Seizure types explained

Focal, generalised tonic-clonic, absence, myoclonic, atonic — what each looks like in plain English.

5 min read

Doctors group seizures into two big families: focal (starting in one part of the brain) and generalised (involving both sides from the start).

Focal seizures

  • May cause twitching on one side, strange smells/tastes, déjà vu, or fear.
  • The child may stay aware (focal aware) or lose awareness (focal impaired awareness).

Generalised seizures

  • Tonic-clonic — stiffening then jerking, often with loss of consciousness. The classic "convulsion".
  • Absence — brief blank stares lasting seconds. Often mistaken for daydreaming.
  • Myoclonic — sudden jerks of arms, legs or whole body.
  • Atonic ("drop") — sudden loss of muscle tone, child falls.
  • Tonic — sudden stiffening.

Why naming matters

The type of seizure guides which medication is most likely to work. Some medications that help one type can actually make another type worse — which is why an accurate diagnosis matters.

Tracking

Keep a diary of:

  • Date and time
  • How long it lasted
  • What happened before (tired? unwell? missed medication?)
  • How long until your child seemed back to normal
  • Anything unusual
