<s>[INST] My daughter is 27 years old and has had 10 seizures since March 2014. Testing has been done, no physical reason for the seizures. However, she has been experiencing acute stress and anxiety which I think is causing the seizures. She has been prescribed Keppra and I would like to know if she can add Theanine to help her with lower her stress level. Will Theanine interact with Keppra? [/INST] Hi.I understand your concern.EEG and MRI can help for confirmative diagnosis.Stress can worsen seizure and can be treated with anti convulsant  with anxiolytic.Keppra can help to control seizure. Anxiolytic like lorazepam can help in both convulsion and stress.Thiamine is vitamin and it can help to supplement.It can not help in stress and convulsion and can be given with keppra.No need to worry.Take advise from your treating doctor.I hope I have answered your question.Thank you. </s>
