Malcolm in the Middle star Frankie Muniz is recovering from a mini-stroke, and he's just turned 27 today.
Muniz told Good Morning America he knew something was very wrong.
Muniz says he was on his motorcycle in Phoenix when his vision went blurry. He says until the mini-stroke, he thought he was living a very healthy lifestyle.
"I have literally to this day, never had a sip of alcohol. I've never had any drugs and never smoked a cigarette," said Muniz.
INSIDE EDITION spoke to Dr. Steven Reisman, director of the New York Cardiac Diagnostic Center, who said, "A mini-stroke is temporary. The key word is temporary. It comes and it goes, usually within several hours. It's really a warning sign. A full stroke is usually more premanent damage that can last, that can be severe, or mild or moderate, and it doesn't go away quickly."
While rare, strokes can occur to people of all ages, even young children.
Seven-year-old Hope Espinoza was a beauty queen on TLC's Toddlers and Tiaras in 2010, and then, out of the blue, she had a stroke. Hope's left leg and arm were paralyzed but she's learning to use them again.
As for Muniz, he's being told to take it easy for the time being but is expected to make a full recovery.
"I am still trying to make sense of it, but I am happy that I'm alive," said Muniz.
