Stroke incidence among young adults has more than doubled over three decades, with significant increases in ischemic stroke and substance use, according to a recent study from the University of Cincinnati.
Stroke incidence among young adults has seen a troubling increase, more than doubling over the past three decades. A recent study conducted by researchers at the University of Cincinnati analyzed data from 2,076 first-ever strokes among adults aged 20 to 54 in the Greater Cincinnati/Northern Kentucky region, covering the years from 1993-1994 to 2020.
During this period, the incidence of strokes rose from approximately 34 to 62 strokes per 100,000 people per year. This increase was primarily driven by ischemic strokes, which occur when a blood vessel supplying blood to the brain becomes blocked.
The study also highlighted a significant rise in risk factors among younger adults who experienced strokes. There was an increase in hypertension, diabetes, atrial fibrillation (an irregular heartbeat), and substance use. David J. Robinson, M.D., an assistant professor of clinical neurology and rehabilitation medicine at the University of Cincinnati College of Medicine, emphasized the serious implications of these findings. “Young people who develop disability from a stroke may no longer be able to work or provide for their families,” he stated.
Robinson noted that while the exact reasons for the rising incidence of strokes among younger adults remain unclear, further research is necessary to understand and potentially reverse this trend. The study also documented a sharp increase in substance use, which rose from 4.6% to 40.2% during the study period, with marijuana being the primary substance noted.
“It’s hard to say whether this is responsible for any of the rise in stroke; there is a relationship between marijuana use and stroke, but most of the evidence is with heavier use,” Robinson explained. He added that the relationship between marijuana use and cardiovascular disease warrants further investigation to provide appropriate guidance to patients.
In contrast to the rising rates among younger adults, stroke rates among older adults have declined, falling from about 619 to 453 strokes per 100,000 people per year. Additionally, short-term survival rates after a stroke have improved. The percentage of younger adults who died within 30 days of a stroke decreased from 11.7% to 9.4%, particularly for strokes related to bleeding, such as intracerebral and subarachnoid hemorrhages.
Robinson noted, “Our study might provide evidence that we have gotten better at treating people who have hemorrhagic strokes and helping them survive, which is encouraging. Still, prevention is the most important thing to focus on, because just surviving a stroke doesn’t mean you aren’t left without disability.”
The findings of this study were published in the journal Neurology on September 23. Dr. Jason A. Gluck, vice chair of the Heart & Vascular Institute and system chief of cardiology at AtlantiCare in New Jersey, commented on the study’s implications. Although strokes remain relatively uncommon in young adults, the upward trend is concerning. “The concerning findings in this particular trial is that stroke rates are moving in the wrong direction for the younger population,” he stated, noting that many risk factors can be identified and treated before a stroke occurs.
Gluck emphasized the importance of awareness, particularly for younger individuals who may not recognize their risk factors. “The same things that happen to 70-year-olds can happen at 40 – if you have high blood pressure, if you have diabetes, if you’re smoking, if there’s obesity, abnormal cholesterol and activity, all those things can lead to stroke,” he warned. “Vascular disease doesn’t suddenly begin when you’re 65; it develops over time.”
One limitation of the study is that it did not include comparable risk factors for individuals without strokes, making it difficult to determine the exact causes of the rising incidence. Robinson pointed out that changes in medical documentation and diagnostic methods over the nearly three decades could have influenced the findings. For instance, increased use of MRI technology may have improved stroke detection, while the rise in substance use could reflect better documentation or disclosure.
Robinson reiterated that while strokes are still relatively uncommon among younger individuals, they can be devastating. He highlighted hypertension as the most closely associated risk factor for stroke. “Younger people may not have a lot of opportunities to get their blood pressure and other risk factors screened, and we need to come up with solutions that can meet them where they are,” he said.
To promote cardiovascular health, Robinson recommended following the American Heart Association’s “Life’s Essential 8,” which includes guidelines for blood pressure control, healthy eating, increased physical activity, quitting tobacco products, getting adequate sleep, managing weight, and controlling cholesterol and blood sugar levels.
Gluck also advised using the “BE FAST” guide to identify potential stroke symptoms. He cautioned, “If you’re having these symptoms or your loved one is having these symptoms, don’t drive yourself to the hospital. Call 911. Be fast.”
As the study highlights, increased awareness and proactive management of risk factors are crucial in addressing the rising incidence of strokes among young adults, a trend that warrants urgent attention and further research.
According to Fox News Digital, the study underscores the need for improved prevention strategies and greater awareness of stroke risk factors among younger populations.
