| Annotation | There are few population-based studies of centenarians and near-centenarians internationally and none in Australia to date. In the present study individuals 95 years and older were recruited from seven electoral districts in Sydney using the electoral roll, Medicare lists and multiple other strategies to obtain a representative sample. Physical and mental health and cognitive status were assessed using standard instruments in multiple sessions, with assessments individually adapted. An informant was interviewed and participants were invited to donate a blood sample, undergo an MRI scan and enrol into the brain donation programme. This study reports on preliminary data on the first 200 participants. Mean age of the sample was 97.4 years (range 95-106), with 29.5% being men and 58.5% living in a private dwelling. Rates of heart disease and diabetes were lower than in octogenarians, but hearing and visual deficits were common. The mean mini-mental state examination (MMSE) score was 21.1, with men performing better. Rates of psychological distress were low and satisfaction with life high (mean 5.91 out of a maximum of 7); 54% scored below 24 on MMSE; 39.5% were impaired on both MMSE and a functional measure; 20% had a previous diagnosis of dementia. This is a preliminary report describing the methodology of the study. It provides further evidence that dementia is not inevitable at this age and independent living is common. The study provides an excellent resource to determine the genetic and environmental contributions to long and successful cognitive ageing. (JL). |
