Migraines and Phono- Photophobia

Do you experience migraines or know someone who does? Migraine sufferers often report increased sensitivity to sound and/or light during a bad headache. Anne Woodhouse and Peter D Drummond of Murdock University in Western Australia studied individuals with and without migraines to determine if phonophobia (sound) was a manifestation of loudness recruitment. The results showed that both auditory and visual discomfort thresholds decreased substantially during attacks of migraine (as compared to individuals who did not experience migraine). The findings did not support the view that phonophobia in migraine is a manifestation of loudness recruitment. Some type of disruption of central sensory processing mechanisms during migraine, however, appears able to increase sensitivity to quiet sounds and contribute to both phonophobia and photophobia.
