Migraines and synaesthesia

In this study, Paul Hibbard and I were looking at the immune hypothesis of synaesthesia, which says that the harmless neurological condition of synaesthesia is linked to immune-related conditions like irritable bowel syndrome and multiple sclerosis. Since migraine is also linked to the immune system, we were interested in finding out whether synaesthetes were more likely to have migraines than other people. The answer is probably no (at least in women - we unfortunately weren't able to get enough men to take part to do the stats for them we needed to), but maybe some specific types of synaesthesia are linked to migraines.
