Hi Mr. lybrate-user. I hope you want to say Mirgi ki bimaari matlab Convulsions.
Your baby has small head size and convulsions. Also baby is recieving Epival
which is a good anti epileptic drug. Your baby also underwent MRI brain twice. This all suggests that she has some organic and functional problems which is not good for me to guess without examining your child and going through all the investigation reports. So it is not possible to comment on prognosis of the disease.
Children of 3.5 year old are not fluent
in speaking also they do make a sentence of 2-3 words only. Many times only parents can understand what child wants to speak. Your baby has some issues and she is on medication hence we don't expect her to outperform in speaking. If she understands your spoken language and follows commands also if she is able to ask for things she wants then there won't be any difficulty for her to catch up speaking in near future. Speak to your paediatrician when you consult him next time.
