Self-perceived attention difficulties are associated with sensory hypersensitivity in migraine.
Revue neurologique(2020)
摘要
BACKGROUND:Attention is the process which enables to preferentially select salient or relevant stimuli and to attenuate the response to irrelevant incoming stimuli. Migraine is characterized by both attentional alterations and an abnormal sensory processing to external stimulations. The aim of the study was to investigate potential interactions between self-perceived attentional difficulties and sensory hypersensitivity in migraine patients.
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 self-perceived attentional difficulties in migraineurs (P=0.002), but not with migraine disability or levels of anxiety or depression. Ictal and interictal sensory sensitivities were significantly correlated in migraineurs within visual (P<0.001), auditory (P<0.001) and olfactory (P=0.001) modalities.
CONCLUSION:This study shows for the first time an association between self-reported attentional difficulties and multimodal sensory hypersensitivity. Studies combining behavioral and physiological measures of sensory processing and attention processes are necessary to further understand the peculiar vulnerability of migraineurs to sensory stimuli.
