If the present drugs are inadequate, then additional anti-seizure drugs may be given or the dose of the present drugs adjusted. The lack of
sleep may also contribute to this, since neurons are easily depolarized
and excited by the lack of sleep. Other drugs would include carbamazepine, neurontin, or valproic acid, but I suggest you talk to her neurologist about this first.
I hope the seizures can be controlled soon. Regards and God bless.
