The Hadley Family
Peyton is the oldest of the three Hadley children. Peyton began to show symptoms of NPC when he was eight, and a year and a half later he was officially diagnosed with Niemann-Pick Type C.
Kayla received her official NPC diagnosis at the same time as her big brother Peyton. Despite having an enlarged spleen as an infant, Kayla has since been completely asymptomatic with the help of cyclodextrin.
Niemann-Pick Type C
For many years, Bryan and Laura didn't know their kids had NPC, and doctors didn't test for it. One telltale symptom - an enlarged spleen - could have told them otherwise.
Dr. Caroline Hastings
After treatment, Peyton told his family and doctor that he could think more clearly and focus better.
