Migraines: What causes them and how to find relief

We’ve been trying to cure migraines – without much success, until relatively recently – for as long as we’ve been able to identify them as a distinct ailment. The Ebers Papyrus, a scroll dating back to 1550 BC that mentions a “disease of one half of the head”, suggests anointing the scalp with fried catfish; Galen, the second-century Roman physician whose term “hemicrania” evolved into the modern word, recommended bloodletting (this, to be fair, was his answer to a lot of things). By the 20th century, doctors were suggesting repressed emotions might be at fault, leading to suggestions that women – who suffer from migraines far more than men – were simply too fragile and neurotic. As recently as a couple of decades ago, “vascular theory” – the idea that blood vessels in the brain expanding and contracting were to blame – was still the standard explanation in many medical schools.
