Can a Child Have Both Epilepsy and Developmental Delay?

When a child has seizures and is also slower to reach milestones, parents often wonder if it's one thing or two — and what that means for the road ahead.

In short

Yes — a child can absolutely have both epilepsy and developmental delay together, and this combination is more common than many families realise. Sometimes the same underlying brain difference causes both; sometimes the seizures themselves, or how they're managed, affect learning and development. The reassuring truth is that both are addressable: with the right medical care for seizures alongside developmental therapy, very many children make meaningful progress.

Understanding how they connect

Epilepsy and developmental delay can occur together in a few ways. A shared origin — such as a genetic difference, an early brain injury, or a structural difference — may give rise to both at once. In other children, frequent or poorly controlled seizures can interrupt the brain's learning at exactly the ages when skills are forming fastest. This is why seizure control is itself developmental care: settling the seizures often creates the calm, available brain a child needs to learn.

A few important points for families:

• Epilepsy is a medical condition first. Seizures need prompt assessment and ongoing management by a paediatric neurologist — this comes before, and runs alongside, any therapy.
• Developmental delay is not destiny. Delay describes where a child is today across speech, movement, thinking, social and self-care skills — not a ceiling on where they can go.
• Both can be supported in parallel. Once seizures are stable, structured therapy helps the developmental side catch up.

When to seek help

If your child has had any seizure — staring spells, stiffening, jerking, or unusual repetitive movements — see a doctor promptly; seizures always warrant medical review. If you are also noticing delays in talking, walking, play or social connection, mention both, because the two together change the plan. The goal is a team approach: the neurologist manages the epilepsy, and developmental therapists build the skills.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or an online form, and always coordinated with your child's medical team for the epilepsy itself. With 25 million+ therapy sessions and 4.95 lakh+ families served, we work alongside your neurologist so seizure care and developmental progress move together. Start by understanding where your child stands today with our clinician-administered assessment, explore how therapy supports children with developmental delay, and see how our programmes work.

Next step — Speak with your child's doctor about the seizures, then book a developmental assessment so both sides of the picture are cared for together.
