ANOSOGNOSIA

描述(调查者摘要)：没有意识到缺陷或 病感失认症通常与大脑功能障碍有关，通常 会干扰康复。不幸的是，神经心理学 与嗅觉障碍相关的机制最近知之甚少。 观察到偏瘫(感觉失认症)的无意识可由以下因素引起 WADA测试(颈动脉内注射巴比妥酸盐麻醉)。这样做的目的是 研究是使用世界反兴奋剂机构的程序来测试几个神经心理学 假设。实验I将尝试确定病感失认症是否可以 被归因于记忆缺陷。实验二将考察 病感失认症与个人忽视(失认症)的关系 并部分检验了格施温德的断网假说。实验三 将测试前馈或意向激活假说。

DESCRIPTION (Investigator's Abstract): Unawareness of a deficit or anosognosia is commonly associated with brain dysfunction and often interferes with rehabilitation. Unfortunately the neuropsychological mechanisms associated with anosognolia are poorly understood Recently we observed that unawareness of hemiplegia (anosognosia) can be induced by WADA testing (intracarotid barbiturate anesthesia). The purpose of this study is to use the wada procedure to test several neuropsychological hypotheses. Experiment I will attempt to determine if anosognosia can be attributed to a memory defect. Experiment II will examine the relationship between anosognosia and personal neglect (asomatognosia) and partially test Geschwind's disconnection hypothesis. Experiment III will test the feed forward or intention.activation hypothesis.
