Visual Tests to Investigate Altered Brain Function in Migraine

Grant number: 509208 | Funding period: 2008 - 2011

Completed

Abstract

Migraine is a very common and disabling neurological condition that often involves visual symptoms. This project will study vision in people who experience migraine, to determine whether brain function is altered by a migraine event or in between migraines. Understanding the visual consequences of migraine provides insight to the neural processes causing migraine, and also those underlying less common but more sinister outcomes of migraine such as stroke and peripheral vision loss.
