“…As the ROCFT-DR has been found to be more strongly associated with executive functions than ROCFT-C, the former measure was regarded as more inclusive and globally representative of TBI patients' functioning, and used as a covariate of interest to investigate how inter-hemispheric FC may correlate with neuropsychological measures. 56 Analysis of the relationship between FC and RCFTdelayed performance. FSL's flameo tool was used to perform an ordinary least square regression entering as a factor the demeaned z-scores for the ROCFT-DR. 52 The association between FC and performance of TBI participants in the ROCFT-DR was assessed by examining the correlation between normalized FIG.…”

Traumatic brain injury (TBI) often has long-term debilitating sequelae in cognitive and behavioral domains. Understanding how TBI impacts functional integrity of brain networks that underlie these domains is key to guiding future approaches to TBI rehabilitation. In the current study, we investigated the differences in inter-hemispheric functional connectivity (FC) of resting state networks (RSNs) between chronic mild-to-severe TBI patients and normal comparisons (NC), focusing on two externally oriented networks (i.e., the fronto-parietal network [FPN] and the executive control network [ECN]), one internally oriented network (i.e., the default mode network [DMN]), and one somato-motor network (SMN). Seed voxel correlation analysis revealed that TBI patients displayed significantly less FC between lateralized seeds and both homologous and non-homologous regions in the opposite hemisphere for externally oriented networks but not for DMN or SMN; conversely, TBI patients showed increased FC within regions of the DMN, especially precuneus and parahippocampal gyrus. Region of interest correlation analyses confirmed the presence of significantly higher interhemispheric FC in NC for the FPN ( p < 0.01), and ECN ( p < 0.05), but not for the DMN ( p > 0.05) or SMN ( p > 0.05). Further analysis revealed that performance on a neuropsychological test measuring organizational skills and visuo-spatial abilities administered to the TBI group, the Rey-Osterrieth Complex Figure Test, positively correlated with FC between the right FPN and homologous regions. Our findings suggest that distinct RSNs display specific patterns of aberrant FC following TBI; this represents a step forward in the search for biomarkers useful for early diagnosis and treatment of TBIrelated cognitive impairment.

“…Such an approach also provides information on patient functioning in a form that is more useful to the planning of rehabilitation. However this does not mean that the domains are necessarily independent of each other (Clune-Ryberg et al, 2011;Schwarz et al, 2009). For example, the executive domain includes organisational and planning processes, and impairment in these aspects of cognition would impact on an individual's ability to draw a geometric shape, hence impacting on visual-spatial construction which would, in turn, impact on performance on a measure of visual memory.…”

“…Approximately half of the sample was impaired on both the immediate and delayed trial. While visual memory has been assessed in other follow-up studies of adults with TBI (Ashton et al, 2005;Schwarz et al, 2009), these other studies were completed on samples that were in the early stages following injury. The prevalence of impairment found here suggests that assessment of visual memory should be included in long-term followup studies of TBI as approximately half the sample was still impaired at five years following injury.…”

“…Assessment of people with TBI has consistently found impairment in all aspects of attention (Kennedy, Clement, & Curtiss, 2003;Slovarp, Azuma, & LaPointe, 2012). Similarly impairment in most aspects of both verbal and visual memory functioning is also commonly reported following TBI (Vakil, 2005;Ashton, Donders, & Hoffman, 2005;Schwarz, Penna, & Novack, 2009). Impairment in the domain of visual perception is less commonly assessed for in TBI although there is some evidence for impairment in the constructional and organisational skills aspects (McKenna, Cooke, Fleming, Jefferson, & Ogden, 2006).…”

Abstract. OBJECTIVE:To describe the long-term prevalence and severity of cognitive deficits following significant (i.e., ventilation required for >24 hours) traumatic brain injury. To assess a comprehensive range of cognitive functions using psychometric measures with established normative, reliability, and validity data. METHODS: A group of 71 adults was assessed at approximately five years (mean = 66 months) following injury. Assessment of cognitive functioning covered the domains of intelligence, attention, verbal and visual memory, visual-spatial construction, and executive functions. RESULTS: Impairment was evident across all domains but prevalence varied both within and between domains. Across aspects of intelligence clinical impairment ranged from 8-25%, attention 39-62%, verbal memory 16-46%, visual memory 23-51%, visual-spatial construction 38%, and executive functions (verbal fluency) 13%. In addition, 3-23% of performances across the measures were in the borderline range, suggesting a high prevalence of subclinical deficit. CONCLUSIONS: Although the prevalence of impairment may vary across cognitive domains, long-term follow-up documented deficits in all six domains. These findings provide further evidence that while improvement of cognitive functioning following significant traumatic brain injury may be possible, recovery of function is unlikely.

“…Visual perceptual deficits may be underestimated in aphasia. While the Rey copy is supported by simple verbal instructions, the complex copy task has been shown to involve planning and organization skills for successful completion (Schwarz, Penna, & Novack, 2009). Thus, the relationship with language performance and the Rey copy task could be partly explained by concomitant executive deficits in aphasia.…”

Up to 70% of stroke survivors experience cognitive impairments. Assessing cognitive skills after stroke is critical to diagnose, to educate, and to tailor rehabilitation to maximise functional outcomes. The neuropsychological tests used to assess cognition are typically pen-and-paper based, which are often dependent on language skills for completion.Language impairments observed in stroke survivors with aphasia may confound non-linguistic cognitive performance in these pen-and-paper tests. The primary objective of this research was to develop a clinimetrically sound cognitive assessment for stroke survivors with or without aphasia.A systematic review was conducted to determine whether studies that evaluated cognitive assessments in stroke included participants that represented the stroke population.Approximately two-thirds of the studies excluded individuals with communication problems, with a similar percentage of studies excluding individuals with cognitive impairments. This review highlighted the need for new and more feasible methods to assess cognition in the wider stroke population; particularly those with aphasia or cognitive impairment.We developed a non-immersive virtual reality cognitive assessment for individuals with stroke (with or without aphasia) -the Cognitive Assessment for Aphasia App (C3A). This "aphasia-friendly" assessment incorporated computerised audio and visual feedback, practice opportunities, and intuitive functional tasks to minimise dependency on language skills for completion. Developing the C3A required the input from a multidisciplinary clinical and research team and stroke survivors. We targeted cognitive domains that are commonly affected in stroke and that influence functional outcomes. The C3A included a simple reaction time task to assess psychomotor skills and attention, a visual search task to assess visuospatial skills, a sequence copy task to assess visual memory, and a kitchen task to assess executive functioning.A total of 97 participants were recruited (36 with aphasia, 29 stroke non-aphasia, 32 controls) from acute and inpatient rehabilitation settings and the community. All participants were assessed on the C3A and a battery of standard pen-and-paper cognitive tests typically used in stroke. Participants with aphasia and controls undertook the auditory comprehension sub-tests of the Comprehensive Aphasia Test. C3A performance iii measures included latency and errors. Following successful trials of the C3A we sought to determine its feasibility and validity in stroke and controls.Before analysing the C3A results, the association between language performance and the pen-and-paper cognitive tests in participants with aphasia and controls was explored. The association between language and a real-life measure of cognition (the Kettle Test) was also tested. All cognitive tests were significantly associated with auditory comprehension and naming performance (with up to 78% of variance explained), except for Star Cancellation and the Kettle Test. To measure non-lingu...
