“…For wheelchair users, visual field neglect increases the risk of colliding with obstacles or missing important navigational cues in the neglected side. Among other diagnoses, visual field neglect can result from right-hemisphere CVA (13%-82% of cases), left-hemisphere CVA (0%-76%) [24], or severe TBI (45%) [58].…”

“…Depending on which part of the brain is injured, severe TBI can result in diverse physical, cognitive, and perceptual symptoms. Potential symptoms include visual field neglect, hemiplegia, tremors, bradykinesia, fatigue, and posttraumatic epileptic seizures, in addition to impairments in attention, impulse control, and executive reasoning [53][54][55][56][57][58].…”

Abstract-Independent mobility is important, but some wheelchair users find operating existing manual or powered wheelchairs difficult or impossible. Challenges to safe, independent wheelchair use can result from various overlapping physical, perceptual, or cognitive symptoms of diagnoses such as spinal cord injury, cerebrovascular accident, multiple sclerosis, amyotrophic lateral sclerosis, and cerebral palsy. Persons with different symptom combinations can benefit from different types of assistance from a smart wheelchair and different wheelchair form factors. The sizes of these user populations have been estimated based on published estimates of the number of individuals with each of several diseases who (1) also need a wheeled mobility device and (2) have specific symptoms that could interfere with mobility device use.

“…This domain of cognitive functioning is even less frequently researched in TBI outcome studies than visual memory. However there is some indication that researchers are beginning to incorporate this domain into their assessment protocols and one short-term follow-up study reported 26% of severe TBI patients to have deficits in constructional skills (McKenna et al, 2006). Given the fact that assessment of visual memory frequently requires the drawing of geometric shapes, assessment of the domain of visual-spatial construction is essential in order to ensure that performance on a visual memory measure is not confounded by impairment in visual-spatial constructional abilities (Ashton et al, 2005).…”

“…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). Executive function is perhaps the most multifaceted domain of cognitive functioning and the aspect of verbal fluency has been consistently shown to demonstrate impairment following TBI (Henry & Crawford, 2004).…”

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.

“…It is, therefore, not surprising that acquired brain injury (ABI; e.g., stroke, brain tumor, traumatic brain injury, or neurodegenerative diseases) frequently results in visual perceptual disorders (Costa et al, 2015;Greenwald, Kapoor, & Singh, 2012;Husain & Rorden, 2003;Lincoln, 1995;K. McKenna, Cooke, Fleming, Jefferson, & Ogden, 2006;Riggs, Andrews, Roberts, & Gilewski, 2007).…”
