Share of Cost, Study estimates ADHD symptom persistence into adulthood

Sixty percent of children with ADHD in a recent study demonstrated persistence of symptoms into their mid-20’s, and 41 percent had both symptoms and impairment as young adults.

Investigators noted that rates of ADHD persistence into adulthood have varied greatly in earlier studies, depending on how information is collected and analyzed. In a 16-year follow-up of the Multimodal Treatment Study of Children with ADHD (the “MTA”), they found that a combination of parent and self-reports plus a symptom threshold that is adjusted for adulthood (rather than based on traditional childhood definitions of ADHD) may be optimal.
