On his 27th birthday, Frankie Muniz is counting his blessings.

The reason? The former "Malcolm in the Middle" star, who turned 27 on Wednesday, Dec. 5, suffered a mini-stroke last week, as TMZ reported Tuesday.

"I couldn't say words. I thought I was saying them! My fiancee was looking at me like I was speaking a foreign language," Muniz explained on "Good Morning America" on Wednesday.

Concerned about his behavior (a source told TMZ the actor had difficulty comprehending others' speech, as well as speaking on his own), Muniz's friends took him to the ER.

During his "GMA" interview, the actor also revealed he knew something was wrong when he lost vision in one eye while riding his motorcycle. (Muniz claimed he doesn't do drugs, drink or smoke cigarettes.)

"I can't get a deep breath in," the still-stunned Muniz confessed. "I'm still trying to make sense of it, but I'm happy I'm alive."

According to a report by "ABC News," between 10 and 15 percent of stroke sufferers are under age 45.
