,因为白质完整性 (WMI) 的变化与许多有害结果有关。目前的研究检查了 21 名因人际暴力而患有 PTSD 的女性的症状变化,她们接受了基线弥散张量成像 (DTI) 扫描并完成了 12 周的认知加工治疗 (CPT)。在控制基线 PTSD 严重程度后,通过 PTSD 症状变化预测左内囊、内囊后肢、左扣带回、上纵束和胼胝体压部的分数各向异性 (FA)。结果有助于理解治疗中的神经变化,并可能有助于预测个体治疗反应。也就是说,通过识别可能受 PTSD 治疗影响的区域,未来的研究可能能够将这些白质区域的功能联系起来,以更好地预测患者 PTSD 治疗结果。结果有助于理解治疗中的神经变化,并可能有助于预测个体治疗反应。也就是说,通过识别可能受 PTSD 治疗影响的区域,未来的研究可能能够将这些白质区域的功能联系起来,以更好地预测患者 PTSD 治疗结果。结果有助于理解治疗中的神经变化,并可能有助于预测个体治疗反应。也就是说,通过识别可能受 PTSD 治疗影响的区域,未来的研究可能能够将这些白质区域的功能联系起来,以更好地预测患者 PTSD 治疗结果。
