Thank you for your query,
Without a diagnosis of a neuro degenerative disorder it is very difficult to give advise.
But what is her present age?
Usually, the prognosis is poor in degenerative disorders and the child will end in vegetative state.
If you send your daughter complete clinical data along with reports and medication , I will try to advise you in a better way.
And you can discuss with the treating doctors regarding your concerns if possible with a Pediatric neurologist
Hope I have answered your query.
