AHS 2023 | Cerebral function changes in migraine

Chia-Chun Chiang, MD, Mayo Clinic, Rochester, MN, describes a recent study that utilized the King-Devick Test (KDT) to study migraine. The study involved 30 participants who recorded KDT scores at least three times daily for four months. Electronic headache diary data was also collected, which included the state of the headache and general health information at the time of each recording. Over 5000 data points were collected and analyzed. They showed significant changes in KDT scores between the interictal phase and prodrome, postdrome, migraine, and non-migraine headache phases, which reflects a change in cerebral function. Subgroup analysis also found that cerebral function changes are more prominent in migraine with aura compared to migraine without aura and in migraine compared to non-migraine headache. This interview took place at the American Headache Society 2023 meeting in Austin, TX.
