Annotation	276 Danes who had turned 100 between 1 April 1995 and 31 May 1996 were interviewed and examined at home. Prevalence of mild to severe dementia was 51%; and 31% had no signs of dementia. Among the 105 demented centenarians, 13 (12%) had diseases (vitamin B12 and folic acid deficiencies, hypothyroidism, Parkinson's disease) that could contribute to a dementia diagnosis. Of the remaining 92 participants, 46 (50%) had one or more cerebrovascular or cardiovascular diseases known to be risk factors in the development of dementia. The prevalence of these risk factors was the same in demented and non-demented participants, whereas hypertension was significantly more frequent on non-demented than demented participants. Thus, dementia is common, but not inevitable in centenarians. (RH).
