Hello! My name is Dr. Aida and I am glad to attend you on Healthcaremagic! Your son symptoms seem to be related to serious neurological disorders (epilepsy syndrome). It is OK to give steroids in such clinical condition, as they may help stop seizures and improve his situation. Anyway, it is difficult to judge on his future situation, based on what you refer. Genetic tests may be necessary. You should discuss with his doctor on the above issues and the exact diagnosis. Hope you will find this answer helpful! Best wishes!
