How common is binge eating disorder actually among adults with ADHD compared to the general population?

Research suggests a meaningfully higher rate. 6% in the general population, and other studies looking at ADHD symptoms specifically within eating disorder populations have found roughly a quarter to a third screening positive for possible ADHD. It's a well-documented enough overlap that clinicians treating either condition are increasingly encouraged to screen for the other.
