Frankie Muniz was 15 when he was nominated for an Emmy for Outstanding Lead Actor in a Comedy Series.
He was the star of Malcolm in the Middle, the critically acclaimed family sitcom that ran for seven seasons, with a debut audience of 23 million. Actors such as Emma Stone, Hayden Panettiere, Susan Sarandon, and Heidi Klum guest starred on the show, as well as celebrities like Magic Johnson. For a young actor, it was the opportunity of a lifetime.
But Muniz, now 32, doesn’t remember a moment of it.
He couldn’t tell you anything about attending the Emmys, or what it’s like to have Breaking Bad’s Bryan Cranston play your on-screen father.
In October last year, while Muniz was appearing on Dancing with the Stars, the show ran an episode with the theme ‘Most Memorable Year’. Being asked to recall events from his childhood and adolescence, he made the matter-of-fact statement that he has no memory of being on Malcolm 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 on Dancing 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.
