Identifying children and adolescents with cognitive dysfunction following mild traumatic brain injury—Preliminary findings on abbreviated neuropsychological testing

Abstract

Objective: Studies on cognitive function in paediatric patients suffering head trauma suggest neuropsychological impairment even after mild traumatic brain injury (MTBI). The present study examined the feasibility of abbreviated neuropsychological testing in different settings in children and adolescents following MTBI.

Methods: Within the scope of two prospective studies on psychosocial and cognitive outcome, 71 school-aged children with mild, moderate or severe TBI were assessed. In addition, 15 healthy children were included in the study. The abbreviated instrument comprises three standardized tests measuring attention and memory functions (Digit Symbol, Digit Span, learning trials of the German Auditory Verbal Learning Test). Impairment rates were calculated according to a defined cut-off score for clinically significant cognitive impairment.

Results: Abbreviated testing could easily be implemented both in the acute and post-acute clinical setting. Out of the children with MTBI, 12% (shortly after injury) and 30% (2 months after injury), respectively, were classified as cognitively impaired. Following moderate or severe TBI, impairment occurred in 50% of the patients. Healthy children showed the best performance, while children with severe TBI performed worst.

Conclusion: Results suggest that abbreviated testing allows detection of MTBI-related cognitive dysfunction. Identified children should be referred to a clinical neuropsychologist for comprehensive assessment.
