... (mean age: 72 years, 58% women), to compare participant characteristics, predicted risk of cardiovascular disease, and dementia risk, between trial eligible and ineligible persons. Results: We identified 10 trials, of which 5 had been published (DR’s EXTRA, FINGER, preDIVA, MAPT, and HATICE) and 5...

... status are all unclear. Methods: From the Medical Research Council National Survey of Health and Development, we analysed 3,192 participants undergoing one or more cognitive assessments at ages 43, 53, 60–64 and 69. Linear mixed models described cognitive trajectories, adjusting for factors across...

... to be associated with statistically significant increases in MDS-UPDRS Part III scores. For every 10-year increase in age, the Part III score was greater on average by 2.2 (1.5-2.8). Conclusions: Elevated MDS-UPDRS scores are common in the general population. The overall burden of motor signs of parkinsonism...

... in epidemiologic studies of early old-age populations presents a methodological challenge, given the broad range of variability in cognitive functioning in this age group. Objectives: (1) To provide data on the distribution of cognitive performance scores in a representative sample of an early old-age population...

... population of Novosibirsk (Russia) and 6 cities of the Czech Republic recruited random samples of men and women (3,874 Russians, 3,626 Czechs) aged 45–69 years in 2002 (i.e. born in 1933–1957). Word recall, verbal fluency (number of animals named in 1 min) and letter search were assessed in a clinic. Results...

..., which makes a distinction between physiological and pathophysiological ageing difficult. We studied the relation between cerebral haemodynamic parameters and age and sex in 1,720 participants of a population-based study by means of transcranial Doppler ultrasonography. The end-diastolic, peak systolic...

... Objective: To describe the baseline characteristics of the participants in the Three-City (3C) Study, a study aiming to evaluate the risk of dementia and cognitive impairment attributable to vascular factors. Methods: Between 1999 and 2001, 9,693 persons aged 65 years and over...

...C. Chadwick The purpose of this paper is to describe the design and methodology of this multicentre study of cognitive function and ageing, which is currently funded by the Medical Research Council (MRC) and the Department of Health for a period of 5 years. The study is designed to estimate...
