Autism and ADHD Together: Signs, Overlap and What Helps
Published November 2, 2026 · Last updated November 2, 2026
If your child has an autism diagnosis but still cannot sit still, loses focus or acts on impulse, or if they have an ADHD diagnosis but also struggle socially and with change, you may be seeing both. This guide explains how often they occur together, how signs overlap, and what to try at home and school.
Yes, a child can have autism and ADHD together. Since the DSM-5 in 2013, both can be diagnosed, and research suggests a large share of autistic children also have ADHD, with estimates varying widely. Signs overlap, so one can hide the other. Ask for an evaluation that looks at both, and plan structure, movement breaks and sensory support.
- Together?: Yes. Since 2013, DSM-5 allows both diagnoses.
- How common: Estimates vary widely, from about 3 in 10 to about half in different studies.
- Why missed: Signs overlap, so one diagnosis can hide the other.
- What helps: Structure, visual supports, movement breaks, sensory support and a full evaluation.
Can a Child Have Autism and ADHD Together?
Yes. Before the DSM-5 was released in 2013, the manual did not allow a diagnosis of both autism and ADHD in the same person. Since then, clinicians can diagnose both, and research has shown that many autistic children also have ADHD. Estimates vary widely. A 2022 study using data from the US National Survey of Children's Health reported that over half of autistic females (57%) and nearly half of autistic males (49%) also had an ADHD diagnosis. Older research following children from toddlerhood found that about 29% of children with autism also had clinically significant ADHD symptoms. Rates differ because of how and when children are studied.
Why It Is Easy to Miss
The signs overlap, so one diagnosis can hide the other. A child who cannot sit still and talks over others might be called "just ADHD" while their social differences, sensory sensitivities and need for routine go unexplored. A child with strong interests who struggles with peers might be diagnosed with autism, while attention and impulsivity go unaddressed. Children with both conditions may also look different from children with only one.
What Both Can Look Like at Home, and What to Try
| What you see | What may be going on | What to try | Why it helps |
|---|---|---|---|
| Cannot sit through homework, yet gets upset if you change the routine | Attention and impulse control are hard, and so is change | Fixed homework time, a visual timer, 10-minute work blocks and a movement break | Predictable structure and short bursts suit both |
| Interrupts and grabs toys, then does not understand why others are upset | Impulsivity plus difficulty reading social cues | Practice "wait, ask, then take" with a puppet. Use a stop signal | Gives a rule and a visible cue |
| Covers ears at noise and also cannot focus in class | Sensory overload plus distractibility | Seat away from noise and doors. Allow headphones | Cuts the distractions that make focus harder |
| Loses things, forgets steps in routines | Executive function (planning, memory, organizing) is a shared difficulty | A picture checklist on the door, a bag with a set place, two-step instructions | External reminders replace memory |
| Big emotions and fast meltdowns | Both can cause trouble with emotional control | Calm-down corner, feelings chart, practice breathing with a pinwheel or bubbles | Gives a plan for big feelings and something to do with the body |
| Seems "on the go" all day, tires out and melts down | Hyperactivity plus effort of coping | Scheduled physical activity before homework and a quiet recovery period after school | Uses energy and then allows rest |
This order works because it follows the child's energy: rest first, then movement, then short work with a visible end, then a break and a reward your child looks forward to. Adjust times to your child, and use the same order every day so the routine itself becomes the cue.
