I have just been diagnosed with migraines. I also have epilepsy. I am have never had migraines before. Mri and CT already done.?

Migralepsy. People with epilepsy have an increased risk of having migraines. Sometimes, when the migraines are frequent, certain epilepsy medications such as topiramate, divalproex sodium, and zonisamide can be used to prevent both conditions.
Concerning. New onset of migraines (usually after age 40) does suggest another diagnosis, so an MRI and ct are important to do. Especially with seizures as well (which do not go with migraines usually) something is likely going on. Other causes can be drugs (prescribed and illegal), infections, vasculitis (inflammation of blood vessels), and some things MRI should have seen. May need esr/ana(blood), spinal tap.
