Patients with migraine have a thickening in two areas of the brain associated with motion processing, according to new US research.

The study, conducted by scientists from Harvard Medical School, scanned the brains of 12 people who had migraine without aura, 12 people who had migraine with aura and compared them with 15 controls.

Findings show both groups of migraine patients have a thickened cortex in two areas of the brain, called V3A and MT compared with healthy controls.

The areas of the brain are permanently thicker -regardless of whether patients are having an attack or not, the authorsadd.
