Understanding Brain Entropy Changes in Migraine Sufferers

Research Summary

A recent study published in medRxiv explores how brain entropy changes in individuals with migraine, providing new insights into this complex neurological disorder. Brain entropy, which measures the complexity of neural dynamics, is notably reduced in migraine sufferers, indicating diminished neural adaptability. This reduction is most pronounced in chronic migraine, particularly in sensory, attentional, and default mode regions. Interestingly, during migraine attacks, there is a partial restoration of entropy, suggesting a temporary recovery of neural adaptability through weakly chaotic dynamics. Additionally, symptoms like phonophobia and nausea are linked to increased entropy in specific brain regions, offering potential therapeutic targets.
