Hello! Thank you for asking on HCM! I would like to have a better description of her migraine attacks and her seizures. Has she had seizures before? I would like to explain that migraine attacks and seizures can coexist, because of a similar hyperexcitability of the brain causing both of these disorders, but they may also be caused by a brain lesion (a tumor,an infection, an aneurysm, a vessel malformation) which can be related to this clinical scenario. I would recommend you to consult her with a neurologist for a careful physical examination for neurological signs. A routine blood test, an EEG and a brain MRI scan are necessary to establish the diagnosis. Hope to have been helpful! Greetings! Dr. Aida
