No statistically significant differences were found in sex, age in 1991, or age at death between the whole study population and the neuropathologically examined subpopulation. CERAD = Consortium to Establish a Registry for Alzheimer’s Disease; M = moderate neuritic plaques; F = frequent neuritic plaques. SD = standard deviation.
