New Insight into the Neural Mechanisms of Migraine in Adolescents: Relationships with Sleep

Adolescents with migraine have different functional connectivity of the amygdala compared to individuals without migraine. Considering that sleep is often disturbed in those adolescents with migrane, this study examined if measures of subjective and objective (actigraphic) sleep difficulties mediate alterations in amygdalar connectivity in adolescents with migraine compared to healthy adolescents. Twenty adolescents with migraine and 20 healthy controls completed surveys about their headaches and overall sleep quality, sleep hygiene and perceived sleep difficulties, wore a wrist-worn actigraphy, and underwent an MRI scan.Adolescents with migraine differed from healthy controls only in perceived sleep difficulties related to sleep initiation and maintenance (pPerspectiveThis article evaluates the role plays by sleep on neural alterations in adolescents with migraine. It indicates that neural alterations due to migraine are not related to alterations in subjective and actigraphic sleep difficulties. This advances the understanding of the mechanisms underlying pediatric migraine and can potentially advance migraine management.
