Thank you for posting your question here, I will answer it as best I can.
I recommend you see a doctor right away so that he can run some tests to determine what is going on with your daughter.
I would recommend a blood test
, urine analysis and either an MRI/CT of her brain. An EEG might be required as well.
Its only after running these tests that we can start narrowing down what is wrong with her, because as it is, it could be any number of things.
Please do post the results of the tests they run on her, if you want a second opinion
on the results.
I hope this answered your question.
