Seizures are not even what is considered mental illness. They are a manifestation of a physical, medical problem that involves messages sent by the brain to the body. Epilepsy and febrile convulsions are only two examples of conditions that manifest as seizures.
Do not go to anyone who can remove shin daletim or any other sort of alternative practitioner if you have repeated seizures. Go to a board certified or otherwise qualified neurologist. Fast. I didn’t bother when it happened to me, but you probably should get an EEG or even an MRI after a febrile convulsion and you definitely should have your child examined after even a one-off seizure.
