压力可能会加重强迫症(OCD)患者的强迫症状,并损害其工作记忆。本研究通过一项“数字计算工作记忆”任务,评估了压力对强迫症患者工作记忆的认知神经处理的影响及其临床意义。对38名患者以及55名性别和教育程度匹配的健康对照者进行了检查。压力损害了患者操作任务的表现。与压力较小时相比,健康对照者在压力下执行任务时内侧前额叶皮质和纹状体的参与度较低,而强迫症患者则没有这种情况。在右侧梭状回、辅助运动区、中央前回皮质和尾状核中,诊断×压力的交互作用显著。内侧前额叶皮质和纹状体抑制失败,以及右侧梭状回、辅助运动区、中央前回皮质和尾状核中与压力相关的过度激活,可能是强迫症相关的对压力的精神病理和神经反应。 本文的网络版(10.1007/s12264 - 020 - 00579 - 3)包含补充材料,可供授权用户使用。
Stress might exaggerate the compulsion and impair the working memory of patients with obsessive-compulsive disorder (OCD). This study evaluated the effect of stress on the cognitive neural processing of working memory in OCD and its clinical significance using a “number calculation working memory” task. Thirty-eight patients and 55 gender- and education-matched healthy controls were examined. Stress impaired the performance of the manipulation task in patients. Healthy controls showed less engagement of the medial prefrontal cortex and striatum during the task under stress versus less stress, which was absent in the patients with OCD. The diagnosis × stress interaction effect was significant in the right fusiform, supplementary motor area, precentral cortex and caudate. The failure of suppression of the medial prefrontal cortex and striatum and stress-related hyperactivation in the right fusiform, supplementary motor area, precentral cortex, and caudate might be an OCD-related psychopathological and neural response to stress.
