Conjoined Twins Who Share a Brain Are Now 19 and Thriving

Tatiana and Krista Hogan were born connected at the head, sharing not just a skull—but part of their brain. Doctors didn’t expect them to survive 24 hours. But nearly two decades later, the twin sisters from Canada are 19 and living a remarkable life.

Their condition, called craniopagus, is incredibly rare—occurring in only 1 in 2.5 million births. What makes their case even more unique is the thalamic bridge that connects their brains. It allows them to feel each other’s pain, taste what the other is eating, and even sense each other’s thoughts.

Despite this deep connection, they’re very different people. Tatiana is quiet and thoughtful, while Krista is outgoing and full of emotion. Together, they’ve learned to swim, ride a custom bicycle, and even run in sync—moving as one with incredible coordination.

Their journey hasn’t been easy. Some parents were uneasy when the girls started preschool, and their brain connection led to learning delays. But with the love and support of their family, Tatiana and Krista learned to read, write, and tackle basic math just like their peers.

Against all odds, they continue to beat expectations—living proof that love, resilience, and connection can defy even the rarest of challenges.
