In 58 patients with progressive supranuclear palsy (PSP), 19 (32.8%) had CT, MRI, or autopsy evidence of a multi-infarct (MI) state. The clinical findings in the infarct syndrome were similar to idiopathic PSP. Five MI-PSP patients had had a stroke, four had focal dystonia, two had hemiparesis, and one had an intention tremor of recent onset. In contrast, only 5.9% (12.9% of those with CT or MRI) of 426 Parkinson's disease patients had evidence of strokes. One case of PSP studied pathologically was attributed to cerebral amyloid angiopathy.
在58例进行性核上性麻痹（PSP）患者中，19例（32.8%）有CT、MRI或尸检证据显示存在多发性梗死（MI）状态。梗死综合征的临床发现与特发性PSP相似。5例MI-PSP患者曾发生过中风，4例有局灶性肌张力障碍，2例有偏瘫，1例有近期出现的意向性震颤。相比之下，426例帕金森病患者中只有5.9%（CT或MRI检查患者中的12.9%）有中风证据。经病理研究的1例PSP病例归因于脑淀粉样血管病。
