Insights
Transient periventricular echodensities in preterm infants can affect general movement quality. Longitudinal assessment of these movements helps predict neurological outcomes and identify infants at risk.
Area of Science:
- Neonatal neurology
- Developmental pediatrics
- Neuroimaging
Background:
- Periventricular echodensities are a common finding in preterm infants.
- The quality of general movements is a sensitive indicator of early brain development.
- The relationship between transient echodensities and long-term neurological outcomes requires further elucidation.
Purpose of the Study:
- To investigate the impact of transient periventricular echodensities on the quality of general movements in preterm infants.
- To correlate the developmental course of general movement quality with neurological outcomes.
- To identify infants at risk for impaired neurological development based on movement assessment.
Main Methods:
- Sequential videotape recordings were used to assess the quality of general movements.
- Infants were categorized based on the presence, location, and duration of periventricular echodensities.
- Neurological outcomes were assessed and correlated with movement quality trajectories.
Main Results:
- Echodensities, particularly in the parieto-occipital region, adversely affected general movement quality.
- Echodensities persisting beyond 14 days were consistently associated with abnormal general movements.
- Normal neurological outcomes were observed in infants with normal or transiently abnormal general movements; persistent abnormalities predicted impaired outcomes.
Conclusions:
- Longitudinal assessment of general movement quality is valuable in preterm infants with transient echodensities.
- This assessment aids in determining the presence of transient or persistent brain dysfunction.
- It effectively identifies infants at risk for adverse neurological outcomes, guiding early intervention.
Abstract:
By means of sequential videotape recordings, the relevance of the quality of general movements for neurological outcome was determined in a group of 21 appropriate-for-gestational-age preterm infants with transient periventricular echodensities of variable localization and duration and in 6 infants without echodensities. Echodensities, especially in the parieto-occipital area, affected the quality of general movements. Echodensities persisting beyond 14d were associated with abnormal general movements; infants with echodensities up to 14 d had either normal or abnormal general movements. The developmental course of movement quality was correlated to neurological outcome (p < 0.005): normal outcomes were found in 11/12 infants with normal general movements throughout and in 9/11 infants with transient abnormal general movements; all 4 infants with persistent abnormal general movements had impaired outcomes. In infants with transient echodensities, longitudinal assessment of the quality of general movements helps to determine if there is brain dysfunction, either transient or persistent, and identifies infants at risk for impaired neurological outcomes.
