人的双侧大脑半球存在解剖学与功能性差异。有研究已经明确左侧大脑半球卒中和右侧大脑半球卒中存在差异,特别是在神经功能缺损、美国国立卫生研究院神经功能缺损评分( National Institutes of Health Stroke Scale, NIHSS)以及影像学检查等方面存在差异。 NIHSS评分偏重于对左侧大脑半球脑梗死评估等已经成为目前共识,但目前不同侧大脑半球对急性脑梗死的临床以及预后的具体影响仍存在着争议。“,”There is brain anatomy and function difference for the left and right hemispheres in the human brain. Numerous stud-ies have showed that there is the differences between left and right-hemispheric strokes, particularly in functional outcome, NIHSS score and imaging findings. New assement of the NIHSS toward left-hemispheric function is widely accepted. But the impact of hem-ispheric lateralization on clinical outcome is still unclear.
