Current theories assume that retrograde memory deficits for semantic information in amnestic mild cognitive impairment (aMCI) are temporally graded and partially sparing most remote memories. Moreover, these models assume a prevalent role of the hippocampus in early phases of memory consolidation and of the prefrontal mesial neocortical areas in permanent consolidation of traces.

遗忘性轻度认知障碍中公共事件的记忆：海马和腹内侧前额叶皮层的作用

目前的理论假设遗忘性轻度认知障碍 (aMCI) 中语义信息的逆行记忆缺陷是暂时分级的，并且部分保留了大多数远程记忆。此外，这些模型假设海马在记忆巩固的早期阶段和前额叶内侧新皮质区域在痕迹的永久巩固中发挥普遍作用。
