Frankie Muniz, former star of the sitcom "Malcolm in the Middle", tweeted to his fans that he had suffered a mini-stroke, nearly one year after the first one.

"Almost a year to the day, I experienced another mini stroke," he shared on Twitter. "Hopefully it will be the last. Miserable."

In an interview with "Good Morning America" after the first incident, Muniz said the trouble started when he lost vision in one eye while riding his motorcycle. "I couldn't say words. I thought I was saying them! My fiance was looking at me like I was speaking a foreign language," he said.

A mini-stroke is when the blood flow to the brain is stopped for a brief moment but does not cause brain tissue death as opposed to a regular stroke.
