The relationship between recovery from aphasia and regional cerebral blood flow (CBF) was compared in 87 patients, 44 with cerebral hemorrhage and 43 with non-embolic cerebral infarction. CBF values correlated poorly with aphasia outcome in patients with cerebral hemorrhage whereas a tight correlation was demonstrated in patients with non-embolic cerebral infarction. A marked variability of CBF values in the acute and subacute stage might account for the poor correlation between CBF and aphasia outcome in patients with cerebral hemorrhage. On the other hand, a sharp discrimination was achieved between those with a good recovery from aphasia and those with a poor recovery by the dimensions of the hematoma on CT. In non-embolic cerebral infarction, a relative frontal ischemia was associated with motor aphasia while a relative temporal ischemia was associated with sensory aphasia. This dichotomy was not demonstrated in the regional CBF values in patients with cerebral hemorrhage.
对87例患者（44例脑出血患者和43例非栓塞性脑梗死患者）失语恢复情况与局部脑血流量（CBF）之间的关系进行了比较。脑出血患者的CBF值与失语预后的相关性较差，而非栓塞性脑梗死患者则显示出紧密的相关性。急性和亚急性期CBF值的显著变异性可能是脑出血患者CBF与失语预后相关性较差的原因。另一方面，通过CT上血肿的大小，可明确区分失语恢复良好者和恢复较差者。在非栓塞性脑梗死中，相对额叶缺血与运动性失语相关，而相对颞叶缺血与感觉性失语相关。脑出血患者的局部CBF值未显示出这种二分法。
