Are ADHD and Autism Similar?

You may have heard that up to 50-70% of people or 38% of children with autism spectrum disorder also have ADHD. It is also believed that the symptoms of autism and ADHD overlap.

While it’s true that these conditions often co-exist and can present similarly, the reasons behind the symptoms can differ depending on whether an individual has ADHD, autism, or both (often referred to as AuDHD).
