Thank you for your query.
Your child has delayed developmental milestones and features of autism
.There is a lack of understanding,comprehension and production of words.
You have not mentioned whether an MRI
scan of the brain has been done or whether there was any history of birth asphyxia
These drugs may have some palliative role in this disorder.But the mainstay of this problem is the proper behavioural therapy and training of the child.
If you have any further queries you are free to consult me.Hope this answers your query.Wishing your child well.Have a nice day.
