Abstract

Sudden infant death syndrome (SIDS)—the sudden and unexplained death of a seemingly healthy infant, <1 year old—may be associated with abnormalities in the brain regions that underlie breathing and arousal during sleep. While post-mortem studies suggest abnormalities in SIDS infants' brainstems, there are no studies of these infants' brainstem function before death. One way to assess the function of the brainstem is with auditory brainstem response (ABR), a routine hearing-screening method that noninvasively measures the brainstem's response to sound. We hypothesize that anomalies in newborns' ABR measures may predict SIDS. Indeed, previous studies identified abnormalities in ABR characteristics in small samples of near-miss SIDS infants hospitalized for infant apnea syndrome. However, there is a need to examine the ABRs of infants who died of SIDS. Therefore, in the current study, we propose integrating two secondary datasets to examine newborns' ABRs (N = 156,972), including those who later died of SIDS (n = ~42; .27 out of every 1000 infants), using existing archived records of neonatal ABR results from a sample of newborns born in Florida. We hypothesize that infants who die from SIDS are more likely than non-SIDS infants to have abnormal ABRs as newborns. Understanding the association between SIDS and ABR may facilitate more accurate identification of an infant's risk for SIDS at birth, enabling increased monitoring, which may facilitate interventions and improve survivorship.

期刊介绍: The Journal of Neuroscience Research (JNR) publishes novel research results that will advance our understanding of the development, function and pathophysiology of the nervous system, using molecular, cellular, systems, and translational approaches. JNR covers both basic research and clinical aspects of neurology, neuropathology, psychiatry or psychology. The journal focuses on uncovering the intricacies of brain structure and function. Research published in JNR covers all species from invertebrates to humans, and the reports inform the readers about the function and organization of the nervous system, with emphasis on how disease modifies the function and organization.
