Rising Young Adult Strokes
First-time stroke rates among young adults nearly double over three decades, study reveals

Key Points
1
The study recorded 2,076 first-ever strokes among adults ages 20 to 54 between 1993 and 2020; 35.6% occurred in Black individuals and 49.6% occurred in women.
2
The Greater Cincinnati/Northern Kentucky Stroke Study has tracked the region since 1988 and covers about 1.4 million people; researchers described the area as broadly representative of the United States in age, education and income.

Among younger stroke patients, high blood pressure rose from 47.3% to 60.3%, diabetes increased from 19.1% to 25.5%, and atrial fibrillation climbed from 1.4% to 5.9% between the early 1990s and 2020.

Researchers said the increase in documented substance use was driven substantially by marijuana: reported marijuana use rose from less than 1% of younger stroke patients in the early 1990s to 30.6% in 2020. Study co-author David Robinson cautioned that existing research has limitations and called for more rigorous studies of marijuana as a possible cardiovascular risk factor.

Study author David Robinson said stroke-related disability can make it harder for younger survivors to work or care for young children, emphasizing that stroke prevention is relevant even before older age.
Stroke rates among adults ages 20 to 54 have nearly doubled over 27 years in the Greater Cincinnati and Northern Kentucky region, jumping from 33.9 cases per 100,000 person-years in 1993-94 to 62.2 in 2020, according to Neurology. The surge defies the trend among older adults, whose stroke rates declined during the same period. A University of Cincinnati study found the increase was driven primarily by ischemic strokes—when blood clots block blood flow to the brain—and linked to rising rates of high blood pressure, diabetes, and documented drug use among younger patients.
Researchers documented 2,076 first-time strokes among younger adults between 1993 and 2020. More than one-third occurred in Black individuals, and about half occurred in women. University of Cincinnati researchers caution the study does not prove marijuana or other drugs caused the strokes, but the findings highlight a troubling health shift affecting people in their 20s through 50s when they're often working and raising children.
Why Young Adults Are Suffering More Strokes
Among younger stroke patients, documented cardiovascular risk factors climbed sharply. High blood pressure rose from 47.3% to 60.3%. Diabetes increased from 19.1% to 25.5%. Atrial fibrillation—an irregular heartbeat that can trigger clots—jumped from 1.4% to 5.9%, according to the study. These traditional risk factors alone don't fully explain the doubling of stroke rates.
Documented substance use among younger stroke patients surged from 4.6% to 40.2%. Marijuana use drove much of this increase, rising from less than 1% in the early 1990s to 30.6% in 2020. Study co-author David Robinson emphasized that existing research on marijuana and heart health has limits, and he called for more rigorous studies to understand the connection.
Strokes in Young Adults Carry Long-Term Life Costs
Younger stroke survivors face different challenges than older patients. A 30-year-old who has a stroke may spend decades managing disability while trying to work and care for children. David Robinson noted that stroke-related disability makes it harder for young survivors to hold jobs or provide childcare for young children. This underscores why stroke prevention matters in younger age groups, not just in older adults.
The study also found that more young adults are surviving initial strokes. Better emergency care and treatment options have improved survival rates. However, survivors often face lasting brain damage, speech problems, weakness on one side of the body, and cognitive difficulties that can reshape their lives and careers.
A Regional Snapshot Mirrors National Health Trends
The Greater Cincinnati and Northern Kentucky Stroke Study has tracked the region since 1988 and covers about 1.4 million people. Researchers described the area as broadly representative of the United States in age, education, and income. The findings suggest the trend may reflect national patterns, not just local conditions. The doubling of stroke rates in younger adults is a warning sign for other regions and the healthcare system overall.
