Stroke Strikes Productive Age: Cases Double in Three Decades

The incidence of stroke among young adults in the United States shows a worrying trend. A long-term study led by researchers from the University of Cincinnati, Ohio, found that although overall stroke cases declined, the proportion of stroke patients in the 20 to 54 age group doubled over 27 years. The findings were published in the latest issue of the journal Neurology.

The study, which analyzed data from the Greater Cincinnati and Northern Kentucky region, compared six time periods: July 1993–June 1994, as well as 1999, 2005, 2010, 2015, and 2020. As a result, in the young age group, stroke incidence rose from 33.9 cases per 100,000 person-years in 1993-1994 to 62.2 cases per 100,000 person-years in 2020. Most were ischemic strokes, which surged from 23.8 to 47.3 cases per 100,000 person-years.

David Robinson, MD, senior author of the study and assistant professor in the Department of Neurology and Rehabilitation Medicine at the University of Cincinnati, explained that the overall decline in stroke rates is the result of public health efforts that deserve appreciation. However, he highlighted a worrying demographic shift. "We observed a clear decline in the total number of stroke patients, but the people having strokes are getting younger," he told Medical News Today. Robinson added that death certificate data in the US also show stroke is increasingly recorded as a cause of death at younger ages, although interpretation is complicated because it could be influenced by changes in how certificates are filled out or by stroke severity.

According to Robinson, there is no single cause behind this phenomenon. "There is no doubt that some traditional stroke risk factors are increasing in young adults, including high blood pressure and diabetes," he said. He also cited obesity and sedentary lifestyles that have become more common over the past three decades, as well as increased use of illicit substances—especially marijuana—as factors that may contribute. "There is evidence that marijuana can increase stroke risk, but it is still unclear whether it is strong enough as an independent risk factor," he added.

"Prevention is really the best tool we have. If I had to recommend one thing, it would be to look for opportunities to screen for high blood pressure, which is often asymptomatic in its early stages and can cause a lot of damage before it is diagnosed." — David Robinson, MD

Echoing Robinson, Walavan Sivakumar, MD, a board-certified neurosurgeon and director of neurosurgery at Providence Little Company of Mary, California, who was not involved in the study, assessed that the rise in stroke among young adults is multifactorial. He highlighted the increase in diagnoses of hypertension, diabetes, and atrial fibrillation in this age group. "These conditions are increasingly being diagnosed in young adults and can significantly increase stroke risk," he explained. Sivakumar also highlighted patterns of marijuana and stimulant use such as cocaine or methamphetamine, which have stronger links to stroke. "Although this association does not prove that marijuana causes stroke, the pattern warrants further investigation," he stressed.

Both Robinson and Sivakumar recommend concrete preventive steps. Robinson suggested following the American Heart Association's "Life's Essential 8" guidelines, which include controlling blood pressure, avoiding tobacco, eating a healthy diet, getting enough sleep, controlling blood sugar and cholesterol, managing weight, and staying active. Sivakumar added the importance of checking blood pressure and blood sugar regularly, as well as having open discussions with a doctor about substance use, including marijuana and stimulants. "People who experience palpitations or have a family history of heart rhythm disorders should consider evaluation for atrial fibrillation," he said. He also reminded everyone to recognize stroke signs such as facial drooping, arm weakness, or difficulty speaking, which require immediate medical attention regardless of age.

The study highlights the need for further research to understand why cardiovascular risk factors are increasingly common in young adults and how much each factor contributes. Sivakumar assessed that investigations into the rise in atrial fibrillation and cardioembolic stroke at young ages are also important. "Understanding whether early screening can identify at-risk individuals before a stroke occurs would have major implications for prevention," he said. Going forward, the question is whether early intervention on modifiable risk factors can reverse this trend, especially in countries with large young populations such as Indonesia.

For Indonesia, these findings are a serious warning. With a high prevalence of hypertension and increasingly inactive lifestyles in urban areas, the productive age group is at risk of a similar surge in stroke. More aggressive promotive and preventive efforts are needed, including routine screening in workplaces and awareness campaigns on the importance of early detection. Without concrete steps, the economic and social burden of stroke at productive ages could become a time bomb for the national health system.
