Hemiplegic migraine is similar to Migraine with aura except that it involves motor weakness that cannot easily be distinguished from stroke without brain scans.
The aura must consist of both
- motor weakness (or paralysis)
- one other visual, sensory, or speech aura symptom
With at least two of these characteristics:
- at least one aura spreads over 5 minutes, and/or two or more auras occur in succession
- each non-motor aura lasts 5-60 minutes and motor symptoms last less than 72 hours
- at least one aura occurs only on one side of the body
- headache accompanies or follows the auras within 60 minutes.
