1.4.4 Migraine aura-triggered seizure

A 22-year-old university student reports two lifetime episodes of a sudden collapse at home. Before each one he notices sparkling lights across his vision, a clearly positive phenomenon, followed moments later by slurred, jumbled speech that he cannot correct. This warning builds gradually over some seven minutes rather than starting abruptly, and left untreated it typically lasts around half an hour, some thirty-two minutes or so by his own reckoning, before fading. On both occasions, while the sparkling lights and speech disturbance were still present, he suddenly fell to the floor with generalised limb stiffening and jerking that his flatmate timed at just under a minute and a half, followed by drowsiness. His flatmate has now seen both episodes and gave the same description each time, confirming the fall happened while this visual and speech warning was still ongoing.
