Michael Phelps-ADHD
Michael Phelps is an American swimmer, who has won a record-breaking 19 Olympic medals during his swimming career. He also lives with attention-deficit-hyperactivity-disorder. “For Phelps, a gangly, hyperactive child who was diagnosed with the condition aged nine, the swimming pool was a sanctuary, a place to burn off excess energy,” writer Patrick Barkham says. “The concept of role models can seem an overused cliche but the Olympians with ADHD may really inspire a generation of athletes who once would have been written off.”

Dan Reynolds-clinical depression
Dan Reynolds may be living the dream as a member of the chart-topping band Imagine Dragons but despite commercial success and a rewarding musical career, Reynolds described himself as “depressed as hell.” Since 2012, Reynolds has been honest about his battle with depression. “That’s a scary thing when you get everything that you could have wanted but yet you still feel an emptiness because, at that point, you think, ‘Oh man, if this doesn’t fill it, then I don’t know where to look anymore.” His new role as a husband and father has motivated him to make positive changes. “That made me feel like I needed to reevaluate my life and find a deeper appreciation for it."

Leonardo DiCaprio-obsessive-compulsive disorder
The Oscar-winning star admitted he feels compelled to walk through doorways numerous times and step on sidewalk stains left by used chewing gum.

You don’t need to do that.’”
