In this study we describe a patient, TA, who developed a chronic amnesic-confabulatory syndrome, following rupture of a right internal carotid siphon aneurysm.Our aim was to elucidate as fully as possible the nature of TA’s impairment and to test the hypothesis of confabulation as reflecting a dysfunction of Temporal Consciousness, i.e. to become aware of something as part of a personal past, present or future.TA’s confabulations were present in answers to questions tapping Temporal Consciousness, i.e. autobiographical episodicmemory, orientation in time and place, and foresight of personal future. In contrast, confabulations were not observed in answers to questions tapping Knowing Consciousness, i.e. to become aware of something as a meaning or as an element of impersonal knowledge. In fact, he had normal access to semantic knowledge, including foresight of impersonal future. TA’s brain MRI showed lesions involving the right hippocampus, parahippocampal gyrus, fornix, mammillary bodies, and thalamus. Moreover TA showed sub-cortical lesions involving the caudate and putamen nuclei bilaterally, a lesion site not commonly described in amnesic-confabulatory syndrome. We suggest that this pattern of results is better accounted for within the framework of the Memory, Consciousness and Temporality Theory and reflects a specific distortion of Temporal Consciousness.

歪曲的时间意识和保留的交谈中的知道意识：一个案例研究。

在本研究中，我们描述了一名患者 TA，他在右侧颈内动脉虹吸动脉瘤破裂后出现了慢性遗忘-胡言乱语综合征。反映了时间意识的功能障碍，即意识到某事是个人过去、现在或未来的一部分。个人未来。相比之下，在回答了解意识的问题时没有观察到虚构，即意识到某事是一种意义或非个人知识的元素。事实上，他可以正常获得语义知识，包括对非个人未来的预见。TA 的脑部 MRI 显示病变涉及右侧海马、海马旁回、穹窿、乳头体和丘脑。此外，TA 显示双侧尾状核和壳核的皮层下病变，这种病变部位在健忘症 - 混淆综合征中并不常见。我们建议在记忆、意识和时间理论的框架内更好地解释这种结果模式，并反映时间意识的特定扭曲。
