Stroke rates nearly doubled among adults 20 to 54 in Cincinnati region since 1990s

A recent study has found that the rate of strokes among adults aged 20 to 54 in the Greater Cincinnati and Northern Kentucky region nearly doubled from 1993 to 2020. Led by researcher Emily R. Fisher of the University of Cincinnati, the investigation revealed that ischemic strokes, caused by blocked blood flow to the brain, saw the most significant rise, increasing from 23.8 to 47.3 cases per 100,000 person-years during the same period.

In contrast, other types of strokes, such as intracerebral hemorrhage and subarachnoid hemorrhage, did not exhibit similar increases.

While the overall 30-day death rate after stroke slightly declined, this improvement was largely seen among people with intracerebral and subarachnoid hemorrhage. However, the study's findings highlight a concerning trend: risk factors associated with stroke, such as high blood pressure, diabetes, atrial fibrillation, and substance use (particularly marijuana), became more common among younger adults who experienced a stroke.

The proportion of younger adults with stroke who had substance use issues increased dramatically from 4.6% in 1993-94 to 40.2% in 2020.

The study emphasizes the importance of identifying and managing stroke risk factors early in adulthood. However, more research is needed to understand the driving forces behind these rising trends and potential ways to reverse them. One limitation of the study is that it lacked comparable data for people without stroke, making it difficult to determine whether observed risk factors fully explain the increase in stroke rates.
