Yes, you can have ADHD and autism together; only a trained clinician can confirm both diagnoses.
Hearing terms like ADHD and autism can stir relief, worry, or a mix of both. If you see yourself in traits from each, you might ask the exact question in this title and wonder what it means for your life.
This article walks through what ADHD and autism are, how they can overlap, how often they appear together, and what next steps might look like if you relate to both. It is information to help you feel more prepared, not a replacement for medical care.
Can I Have ADHD And Autism? What That Question Really Means
When someone asks, “can i have adhd and autism?”, they are often trying to make sense of long running patterns. You might notice social friction, sensory overload, restlessness, or racing thoughts and wonder if one label fits, or if both fit together.
ADHD and autism sit under the broader group of neurodevelopmental conditions. That means they relate to how the brain develops and processes information from early life. Many people who meet criteria for one also meet criteria for the other. Research reviews suggest that around three to seven out of ten autistic children also meet criteria for ADHD, depending on the study and methods used.
At the same time, another person might ask, “can i have adhd and autism?” and later learn that one diagnosis explains their traits more clearly than the other. Overlap is common, but each person’s pattern is unique.
What ADHD And Autism Look Like On Their Own
To understand overlap, it helps to see how ADHD and autism each tend to show up. These are broad patterns, not checklists. People can sit anywhere on the spectrum of traits, and many live in ways that do not match stereotypes at all.
ADHD In Brief
ADHD often involves a long term pattern of inattention, hyperactivity, and impulsive behaviour. Some people mainly drift off, lose track of tasks, and forget what they planned to do. Others feel driven to move, talk a lot, or switch tasks in a rush. Many sit somewhere between those two pictures.
Autism In Brief
Autism often involves differences in social communication and a strong pull toward certain interests or routines. A person might read between the lines in a different way, miss unwritten rules, or feel worn out by small talk. Sensory input such as noise, light, fabrics, or smells can feel intense or dull compared with people around them.
Common Traits In ADHD And Autism
ADHD and autism are described separately in manuals, yet daily life traits often blend. The table below shows patterns many people notice. These examples are not diagnostic rules, only a simple way to compare.
| Area | ADHD Tends To Include | Autism Tends To Include |
|---|---|---|
| Attention | Shifting focus quickly; hard to stay with low interest tasks | Narrow, intense focus on specific interests; hard to move attention away |
| Activity Level | Restlessness, fidgeting, feeling “driven” to move | Movement that follows set patterns, such as pacing or hand movements |
| Social Interaction | Interrupting, speaking before thinking, losing track of conversations | Differences in reading facial cues, tone, or unspoken rules |
| Communication Style | Talking a lot, jumping between topics, blurting thoughts | Plain, direct language; may miss or skip small talk |
| Sensory Experiences | Seeking stimulation to stay engaged, such as music or movement | Strong reactions to sound, light, textures, or smells |
| Routine And Change | Struggling to keep routines, losing track of plans | Wanting clear routines and feeling unsettled by sudden change |
| Executive Skills | Starting, organising, and finishing tasks can feel like climbing a hill | Planning and flexibility can feel rigid, especially around interests |
| Emotional Reactions | Quick shifts in mood, strong frustration during delays or boredom | Strong reactions to sensory overload or social misunderstandings |
Because these traits can blend in daily life, many people who show traits from both groups now use the informal term “AuDHD”. It is not an official diagnosis in manuals, but it gives some people a quick way to express that they relate to both ADHD and autism at once.
Having Both ADHD And Autism: Is It Possible?
Short answer: yes. Large studies and reviews report that ADHD and autism often appear together. Research that tracks autistic children finds that roughly a third to almost half also meet criteria for ADHD at some point in life. Other surveys that start from ADHD see autism in a smaller but still meaningful share of children and adults.
One national US survey found that around one in eight children with a current ADHD diagnosis also had an autism diagnosis. That group tended to have more complex care needs and more traits from both conditions. Findings like this fit with newer work showing shared genetic factors across ADHD and autism.
Health agencies also list autism among the conditions that often appear alongside ADHD. CDC data on ADHD describe autism spectrum disorder as one of the common co existing conditions seen in children with ADHD. Clinical guidelines, such as the United Kingdom’s NICE guidance on ADHD, also encourage teams to check for more than one diagnosis when traits suggest it.
How Often ADHD And Autism Occur Together
Exact numbers vary a lot from one paper to another. Differences in age groups, definitions, and who takes part in the research all shift the totals. Still, some patterns repeat across studies.
When researchers start with a group of autistic children or adults, they often find ADHD symptoms in around four out of ten, sometimes higher. When they start with people diagnosed with ADHD, rates of autism tend to look lower, closer to one or two out of ten. Both directions still show that overlap is common enough that screening for each condition can matter.
These figures also have real life weight. People with both ADHD and autism are more likely to report learning difficulties at school, work challenges, and higher levels of anxiety or low mood. Families may spend more time attending appointments and arranging adjustments. None of this means a person cannot thrive; it does mean that a clear picture of needs helps services respond in a more fitting way.
