Insights
Children born extremely preterm show deficits in neuropsychological functions, including graphical skills, auditory perception, attention, and cognitive flexibility, compared to full-term peers. These developmental differences persist into school age, impacting overall cognitive performance.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatrics
Background:
- Extremely preterm infants often exhibit developmental challenges in school-age years compared to full-term children.
- Neuropsychological functions are critical for academic and social success.
Purpose of the Study:
- To compare the neuropsychological functions of schoolchildren born extremely preterm with those of full-term children.
- Identify specific areas of cognitive difference between the two groups.
Main Methods:
- Cross-sectional study involving 43 extremely preterm children (born <1500g and/or <32 weeks gestation) and 40 full-term controls.
- Utilized the Child Neuropsychological Assessment-ENI2, evaluating 14 cognitive domains.
- Kruskal-Wallis test used for data analysis with p < 0.05 significance.
Main Results:
- Children born extremely preterm generally scored lower, with significant differences observed in graphical skills, auditory perception, auditory attention, and cognitive flexibility.
- Performance varied, with some high and some low scores across different cognitive domains for both groups.
- Findings align with existing literature on developmental challenges in extremely preterm populations.
Conclusions:
- Extremely preterm children demonstrate a range of neuropsychological deficits.
- Cognitive performance in both extremely preterm and full-term children can be 'disharmonic,' with uneven strengths and weaknesses.
- Early identification and support for specific cognitive functions are crucial for extremely preterm individuals.
Introduction:
Monitoring of extremely preterm infants of school age reveals poor development of neuropsychological functions, compared to their full term peers.
Objective:
To compare the neurop sychological functions of schoolchildren with history of extreme prematurity and full term children of the same age.
Patients And Method:
Non-experimental, cross-sectional research. Forty-three pre term children who born weighting less than 1,500 g and/or less than 32 weeks of gestational age and a control group made up of forty full-term children, classmates of the sample group were included. Both groups had no diagnosis of neurological, sensory or cognitive disability. Parents signed infor med consent forms and data were collected through the Child Neuropsychological Assessment-ENI2, which considers 14 items: construction skills, memory, Perceptual skills, language, metalinguistic skills, reading, writing, arithmetic, skills spatial, attention, conceptual skills, fluency, cognitive flexi bility and planning. Data obtained were analyzed with Kruskal-Wallis test, establishing significance level at p < 05.
Results:
Research findings partially agree with problems reported in the literature. In general, a lower standard score was observed at lower gestational age. There were significant differen ces in subtests of graphical skills, auditory perception, auditory attention, and cognitive flexibility.
Conclusions:
Children with history of extreme prematurity who participated in this research showed a variety of deficits in neuropsychological functions, although their performance, as well as that of the control group, is disharmonic, with high scores in some items and low ones in others.
