Why It’s So Important to Look for ADHD – Even If Your Child Is Already Diagnosed as Autistic
Posted on 15th April 2025 at 11:23
When a child receives an autism diagnosis, parents often breathe a sigh of relief, finally, an explanation for the differences they’ve seen. But what happens if that child also shows signs of ADHD? Many families stop short of looking into it. After all, “We’ve got the autism diagnosis, isn’t that enough?”
But recent research tells us something really important: when ADHD symptoms are also present in autistic children, it can make a big difference to how they think, behave, and cope with everyday life.
And if we don't recognise those ADHD traits, we risk missing opportunities to help.
What We’re Learning from Research
Studies are showing that when a child is both autistic and has ADHD traits, it can make everyday life even harder than autism alone.
Children with both conditions often:
Struggle more with remembering things, like instructions or conversations
Find it harder to manage daily routines like getting dressed or staying organised
Show more signs of restlessness, inattention, or emotional outbursts
Even though these children aren’t necessarily “more autistic,” the ADHD traits can make their autism feel more intense or harder to manage day-to-day.
So Why Does This Matter for You as a Parent?
If your child is autistic and you’re noticing signs of:
Forgetfulness or disorganisation
Seeming to “zone out” a lot
High impulsivity or restlessness
Struggles managing daily routines
…it’s not just “part of autism”.
These are often ADHD traits, and if left unsupported, they can add an extra layer of difficulty for your child.
When ADHD is identified, we can do so much more to help, from practical strategies to classroom adjustments, medication (if appropriate), or just better understanding their needs.
“But the doctor said it’s just autism…”
Unfortunately, many parents are told that ADHD doesn’t need to be explored once autism is diagnosed. Some professionals were trained using older guidelines that didn’t allow for both diagnoses at the same time.
But we now know better. Studies show that over 30% of autistic children meet criteria for ADHD, and many more have traits that impact daily life. It’s not rare, it’s common.
What Can You Do?
Trust your gut. If something feels “more” than autism, you’re probably right.
Ask about ADHD screening. Even if your child has an autism diagnosis, ADHD can (and should) be considered.
Don’t wait for a crisis. Early identification can make a massive difference in school support, friendships, and confidence.