Getting Assessed For ADHD, Autism, Or Both
If you relate strongly to traits from both lists, an assessment with a trained professional team can help you understand what is going on. The process will look different from one country or clinic to another, yet some parts are common.
Preparing For An Assessment
Before any formal appointment, it helps to gather information from your own life story. You might write notes about childhood behaviour, school reports, strengths, and things that felt hard. If parents, caregivers, or long term partners can safely share observations, those details can give extra context.
Many clinics use screening questionnaires as a first step. These are not enough on their own to diagnose ADHD or autism, especially when both may be in the mix. They simply guide the team toward areas that deserve more time in the interview.
What Clinicians Usually Ask About
During an assessment, a clinician may:
- Ask about childhood history, including when traits first became visible.
- Talk through school or work experiences, strengths, and stress points.
- Ask how you handle change, social situations, and sensory input such as noise or light.
- Look at attention, activity level, and impulsive behaviour across settings.
- Screen for anxiety, low mood, learning issues, sleep problems, or other health conditions.
This blend of history, interview, and sometimes formal tests helps the team decide whether ADHD, autism, both, or another explanation fits best.
Questions You Can Bring
It is easy to feel nervous during long appointments. Writing down questions can make it easier to leave with answers that feel useful. The table below lists prompts you might adapt for your own notes.
| Topic | Example Question | Why It Helps |
|---|---|---|
| Diagnosis | What signs made you think about ADHD, autism, both, or something else? | Gives a clear link between traits and any labels used |
| Overlap | Which of my traits fit ADHD best, and which fit autism best? | Shows how each diagnosis relates to day to day life |
| Other Conditions | Are there signs of anxiety, low mood, or learning differences as well? | Helps reduce the chance that anything major is missed during assessment |
| Next Steps | What practical changes or services do you suggest in the near term? | Turns the report into ideas you can act on soon |
| Work Or Study | How can I explain my needs to my employer, tutors, or school staff? | Helps you plan realistic adjustments in daily settings |
| Medication | If we try medication, how will we track benefits and side effects? | Sets shared expectations for any drug treatment |
| Follow Up | How often will we review my plan once we know more? | Clarifies how ongoing care will look over time |
Living With Both ADHD And Autism Day To Day
A label on its own does not change your daily life. What changes things is the mix of self understanding, adjustments, and help from others that flows from that knowledge. People with both ADHD and autism often talk about a few recurring themes.
Energy And Sensory Load
Bus rides, open plan classrooms, busy offices, or bright shops can drain energy fast when you live with both ADHD and autism. Movement and noise may pull your attention in many directions while your senses react strongly to each new sight or sound.
Simple steps can ease that load. Noise reducing headphones, sunglasses, or time in a quiet room between tasks can stop sensory build up. Clear routines for meals, sleep, and breaks protect energy even when schedules shift.
Routines, Interests, And Hyperfocus
Some people with both ADHD and autism describe strong, absorbing interests that feel joyful yet hard to switch away from. At the same time, ordinary tasks such as paperwork, tidying, or admin can feel nearly impossible to start.
Breaking tasks into short steps, setting timers, and pairing low interest jobs with music or movement can lower the barrier to action. It can also help to plan set times to enjoy deep interests without guilt, rather than seeing them as a problem to cut out.
Relationships And Communication
Misunderstandings can show up in both directions. You might interrupt without meaning to, miss cues that another person is bored or upset, or feel unsure how honest to be about sensory needs. Friends, partners, or colleagues might read this as carelessness when it is actually part of ADHD or autism.
Honest, plain language helps. So does sharing what you now know about your brain, at a pace that feels safe. Some people share short articles or checklists with relatives or managers. Others find it easier to describe a few concrete things that would help, such as keeping lights dimmer, giving written instructions, or agreeing on signals when a break is needed.
When To Reach Out For More Help
Labels such as ADHD and autism can bring relief, yet life can still feel heavy at times. Reaching out for help makes sense when:
- Everyday tasks such as washing, eating, or leaving the house start to slip.
- You feel overwhelmed by anxiety, low mood, or thoughts of self harm.
- Work, study, or relationships feel close to breaking point.
- You use alcohol, gaming, or drugs to numb distress more and more.
In those moments, a family doctor, mental health professional, or local crisis line can help you plan the next step. If you live in a place with waiting lists for formal diagnosis, it can still help to ask about practical adjustments or therapy based on your current needs rather than waiting for a label first.
If you ever feel at risk of hurting yourself or someone else, contact emergency services or the nearest urgent care service right away. Tell them about any past or current ADHD or autism traits so they can understand your reactions more clearly.
Bringing It All Together
So, can you have ADHD and autism at the same time? Yes, many children and adults do. Research shows that overlap is common, and health agencies now expect clinicians to check for both when traits suggest it.
You are more than any label, yet the right words can explain why life has felt a certain way up to now. With clearer language for your brain, you can ask for adjustments, choose places that fit you better, and build habits that honour both your challenges and your strengths.
