How is Childhood Epilepsy diagnosed in a child?

The word "epilepsy" can frighten any parent — but understanding how doctors reach that diagnosis turns fear into a clear, manageable path.

In short

Childhood epilepsy is diagnosed by a doctor — a paediatrician or paediatric neurologist — not through developmental therapy. The diagnosis rests mainly on a careful history of the events (often supported by a phone video you record at home), a physical and neurological examination, and tests such as an EEG (a painless recording of brain activity) and sometimes an MRI brain scan. Epilepsy is generally considered when a child has had two or more unprovoked seizures, or one seizure with a high chance of more. If you suspect your child has had a seizure, this needs prompt medical attention, not a wait-and-watch approach.

How doctors reach the diagnosis

The story matters most. Most seizures are over before you reach a doctor, so what you describe — and any video you can capture safely on your phone — is the single most valuable clue. Note what happened just before, during and after: stiffening, jerking, staring spells, lip-smacking, eyes rolling, confusion afterwards, and how long it lasted.

Examination and tests may include:

• EEG (electroencephalogram) — small sensors on the scalp record brain wave patterns; completely painless and a cornerstone test.
• MRI of the brain — looks for any structural reason behind the seizures.
• Blood tests — to rule out fever, infection, low sugar or salt imbalances that can mimic seizures.
• Sometimes a sleep-deprived or longer-duration EEG to capture activity that a short test may miss.

Not every shaking or staring episode is epilepsy — breath-holding, fainting, and febrile (fever-related) seizures are common and often not epilepsy. That is exactly why a doctor, not a parent or an app, makes this call.

When to seek help urgently

Call for emergency medical help if a seizure lasts more than 5 minutes, if breathing looks difficult or lips turn blue, if one seizure follows another without recovery, or if it is your child's first-ever seizure. For any suspected seizure, see a doctor promptly — epilepsy is a medical condition, diagnosed and treated by physicians.

The Pinnacle way

Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — and epilepsy itself is always diagnosed and managed by your medical doctor. Where seizures affect a child's speech, learning, attention or movement, our team supports development alongside that medical care: explore childhood epilepsy support, understand your child's developmental starting point, and see how speech therapy can help when communication is affected.

Next step — If your child has had an unexplained episode, see a paediatrician or neurologist promptly; and if development needs support alongside, book a developmental assessment with a Pinnacle clinician.
