Autism and Epilepsy: What Parents Need to Know

Autism and epilepsy share some of the same underlying differences in how the brain develops, which is why epilepsy is more common in autistic children than in the wider population. There tend to be two ages when it's more likely to appear: early childhood and adolescence.

It's important to keep this in perspective: most autistic children will never have epilepsy. But because it's more common, it's worth knowing the signs so you can act if you ever need to.

Seizures are much more varied than many people expect. They can include:

• Convulsive seizures — stiffening, jerking, loss of consciousness.
• Absence seizures — brief 'blanking out' or staring, stopping mid-activity, not responding for a few seconds.
• Brief jerks of the limbs, or sudden drops/falls.
• Unusual repetitive movements, lip-smacking, fiddling, or confusion.

Some of these can look like daydreaming or stimming, which makes them easy to miss. Suspect a possible seizure if your child can't be brought out of the episode, seems confused afterwards, or it happens in a consistent, out-of-character way. When unsure, film it and show your doctor.

If you think your child may have had a seizure:

• See a doctor. A first suspected seizure should always be assessed.
• Keep a record — a phone video and notes of time, length and what you saw are extremely helpful, because children rarely have a seizure during the appointment.
• Diagnosis may involve a specialist and tests (such as an EEG).
• Management — epilepsy is usually well controlled with medication; your team will guide dosing and a seizure plan.
• Tell school and share the seizure plan so staff know what to do.

With the right plan in place, most children with epilepsy live full, active lives.

Epilepsy is more common in autistic people than in the general population, which is why we cover it. Note what you saw, how long it lasted, and video if it is safe. Tell the GP or emergency clinicians that your child is autistic so communication during recovery is adjusted. Who should skip this: using the internet instead of emergency services while a long seizure is happening.

This table is a parent prompt, not a diagnosis. For UK first-aid steps and when to call 999, use HealthAnswers on epilepsy alongside this page — their figures on medicines and driving are general, not a plan for your child.

Share the about my child sheet so new staff do not treat post-ictal confusion as 'behaviour'. Put the plan in the bag and with the SENCO. After a first event, keep a log: date, time, length, what you saw, recovery. That log is more useful than a vague 'they had a funny turn'.
