What percentage of children who are diagnosed with ADHD as a child eventually outgrow it as an adult?

Several studies have looked at how many children diagnosed with attention-deficit/hyperactivity disorder (ADHD) continue to meet the diagnostic criteria as adults. However, the exact percentage who “outgrow” ADHD varies across different studies. Here’s a summary of some of the research findings:

1) A long-term follow-up study published in 2016 found that around 30% of children with ADHD appeared to no longer meet the criteria for ADHD as adults.

2) Another study published in 2005 estimated that about 65% of children with ADHD continued to have symptoms that met the diagnostic criteria in adulthood.

3) A meta-analysis published in 2006 that combined data from multiple studies found that around 15% of children with ADHD no longer had the disorder by age 25.

4) Some research suggests that while core ADHD symptoms like inattention, hyperactivity, and impulsivity may persist, they tend to decrease with age, especially the hyperactive symptoms.

So in summary, estimates from different studies vary, but it appears that somewhere between 15-35% of children diagnosed with ADHD may outgrow the full disorder by adulthood, while the majority continue to have some level of symptoms and impairment. However, many experience a reduction in symptom severity over time.
