Sensorineural hearing loss is caused by damage to the cochlea in the inner ear or damage to the nerve pathways from the inner ear to the brain. Sensorineural hearing loss is the most common type of permanent hearing loss.
We donât really know why migraines cause light sensitivity, but itâs clear nearly everyone with migraine will tell you that they have sensitivity to light during an attack and many patients with migraine will tell you that certain kinds of light can trigger an attack (particularly those found in big box stores such as Target and Walmart).
The scientists studied two groups of blind people with migraines. Patients in one group were totally blind because of eye diseases, unable to see images or sense light. People in a second group were legally blind, but were able to detect the presence of light.
