Hannah is a second-year medical student who faces her own medical mystery. A few years ago, she started having uncontrollable and unexpected convulsions which, to most people with any experience of it, appeared to be epileptic seizures. But doctors say she doesn't fit the criteria to be someone affected by epilepsy.

With a definitive diagnosis, Hannah can't take medication, so her condition can't be controlled. The constant uncertainty that she could have another episode at any time is having a profound effect on her life.

This episode is the story of how Hannah and her mother Jenni (from episode 10) are determined to work out what is causing Hannah's condition and how the uncertainty is affecting their lives.

Most people don't like to talk about epilepsy, but about one in five of us are affected by it, directly or indirectly. Despite this, there is still a seemingly immoveable stigma surrounding the condition.

Epilepsy is far more than just seizures, and we hope these stories will give you an insight into this.

Epilepsy is a common brain condition that takes the form of recurring seizures. It can develop at any age, regardless of ethnicity or gender.
