We investigated the frequency of Lewy-related pathology (LRP) in the amygdala among the population-based Vantaa 85+ study. Data of amygdala samples (N = 304) immunostained with two α-synuclein antibodies (clone 42 and clone 5G4) was compared with the previously analyzed LRP and AD pathologies from other brain regions. The amygdala LRP was present in one third (33%) of subjects. Only 5% of pure AD subjects, but 85% of pure DLB subjects had LRP in the amygdala. The amygdala LRP was associated with dementia; however, the association was dependent on LRP on other brain regions, and thus was not an independent risk factor. The amygdala-predominant category was a rare (4%) and heterogeneous group.
在基于人群的万塔85岁及以上研究中，我们调查了杏仁核中路易体相关病理（LRP）的发生率。将用两种α-突触核蛋白抗体（克隆42和克隆5G4）免疫染色的杏仁核样本（N = 304）的数据与先前分析的其他脑区的LRP和AD病理进行了比较。三分之一（33%）的受试者存在杏仁核LRP。纯AD受试者中只有5%有杏仁核LRP，但纯DLB受试者中有85%有杏仁核LRP。杏仁核LRP与痴呆相关；然而，这种关联依赖于其他脑区的LRP，因此不是一个独立的危险因素。以杏仁核为主的类别是一个罕见（4%）且异质性的组。
