Facial Tics and epilepsy

I have a 10 year old son, he was diagnosed with epilepsy when he was 8 years old, he has been an Lamotrigine now for almost 2 years and has been seizure free for 18 months, just recently he has developed a range of facial tics, has anyone else found this with their children and could it be linked to his epilepsy or the medication?

Hello Jeg,
My daughter is 9 and on Levetiracetam (Keppra) which has generally controlled her seizures very well for 18 months. She developed a vocal tic (grunting noise) about 9 months after starting to use Keppra. I asked our epilepsy team about it and they said the tic is not likely to be a direct side effect of medication, but an indication of underlying stress that could be connected to her epilepsy - for example, the learning difficulties she experiences.
