The difference between ADHD and autism

Trouble paying attention to people. Being constantly on the move. Invading personal space, not reading social cues well, and having meltdowns. These can all be signs of both ADHD and autism. And the two conditions can occur together.

So what’s the difference between ADHD and autism, also known as autism spectrum disorder (ASD)? This table breaks down some of the key differences between them.




What is it?

A neurodevelopmental condition that makes it hard for kids to concentrate, pay attention, sit still, and curb impulsivity.

A range of causing challenges with social skills, communication, and thinking. Repetitive behaviors are also part of autism spectrum disorder (ASD).

Signs you may notice, depending on your child

Seems forgetful, easily distracted, or daydreamy

Appears not to listen and has trouble following directions

Is prone to tantrums and meltdowns due to frustration or lack of impulse control

Struggles with organization and completing tasks

Has trouble staying on task unless an activity is very enjoyable

Struggles with social skills

Struggles to sit still during quiet activities, such as mealtimes or during independent work time at school

Has trouble taking turns and being patient

Is constantly “on the go” or moving; fidgets and needs to pick up and fiddle with everything

Interrupts people, blurts things out inappropriately, and may struggle with nonverbal cues

Acts without thinking and may not understand the consequences of actions

May overreact to sensory input, like the way things sound, smell, taste, look, or feel

Plays roughly and takes physical risks

Avoids eye contact and/or physical contact

Has delayed speech (or no speech) or repeats phrases over and over

Is prone to meltdowns due to sensory processing issues, anxiety, frustration, or communication difficulties

Gets upset by changes in routine

Struggles with social skills

Uses excessive body movements to self-soothe (e.g., rocking, flapping hands)

Has obsessive interests and experiences perseveration

Is constantly “on the go” or moving; fidgets and needs to pick up and fiddle with everything

Is very advanced verbally, but struggles with nonverbal cues

Has trouble showing understanding of other people’s feelings and their own

Reacts strongly to the way things sound, smell, taste, look, or feel (sensory processing issues)

Has trouble with safety and danger awareness

Possible emotional and social impact

Trouble following social rules can make it hard to make and keep friends. Frequent negative feedback for acting out or not paying attention can impact self-esteem and motivation, making a kids feel they’re “bad” or “no good.” (Read more about ADHD and emotions.)

The main struggles of ASD involve social understanding, communication and repetitive routines or behaviors. Many kids with ASD — even those without significant cognitive challenges — have trouble making friends, relating to other people, and making sense of social cues.

Pediatricians, neurologists, developmental-behavioral pediatricians, nurse practitioners, child psychiatrists: Diagnose ADHD and prescribe medication. Can also look for other issues like anxiety.

Clinical child psychologists: Provide behavior therapy to teach kids to manage their actions and interactions. Provide cognitive behavioral therapy to help with emotional issues related to their ADHD. Diagnose ADHD and mental health issues that may co-occur, like anxiety. May also evaluate for learning differences.

Pediatric neuropsychologists: Diagnose ADHD and common mental health issues that may co-occur. May also evaluate for learning differences.

Educational therapists, organizational coaches: Work on organization and time management skills.

Pediatricians, neurologists, developmental-behavioral pediatricians, child psychiatrists, psychologists: Identify possible signs of autism and may diagnose. May also refer for early intervention services.

Speech therapists: Work on speech-language and pragmatic language skills to help kids communicate and understand others more easily.

What the school may provide

A child might be eligible for an IEP under the category of “other health impairment.” Accommodations can also be provided under a 504 plan. Examples might include:

A seat close to the teacher and away from distractions

A quieter work space to get work completed without distraction

A signal, nonverbal cue, or picture card to get the child’s attention

Help breaking long assignments into smaller chunks

Written or picture schedules for daily activities

Movement breaks

A child might be eligible for an IEP under the category of “autism.” Special education may be provided along with accommodations. They are specific to each child, but examples can include:

A seat closer to the teacher and to classroom materials

A work space with limited auditory and visual distractions

Visual prompts and color-coding to highlight and teach new information

A sensory diet and activities throughout the day

Social stories to present new ideas and situations

Being provided with choices to ease anxiety

Being provided with “wait time”

What you can do at home

Set clear rules and expectations for your child.

Create daily routines to provide structure.

Break directions and tasks into smaller chunks.

Teach your child to use visual prompts like checklists, picture schedules, and sticky notes to help focus, stay organized, and get things done.

Allow for flexibility during homework time for brain and movement breaks.

Create an organized homework and study area.

Give advance warning about changes in the schedule and explain what to expect in new situations.

Set clear expectations and create daily routines.

Break directions into smaller chunks and use picture prompts.

Have a plan to manage meltdowns.

Use a visual timer or signal to make it easier to transition from one thing to the next.

Role-play and teach scripts for social situations.

These are some common examples. But because ASD looks so different in each child, the support provided at home varies a lot. Parents will often work with a psychologist or other clinicians to create a support plan.
