Strokes are most common in old age, but new research suggests that particular lifestyle choices are putting young people increasingly at risk for stroke. In a study, researchers found the rate of strokes among adults younger than 55 nearly doubled between 1993 and 2005. Among African Americans, it climbed from 83 to 128 per 100,000.
The researchers said they could only speculate on possible explanations. One might be that doctors are detecting strokes in young people more often – both as a result of better brain-imaging technology and of being more vigilant for stroke in the young.
“But I really don’t think that’s the major reason,” said lead researcher Dr. Brett M. Kissela, of the University of Cincinnati College of Medicine. “We’re definitely seeing a higher incidence of risk factors for stroke now,” he said in an interview.
Those risk factors include obesity, diabetes and high blood pressure.
“And if you’re developing them at the age of 20,” Kissela said, “then you may have a stroke at a younger age, too.”
A researcher not involved in the study agreed that better diagnosis and a real increase in young people’s risk of stroke are both probably at work. “Now MRI allows us to detect smaller strokes,” said Dr. Mitchell S.V. Elkind, of Columbia University in New York, who co-wrote an editorial published with the study. “Strokes come in all shapes and sizes,” Elkind said.
That includes subtle symptoms like mild degrees of blurry vision, weakness or numbness. In the past, doctors might not have thought “stroke” when a relatively young person had symptoms like that. And MRI scans, which can detect subtle brain damage from stroke, were not used often back in the 1990s.
