中央前回皮层下白质 SWM
DAI最常累及的部位：皮层下白质区、胼胝体(尤其是压部)、放射冠、内囊、脑干背外侧。
The areas most commonly involved in DAI are the subcortical white matter, corpus callosum (especially splenium), corona radiata, internal capsule, and the dorsolateral aspect of the upper brainstem.
缺血后脑的病理改变以神经细胞变性、固缩和退变，皮层下白质的神经纤维和髓鞘溃变为主，普遍存在胶质细胞增生，形成胶质小结。
There were obvious pathological change in the brain after the chronic cerebral hypoperfusion, such as myelinic degeneration and formation of glial nodule in white matter.
