Stroke Cases Nearly Double Among Young U.S. Adults
A study looked at strokes in people aged 20 to 54 in the Greater Cincinnati area.
It examined six periods between 1993 and 2020.
The study found that strokes in younger adults became much more common.
Most of the increase came from ischemic strokes, which happen when blood flow to the brain is blocked.
Health problems such as high blood pressure and diabetes were more common among people who had strokes.
The good news is that fewer young adults died within 30 days after having a stroke.
However, more survivors may live with long-term effects.
Researchers say that finding and treating stroke risks early may help reverse the trend.
A University of Cincinnati study found first-time strokes among adults aged 20–54 nearly doubled from 1993–94 to 2020.
Young-adult stroke incidence rose from 33.9 to 62.18 cases per 100,000 people over the study period.
Ischemic stroke incidence nearly doubled, increasing from 23.8 to 47.3 cases per 100,000 people.
Hypertension, diabetes, atrial fibrillation, and substance use became more common among young adults who had strokes.
Thirty-day case-fatality rates among young adults declined from 11.7% in 1993–94 to 9.4% in 2020.
- Who
- Researchers led by Emily R. Fisher at the University of Cincinnati studied adults aged 20–54 who experienced first-time strokes.
- What
- The study found that stroke incidence among young adults nearly doubled, while 30-day case-fatality rates declined.
- When
- The study covered July 1993–June 1994 and the calendar years 1999, 2005, 2010, 2015, and 2020; it was published September 23.
- Where
- A five-county region in Greater Cincinnati, United States.
- Why
- Researchers said the findings highlight the need to identify and manage stroke risk factors early in adulthood, while noting that more research is needed to explain the trend.
