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.
The cause and type of Perry's stroke has not been revealed. But Elkind said it's important to know risk factors and symptoms.
The risk factors
Stroke is the second leading cause of death worldwide -- and high blood pressure is the leading cause of stroke, according to the American Stroke Association.
Smoking, diabetes, high blood pressure, high blood cholesterol, obesity and other cardiovascular diseases put people at greater risk for stroke, the heart association said. Avoiding diets with high calories, lots of saturated fat, trans fat and sodium can reduce the risk, as can getting 150 minutes of activity each week, the association said.
The symptoms
The American Heart Association recommends using the acronym F.A.S.T. to remember how to catch the warning signs of a stroke:
Face is drooping.
Arms are weak.
Speech difficulty.
Time to call 911.
