The relationship between brain volume loss in TBI and measures of cognition and narrative discourse

Abstract

The present study of 167 individuals with TBI investigated how well total brain volume loss accounts for performance on cognitive tasks, including WM, immediate memory (IM), EF, and IQ, and on narrative discourse production measures at multiple levels (e.g., intra-sentential, inter-sentential, global) of analysis. An underlying goal of this study was to examine the prognostic potential of a brain lesion metric for outcomes in discourse production. It is hypothesized that brain volume loss will correlate significantly with the cognitive and narrative discourse measures
