Study finds rates of ADHD remain high into adulthood among patients with autism

In a large study of more than 3.5 million adults, researchers from Children’s Hospital of Philadelphia (CHOP), Drexel University and George Washington University (GWU) found that attention deficit hyperactivity disorder (ADHD) was highly elevated among adults diagnosed with autism spectrum disorder. Additionally, co-occurring ADHD was associated with worse health outcomes, though patients who received medications for ADHD had better outcomes.
