It is clear that visual snow syndrome is a disorder of the central nervous system. However, the underlying pathophysiological mechanisms remains elusive. Here, we reveal no evidence of gross morphometry changes in the visual snow syndrome brain, but widespread changes in the microstructure of the GM, the most notable of these occurring in caudal regions including the occipital cortex. None of these changes are directly associated with the co-occurrence of migraine. While we were unable to determine the specific brain tissue that underlies microstructural changes, they do focus further investigations, contributing significantly to our understanding of visual snow syndrome.
