ADHD vs ASD: Understanding the Key Differences
Some parents may confuse Attention-Deficit/Hyperactivity Disorder (ADHD) with Autism Spectrum Disorder (ASD) — and that’s understandable.
The two conditions can share overlapping traits, such as difficulties with focus, social interaction, or self-regulation. However, there are important differences in their causes, symptoms, and support needs.
The comparison below outlines the main distinctions to help you understand how ADHD and ASD present differently in children.
-
ADHD: A neurodevelopmental condition that affects attention, self-control, and impulse regulation.
ASD: A neurodevelopmental condition that affects social communication, sensory processing, and behavioural flexibility.
-
ADHD: Difficulty focusing, forgetfulness, impulsivity, constant movement, emotional reactivity.
ASD: Challenges with social cues, repetitive behaviours, sensory sensitivity, preference for routines.
-
ADHD: May have difficulty maintaining friendships; can appear inattentive or impulsive.
ASD: May seem withdrawn or unaware of social norms; benefits from structure and explicit teaching.

Can ADHD and ASD Occur Together?
Yes. Some children have both ADHD and ASD, which means they may struggle with attention and impulse control while also finding social communication or sensory input challenging.
In these cases, early assessment helps clarify overlapping symptoms and guide the right mix of therapeutic supports.
