The incidence rate of death by stroke has declined among older adults
There are fewer people dying from strokes across nearly all age ranges, according to new research by the American Academy of Neurology.
Published in Neurology, the findings described a decrease of intracerebral hemorrhage and ischemic stroke in older adults.
Between 2005 and 2018, close to 9,000 adults in early to mid-adulthood, and nearly 105,000 in late-adulthood, were examined as part of a national health care registries in Denmark. All of the participants had a history of strokes.
Incidence rates were calculated based on annual statistics racked from the Danish population, focusing only on hemorrhagic and ischemic strokes.
“Researchers found the incidence rate of stroke in people 49 and younger remained steady over the course of the study, with around 21 cases of ischemic stroke per 100,000 person-years at the start and end of the study,” a news release of the findings state.
“Person-years take into account both the number of people in the study and the amount of time each person spends in the study. For intracerebral hemorrhage, the incidence rate in young people was around 2 cases per 100,000 person-years at the start and end of the study,” the news release also infers.
Over the span of the study, it was determined that incidence rates of strokes decreased among the participants aged 50 and over.
There were 372 cases of ischemic stroke per 100,000 person-years at the beginning of the study, with 311 cases at the end, researchers found. “For intracerebral hemorrhage, there were 49 cases per 100,000 person-years at the start of the study and 38 cases at the end. However, stroke rates in people in their 50s were stable, with most of the decline in people age 70 and older,” the news release also mentioned.
