The death of Luke Perry, after the actor suffered what his publicist said was a massive stroke, is evidence that the disease can affect people of any age, the American Heart Association said.
Perry, who starred in "Beverly Hills 90210" and "Riverdale," died Monday. He was 52.
"Although stroke often affects older individuals, it is not only a disease of the elderly," said Mitchell S. V. Elkind, chair of the American Stroke Association Advisory Committee. "There is evidence that stroke rates among young people are increasing in the United States and this requires additional research."

A 2017 report by the American Academy of Neurology found that 15% of all ischemic strokes happen to young adults and adolescents. But a lack of research, awareness and frequency makes diagnosing the symptoms early on a challenge.    
Ischemic strokes account for 87% of all stroke cases. They occur when a blood vessel becomes blocked by fatty deposits and blood has trouble passing through to the brain.
Other types of strokes include thrombotic ischemic stroke -- triggered by a blocked vessel -- and a hemorrhagic stroke, caused by weakened blood vessels that rupture and bleed into the brain.
