In an interview with the U.K.'s Times Radio, the U2 drummer shared that he's recently been diagnosed with dyscalculia, a learning disability that results in difficulty learning or comprehending arithmetic, sometimes referred to as "math dyslexia."
This is the first time Mullen has talked about his learning disability, and he made the revelation while promoting the new documentary Left Behind, which he co-produced. He also wrote two songs for the film, "Between The Lines" featuring GAYLE and "One of Us" featuring Welsh singer Donna Lewis, which are out now.
Left Behind is set to open Jan. 17 for a weeklong engagement at New York City's QUAD Cinema. It will then expand to select theaters nationwide.
