Focal seizures
Start in the temporal lobe, affecting hearing, speech, memory and emotions
Focal seizure presentation
Hallucinations
De ja vu
Flashbacks
Auto pilot
Management of focal seizures

Normally in children as juvenile myoclonic epilepsy
Treatment of myoclonic seizures
First line: sodium valproate
Second line: lamotrigine, levetiracetam or topiramate
