About this episode

This episode explores the complexities of migraines, their causes, and the differences in prevalence between genders.

Migraines are not “just headaches”! In this episode, Dr Amir Khan and Cherry Healey look at what’s really happening inside your brain during a migraine, from the trigeminal nerve to the brain chemical CGRP that can trigger intense pain, nausea, and visual disturbances. Find out why women are three times more likely to experience migraines than men. What role hormones and oestrogen play, especially around your period and during perimenopause. And when does a migraine become something more serious, like a “thunderclap headache” that needs urgent medical attention. We've partnered with ⁠Randox Health⁠.
