What are febrile convulsions?
- Seizures/ fits as a result of a fever/hyperthermia
- Typically in ages 6 months to 3 years old
- Lasts under 5 minutes (may take child 10-15 minutes to wake up after seizure)

Hyperthermia e.g. fever
What do you do if febrile convulsion lasts for more than 5 minutes or that there is no recovery in between febrile convulsions?
Treat as SE
Dravet’s syndrome treatment
Often confused as febrile convulsions occurs due to hyperthermia too
