Frankie Muniz is recovering after having a "mini stroke." On Tuesday, the "Malcolm in the Middle Star" tweeted, "I was in the hospital last Friday. I suffered a 'Mini Stroke', which was not fun at all."
The 26-year-old added, "Have to start taking care of my body! Getting old!"
He spoke to "Good Morning America" about the surreal experience. "I couldn't say words," he said. "I thought I was saying them! And, my fiance was looking at me like I was speaking a foreign language."
Mini strokes can result from blood clots or from narrowed or injured vessels that supply blood to the brain. The resulting stroke-like symptoms typically resolve after an hour or two.
While they're not fatal, a 2011 study by Australian researchers found they can shorten your life. They also boost the risk of a full blown stroke.
Muniz put his acting career on hold shortly after "Malcolm in the Middle" ended in 2006 to focus on race car driving and music. He had a cameo in an episode of ABC's "Don't Trust the B-- in Apartment 23? earlier this year.
