Abnormal EEG having fits. Please advise.

2 days back we observed behavioral changes in her. She was repeating statements and had difficulty in normal activities. We measured bp it was 170/110 . Consulted doctor and gave the advised medicine amlopress at and lonazep.25 but after taking these she had memory loss and could not even recognise family members. She was in drowsy state, semi conscious type. We went to hospital she was admitted and test were done. Mri was normal, other test were normal. EEG had some abnormal changes . Doctor said she is having fits in brain and the cause for that has to be identified. But after several other test they have not reached any conclusions . Her state is same for last 2 days. Tests pending are CSF and auto immune panel. Don't know what to do please advise.
