Welcome to health care magic forum,
This memory weakness is due to medicine or due to disease also. She is taking valparin since 6 month and she had no episode in between so consult to your doctor and ask when to stop medicine. and also do EEG to know prognosis.
If fit is recurrent then take alternative medicine like homeopathy
which can treat it without any side effect and permanently.
