BACKGROUND: Successive elderly birth cohorts improved in cognitive performance during the 20th century. It is not clear whether this influences cognitive predictors of dementia and mortality. OBJECTIVE: In 2 longitudinal population studies, representing 2 cohorts of 70-year-olds examined 30 years apart, we investigated the relation between baseline cognitive function and 5-year occurrence of dementia and mortality. METHODS: Two representative cohorts

BACKGROUND: Few studies have examined whether cognitive symptom patterns differ by age and length of time before dementia onset. Our objective was to investigate whether different patterns of cognitive symptoms at ages 70, 75, and 79 years predict short-term (< or =5 years) and long-term (>5 years) dementia onset. METHODS: A representative sample of 382 nondemented 70-year-olds from Gothenburg, Sweden was examined periodically up to age 90 years.

Objective: To evaluate the utility of assessing four cognitive domains obtained from four information sources to identify individuals at risk for developing dementia, Alzheimer disease (AD), and vascular dementia (VaD). Methods: A representative population sample of nondemented 85-year-olds (n=313) from Gothenburg, Sweden, was examined regarding memory, language, and visuospatial and executive functions, using self- and key informant reports and
