The ADHD-Autism Overlap: Why So Many People Have Both
Source: ADDitude Magazine
Visit sourceADDitude Magazine's comprehensive guide to the ADHD-Autism connection covers the clinical evidence, the shared neurobiology, and the practical implications of having both conditions.
Key takeaways: co-occurrence rates are far higher than chance would predict (50-70% of autistic individuals also meet ADHD criteria), the DSM-5 only permitted dual diagnosis in 2013, and many adults were diagnosed with one condition while the other went unrecognized for years or decades.
The guide also addresses the diagnostic challenges — how autistic focus can mask ADHD inattention, and how ADHD sociability can mask autistic social differences.
