| Annotation | Above age 65, the prevalence of dementia rises exponentially from 1% to 15% at age 85. Despite many studies concerning dementia, little is known about the prevalence of dementia in the "oldest old". Whether the prevalence levels off around age 95 is yet unanswered, although recent studies postulate a plateau value of 40%-45% at that age. This question is important because it addresses whether dementia is an inevitable consequence of ageing or a disorder occurring within a specific age range. All 17 people aged 100 and over in three Dutch towns with 250,000 inhabitants were examined by means of cognitive tests, informant questionnaires, clinical interviews and anamneses. Fifteen of the 17 Dutch centenarians were found to be demented; and two could not be examined. This very high prevalence of dementia in a complete sample of centenarians strongly suggests that we will all become demented if we live to our maximum life span potential. (RH). |
