Most people who experience migraine aura have had it for years before recognizing what it is. The blind spots, zigzag lines, and tunnel vision are the most familiar patterns, but research documents 34 distinct aura signals, many of which look nothing like the classic visual disturbances. What all of them share is the same underlying mechanism: a wave of electrical activity called cortical spreading depression moving across the brain, shifting ions as it travels. Understanding what each pattern looks like, how long it lasts, and why some auras never produce a headache gives you something more useful than a diagnosis, it gives you a window to act.
