8. Howie Mandel
Canadian comedian and TV host Howie Mandel has long been open about his lifelong battle with a variety of mental health issues, including ADHD and obsessive compulsive disorder.
In an op-ed for ADDitude Magazine, the presenter wrote: “Back in the 1960s when I was growing up, my symptoms didn’t have a name and you didn’t go to the doctor to find out. So, in my case, they were called ‘Howie Mandel'”.
Nowadays, the America’s Got Talent host takes medication and goes to regular therapy sessions to help him cope with his ADHD diagnosis and other issues.
