As the exhausted mother of a child with ADHD who sometimes feels desperate for one moment of elusive silence, I often wonder: can he outgrow this?...CHADD, a charity that offers support, information, and advocacy to people with ADHD, gave me the answer to the question I've asked myself so many times, even if it wasn't the answer I wanted to hear: symptoms of ADHD persist in 50 to 86 percent of adults who had ADHD as children. It just looks different later in life1.
