Autism vs. ADHD: What’s the difference?

As parents, we all want to understand our kids better—especially when they seem to experience the world a little differently. Two terms you might hear a lot are autism and ADHD. They can look similar in some ways, but they’re not the same thing. Knowing the differences can help us support our children in the ways they need most.

What is Autism?

Autism, or Autism Spectrum Disorder (ASD), is all about how a child communicates, interacts, and processes the world around them. The word “spectrum” is key—every child with autism is unique, with their own strengths and challenges.

Some common signs you might notice:
  • Finding it hard to connect with other kids or understand social cues.
  • Preferring routines and getting upset if those routines change.
  • Showing a deep interest in specific topics or hobbies.
  • Being sensitive (or less sensitive) to sounds, textures, lights, or movement.
  • Learning better with visuals, structure, or hands-on support.

Every child on the spectrum experiences autism differently—there’s no one-size-fits-all.

What is ADHD?

ADHD (Attention Deficit Hyperactivity Disorder) is more about focus, energy, and impulse control. Kids with ADHD may struggle to sit still or stay on task, but they also tend to be creative, energetic, and full of fresh ideas.

Some common signs you might notice:
  • Getting easily distracted or forgetting things often.
  • Fidgeting, bouncing, or always seeming “on the move.”
  • Blurting things out or having trouble waiting their turn.
  • Struggling to stay organized or finish tasks.
  • Doing best when they can move, explore, and learn in active ways.

How They’re Different

Because both autism and ADHD can involve focus and behavior differences, it’s easy to mix them up. But here’s a quick way to think about it:

Children with autism often find social rules confusing and may prefer routines, predictability, and sometimes alone time. They might have very deep focus on specific interests and unique communication patterns. On the other hand, children with ADHD usually want to connect with others but may interrupt, seem impatient, or get easily distracted. They often bounce between tasks, act on impulse, and thrive on novelty and movement.

It’s also possible for a child to have both autism and ADHD, which can make things more complex—that’s why getting professional support and guidance is so important.
