Explores hemiplegic migraine diagnosis in emergency settings, suggesting improved imaging techniques could aid recognition.
Hemiplegic migraine is an uncommon type of migraine with aura caused by abnormalities in calcium ion transport. Because its symptoms overlap with stroke, patients are often initially treated in the emergency room. There, standard anatomic brain imaging is normal. Perfusion imaging, if performed, can aid in the diagnosis. However, the diagnosis is often made clinically based on standard diagnostic criteria.
