Questions

Questions & answers

Who is behind Cerebral Torque?

Cerebral Torque is a migraine education platform run by a migraine researcher with a medical background. We read the peer-reviewed research, explain it in plain language and link to the studies we cite, so you can check them yourself.

Is your migraine education really free?

Yes, always. The Resource Hub, the MigraineScience blog, Today in Migraine Science and the specialist directory have no paywalls and no sign-up walls. Our book and products help pay for it.

Can you tell me which treatment is right for me?

No, and we won't try. We explain what the research says so you can have a better conversation with your own doctor. If you need a headache specialist, our free specialist directory can help you find one.

What is Unraveling Migraine?

Unraveling Migraine (2nd Edition) is our complete, evidence-based guide to migraine as a neurological disease: 821 pages and 98 chapters, fully illustrated with original figures, written to be clear enough for patients and deep enough for the physicians treating them. See what's inside.

CROWN or CROWN Plus, which one is for me?

Both work during migraine attacks. They use different coolants, so the cold feels different. CROWN is the everyday roller, for daily use and migraine attacks: menthol and camphor, with magnesium, Bing Pian, Chuan Xiong and German chamomile, so it isn't just about the cold. CROWN Plus is the maximum-cooling roller for migraine attacks: the Triple Cool Complex with Bing Pian, Chuan Xiong and Bai Zhi. Neither has lavender. See how they differ.

Where can I buy what you make?

Everything we make is sold through Amazon, so you get Amazon checkout, delivery and returns. We don't sell on this site. The book, CROWN and The Migraine Record are on Amazon now, and CROWN Plus is coming soon to Amazon.
