Abstract
Objectives Traumatic brain injury (TBI) is associated with deficits in cognition, language, and communication along with physical and psychosocial consequences. This study aimed at evaluating the association between cognition, language, and communication in a cohort of patients with TBI in southern India using standardized language specific assessment tools. Materials and Methods The present correlational study included 30 patients with TBI of any severity, that is, mild, moderate, and severe within the postinjury period of 6 to 36 months. Comprehensive evaluation of cognition, language, and communication was done using National Institute of Mental Health and Neurosciences Neuropsychology Battery, Indian adapted versions of Western Aphasia Battery and La Trobe Communication Questionnaire (LCQ) respectively. Data Analysis Measures of descriptive statistics, that is, mean, median, percentages, and frequencies, were used. Raw scores, that is, aphasia quotient (AQ), and subdomain scores for LCQ, that is, LCQ-quality, quantity, relation, manner, and cognition, were calculated. Composite scores for the three neuropsychological domains, that is, attention and processing speed, executive function, learning and memory, were evaluated. Partial correlation was computed for identifying the association between the three variables by controlling for age, education, duration, and severity of injury. Results A significant correlation was found between AQ and measures of attention and executive functioning and all measures of LCQ except LCQ-manner. Further, a significant correlation was found between executive functioning and LCQ-total, LCQ-quantity, and LCQ cognition. No correlation was found between measures of attention and memory with communication. Conclusion A good language and executive functioning are associated with better communication abilities in patients with TBI thus emphasizing on the importance of a multidisciplinary team for the management of cognitive-communication impairments following a TBI.
