When you find a way to bypass the genetic disorder problem, let me know. Unless you find a way to alter your child's (or your) genetics, then the answer is no.
The immediate complication of epilepsy is simply the risk of getting a seizure :-)
Generally epilepsy is controlled rather than cured. Children often stop getting seizures as they grow older. However, every case is different so each individual would have to be monitored by a doctor to see what happens.
Anything is possible.
It isn't passed from one dog who has epilepsy to another healthy dog that doesn't have epilepsy by contact or any other way except genetically. Epilepsy can be passed on genetically. Such as the Sire or Dam of the pups can have epilepsy & the pups' odds of getting epilepsy are much higher.
No. Spasm can sometimes be because of Epilepsy
yes, epilepsy cause by the disruption in the conductance of the impulses by the nerve cells. Imbalance between the inhibition and the excitation of the nerve impulse in the brain cause epilepsy.
There are many reasons and causes of epilepsy, so it is not really possible to say what can be done to avoid it. It isn't like an infectious disease that you can get vaccinated against. Only about 1 in every 200 people have some form of epilepsy. Something like a head injury can result in epilepsy, so you could say that trying to avoid getting any sort of a serious head injury in your lifetime is one way or trying to avoid getting epilepsy.
Epilepsy is not an infection or a virus or anything like that, so the immune system is not relevant to it. You cannot "catch" epilepsy from someone. So the immune system does not respond to epilepsy. There is nothing that it can do.
By proper medication, or extreme cases surgery.
If someone gets some damage to their brain, this can result in someone getting epilepsy. So if someone had a aneurysm in their brain and some damage was done, it is possible that epilepsy could develop epilepsy, but it is not certain that it would happen.
Not remembering anything that happened.
I would not give anything to your dog unless it is recommended by a veterinarian.
