Hello Dr Santosh, My Son Is Nearly 4yrs Age But

Hello Dr Santosh,
My son is nearly 4yrs age but is yet to begin speaking...he makes some indistinct sounds and his other milestones are fine. Uptil now he has had about 3-4 episodes of FEBRILE SEIZURES i.e. soon after his body temp crossed 99C, he went into fits each time. But around July'14, we met a paed neurologist who ran some MRI/EEG etc and thinks that his EEG is abnormal...hence recommended Valperin200 & Ecod which he has been taking.
