Scents, Chemicals & the Migraine Brain
Key Questions
- What are volatile organic compounds (VOCs), and how do they relate to odors and the trigeminal nerve system in people with migraine disease?
- Do VOCs need to have an odor to be a trigger or cause problems for people with migraine disease?
- What steps can be taken to mitigate the high concentration of VOCs and chemical compounds released from new items like furniture or flooring?
- How does osmophobia (smell sensitivity) during an attack differ from an odor acting as a direct migraine trigger?
- What were the unexpected research findings regarding olfactory function in people with migraine disease and osmophobia?
- What strategy is advised to help people with migraine disease avoid losing their ability to smell while still managing potentially triggering odors?
- Do studies show that having migraine with aura affects sensitivity to smells differently than having migraine without aura?
- What types of protections or accommodations could be sought in the workplace for people who are highly sensitive to VOCs and chemical smells?

Migraine doesn't have to derail your career. Nearly every workplace in the country is impacted by migraine disease through absenteeism and presenteeism. Despite the prevalence of the disease, there is a lack of education and awareness around it. In the workplace, this often leads to unintended stigma and bias against employees living with migraine disease.
