Stroke Rates Among Young Adults Surge Dramatically

A recent study found that stroke incidence among young adults has more than doubled over the past three decades. Researchers at the University of Cincinnati analyzed data from 2,076 first-ever strokes among adults aged 20–54 in the Greater Cincinnati/Northern Kentucky region between 1993-1994 and 2020.

The study showed that the rate of ischemic stroke, which occurs when a blood vessel to the brain becomes blocked, increased significantly. Among younger adults who experienced strokes, there was a rise in conditions such as hypertension, diabetes, atrial fibrillation, and substance use.

Substance use, particularly marijuana, saw a sharp increase, rising from 4.6% to 40.2% in the study period. Researchers noted a relationship between marijuana use and stroke, but emphasized the need for more study to understand the full impact.

In contrast, stroke rates among older adults declined, falling from about 619 to 453 per 100,000 people annually. Short-term survival after stroke also improved, with the percentage of younger adults who died within 30 days of a stroke dropping from 11.7% to 9.4%.

The study, published in the journal Neurology on September 23, highlighted the importance of prevention, as surviving a stroke does not guarantee avoiding long-term disability. Researchers acknowledged limitations, including the lack of comparable risk factors for people without stroke and potential changes in diagnostic methods over time.

The findings were limited to five counties in one U.S. state, and researchers called for further studies to better understand the causes of the rising stroke rates among young adults.
