“…However, perinatal variables associated to prematurity could have influenced the maturation of the central auditory pathway as previously reported (Stipdonk et al, 2016). Finally, in the current study we did not consider the possible influence of gray matter maturation on auditory processes' development, which is known to show rapid growth during the first postnatal year (Gilmore et al, 2012) coinciding with a rapid postnatal development of dendritic trees, dendritic branching, spines and synapsis (Elston & Fujita, 2014).…”

Assessing language development in the first postnatal year is difficult, as receptive and expressive skills are rudimentary. Although outward manifestations of change are limited, the auditory language system is thought to undergo critical development at this age, as the foundations are laid for the rapid onset of spoken language in the second and third years. We recruited 11 infants, 7 healthy controls (gestational age = 40.69 ± 0.56; range from 40 to 41.43) and preterm babies (gestational age = 28.04 ± 0.95; range from 27.43 to 29.43) who underwent a Magnetic Resonance Imaging study during the first postnatal year (age at scan = 194.18 ± 97.98). We assessed white matter tracts using diffusion-weighted magnetic resonance imaging with probabilistic tractography. Fractional anisotropy was found to be largely mature even at one month, although there was a little further increase during the first postnatal year in both the acoustic radiation and the direct brainstem-Heschl's pathway.

“…Auditory enrichment facilitates the development of the auditory cortex and stimulates the progression of neural arborisation and synaptogenesis [2,3]. Evidence from several studies demonstrates that the preterm infant's ability to process cortical signals is a significant factor affecting the development of receptive and expressive language skills [4,5,50]. Notably, auditory learning skills improve with increasing gestational age [2].…”

“…However, for infants born preterm (especially < 28 weeks) this development occurs in the abnormal environment of the neonatal unit, during a critical period of neural arborisation and synaptogenesis [3]. Significant delays have been found in auditory brainstem responses of preterm infants at a term-equivalent age, reflecting atypical brainstem maturation [4]. This is apparent even in preterm infants with normal brain ultrasound scans [5], which is believed to be attributable to exposure to the extrauterine environment [4].…”

Background: Elevated sound levels and low language exposures of preterm infants (< 37 weeks) cared for in the neonatal unit contribute to poorer growth, cognition, language and motor outcomes. These delays can have lasting effects on childhood development and continue throughout adult life. Whilst recommendations have been established for appropriate sound exposure levels in neonatal units, very little is known about the optimal level of language exposure. Objectives: To examine the evidence regarding language exposure, both measured (observational) and prescribed (interventional), in preterm infants (< 37 weeks) cared for in neonatal units and to identify optimal exposure levels to promote neurodevelopment. Search Methods: An electronic search of English-language articles with an open date range was conducted in the PubMed, MEDLINE, Joanna Briggs, CINAHL and Cochrane databases and in Google Scholar. The criteria were limited to original research studies of preterm infants (< 37 weeks) in which language was either measured as it naturally occurred in the neonatal unit environment or through a language intervention. Results: The search produced a total of 2,367 articles, 49 of which were related to language. A full-text review of these articles identified 10 eligible studies and 6 studies from reference searches. Conclusions: Preterm infants experience low levels of language exposure and high sound exposures in neonatal units. There is a lack of conclusive evidence to recommend an optimal level of language exposure to support improved neurodevelopmental outcomes in preterm infants. Further research from large, good-quality clinical trials is required before clear direction can be provided to inform clinical practice.

“…Fifth, our moderator analyses do not represent the full complement of factors that may affect the association between ASD and ABRs. For example, preterm delivery is associated with longer ABR latencies relative to full-term counterparts who are matched according to either chronological or corrected age [Jiang & Li, 2015;Stipdonk, Weisglas-Kuperus et al, 2016] and preterm delivery is a welldescribed risk factor for ASD. However, only three studies here reported specific information regarding perinatal health; one excluded preterm children [Roth, Muchnik et al, 2012], one included preterm children [Miron, Roth et al, 2016], and one excluded children with "infective prenatal conditions" [Tas, Yagiz et al, 2007].…”

Click‐evoked auditory brainstem responses and autism spectrum disorder: A meta‐analytic review

2018

Auditory brainstem responses (ABR) may be associated with ASD, but participant characteristics and assessment protocols vary considerably across individual studies. Our goal is to combine the results across these studies to facilitate clarity on the topic. Doing so represents a first step in evaluating whether ABRs yield potential for informing the etiology of ASD risk and/or ASD symptom profiles.
