When "Complex Migraine" Means Stroke

A woman in her early forties develops sudden slurred speech, right-sided weakness, dizziness, and vomiting on a summer evening. Her mother calls 911 and tells the dispatcher she thinks her daughter is having a stroke. EMS brings her to a certified primary stroke center — a hospital with alteplase, CT imaging, and tele-neurology, all ready and operational. The emergency physician examines her, considers the picture, and lands on a diagnosis: complex migraine. No stroke alert. No NIHSS. No neurology consult. By the time a neurologist is finally called, the tPA window has closed. Four days later, she is dead.In the debut episode of The Cognitive Autopsy, Bryan walks through the clinical sequence step by step, Sarah unpacks how anchoring on a benign diagnosis becomes a legal and regulatory case, and Paul brings the frontline clinical perspective: why “complex migraine” is one of the most dangerous phrases in emergency medicine, how anchoring bias and premature closure quietly shut down a stroke workup, and the one thing any clinician can do on the next shift to keep the differential open long enough to catch the patient who is actually stroking out in front of them.Educational purposes only.
