丘脑血管病的神经心理学研究

本文报告了18例经CT扫描诊断为单侧丘脑血管病患者,于发病2～4周内进行失语症及记忆测验:结构、运用及计算等检查。2/3患者有失语,约半数出现近记忆、计算及摆方块障碍,约1/3患者出现手指失认、左右失认等Gertmano's综合征表现。讨论了丘脑性失语的特点,认为这是一种独立失语类型。指出丘脑语言优势多为左侧,右侧亦存有语言功能,少数人可为优势侧。丘脑病变导致的近记忆、计数、结构等心理学障碍与言语障碍程度及演变不呈平行关系。本研究为中风患者临床诊断和康复治疗标准提供客观依据。

A Neuropsychologic Study on Vascular Disease of Thalamus

Eighteen patients with unilateral thalamic vascular disease confirmed by CT scans were reported in this article. Aphasia, memory, constructional, apraxia and calculative tests were performed in all of the patients during two to four weeks after onset. The results showed that 12 cases had aphasia, 9 retroactive amnesia, 10 acalculia and 7 difficulty in figuresmaking. One-third of the cases presented Gerstmann's syndrome including finger agnosia, left-right confusion and so on. It was considered that thalamic aphasia is a special type, and the dominant linguistic side of the thalamus is usually on the left although the right thalamus has some linguistic functions, and only in a few people is the dominant side on the right. Retroactive amnesia, acalculia and difficulty in figuresmaking caused by thalamic disorders are not parallel to the degree of aphasia and development.This study provided an objective index for the clinical diagnosis and rehabilitation of the patients with thalamic vascular disease.
