Thank you for your query.
Following head injury
doctors do prescribe an anticonvulsant medicine. As your daughter did not have any convulsions and her EEG is normal the medicines were stopped. I would like to wait and watch rather then give Vinlep for twitching of the eyes.
Regarding your concern for Vinlep affecting your daughter's studies, physical and mental development it is very difficult to predict it. Usually the medicine does not affect in majority of the cases.
I hope I have answered your query to your satisfaction.
