Abstract
Age-specific death-rate curves for Parkinson's disease in Norway for 1970 to 1974 and 1980 to 1985 were very similar in configuration to those at like periods in the United States and Denmark. As with the United States and Denmark, the pattern of a steady, progressive increase with age in the 1980s reverted to the earlier configurations, which showed maximal rates near ages 80, when the Norwegian rates were recalculated by attributing all deaths to ages 5 years younger.
