Stroke is often thought of as something that happens to people in their 70s and 80s. But a growing number of people in their 30s, 40s and early 50s are having strokes too. A study spanning nearly three decades found stroke rates in younger adults rose by more than 80% even as rates fell in older age groups. Many of the risk factors behind the rise can be checked and controlled.
Key Takeaways
- The rate of first strokes among adults 20 to 54 rose about 83% between 1993 and 2020 in the Greater Cincinnati and Northern Kentucky region. The study was published in Neurology in September 2026.
- Ischemic strokes, caused by a blocked blood vessel in the brain, nearly doubled and accounted for most of the increase.
- High blood pressure, diabetes, atrial fibrillation and substance use all became more common among younger stroke patients during this time.
- There was good news, too: younger adults became less likely to die within 30 days of a stroke.
- Most strokes are linked to risk factors that can be controlled, and checking your blood pressure is one of the most important steps.
What the study found
Researchers at the University of Cincinnati analyzed more than 2,000 first strokes in adults aged 20 to 54 who were treated at hospitals across the Greater Cincinnati and Northern Kentucky area. Stroke cases in the region have been tracked for decades as part of the long-running Greater Cincinnati/Northern Kentucky Stroke Study.
They compared stroke rates in six periods between 1993 and 2020:
- All strokes rose from 33.9 to 62.2 per 100,000 younger adults each year.
- Ischemic strokes rose from 23.8 to 47.3 per 100,000, nearly doubling.
- Bleeding strokes (hemorrhagic strokes) didn’t show a similar rise.
During the same period, overall stroke rates in the region went down, largely because older adults have benefited from better blood pressure and cholesterol control.
The study also found that the share of younger stroke patients with documented substance use rose from about 5% to 40%, mostly involving marijuana. Researchers say it’s not clear how much cannabis itself contributed. Stimulants like cocaine and methamphetamine have stronger, well-established links to stroke.
Survival improved over time. The share of younger stroke patients who died within 30 days fell from about 12% to 9%.
Why strokes are rising in younger adults
The study couldn’t prove what’s driving the increase, but researchers and outside experts point to several likely factors:
- High blood pressure: It’s the single strongest risk factor for stroke, and it’s becoming more common in younger adults. Many don’t know they have it, because it usually causes no symptoms.
- Diabetes and obesity: Both damage blood vessels over time and are rising in people under 55.
- Atrial fibrillation: This irregular heart rhythm can cause blood clots that travel to the brain. It’s increasingly being diagnosed in younger people.
- Substance use: Stimulants and heavy drug use can raise blood pressure sharply or narrow blood vessels.
- Less physical activity: More time sitting is linked to many of the conditions above.
The limits of the study
The data came from one region, so the results may not reflect the entire country. And because the study didn’t compare stroke patients with people who didn’t have strokes, it can’t show how much each risk factor contributed to the rise.
The researchers say more work is needed to understand what’s driving the trend and how to reverse it.
How to lower your stroke risk, at any age
The study’s senior author recommends following the American Heart Association’s “Life’s Essential 8,” a checklist for heart and brain health:
- Know your blood pressure. Get it checked at least once a year, or more often if it’s elevated. A home monitor can help.
- Check your blood sugar and cholesterol, especially if you have a family history of diabetes or heart disease.
- Move more. Aim for at least 150 minutes of moderate activity, such as brisk walking, each week.
- Eat a heart-healthy diet rich in vegetables, fruits, whole grains, beans, nuts and fish, and limit salt and ultra-processed foods.
- Don’t smoke or vape, and avoid stimulant drugs.
- Get 7 to 9 hours of sleep a night. Ask about sleep apnea if you snore loudly or wake up tired.
- Maintain a healthy weight.
- Mention heart palpitations to your doctor. A racing or fluttering heartbeat could be a sign of atrial fibrillation.
Know the warning signs
Strokes in younger adults are sometimes dismissed as migraines, vertigo or stress, which can delay treatment. Remember BE FAST:
- Balance: Sudden loss of balance or dizziness
- Eyes: Sudden vision loss or blurry vision
- Face: One side of the face drooping
- Arms: Weakness or numbness in one arm
- Speech: Slurred or confused speech
- Time: Call 911 right away
Treatment works best in the first few hours, so don’t wait to see if symptoms go away, no matter how young you are.
This isn’t a substitute for medical advice. Talk to your doctor about your stroke risk.
