Hi, I Suffer From Migrain With Aura, And During My

Hi, I suffer from migrain with aura, and during my attack (which can last up to an hour or even for 3 days), but during the migrain i can not even remember my name, let alone say it. I become very clumbsy as well. Is it common that this happens, should i be more concern about my headaches when this happens? I have suffered from migrains since i was of the age of 10, and im 40 now.
