IHC 2021 | Is migraine a brain multisensory disorder?

Koichi Hirata, MD, Dokkyo Medical University, Sōka, Japan, discusses whether migraine is a brain multisensory disorder. Sensory hypersensitivities such as photophobia, phonophobia, and osmophobia are common in patients with migraine. Hypersensitivities are important to understand the pathophysiology of refractory migraine. Additionally, these sensory hypersensitivity symptoms may reflect abnormal brain activity at the earliest stage of a migraine attack in the absence of pain. Dr Hirata highlights a study investigating the relationship between the burden of multiple sensory hypersensitivity symptoms and headache-related disability. This interview took place during the International Headache Congress 2021.
