Zayn Malik Was 'Wild' Before Being Diagnosed With ADHD

Zayn Malik has revealed lots about his past in his new autobiography Zayn, including his battle with anxiety and an eating disorder.

The 23-year-old entertainer just revealed that he also struggles with ADHD in a new excerpt from the book.

“[Growing up] I was pretty wild. I could never focus, couldn’t get a handle on where my brain wanted to go. I was constantly getting in trouble,” he wrote.

Zayn added, “Once, when I was at Tong High School, I was collared for a BB gun in class. It wasn’t loaded or anything, but me waving it around didn’t go down too well. I was later diagnosed by doctors as having super-hyperactivity�or ADHD (Attention Deficit Hyperactivity Disorder) as they like to label it.”
