What Is a Hemiplegic Migraine?

Read Transcript

The hemiplegia is typically another migraine aura, and we often see are sequences of aura. So if you've hemiplegic migraine, you may first develop a visual aura. Maybe you'll see some zig-zag lines or some blind spots, and then perhaps become numb, and then perhaps become weak, and that has to do with the march of the the wave called cortical spreading depression, going across the brain typically from the back to the front of the brain.

And if we get a good history of that and we can see this recurring sequence of auras, we're very comfortable that it's hemiplegic migraine and many of these cases occur in families where many members of the family have the same disorder, and it's easier, and a little more comfortable making the diagnosis.
