脑梗塞后失语性失写的神经心理学特点

Neuropsychological features of aphasic agraphia after cerebral infarction

为了探讨失语性失写的机制和神经基础，选择20例脑梗塞后失语性失写患者作为观察对象。失写特点有构字障碍、字词错写和语法错误。双侧大脑半球大部分区域，尤其是左侧，均与失语性失写有关。这与大多数人的言语功能强烈依靠左侧大脑半球，同时右半球在言语的某些方面也有活动力的结论相一致。

To explore the mechanisms and neurological basis of aphasic agraphia,20 patients with aphasic agraphia after cerebral infarction were selected for observation. The agraphic features showed orthographic disorders,lexical errors and grammar errors. The aphasic agraphia was related to most parts of the cerebral hemispheres,especially the left one. This finding is consistent with that the language ability of most pepole depends on the left hemisphere,and on the right one also on some aspects.
