Did you know that CCHS was briefly known by another name? What we now know as Congenital Central Hypoventilation Syndrome (CCHS) was first reported in a newborn in 1970 and was originally called "primary alveolar hypoventilation" or "Ondine’s curse”. The condition was later named CCHS in 1978, reflecting its cause, an abnormality in the brain's automatic control of breathing, not linked to lung, heart, muscle, or structural neurologic disease.
