Researchers reviewed imaging data to see how the cerebellum, a part of the brain that helps coordinate movement and balance, relates to migraines. They looked at patients with various types of migraines, including vestibular migraine and medication-overuse headache. The review looked at how these patients responded to CGRP-directed treatments.
Imaging showed that the cerebellum is part of a large network involved in migraine. While some studies showed changes in the cerebellum during the migraine cycle, these studies used very small groups of people. Other tests showed that common migraines do not always cause a general deficit in this part of the brain.
It is important to note that while the cerebellum is involved in migraine networks, it is not currently considered the primary source of a migraine attack. It is also not yet a confirmed target for specific treatments. Because the data comes from small groups and different testing methods, these findings are not yet enough to change standard medical practices.
