Insights
Corrected age is crucial for assessing premature newborn infant (PNI) development. While perceptive and language skills align with corrected age, static balance may deviate, highlighting the need for early intervention.
Area of Science:
- Developmental Pediatrics
- Neuroscience
- Neonatology
Context:
- Neurological evaluation requires age-specific criteria across developmental stages, from premature newborn infants (PNI) to teenagers.
- Corrected age is vital for accurately assessing psychomotor development in premature infants.
- This study monitored a cohort of PNIs from birth to 12 months corrected age, focusing on motricity, sociability, and speech.
Purpose:
- To establish developmental milestones for premature newborn infants (PNIs) at corrected ages of 3, 6, 9, and 12 months.
- To identify potential deviations in motor, perceptive, and language development in PNIs.
- To underscore the importance of early diagnosis and intervention for developmental disorders.
Summary:
- Neurological development frameworks were established for PNIs at corrected ages of 3, 6, 9, and 12 months.
- Perceptive and language functions showed uniform development according to corrected age.
- Static balance was the sole motor aspect not aligning with expected corrected age milestones.
Impact:
- Reinforces the critical window for early diagnosis of developmental disorders in the first year of life.
- Highlights the optimal period for initiating psychomotor and affective stimulation due to brain plasticity.
- Provides essential data for understanding and supporting PNI neurodevelopmental trajectories.
Introduction:
It is necessary to differentiate neurological evaluation in the different stages of development, which include the premature newborn infant (PNI), the full term newborn, the unweaned baby, the child and the teenager. Several studies have shown the importance of using the corrected age when exploring the psychomotor development of premature babies.
Casuistics And Method:
The population we studied was made up of a cohort of PNI who were born in the Hospital de Cl nicas de Porto Alegre and were monitored until they reached the age of 12 months. Motricity, sociability and speech were all considered.
Results And Conclusions:
It was possible to establish the frameworks of neurological development at the corrected ages of 3, 6, 9 and 12 months. The development of static balance was the only item among the motor aspects that did not agree with what was to be expected for the corrected age. The PNIs development was uniform, with regard to the perceptive and language functions for each corrected age. Such results reinforce the importance of studies like the one we present in this paper, since it is a period that can provide us with information that is useful for the early diagnosis of development disorders. It is also the best time to indicate psychomotor and affective stimulation, if we bear in mind the importance of the brain s plasticity during the first year of life.
