The Emmy-nominated host of Deal or No Deal is very open about having ADHD and OCD. In addition to writing about his condition (with a lot of humor) in his 2009 memoir Here's the Deal: Don't Touch Me, Mandel has worked vigorously to raise awareness about these illnesses. As part of the "Adult ADHD Is Real" campaign, the Canadian cutup admitted, "When I was in high school, my impulsivity led me to all kinds of acts and pranks. I had trouble sitting still and could hardly focus or pay attention in class. It wasn't until I was an adult that I was diagnosed with ADHD… [but] I didn't let ADHD prevent me from achieving my goals and neither should anyone else."
