“…AEPs have been applied widely to the examination of the integrity of brainstem nuclei and peripheral auditory pathways. 8 Conduction through the neural pathways has also been seen to be affected by nutritional status as shown by Soury et al 9 The present study observed prolongation of Wave I, II, III, IV, and Prolonged inter-peak latency I-III, I-V with P<0.05 in the SAM group. This may be due to imperfect growth and development of myelin-producing initial abnormalities in an increase in interpeak latency particularly I-III.…”

Background: Malnutrition is a public health concern in India. According to NFHS-5, the number of children under 5 years who are stunted (less height-for-age) and underweight (less weight-for-age) in India, are 35.5% and 32.1%, respectively. Many researchers reported that malnutrition affects myelination and neural maturation of the auditory brainstem pathway. Aims and Objectives: In this study, auditory evoked potential (AEP) parameters were studied in severly acute malnutrition (SAM) children of 6 months to <5 years of age. Materials and Methods: Fifty children, with severely malnourished (Their weighted age was 51–60% of the expected weight, and height for age <85% of the expected height) and 50 healthy children (with weight >80% of expected with normal height for their age), aged 6–59 months were included in the study. The parameters of AEPs were recorded using RMS-EMG EP MARK II, a 4-channel machine. Results: In our study, 30 (60%) males and 20 (40%) females had severe acute malnutrition. There were significant differences in the mean latencies of the waves I to V and the mean interpeak latencies (IPLs) of the waves I-III and I-V on the right and left ears between the study and control groups (P<0.05). The mean IPLs of I-III and I-V on the right side were found to be longer in the SAM group than in the control group (P<0.05. While the mean absolute peak latencies of wave, I found prolonged on both ears in the children with SAM (P<0.05). Conclusion: In the present study, severely acute malnourished children showed changes in AEPs characterized by absolute wave prolonged latencies and interpeak intervals compared with normally nourished children.

“…These changes could be attributed to myelination defects in the auditory pathway's neural tissue. Similarly, Zuanetti et al, and Vandana and Tandon 8,10 revealed that conduction through the neural pathways has also been seen to be affected by nutritional status.…”

“…The studies in the literature regarding risk factors for language and/or arithmetic skills have mostly analyzed one variable at a time, e.g. studies on prematurity, 9 , 10 severe malnutrition in the first years of life 11 or resources present at home, 12 , 13 among others. However, few studies have analyzed which variables out of these many factors are the most likely to impair linguistic and mathematical development.…”

Language is a complex cognitive function, characterized by a system of principles and rules that enable people to code their meaning in a symbol, and vice-versa. 1 It has both expressive and receptive components. 1 Under a natural course, oral language skills are developed first (pragmatic, phonological, morphosyntactic and semantic aspects), and then metalinguistic and written language skills are acquired. Arithmetic skills, in turn, are related to numerical properties and operations. 1 To develop arithmetic skills, three different systems are recruited, depending on the task: a nonverbal system (responsible for presenting the relationship between numbers); a verbal system (the numbers are expressed as a type of word); and a visual system (numbers can be decoded as Arabic numerals). 2 Development of the abovementioned cognitive skills is of utmost importance to the life of every human being within literate society. 3 For these skills to be adequately developed, children need to be integrated into various environments, and to acquire other levels of development. Recent reports have shown prevalences of alterations in written language and/or arithmetic performance of approximately 22% among Indian schoolchildren 4 and 54% among Brazilian schoolchildren. 5 Regarding the prevalence of specific learning disorders (dyslexia and/or dyscalculia), the same studies stated that the percentage was 3% in Brazil, 5 9% in Turkish-born children 6 and 7.5% in India 4. They also showed that high rates of comorbidities were present in children with
