Migraine Mistakes: Error Awareness

Abstract

Error awareness or detection is the conscious and subconscious processing to evaluate physiological signals that are different from a baseline or homeostatic level. Migraine is a unique neurological disorder in which there are repeated attacks interspersed by attack-free periods. These attacks are dynamic and multidimensional in the sense that sensory, affective, autonomic, and cognitive functions are altered and these changes evolve differently before (pre-ictal), during (ictal), and immediately after (post-ictal) an attack. Thus migraine serves as a model disease to understand how the brain monitors and react to the presence of errors.
