“…While this is often reported as a response time difference between persons with TBI and control participants, it is not attributable to simple motor factors, as it can occur even when simple motor response times are statistically identical between TBI and control groups (Russell, Scanlon, Arenth, & Ricker, 2009). Speed of processing differences have been noted during verbal and visual fluency, verbal memory, serial addition, and many other tasks (e.g., Bittner & Crowe, 2007;Madigan, DeLuca, Diamond, Tramontano, & Averill, 2000;Mathias et al, 2004). It seems that tasks which are more cognitively "complex" or require interhemispheric transfer are most likely to elicit speed of processing difference effects.…”

“…Mahar and Fraser stated that "disruption of cognitive functioning is irrefutably the primary deficit following most forms of brain injury" [9, p. 54]. The cognitive skills that are affected due to TBI include attention, memory, processing speed, problem solving, judgment, executive functioning, self-awareness, numeracy and literacy ability, multitasking ability, and verbal learning and comprehension [9,[16][17][18]. A variety of cognitive intervention methods comprised of both restoring and compensating interventions were used to treat cognitive deficits in TBI [19].…”

Abstract. BACKGROUND:Approximately two percent of the United States population are traumatic brain injury (TBI) survivors. The unemployment rate among them is substantial. Cognitive skills are essential to perform any job. OBJECTIVE: We analyzed the literature on cognitive rehabilitation (CR) related to mild/moderate TBI to learn the influence of cognition on return to work (RTW) post TBI. METHODS:We conducted a systematic review of the studies on CR related to RTW post TBI that were published between 2000 and 2015. RESULTS: We critically reviewed 30 studies that met the inclusion criteria. Ten studies highlighted cognition as a predictor variable, seven studies demonstrated support for cognitive testing in RTW assessments, and 13 studies showed the efficacy of CR in facilitating RTW post TBI. CONCLUSION: Cognition plays a significant role in predicting and facilitating RTW in patients with TBI.

“…The PASAT activation task is conceptualized as multifactorial. It requires the successful completion of numerous cognitive functions, including executive control, numeric addition, attention, and working memory (19,20), which are expected to induce multiple areas of activation. Our results, showing activation in the dorsolateral prefrontal cortex, right and left superior temporal gyrus, right and left medial frontal cortex, and cerebellum in healthy control subjects, are consistent with the above hypothesis.…”

Differential SPECT Activation Patterns Associated with PASAT Performance May Indicate Frontocerebellar Functional Dissociation in Chronic Mild Traumatic Brain Injury

Patients with mild traumatic brain injury (TBI) often complain of cognitive fatigue during the chronic recovery phase. The Paced Auditory Serial Addition Test (PASAT) is a complex psychologic measure that may demonstrate subtle deficiencies in higher cognitive functions. The purpose of this study was to investigate the brain activation of regional cerebral blood flow (rCBF) with PASAT in patients with mild TBI to explore mechanisms for the cognitive fatigue. Methods: Two groups consisting of 15 patients with mild TBI and 15 healthy control subjects underwent 99m Tc-ethylene cysteine dimer SPECT at rest and during PASAT on a separate day. Cortical rCBF was extracted using a 3-dimensional stereotactic surface projection and statistically analyzed to identify areas of activation, which were compared with PASAT performance scores. Results: Image analysis demonstrated a difference in the pattern of activation between patients with mild TBI and healthy control subjects. Healthy control subjects activated the superior temporal cortex (Brodmann area [BA] 22) bilaterally, the precentral gyrus (BA 9) on the left, and the precentral gyrus (BA 6) and cerebellum bilaterally. Patients with mild TBI demonstrated a larger area of supratentorial activation (BAs 9, 10, 13, and 46) but a smaller area of activation in the cerebellum, indicating frontocerebellar dissociation. Conclusion: Patients with mild TBI and cognitive fatigue demonstrated a different pattern of activation during PASAT. Frontocerebellar dissociation may explain cognitive impairment and cognitive fatigue in the chronic recovery phase of mild traumatic brain injury.
