What is a complicated migraine?
A complicated migraine is a migraine episode during which there are non-pain-related neurologic signs. The most common of these are weakness or sensory changes (usually numbness or tingling) on one side of the body. But speech arrest (difficulty speaking or understanding), vertigo, and visual changes have also been described. The main difference between a complicated migraine symptom and an aura is that in complicated migraine, the changes are concurrent with the headache while in aura, they precede it. Complicated migraines have some other implications for your health which make it a good idea to seek neurologic advice regarding prevention of these episodes.
