"In one instance, a reference to a neural phenomenon called "spreading depression" caused him to look for articles with that term in their titles. Reading those pieces, he found that magnesium was often mentioned as preventing this spreading depression. Other connections to magnesium deficiencies started to appear, so he dug further. In a 1988 paper on his research, he wrote, "One is led to the conjecture that magnesium deficiency might be a causal factor in migraine."

Today, Dr. Swanson's work is considered significant both for migraine studies and for text mining. The link between the headaches and magnesium deficiency was soon backed up by actual experiments."
