Digital Biomarkers for Objectively and Remotely Monitoring Migraine


About this study

Changes in vision are commonly reported by patients during migraine attacks. Even in patients that do not report changes in vision, we have noted objective changes as demonstrated by changes in the King-Devick Test (KDT), a quantitative measure of rapid eye movement; which was 6.5 seconds slower (SD 7.6 seconds, p<0.001) during a migraine attack compared to between migraine attacks. This study aims to evaluate changes in timed rapid number naming using the KDT during the twelve hours prior to a migraine attack (“pre-attack” phase) and during the migraine attack compared to the between attack phase. Accurate prediction of an impending migraine attack based on changes in the KDT would allow for future studies that determine the effectiveness of proactively treating migraine attacks during the very early “pre-symptomatic” stage, a strategy that would likely provide superior outcomes compared to current standard-of-care.
