Highlights from the 25th Annual International Stroke Conference
Several investigative groups provided more accurate estimates of the total incidence rates and burden of stroke in the United States and the world at the 25th International Stroke Conference. In a population-based study in Rochester, Minnesota, Brown and colleagues from the Mayo Clinic found that first strokes accounted for 71% and recurrent stroke for 29% of all strokes. Alarmingly, the decades-long decline in stroke incidence rates in Rochester plateaued in 1980, and from 1980 to 1994 no further progress was made in reducing stroke incidence. From July 1993 to the end of June 1994, Miller and associates from the University of Cincinnati performed a population-based study to determine the number of patients who have transient ischemic attack (TIA) and ischemic stroke and are managed solely as outpatients. This trend leads to an underestimation of stroke incidence when hospital-based models are used. They found that 51% of TIA and ischemic stroke patients were never admitted to hospital. Vermeer and colleagues, from the Rotterdam Stroke Study, examined the prevalence of silent brain infarctions on magnetic resonance imaging scans in 1077 members of a generally healthy, population-based cohort. Silent brain infarctions were present in 11% of the population and were more common in the elderly and in men.
