BACKGROUND: The average life expectancy of a person aged 75 in Finland is approximately 10 years. A substantial threat to the quality of life during these years is stroke, which is common among the elderly, may hamper independent living and places a substantial burden on health care resources. The aim of the present study was to analyse the trends in incidence, mortality and prognosis of acute stroke events in persons aged > or = 75 years in Finland. DESIGN: A population-based stroke register study. METHODS: The FINSTROKE register recorded all stroke events in persons aged > or = 75 years (n=5493) among inhabitants of the town of Turku from 1982 to 1992 and again from 1996 to 1998, and in the Kuopio area from 1990 to 1997. RESULTS: At the end of the study period, the age group > or = 75 years constituted 3.8% of the population of study areas among men and 8.7% among women. This population segment contributed 35% of strokes among men and 66% among women. Of all strokes in this age group, 73% occurred among women. Data suggested that the mortality and incidence of acute stroke events were declining, but the 28-day case fatality did not change. At day 28 after the onset of stroke, only 26% of men and 19% of women had recovered well enough to be capable of independent living. CONCLUSIONS: Stroke mortality among the elderly is declining in Finland, which is mainly due to the decline in the incidence of stroke events.
