Frankie Muniz

Starring in films such asBig Fat Liar,Agent Cody BanksandMalcolm in the Middle, every teenage girl adored Frankie Muniz in the '00s.

After starring in those roles, Muniz put his acting career on hold to focus on car racing and competed in the Atlantic Championship Series, where he came eleventh.

Then years later, he competed in the USDancing with the Starsin 2017.

While Muniz was appearing on the show, he was asked to recall events from his childhood and adolescence. He then made the matter-of-fact statement that he has no memory of being onMalcolm in the Middle.

"I'm not actually sure how my memory loss started," he said. "I have had nine concussions and I've had a fair amount of mini-strokes."

"I've never been to the doctor and been like, you know, 'Why don't I have a memory?' To be honest, I've never really talked about it.

"It makes me a little sad. Things pop back into my mind that I should have remembered."

Speaking to Entertainment Weekly after his appearance onDancing with the Stars, Muniz said he had his first 'mini-stroke' (otherwise known as a transient ischemic attack - involving a temporary blockage in the brain) in 2012. He was riding a motorbike and suddenly lost his peripheral vision, and when he returned home, he couldn't recognise his mum or girlfriend. When he went to the hospital he was given no definitive answers.

"I’m 31, I’ve never sipped alcohol, I’ve never touched a drug or taken a drag of a cigarette," he said. "The only thing I’ve felt was stress. I’m a high-strung person. I just like to always be moving. I’m not good at relaxing."

Despite not understanding his condition, Muniz said, "It’s not something I think about. I don’t go, ‘Oh man I’m really scared, I really need to know.' I just move forward."

Since then, Muniz has hostedDancing with the Stars Juniorsand married his long-time girlfriend, Paige Price.
