Insights
Infants with subtle neuromotor issues, like low muscle tone, show increased risks for language delays and cognitive deficits. This finding extends to the general population, highlighting early development's importance.
Area of Science:
- Developmental Pediatrics
- Neuroscience
- Child Psychology
Background:
- Infant neuromotor development variations are linked to cognitive function in high-risk groups.
- The association in the general population and focus on subtle neuromotor signs remain less understood.
- Previous studies primarily examined motor milestone achievement.
Purpose of the Study:
- To investigate the association between infant neuromotor development and later cognitive and language functions in a general population cohort.
- To determine if subtle neuromotor variations, specifically low tone symptoms, predict language and nonverbal cognitive delays.
Main Methods:
- Utilized the Generation R Study, a population-based cohort in the Netherlands.
- Assessed infant neuromotor development at 12 weeks using an adapted Neurodevelopmental Examination.
- Measured language function at 1.5 years and language/nonverbal cognitive function at 2.5 years using validated checklists and surveys.
Main Results:
- Less optimal neuromotor development, characterized by more low tone symptoms, was associated with receptive language delay at 1.5 years (OR 1.18, 95% CI 1.05-1.34).
- Increased low tone symptoms correlated with expressive language delays across multiple time points (OR 1.11, 95% CI 1.02-1.21).
- Poorer overall neuromotor development predicted a higher risk of nonverbal cognitive delay at 2.5 years (OR 1.19, 95% CI 1.05-1.35).
Conclusions:
- Infants exhibiting more low tone symptoms, indicative of minor neuromotor deviations, demonstrate increased vulnerability to language delays.
- These findings suggest that subtle neuromotor variations in infancy can predict later language and cognitive challenges in the general population.
Objective:
Numerous studies in high-risk populations established that variations in infant neuromotor development predict poor cognitive function. It is unclear whether this association is found in the general population. Moreover, previous population-based studies mostly focused on motor milestone achievement.
Methods:
This study was embedded in the Generation R Study, a population-based cohort in Rotterdam, the Netherlands. Neuromotor development was assessed with an adapted version of Touwen's Neurodevelopmental Examination when infants (1205 males, 1278 females) were on average 12 weeks old (standard deviation 1, range, 9-15 weeks). To measure language function at age 1.5 years, the MacArthur Short Form Vocabulary Checklist was used. At 2.5 years, mothers completed the Language Development Survey and the Parent Report of Children's Abilities measuring language and nonverbal cognitive functioning, respectively.
Results:
After adjustment for confounders, less optimal neuromotor development, that is, more low tone symptoms, was associated with a delay in receptive language at 1.5 years (odds ratio [OR], 1.18; 95% confidence interval [CI], 1.05-1.34) and in expressive language at multiple time points (OR, 1.11; 95% CI, 1.02-1.21). Higher scores on overall neuromotor development, indicating a less optimal neuromotor development, was associated with an increased risk of a delay in nonverbal cognitive function at 2.5 years (OR, 1.19; 95% CI, 1.05-1.35).
Conclusions:
The results of this study suggest that infants with more low tone symptoms, indicating minor deviances from normal neuromotor development, are somewhat more vulnerable to language delays than those infants who do not have these symptoms.
