  • Title: Nocturnal sleep organization in infants "at risk" for sudden infant death syndrome.
    Author: Navelet Y, Payan C, Guilhaume A, Benoit O.
    Journal: Pediatr Res; 1984 Jul; 18(7):654-7. PubMed ID: 6472936.
    Abstract:
    Nocturnal sleep organization was compared in normal infants and those "at risk" for sudden infant death syndrome (SIDS) (siblings and near-miss infants). Before 12 weeks of age, sleep modifications were observed in "at risk" infants. During their sleep they had a smaller percentage of intervening wakefulness with a higher amount of active sleep. Quiet and active sleep episodes had longer durations resulting in a longer sleep cycle. After 12 weeks, sleep organization tended to normalize. This fact is discussed as a possible factor for a SIDS event: a higher arousal threshold could play a critical role if homeostasy is disturbed during sleep, mainly at an age when the homeostatic control is not fully established.
