At least, according to a recent small Japanese study.
In their study researchers had a closer look at the relationship between multiple chemical sensitivities and migraine in 95 patients of a headache clinic.
They found that 20% of patients with migraine had multiple chemical sensitivities. These group of patients had also the following (hyper)sensitivities:
- light sensitivity (photophobia),
- sensitivity to smells (osmophobia),
- seeing bright spots or flashes of light (visual aura),
- tingling or a feeling of numbness in arm (sensory aura), and
- elevated sensitivity to pain and the sensation of touch (central sensitization).
Moreover, compared to those without sensitivities, the migraineurs with multiple chemical and other hypersensitivities had a higher chance of migraine-related disabilities in day-to-day life and serious mental illnesses.
