May flag SIDS-related brainstem pathology via early autonomic testing; hypothesis-generating and requires prospective validation before any clinical use.
Case Report (n=1)
This case report suggests that medullary 5-HT system abnormalities associated with SIDS risk may be identifiable prior to death via physiological tests such as heart rate variability.
Kinney et al. (2005) conducted a case report in Sudden infant death syndrome (SIDS) (n=1). Medullary 5-HT system abnormalities was evaluated on Cardiorespiratory assessment of heart rate variability and autopsy findings. Medullary 5-HT system abnormalities and arcuate nucleus hypoplasia at autopsy correlated with subtle autonomic dysfunction measured prospectively on postnatal day 2 in an infant who died of SIDS.
