A well-known neurologist, Oliver Sacks, had written quite a bit about this. He wrote a lot on interesting neurological topics. I have read his book, Migraine, and it touches upon these points quite well. He even talks of a condition he calls "migralepsy."

He/his clinical/research observations, theories and his writings are outstanding!
Just my own very humble opinion.

I have BP. I have had all types of migraine activity, including, but not limited to, migraine equivalents, "migralepsy," etc., etc.

I have also been repeatedly evaluated for Temporal Lobe Epilepsy because I often have the symptoms and the experiences associated with TLE. For quite awhile, I had been put on Tegretol for both migraine and for TLE symptoms.

I firmly believe some interesting correlations between these types of conditions likely exist!!!
