Life was proceeding right on schedule for self-described “drama kid” Genevieve Masson. The 16-year-old, who goes by “Geni,” went to class, hung out with friends and spent time rehearsing musical theater at her high school.

But two years ago, when Geni was 14, something changed. A small lesion that had been in her brain since birth began making itself known. One night, she woke up and couldn’t move. She figured she was caught in a moment of sleep paralysis and didn’t give it too much thought.

Things quickly turned far more serious. A few days later, Geni was feeling tired at school and decided to take a nap in her coach’s office. That’s when she had her first full-on seizure.

Geni has no memory of what happened next, but those around her became alarmed as her body shook uncontrollably. A teacher called 911 and the next thing Geni knew, she was in an emergency room.

An MRI revealed nothing, as did visits to pediatricians. But not only did the seizures continue, they were occurring more often. The more severe ones occurred at night, while less noticeable ones were happening many times a day. Ultimately, she was diagnosed with epilepsy, but she wasn’t receiving the expert care she needed at nearby hospitals.

“I remember the day she had her first seizure. It was December 18,” says Susan Masson, Geni’s mom. “By that January, there were a couple more. It got to be about 15 to 20 a day. We knew we needed to be at CHOC. We needed to be at a place where we could be with an epileptologist.”
