Abstract:
Focal atrophy of the left anterior temporal lobe has been associated with the semantic type of primary progressive aphasia evolving to semantic dementia. In contrast, focal atrophy of the right temporal lobe has more recently been described as a controverse entity reported as the right temporal variant of FTD. We describe two cases of FTD dementia syndromes: in Case 1, atrophy of the right temporal lobe led to significant behavioural impairment and difficulties in recognizing known people. In Case 2, atrophy of the left temporal lobe was associated with severe aggressive, ritualistic behaviour and aphasia.
摘要:
左颞叶的局灶性萎缩与原发性进行性失语症的语义类型演变为语义性痴呆有关。相比之下,最近,右颞叶的局灶性萎缩被描述为有争议的实体,被报道为FTD的右颞叶变体。我们描述了两例FTD痴呆综合征:在病例1中,右颞叶萎缩导致严重的行为损害和识别已知人群的困难。在病例2中,左侧颞叶萎缩与严重侵袭性相关,仪式行为和失语。
