Frankie Muniz, who starred in the US sitcom Malcolm in the Middle, has told Newsbeat he thinks stress caused him to have a mini stroke.
The 27-year-old was taken into hospital last December after he started having trouble speaking.
At the time, his band Kingsfoil had just come off tour and were releasing an album on their own label.
Muniz talks to Newsbeat's Chris Smith about what causes him to get stressed.
