“…Amongst all aspects of poor outcome in preterm infants, language development is commonly impaired (2). Previous studies indicated that infants with poor language performance at school age show abnormalities in electrocortical signals already in the neonatal period (3,6). Mehta et al showed that abnormalities in conventional EEG are present in 64.5% of infants with speech and language impairment (5).…”

“…Event-related potentials are small parts of continuous electroencephalography recordings, which are evoked in response to stimuli and have been shown to be valuable in studying language processing or development and to predict literacy precursor skills. Paquette et al reported that electrophysiological indicators, such as auditory event-related potentials and mismatch negativity, could be used in the neonatal period to predict atypical language processing later in life (3). So far, few studies investigated whether event-related potentials could be used to detect or predict cognitive impairments in preterm born infants and at present this method has not been applied in clinical practice in the neonatal period (6).…”

Aim To assess whether amplitude‐integrated electroencephalography (aEEG) alterations in the newborn period are associated with poor precursor skills of literacy at five years of age in children born preterm. Methods Between October 2007 and September 2011 248 preterm infants were eligible for the study at Innsbruck Medical University Hospital. aEEG was analysed for dominating background activity, calculation of the percentage of continuous activity, the Burdjalov scoring system, the minimum, mean and maximum amplitude. At the age of five years, we evaluated preterm born children by the Bielefelder screening (BISC) to assess for early diagnosis of reading problems and weak spelling and classified them as normal performers (n = 64) or poor performers (n = 20). Completion of testing was not possible for one infant. Results The minimum amplitude was significantly lower in the poor BISC performance group as compared to the normal BISC performance group at postnatal week two. The percentage of continuous background activity was significantly higher in infants with normal BISC performance than in infants with poor BISC performance at postnatal week three. Conclusion Children with poor developed precursor skills of literacy showed alterations in aEEG signals. The aEEG could be useful in further diagnosing preterm infants at risk for developmental complications.

“…The difference of neurological development between preterm and full-term infants can be assessed in an objective way and at an early age by means of brain magnetic resonance imaging, in which different patterns of brain activity are observed, showing delayed maturation of several brain regions (15) , and the assessment of brainstem auditory evoked potentials (16,17) , which are considered early physiological markers, indicating which children may have language development disorders in the future (16) . Behavioral tests / scales are also widely used to assess and monitor the neuropsychomotor and linguistic development of preterm infants in tertiary referral hospitals, enabling early detection of changes.…”

Introduction: This study relates prematurity to linguistic impairments. Purpose: To analyze several variables related to prematurity, identifying the risk factors for language development disorders. Methods: Medical records of 98 preterm-born children (1 to 6 years) were analyzed. Data on language development (DENVER II test) and several variables, such as gestational age, length of hospital stay and postnatal complications were collected. From the Denver II test results, the sample was divided into two groups: G1: 28 children with risk factors for linguistic impairment; G2: 70 children without risk factors for linguistic impairment. Regression models and Fisher test (α=0,05) were used for statistical inferences. Results: The presence of peri-intraventricular hemorrhage (PIVH) or bronchopulmonary dysplasia (BPD), maternal age less than 18 years, birth weight less than 1000g and long hospital stay were identified as risk factors for language development. There was also an association between risk for language disorders and the presence of risk in motor and social areas. Conclusion: Prematurity itself cannot be assigned as a risk factor for language development. In such cases, the variables associated with prematurity must be further assessed, limiting the involved risk factors. In this study, the presence of PIVH, BPD, maternal age less than 18 years, birth weight less than 1000 grams and long hospital stay were identified as risk factors for language development.

“…Additionally, to further understand the origin of reading difficulties in children born preterm and their neural basis, the results should be interpreted in light of studies reporting delayed event‐related potentials and mismatch negativity responses to speech sounds in 3‐month old children born preterm. It has been suggested that these measures can be used for the early identification of the risk of language impairment …”

“…It has been suggested that these measures can be used for the early identification of the risk of language impairment. 3 One strength of this study is that both fractional anisotropy and mean diffusivity results are reported. These measures are related but different, and so reporting both gives a fuller picture of the neural bases underlying pre-reading skills.…”
