ADHD symptoms go beyond trouble with focus, impulsivity, and hyperactivity. Dr. Russell Barkley, an authority on ADHD, developed the model of ADHD being like an iceberg. Some symptoms are easy to recognize. But others are “below the surface.” People may not even notice them — or realize that they’re part of ADHD.

People can have any of these symptoms to varying degrees, and not everyone has them. Download the ADHD iceberg infographic to learn more. 

Plus, listen to this episode of the ADHD Aha! podcast to hear from a woman who decided to be evaluated for ADHD after seeing the ADHD iceberg infographic — and relating to almost every below-the-surface ADHD symptom.
