A community survey and subsequent clinical assessment of 192 Cree aged 65 years and over registered in two Reserves in Northern Manitoba identified only one case of probable Alzheimer's disease among eight cases of dementia, giving a prevalence of 0.5% for Alzheimer's disease and 4.2% for all dementias. This contrasted with an age-adjusted prevalence of 3.5% for Alzheimer's disease and 4.2% for all dementias in an age-stratified sample of 241 English-speaking residents of Winnipeg. Although it was not so for all dementias, the difference between the groups for prevalence of Alzheimer's disease was highly significant (p < .001). The age-specific patterns of all dementias in the two groups were significantly different, however (p = .0254).
一项针对在马尼托巴省北部两个保留地登记的192名65岁及以上克里族居民的社区调查及后续临床评估发现，在8例痴呆病例中仅1例可能为阿尔茨海默病，阿尔茨海默病患病率为0.5%，所有痴呆症患病率为4.2%。相比之下，在温尼伯市241名讲英语居民的年龄分层样本中，经年龄调整后的阿尔茨海默病患病率为3.5%，所有痴呆症患病率为4.2%。虽然并非所有痴呆症都是如此，但两组之间阿尔茨海默病患病率的差异非常显著（p <.001）。然而，两组中所有痴呆症的年龄特异性模式存在显著差异（p = 0.0254）。
