脑出血后智力障碍与局部脑血流量相关性研究

作者用长谷川智力测定量表法测定了６１例脑出血患者的智力，用ＳＰＥＣＴ定量测定法测定了双侧大脑半球各１５个脑区的局部血流量，并计算其比值。分析了脑出血、局部脑血流量、局部脑血流量比值与长谷川分数的关系。结果提示脑出血时，除由于病变直接破坏与智力有关的结构外，左半球（特别是左颞叶及左缘上回和角回）局部脑血流量下降，缘上回和角回、颞上回后部、颞中回后部、颞下回局部脑血流量比值失衡亦可能是造成智力下降的原因。

RELATIONSHIP BETWEEN MENTAL DETERIORATION ANDREGIONAL CEREBRAL BLOOD FLOW )rCBF) FOLLOWINGCEREBRAL HEMORRHAGE

The paper reported mental change measured by Hasegawa ' s method in 61 patients with cerebral hemorrhage. The rCBFs in 15 regions for each cerebral hemisphere were measured by SPECT, and the ratio of rCBF in each region of both sides was calculated. The effects of cerebral hemorrhage, rCBF and the ratio of rCBF on Hasagawa ' s score were analyzed. The results indicated that the structures related to learning and memory were destroyed by the lesions, rCBFs decreased in the left cerebral hemisphere (especially left temporal lobe, supramarginal gyrus and langular gyrus) as well as abnormal ratios of rCBF in supramarginal gyri and angular gyri, rears of superior and middle temporal gyri, and inferior temponral gyri might be the cause of mental deterioration following cerebral hemorrhage.
