ABSTRACT: The use of behaviorally defined sleep and wake states for detecting or predicting abnormal development in high risk newborn infants is addressed. One case of a relatively low risk 32-week gestation infant is used to illustrate that immediate subjective impressions by a trained observer may reveal information useful to the medical staff without having to wait for the lengthy computer analyses usually performed with this assessment technique. A second case illustrates a situation in which sleep/wake assessment by a trained observer assisted the medical team in confirming their diagnosis of massive brain damage and loss of function in an anencephalic newborn. The use of sleep variables in evaluating other behavioral and medical conditions in the young infant is also discussed.
