Stroke incidence rises 83% among young adults in US study

A study published in the journal Neurology indicates a significant rise in stroke incidence among adults aged 20 to 54. Research conducted by University of Cincinnati scientists, covering the Cincinnati and Northern Kentucky regions from 1993 to 2020, shows that the rate increased from 33.9 to 62.2 cases per 100,000 person-years, representing an approximately 83 percent increase.

The surge is primarily driven by ischemic strokes, which occur when blood vessels supplying the brain become obstructed. While ischemic stroke rates nearly doubled, hemorrhagic stroke rates did not show a similar increase.

Key contributing risk factors identified in younger patients include hypertension, diabetes, atrial fibrillation, and substance use. Specifically, the proportion of patients reporting substance use—largely involving marijuana—rose from 4.6 percent to 40.2 percent. Medical experts emphasize that while 30-day mortality rates have slightly decreased, more young people are living with long-term consequences such as impaired movement, speech, or memory. Prevention through managing blood pressure, cholesterol, and lifestyle factors remains critical.
