ADHD Decoded

Finally—a way to understand ADHD diagnostic criteria without needing a psychology degree.

This visual guide breaks down the DSM-5 definitions for ADHD into clear, visual clusters, showing the real-life meaning behind “inattention,” “hyperactivity,” and “impulsivity.” It also explains the three ADHD subtypes (Inattentive, Hyperactive-Impulsive, and Combined) and how symptoms often present differently in adults versus children.
