I think you should ask the doctors to test the valparin levels in your son's blood. The control of fits
correlates well with how appropriate the drug levels are in his blood. Leviteracetam is known to produce sedation, and his symptoms are understandable. It may take a while for him to get to the level of the others in his class. Or, he may need special school. Involve the school counsellor and the neurologist
in all these matters so that he gets the best out of his life.
