When Zayan first told me that he has epilepsy, I didn’t believe him. “You mean seizures, right?” I was embarrassed at how much I didn’t know.

Epilepsy is a disorder of the brain that triggers recurrent seizures. It can be caused by different conditions that affect a person’s brain. A person is diagnosed with epilepsy when they have had two or more seizures that are not caused by another medical condition such as a high fever or low blood sugar.

Zayan was thirteen years old when he had his first seizure in his school computer lab in Dhaka, Bangladesh. “The moments leading up to my seizure are hazy, but when I woke up in the hospital, my mind was wiped clean. I didn’t recognize my own father, whose tear-strewn face was fixated on mine. I couldn’t even remember how to talk.”

Following the incident, Zayan took a long break from school to seek medical care. He was diagnosed with idiopathic epilepsy, which is caused by an unknown factor that may be genetic. Epilepsy can be caused by different conditions, including stroke, brain tumor, brain infection, or traumatic brain injury. Zayan is one of the 60% of people where the cause of epilepsy is unknown.
