Patients with migraine (defined as individuals who meet the IHS criteria for migraine) are commonly intolerant of higher levels sensory inputs, and report pain from intensity of input that normal subjects find "under the radar screen" (Aurora and Wilkinson, 2007). The dislike for these stimuli are often called "phobias" for fear of the sensory input, as shown below. They are distinct from having lower thresholds (meaning ability to detect smaller levels of the input).
While those with extreme sensory intolerances are generally considered just idiosyncratic migraines, one might also reasonably argue that these groups could be considered as separate subvariants of migraine (such as hemiplegic migraine), or perhaps they are just genetic variants that are grouped into the rather broadly drawn and inclusionary criteria for "migraine". If so, they might actually reflect a different biochemical and neurological wiring arrangement. In other words, perhaps we are dealing with a lot of different diseases, put by the lumpers of the International Headache Society into one big pot called migraine. This is a problem with "committee illnesses", such as migraine and psychiatric disorders.
At least some of these patients are "hard wired" for enhanced sensation as some authors report larger volumes of sensory brain tissue (e.g. Kim et al, 2014).
