You must know that the diagnosis of autism
is made usually before 3 years of age and ideally around 18 months of age. If your son is 14 years old, it means that the symptoms must have started in early childhood itself. Did you get your son checked during that time by any doctor ? And febrile convulsions
is not a diagnosis in a 14 year old. The age group for febrile convulsions is between 6 months and 5 years. So i feel after reading your entire history, there is indeed something wrong somewhere. Either in making a correct diagnosis of your child or in the history itself. Lastly valparin is currently not indicated for febrile convulsions. So kindly get the entire history reviewed.
