The early literature suggests that hypoventilation in infants with congenital central hypoventilation syndrome (CHS) is less severe during rapid eye movement (REM) than during non-REM (NREM) sleep. However, this supposition has not been rigorously tested, and subjects older than infancy have not been studied. Given the differences in anatomy, physiology, and REM sleep distribution between infan...

Congenital central hypoventilation syndrome with Hirschsprung's disease, also known as Haddad syndrome, is a rare disorder with a variable phenotypic severity. The underlying cause is thought to be an abnormality of neural crest development and/or migration. Surviving neonates can have generalized autonomic nervous system dysfunction. Recent reports have identified mutations in the PHOX2B gene ...

The concept of central sleep apnoea or hypoventilation encompasses hypercapnic central hypoventilation, such as obesity hypoventilation syndrome and eucapnic or hypocapnic central sleep apnoea. Among subjects with eucapnic or hypocapnic central sleep apnoea, several therapeutic options are available for those with Cheyne–Stokes respiration (CSR). CSR is frequent in patients with New York Heart ...
