Traumatic Brain Injury and Pediatric Working Memory
Traumatic brain injury (TBI) during childhood can have long-term effects on cognitive and psychosocial functioning, including poor academic achievement. Pediatric TBI can cause significant deficits in working memory, as demonstrated in a study published in Journal of Neurotrauma, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available on the Journal of Neurotrauma website.
Working memory is the ability to collect, retain, and use information needed to perform tasks and respond to immediate demands. Amery Treble and coauthors from University of Houston, Texas and University of Texas Health Science Center at Houston used brain imaging studies to measure verbal and visuospatial working memory in a group of children who sustained TBI and a control group who did not. The comparison showed poorer visuospatial working memory in the pediatric TBI group, which was associated with disruptions in brain connectivity between neural networks that underlie working memory.
