We report a patient with asymmetric Bálint's syndrome (predominantly right-sided oculomotor apraxia and simultanagnosia and optic ataxia for the right hemispace), and multimodal agnosia (apperceptive visual agnosia and bilateral associative tactile agnosia) with accompanying right hemianopia, bilateral agraphesthesia, hemispatial neglect, global alexia with unavailable kinesthetic reading, and lexical agraphia for kanji (Japanese morphograms), after hemorrhage in the left parieto-occipito-temporal area. The coexistence of tactile agnosia, bilateral agraphesthesia, and ineffective kinesthetic reading suggests that tactile-kinesthetic information can be interrupted because of damage to the fiber connection from the parietal lobe to the occipito-temporal area, leading to these tactually related cognitive impairments.
我们报告了一例左侧顶枕颞叶区出血后出现非对称巴尔金氏综合征(主要为右侧动眼运动性失用和同时性失认以及右侧半视野的视失认和视性共济失调)、多模态失认(知觉性视觉失认和双侧联合触觉失认),并伴有右侧偏盲、双侧失写症、半空间忽视、整体失读(动觉阅读不可用)和汉字失写症(日本形态图)。触觉失认、双侧失写症和无效动觉阅读的共存提示,由于顶叶到枕颞叶区域纤维连接的损伤,触觉-动觉信息可能会中断,从而导致这些与触觉相关的认知障碍。
