1.2.2 Migraine with brainstem aura

A man reports his third such episode overall since he was seventeen. He describes a strange, welling-up sensation that spreads over the course of around sixteen minutes rather than appearing all at once, quite different from any numbness or fading of feeling. During this time he has twice become briefly vacant and slow to respond to being spoken to, and on one occasion he noticed seeing two of everything for a short spell. His speech is not slurred but he struggles to get the right words out, as though he knows what he wants to say but cannot access it. He is adamant that his limbs have never felt weak during any of these episodes, and that he has never lost vision in one eye specifically.
