[|Human|] what is the reason to occuring of tonic-clonic secure ? if it is cureable ? what is the symptoms before occuring of secure ? my friend has secure during only sleeping what is the reason?
[|AI|]  Hi, Tonic clinic seizure or for that matter any type of seizure is due to increased voltage or current in the brain which occurs suddenly because of brain cell membrane weakness or problem. So medicines are given to correct it. It is 96 to 98% curable after 3-5 years of continuous treatment with optimum dose of the Chat Doctor.  There are various stimulating factors which cause the voltage in the brain to go up and one of it is sleep, so your friend is getting seizures only in sleep which we call nocturnal generalized seizures. Please meet a good neurologist and get proper and early treatment as early the treatment the better is the outcome in epilepsy.
