To determine the association between the e4 allele of apolipoprotein E and Alzheimer's disease in a randomly selected population sample.
Cross sectional population based study.
980 people aged 69 to 78 (349 men, 631 women).
Population of Kuopio, eastern Finland.
Presence of e4 allele and diagnosis of Alzheimer's disease by detailed neurological and neurophysiological evaluation.
46 (4.7%) subjects were classified as having probable or possible Alzheimer's disease. The frequency of the apolipoprotein E e4 allele was 0.359 in patients with Alzheimer's disease and 0.165 subjects without dementia (P < 0.0001). The prevalence of Alzheimer's disease was 2.9% in subjects with no e4 alleles, 7.6% in subjects with one e4 allele, and 21.4% in subjects with two e4 alleles of apolipoprotein E.
Allele e4 of apolipoprotein is associated with Alzheimer's disease in a dose-response fashion in a randomly selected elderly population.
在一个随机抽取的人群样本中确定载脂蛋白E的e4等位基因与阿尔茨海默病之间的关联。
基于人群的横断面研究。
980名年龄在69至78岁之间的人(349名男性,631名女性)。
芬兰东部库奥皮奥的人群。
通过详细的神经学和神经生理学评估确定e4等位基因的存在以及阿尔茨海默病的诊断。
46名(4.7%)受试者被归类为可能患有或疑似患有阿尔茨海默病。阿尔茨海默病患者中载脂蛋白E e4等位基因的频率为0.359,无痴呆症的受试者中该频率为0.165(P < 0.0001)。在没有e4等位基因的受试者中,阿尔茨海默病的患病率为2.9%,在有一个e4等位基因的受试者中为7.6%,在有两个载脂蛋白E e4等位基因的受试者中为21.4%。
在一个随机抽取的老年人群中,载脂蛋白的e4等位基因与阿尔茨海默病呈剂量反应关系。
