Insights
Mild traumatic brain injury (mTBI) in children can impair auditory processing, particularly temporal skills, even without cognitive deficits. Early identification of these auditory issues is crucial for effective intervention and support.
Area of Science:
- Neuroscience
- Audiology
- Pediatrics
Background:
- Mild traumatic brain injury (mTBI) can affect children's central auditory processing.
- Understanding the impact of mTBI on auditory and cognitive functions is essential for timely intervention.
Purpose of the Study:
- To investigate auditory and cognitive abilities in school-aged children post-mTBI.
- To examine children's and parents' perceptions of listening behaviors and symptoms after mTBI.
Main Methods:
- A prospective cohort study involving 21 children (8-12 years), including 11 with mTBI and 10 controls.
- Assessment included central auditory behavioral tests, cognitive screening, and questionnaires at acute (≤14 days) and chronic (≥3 months) stages.
- Statistical analyses included ANOVA and correlation.
Main Results:
- Children with mTBI showed poorer performance in auditory tests, specifically Pitch Pattern Sequence Tests (PPST), Gap In Noise (GIN) threshold, and Duration Pattern Test (DPT).
- No significant differences were found in cognitive abilities or perceived listening behaviors between groups.
- Correlations were observed between perceived listening behaviors and mTBI symptoms for both children and parents.
Conclusions:
- Auditory processing, especially temporal aspects, is affected by mTBI in children, independent of cognitive function.
- Improved identification of auditory processing difficulties post-mTBI can enhance treatment strategies and resource allocation for affected children.
Objective:
The current study aimed to explore (1) school-aged children's auditory and cognitive abilities and (2) their perceptions (self-reported and parents) of listening behaviours and symptoms following mild traumatic brain injury (mTBI).
Design:
Prospective cohort study.
Study Sample:
Twenty-one children aged 8 to 12 participated in this study. Eleven children with mTBI were diagnosed in the emergency department, and 10 were matched controls. They were assessed twice, in the acute (≤14 days) and chronic (≥3 months) stages post-injury, using six central auditory behavioural tests, a cognitive screening battery, and questionnaires. ANOVA and correlation analysis were performed.
Results:
Group differences were present in three auditory tests as children with mTBI obtained poorer scores than controls (Pitch Pattern Sequence Tests - PPST: p = 0.037; Gap In Noise test - GIN threshold: p = 0.046; Duration Pattern Test - DPT: p = 0.053), but not for perceived listening behaviours and cognitive abilities. Correlations were found only between perceived listening behaviours and reported mTBI symptoms for parents (p =0.014) and children (p =0.002).
Conclusions:
Auditory abilities, mostly those related to temporal processing, were affected following mTBI, independently of cognitive abilities. Better identification of auditory processing difficulties following mTBI will improve treatment and resource allocation for children.
