...migraine patients, the problem is quite different; while sufferers can pinpoint certain triggers (food, sleep patterns, stress, alcohol), no one's really sure what exactly causes the condition in the first place. The headaches can last hours - sometimes days - and often come with nausea, vomiting, sensitivity to sound and light, and, perhaps most strangely of all, distorted sensory perception, especially vision. Add to that a link with certain other blood conditions and neurological conditions, and it's no surprise that researchers are still perplexed about the headaches - or that patients seem to find treatment so hit-and-miss...
...Henry Schipper, 49, of Venice, Calif., the first warning signs are mild and almost pleasant--a giddy light-headedness that evolves into what he describes as a "happy series of energetic moments." Then for about 15 minutes his eyes play tricks on him, and a wall of shimmering light obscures his field of vision.

Migraines are usually accompanied by either nausea and vomiting, as they were for TV producer Schipper, or extreme sensitivity to both light and sound. By contrast, patients suffering from tension-type headaches may react badly to either light or sound but not both...
...much is happening all at once during a migraine that it has been hard to pinpoint what sets off the trigeminal nerve. Some scientists are focusing on a wave of electrical activity that spreads across the brain just before a migraine and triggers the aura--the shimmering light show experienced by 1 in 5 migraine patients. Others wonder wheth-er there is some kind of migraine generator buried deep within the brain stem. Even when researchers think they know the order in which different parts of the brain turn on during an attack, they can't always be sure...
...When the Roehrkasse e-mail came to light, he told the press that Gonzales had been upset because he believed that "Bud Cummins' removal involved performance considerations." But on April 15, Congressional sources tell TIME, Gonzales' former chief of staff Kyle Sampson told a different story. During a private interview with Judiciary Committee staffers Sampson said three times in as many minutes that Gonzales was angry with McNulty because he had exposed the White House's involvement in the firings - had put its role "in the public sphere," as Sampson phrased it, according to Congressional sources familiar with the interview...
