Hi, I am new to this board, and to epilepsy!
I am not sure what kind of seizure your grandson is having, but it sounds to me like absence seizures. My daughter has the same symptoms!
She was diagnosed just this past oct.
Is your grandsons seizures a result of fever? ( febrile)?
I to have never heard of doctors putting into coma! If his seizures are absence seizures, there is little fact that it will cause brain damage!
Have they done a eeg since he has been in hospital? This will show if there is brain damage! It can also show if there is a history of seizures!
Please keep us posted as to how he is doing!
Best wishes... Pj
