The Hogan twins have struggled to survive since they were conceived in the womb. Statistically, they had a 20% chance of being born alive. If they beat that hurdle then there was a 75% chance they’d die within 48 hours.
Today, they are three years old and they are very much alive.
The Hogan twins are incredibly unique. Not only are they conjoined at the head, but they also share parts of their brain. Most remarkably, Tatiana and Krista have the capability to use each other’s senses — they can even see out of one another’s eyes.
The new special, The Twins Who Share a Brain, follows one year in the lives of these two extraordinary sisters. It airs this Tuesday, June 15 at 9P et/pt on Nat Geo.
