A Nebraska woman who was born without a brain just celebrated her 20th birthday — a milestone no doctor believed she would ever reach.

Alex Simpson of Omaha was born with hydranencephaly, a rare neurological condition in which most of the brain’s hemispheres are missing and replaced with fluid. Doctors told her parents, Shawn and Lorena Simpson, that their newborn daughter likely wouldn’t live past her fourth birthday. Two decades later, Alex is still here — smiling, reacting to her family’s voices, and continuing to defy every expectation.

“[Hydranencephaly] means that her brain is not there,” Shawn told KETV News in an interview about his daughter’s birthday. “Technically, she has about half the size of my pinky finger of her cerebellum in the back part of her brain, but that’s all that’s there.”

What makes Alex’s story remarkable isn’t just her survival — it’s the quiet, steadfast love that has sustained her family for twenty years. When asked what’s kept Alex alive, Shawn and Lorena didn’t hesitate. “Love,” they both said.

“You can see that when I went up there and talked to her a little bit ago,” Shawn said, describing how Alex follows him with her eyes. “She was looking for me.”

Hydranencephaly is extraordinarily rare, occurring in roughly one in 5,000 to one in 10,000 pregnancies, according to the Cleveland Clinic. For most children born with the condition, life expectancy is measured in weeks or months, not years. The survival of someone like Alex — who has lived for two full decades — is almost unheard of.

Shawn says faith has been central to their journey. “Twenty years ago, we were scared,” he said. “But faith, I think, is really what kept us alive.”

Lorena calls her daughter a fighter — one whose life has rewritten every assumption that came with her diagnosis. Alex cannot speak, but her family insists she communicates in her own way, sensing emotion and presence even in silence.

Her younger brother, SJ, who’s 14, said his sister’s condition has shaped who he is. “When people ask about my family, the first thing I start with is Alex — my disabled sister,” he told KETV. “Say somebody’s stressed around her — nothing will even happen — it could be completely silent, but Alex will know. She’ll feel something.”

In a world that often measures value by ability or achievement, the Simpsons’ story offers something quieter but no less profound: a reminder of what it means to keep showing up. For two decades, the family has built a life around a child who was never supposed to live one.
