Former Malcolm in the Middle star Frankie Muniz has suffered his second mini-stroke in under a year.
The 27-year-old actor revealed on Twitter he was “miserable” after experiencing another lapse.
“Almost a year to the day, I experienced another mini stroke. Hopefully that will be the last. Miserable,” he wrote on 25 November.
Muniz suffered his first mini stroke in December last year when he was taken ill in Arizona after losing vision in one eye while riding his motorbike.
He wrote at the time: “Have to start taking care of my body! Getting old!”
A mini-stroke, or transient ischaemic attack (TIA), is caused by a temporary disruption in the blood supply to part of the brain.
Symptoms can be similar to a stroke, for example problems with speech and vision, but only last for a few minutes and are usually gone within 24 hours.
Muniz put his acting career on hold seven years ago to race cars for a living. He also plays the drums in an American band called Kingsfoil.
The actor’s career since 2006 has not matched the success of Malcolm in the Middle, a sit-com that ran for 150 episodes in which Muniz played title character Malcolm, a genius middle child who finds it hard to fit in.
Earlier this year, Muniz openly criticised the launch of Obamacare, which saw thousands of Americans unable to access its website healthcare.gov.
“This Obamacare launch is an embarrassment to the American people. How many more promises have to be broken?” he tweeted.
