AnnotationThe relationship between ageing and the prevalence of dementia and the ratio of Alzheimer's disease (AD) to vascular dementia (VD) was investigated in 4,368 Japanese over 60s. The authors also set out to understand the features of early onset dementia as seen in patients from 60 to 65, and to examine recognition of dementia by family members. Prevalence of dementia in these over 60s was 6.2% (men: 5.9%; women: 6.8%); the prevalence increased with age. The AD/VD ratio was 1.4 and was similar to the recent trend in Japan in that the ratio has reversed to resemble the western pattern. With regard to families' recognition of illness, the higher the severity of dementia, the higher the recognition ratio of family members became. Only half these subjects were recognised as having dementia by their family members. Westernisation of the AD/VD ratio was proved. (RH).
