“…2012). Importantly, this dissociation is frequently not accounted for when conducting research involving these reading impairments (Galletta, Campanelli, Maul, & Barrett, 2014;Leff & Behrmann, 2008). Failing to differentiate between these two independent cognitive impairments may potentially confound efforts to investigate these conditions' underlying attentional biases, neural correlates, and recovery trajectories.…”

Consistently lateralized reading errors are commonly understood as side-effects of visuospatial neglect impairment. There is however a qualitative difference between systematically omitting full words presented on one side of passages (egocentric neglect dyslexia) and lateralized errors when reading single words (allocentric neglect dyslexia). This study aims to investigate the relationship between egocentric and allocentric neglect dyslexia and visuospatial neglect. 1209 stroke survivors completed standardized reading and cancellation tests. Stringent criteria identified unambiguous cases of allocentric neglect dyslexia (N = 17) and egocentric neglect dyslexia (N = 35). These conditions were found to be doubly dissociated with all cases of egocentric and allocentric neglect dyslexia occurring independently. Allocentric neglect dyslexia was dissociated from both egocentric and allocentric visuospatial neglect. Additionally, two cases of allocentric neglect dyslexia which co-occurred with oppositely lateralized domain-general visuospatial neglect were identified. Conversely, all cases of egocentric neglect dyslexia were found in the presence of domain-general visuospatial neglect. These findings suggest that allocentric neglect dyslexia cannot be fully understood as a consequence of visuospatial neglect. In contrast, we found no evidence for a dissociation between egocentric neglect dyslexia and visuospatial neglect. These findings highlight the need for new, neglect dyslexia specific rehabilitation strategies to be designed and tested.

“…1 Individuals with disordered spatial cognition, which can affect perception and mental representation of spatial information, as well as planning and execution of motor actions, demonstrate failure or slowness to respond, orient, or initiate action towards contra-lesional stimuli, 2 and they may have difficulty in generating contra-lesional mental imagery. 3 Although features of spatial neglect may vary between individuals, the clinical syndrome is defined by deficits that disrupt functions essential in daily life, such as mobility (walking, 4,5 wheelchair use, 6 and driving), 7 reading, 8,9 or appropriate social interactions. 10 …”

Objective To examine the impact of spatial neglect on rehabilitation outcome, risk of falls, and discharge disposition in stroke survivors. Design Inception cohort Setting Inpatient rehabilitation facility (IRF) Participants 108 individuals with unilateral brain damage after their first stroke were assessed at the times of IRF admission and discharge. At admission, 74 of them (68.5%) demonstrated symptoms of spatial neglect, as measured with the Kessler Foundation Neglect Assessment Process (KF-NAP™). Interventions Usual and standard IRF care. Main Outcome Measures Functional Independence Measure (FIM™), Conley Scale, number of falls, length of stay (LOS), and discharge disposition. Results The greater severity of spatial neglect (higher KF-NAP scores) at IRF admission, the lower FIM scores at admission as well as at discharge. Higher KF-NAP scores also correlated with greater LOS and slower FIM improvement rate. The presence of spatial neglect (KF-NAP > 0), but not Conley Scale scores, predicted falls such that participants with spatial neglect fell 6.5 times more often than those without symptoms. More severe neglect, by KF-NAP scores at IRF admission, reduced the likelihood of returning home at discharge. A model that took spatial neglect and other demographic, socioeconomic, and clinical factors into account predicted home discharge. Rapid FIM improvement during IRF stay and lower annual income level were significant predictors of home discharge. Conclusions Spatial neglect following a stroke is a prevalent problem, and may negatively affect rehabilitation outcome, risk of falls, and length of hospital stay.

“…1-7 Individuals with spatial neglect demonstrate a failure or slowness to respond, orient, or initiate action towards contra-lesional stimuli. 8 Therefore, spatial neglect disrupts mobility and navigation (walking, 9 wheelchair ambulation, 10 and driving), 11 reading, 12 and social interactions. 13 Patients with this disorder have poorer rehabilitation outcomes, experience greater safety risk during hospitalization, and are hospitalized longer as compared to those without spatial neglect.…”

Objective To explore the factor structure of the Kessler Foundation Neglect Assessment Process (KF-NAP), and evaluate the prevalence and clinical significance of spatial neglect among stroke survivors. Design Inception cohort. Setting Inpatient rehabilitation facility (IRF). Participants 121 participants with unilateral brain damage from their first stroke were assessed within 72 hours of admission to an IRF, and 108 were assessed again within 72 hours before IRF discharge. Interventions Usual and standard IRF care. Main Outcome Measures During each assessment session, occupational therapists measured patients’ functions with the KF-NAP, Functional Independence Measure (FIM™) and Barthel Index (BI). Results The KF-NAP showed excellent internal consistency with a single-factor structure. The exploratory factor analysis revealed the KF-NAP to be unique from both the FIM and BI even though all three scales were correlated. 67.8% of the participants at admission and 47.2% at discharge presented with symptoms of spatial neglect (KF-NAP > 0). Participants showing the disorder at IRF admission were hospitalized longer than those showing no symptoms. Among those presenting with symptoms, the regression analysis showed that the KF-NAP scores at admission negatively predicted FIM scores at discharge, after controlling for age, FIM at admission, and length of stay. Conclusions The KF-NAP uniquely quantifies symptoms of spatial neglect by measuring functional difficulties that are not captured by the FIM or BI. Using the KF-NAP to measure spatial neglect, we found the disorder persistent after inpatient rehabilitation, and replicated previous findings showing that spatial neglect adversely affects rehabilitation outcome even after prolonged IRF care.
