The prevalence of dementia over age 100

R. Thomassen, H.W. van Schaick, B.A. Blansjaar

All nine persons aged 100 or more in a Dutch town with some 100.000 inhabitants were examined by means of cognitive tests, informant questionnaires and clinical interviews. Formal testing was difficult in most subjects because of visual, auditory and motor handicaps. By combining the results of cognitive tests, questionnaires and clinical examination a diagnosis of moderate to severe dementia could be made in eight subjects. One subject was not examined, but by informant questionnaire found to be mildly impaired.
