The Clinical Syndrome of Bilirubin-Induced Neurologic Dysfunction

We believe that the syndrome of bilirubin-induced neurologic dysfunction [BIND] represents a spectrum of neurologic manifestations among vulnerable infants who have experienced an exposure to bilirubin of lesser degree than generally described in previous publications. Clinical neuro-motor manifestations extend to a range of subtle processing disorders with objective disturbances of visual-motor, auditory, speech, cognition, and language among infants with a previous history of moderate-to-severe hyperbilirubinemia of varied duration. Confounding effects include prematurity, hemolysis, perinatal-neonatal complications, altered bilirubin-albumin binding, severity and duration of bilirubin exposure, and the individual vulnerability of the infant related to genetic, family, social, and educational predilection, regardless of the cause of neonatal jaundice. Tools to better assess BIND specific domains of multisensory processing disorders, identified by pyschometric, audiologic, speech, language and visual-motor, and neuromotor examination would allow for prospective surveillance of infants at risk for the syndrome.
