FIGURE 1.

Migraine is comorbid with several chronic and difficult to treat disorders of sensory processing, such as visual snow syndrome (VSS), chronic tinnitus, persistent postural‐perceptual dizziness (PPPD), and fibromyalgia. Having migraine involves recurrent headache attacks of migrainous phenotype, as well as interictal difficulties during multimodal sensory processing. Migraine might be a common link to processing disorders of more specific modalities, such as the visual (i.e., VSS), vestibular (PPPD), auditory (tinnitus), and pain system (fibromyalgia). This might also partly explain the clinical overlap of these disorders and why they are often related to each other.
