大多数临床痴呆老年患者在尸检时发现患有阿尔茨海默病、多发性梗死性痴呆、帕金森病、皮克病或克雅氏病。我们研究了5例临床特征为迟发性痴呆的患者,其大脑没有阿尔茨海默病的病理学证据,也没有任何其他特定的神经病理学诊断。我们在海马、内嗅皮质、蓝斑、黑质、丘脑底核和下橄榄中发现了嗜银颗粒、卷曲体、大量Alz-50阳性和硫代黄素S阴性的神经纤维缠结和神经纤维丝。超微结构上,颗粒、丝和缠结由直径25 nm的直管状丝状结构组成,类似于在进行性核上性麻痹患者中发现的那些,但不同于阿尔茨海默病患者的成对螺旋丝。这些结果表明,晚发性痴呆与嗜银颗粒综合征的特点也是存在的缠结和线程的地形分布进行性核上性麻痹。
Most clinically demented elderly patients are found at autopsy to have Alzheimer's disease, multi‐infarct dementia, Parkinson's disease, Pick's disease, or Creutzfeldt‐Jakob disease. We studied 5 patients clinically characterized by late onset dementia whose brains showed no pathological evidence of Alzheimer's disease, or any other specific neuropathological diagnosis. We found argyrophilic grains, coiled bodies, abundant Alz‐50‐positive and thioflavine S‐negative neurofibrillary tangles, and neuropil threads in the hippocampus, entorhinal cortex, locus ceruleus, substantia nigra, subthalamic nucleus, and inferior olives, Ultrastructurally, the grains, threads, and tangles were composed of straight tubulofilamentous structures, 25 nm in diameter, similar to those found in patients with progressive supranuclear palsy but different from the paired helical filaments of patients with Alzheimer's disease. These findings suggest that the late onset dementia with argyrophilic grains syndrome is also characterized by the presence of tangles and threads with the topographical distribution of progressive supranuclear palsy.
