Most researchers agree that ADHD lasts a lifetime. “Numerous longitudinal studies now support the conclusion that ADHD is a relatively chronic disorder affecting many domains of major life activities from childhood through adolescence and into adulthood” (Barkley, 2006). The impact of ADHD on adults will likely become as widely studied as its impact on children.
Some encouraging news is that puberty or maturation changes types of ADHD behaviors for some boys. According to Silver (1999), “About 40–50 percent of children with ADHD will improve or no longer have ADHD after puberty”.
