“…These results are in accordance with those obtained by Paluch et al in a study on three children using cochlear implants, who were implanted before the age of 2.5 years old. This group has shown that after nine months of using the cochlear implant, in the non-verbal cognitive domain, patients registered average or above-average scores [ 30 ]. It is important to notice that in our study, the average age for implantation was 22 months of age.…”

Background and objectives: The cochlear implant is not only meant to restore auditory function, but it also has a series of benefits on the psychomotor development and on the maturation of central auditory pathways. In this study, with the help of neuropsychological tests and cortical auditory potentials (CAEPs), we intend to identify a series of instruments that allow us to monitor children with a cochlear implant, and later on, to admit them into an individualized rehabilitation program. Materials and methods: This is a longitudinal study containing 17 subjects (6 boys and 11 girls) diagnosed with congenital sensorineural hearing loss. The average age for cochlear implantation in our cohort is 22 months old. Each child was tested before the cochlear implantation, tested again 3 months after the implant, and then 6 months after the implant. To test the general development, we used the Denver Developmental Screening Test (DDST II). CAEPs were recorded to assess the maturation of central auditory pathways. Results: The results showed there was progress in both general development and language development, with a significant statistical difference between the overall DQ (developmental quotient) and language DQ before the cochlear implantation and three and six months later, respectively. Similarly, CAEP measurements revealed a decrease of positive-going component (P1) latency after cochlear implantation. Conclusion: CAEPs and neuropsychological tests prove to be useful instruments for monitoring the progress in patients with cochlear implants during the rehabilitation process.

“…The DSR is a collection of tests that analyse the behaviour and motor skills of children between 2-36 months [64]. This can be divided into two main scales, the Performance and Observational Scales, which each consist of 10 and four subscales, respectively [60].…”

Breast Milk Micronutrients and Infant Neurodevelopmental Outcomes: A Systematic Review

2021

View full text Add to dashboard Cite

Micronutrients are fundamental for healthy brain development and deficiencies during early development can have a severe and lasting impact on cognitive outcomes. Evidence indicates that undernourished lactating individuals may produce breast milk containing lower concentrations of certain vitamins and minerals. Exclusively breastfed infants born to mothers deficient in micronutrients may therefore be at risk of micronutrient deficiencies, with potential implications for neurodevelopment. This systematic review aims to consider current knowledge on the effects of breast milk micronutrients on the developmental outcomes of infants. The databases Medline, Global Health, PsychInfo, Open Grey, and the Web of Science were searched for papers published before February 2021. Studies were included if they measured micronutrients in breast milk and their association with the neurodevelopmental outcomes of exclusively breastfed infants. Also, randomised control trials investigating neurocognitive outcomes following maternal supplementation during lactation were sought. From 5477 initial results, three observational studies were eligible for inclusion. These investigated associations between breast milk levels of vitamin B6, carotenoids, or selenium and infant development. Results presented suggest that pyroxidal, β-carotene, and lycopene are associated with infant neurodevelopmental outcomes. Limited eligible literature and heterogeneity between included papers prevented quantitative synthesis. Insufficient evidence was identified, precluding any conclusions on the relationship between breast milk micronutrients and infant developmental outcomes. Further, the evidence available was limited by a high risk of bias. This highlights the need for further research in this area to understand the long-term influence of micronutrients in breast milk, the role of other breast milk micronutrients in infant neurodevelopmental outcomes, and the impact of possible lactational interventions.

“…Examples include studies of the effects of unilateral hearing loss (e.g. altered response lateralisation) [41,42] or development of cortex in congenitally deaf children fitted with cochlear implants [43,44]. Higher cognitive functions can also be studied with appropriate ERP/ ERF experimental protocols.…”

In this review we describe several methods that can be used to study auditory processing in the cerebral cortex, including functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), electroencephalography (EEG), functional near-infrared spectroscopy (fNIRS), and positron emission tomography (PET). We explain the principles of each technique and list the characteristics that make them suitable for certain research applications. For each method we give a broad range of examples that have already helped uncover various aspects of cortical auditory processing. We compare and summarise the characteristics of each method in order to help the reader choose one that is best suited to answer a specific research question. We also give perspectives on multimodal imaging -collecting functional brain data with two or more techniques during one study -as a means for overcoming the limitations of each method alone by examining complementary information. This article aims to be a short introductory guide and source of reference for researchers in the field of auditory neuroimaging.
