I am assuming that if in fact your daughter is having psychological seizures or psychogenic nonepileptic seizures (PNES), you are aware that the anticonvulsant medications will not help. Is your daughter having other types of seizures? How do you know that your daughters seizures are pseudo seizures, which is old terminology and rather insulting which I think is why it was changed. Sadly if someone is experiencing seizures and they have an EEG (electroencephalogram) and it turns out normal some doctors make the assumption that the patient is having Psychogenic seizures which often is not the case.
Wishing you your daughter and family the best of luck,