Tools and Activities That Help, and Why
Start with the ones that fit your child today. Pick two or three, try them for a week, and keep notes on what works.
| Tool or activity | Why it helps | How to use it |
|---|---|---|
| Visual timer | Makes time visible, which is hard for both conditions | Set it for short blocks of work and break time |
| Picture checklists | Replace memory for multi-step routines | Mount on the door for morning and bedtime |
| Movement breaks (jumping, wall push-ups, animal walks) | Burn energy and reset focus | Schedule them before sitting tasks |
| Fidget tools | Give hands a job so the mind can listen | Choose quiet ones for school |
| Noise-reducing headphones | Cut distractions | Use for homework or crowded places |
| Reward chart with small, quick rewards | Gives fast feedback, which suits ADHD | Reward specific behavior within minutes, not at the end of the week |
| A calm-down corner | A place to recover when overloaded | Stock with preferred items. No demands inside |
| Body doubling (sit nearby while your child works) | Having someone nearby helps with focus and starting | Do a quiet task of your own next to them |
| "Beat the clock" game for chores | Turns a task into a game with fast feedback | Use 5 minutes and let your child set the timer |
| Two-step instructions with a picture cue | Fewer steps reduce the load on memory | Say one step, show a picture, then give the next |
| Wobble cushion or standing desk | Allows movement while working | Try for short blocks and check with the teacher or an OT |
| Launch pad by the door (bag, shoes, keys) | A fixed place for things removes searching | Use colored boxes and keep it the same every day |
| Brain break games (freeze dance, animal walks) | Short bursts of movement reset attention | Two minutes between work blocks |
Getting an Evaluation
Ask for an evaluation that looks at both autism and ADHD, because assessing only one may miss the other. A developmental pediatrician, child psychologist or child psychiatrist with experience in both is ideal. Bring school reports, examples from home and your list of concerns. See our guide to autism symptoms and signs and, if you are in the US, the evaluation process.
Treatment and Support
A support plan should cover both. Options may include behavioral and developmental therapies, parent coaching, school accommodations and, for some children, medication for ADHD symptoms. Medication decisions belong with your child's doctor, who can weigh benefits and side effects, and what helps one child may not help another. Review the plan regularly.
Watch for Anxiety and Low Mood
The 2022 study found high rates of anxiety and depression among autistic adolescents who also had ADHD, about 72% of autistic females and 69% of autistic males with anxiety, and about 38% to 39% with depression. The authors recommend a high index of suspicion for anxiety and depression in every child with autism or ADHD, and note that early identification and treatment may improve outcomes. Talk to your doctor if you see persistent worry, sadness, withdrawal or sleep changes.
At School
Children with both conditions often need structure, clear short instructions, movement breaks, a quiet space and a trusted adult. In the US, these can be part of an IEP or 504 plan. See IEP vs 504 plan.
Strengths
Children with both conditions can be creative, energetic, curious and deeply focused on what they love. Use that. A project that combines movement and an interest, like building a model or running a "train timetable," can engage both.
Frequently Asked Questions
Can a child have both autism and ADHD?
Yes. Since the DSM-5 in 2013, clinicians can diagnose both. Research shows many autistic children also have ADHD, and estimates vary widely depending on the study.
How common is it to have both?
Studies give different numbers. One 2022 US survey analysis found over half of autistic females (57%) and nearly half of autistic males (49%) also had an ADHD diagnosis. Older research following children from toddlerhood found about 29%.
What is the difference between autism and ADHD?
Autism involves differences in social communication, repetitive behaviors, narrow interests and need for routine. ADHD involves inattention, hyperactivity and impulsivity. They can overlap and occur together.
Can ADHD medication help a child with autism?
It can help some children with ADHD symptoms. Decisions about medication should be made with your child's doctor, who can weigh benefits and side effects for your child.
How do I know if my autistic child also has ADHD?
Look for persistent inattention, restlessness and impulsivity beyond what is expected for age, across settings. Ask your clinician for an evaluation that looks at both.
What helps a child with both autism and ADHD at school?
Clear structure, short instructions, visual schedules, movement breaks, a quiet space and a trusted adult. Ask the school about an IEP or 504 plan.
Does having both make autism worse?
Children with both can face more challenges, including with daily skills and mental health, according to research, which is why a full evaluation and a support plan covering both are important.
Should I get a second evaluation?
If your child has one diagnosis and you still see signs of the other, or treatment is only partly helping, ask for an evaluation by a clinician experienced in both conditions.
