Objectives:The aim of the study was to investigate potential interactions between sensory hypersensitivity and attentional difficulties in migraineurs.
Methods:Forty-six episodic migraineurs without aura and 46 healthy controls filled out questionnaires on self-perceived attention difficulties and self-reported sensitivity to visual, auditory and olfactory stimulations.Results: Compared to controls, migraineurs reported significantly higher levels of attention difficulty and sensory sensitivity. Sensory hypersensitivity correlated significantly with attentional difficulties in migraineurs (p=0.002), but not with migraine disability or levels of anxiety or depression. Ictal and interictal sensory sensitivity were significantly correlated in migraineurs within visual (p<.001), auditory (p<.001) and olfactory (p=.001) modalities.
Conclusion:Self-reported attentional difficulties, multimodal sensory hypersensitivity and the association between both may reflect the fact that external stimuli engage attention in an exacerbated manner in migraineurs, yielding distraction.
