“…Task complexity can affect performance (Blini et al, 2016;Bonato, 2012). Tasks that involve multiple steps or require people to multitask may also be more sensitive to detecting neglect (Blini et al, 2016;Bonato, 2012), which may explain why the VRLAT and NAT detected that all participants had neglect. The VRLAT and NAT may be more sensitive at distinguishing people with mild neglect because of their complex demands (e.g., auditory and visual distractors, multiple steps).…”

“…The tenet that functional assessments may be more sensitive to neglect than paper-and-pencil assessments has support (Azouvi et al, 2006;Blini et al, 2016;Pedroli, Serino, Cipresso, Pallavicini, & Riva, 2015). Functional tasks require a person to pay attention to objects placed near the body (personal), around the body (peripersonal), and away from the body (extrapersonal).…”

OBJECTIVE. We determined whether various assessment tools detect neglect differently by administering a battery of assessments to people with stroke. METHOD. We conducted a case series study and administered five neglect assessments (paper-and-pencil, functional, virtual reality) to participants poststroke. RESULTS. Twelve participants (6 men, 6 women) with stroke completed the assessment battery, which required approximately 2 hr to administer (over one to two sessions). All participants demonstrated neglect on three or more assessments. Functional assessments and the virtual reality assessment detected neglect more frequently than the paper-and-pencil assessments. Participants performed differently on the paper-and-pencil assessments and functional assessments. CONCLUSION. Because neglect is complex, detection may depend largely on the assessment administered.

Dissociating ego- and allocentric neglect after stroke: prevalence, laterality and outcome predictors

Visuospatial neglect is a neuropsychological condition commonly experienced after stroke, whereby a patient is unable to attend to stimuli on their contralesional side.We aimed to investigate whether egocentric and allocentric neglect are functionally dissociable and differ in prevalence, laterality and outcome predictors. A consecutive sample of 366 acute stroke patients completed the Broken Hearts test from the Oxford Cognitive Screen. A subsample of 160 patients was followed up 6 months later. We evaluated the association between egocentric and allocentric neglect, contrasted the prevalence and severity of left-sided versus right-sided neglect, and determined the predictors of persistence versus recovery at follow up. Clinically, we found a double dissociation between ego-and allocentric neglect, with 50% of the neglect patients showing 'only' egocentric neglect and 25% 'only' allocentric neglect.Importantly, patients with only allocentric neglect did not demonstrate any egocentric spatial bias in the locations of the allocentric errors. Left-sided egocentric neglect was more prevalent and more severe than right-sided egocentric neglect, though right-sided neglect was still highly prevalent in the acute stroke sample (35%). Leftsided allocentric neglect was more severe but not more prevalent than right-sided allocentric neglect. Overall recovery of neglect was high: 81% of egocentric and 75% of allocentric neglect patients recovered. Severity of neglect was the only significant behavioural measure for predicting recovery at 6 months.

“…The same holds true for the control group: it might well be that patients assigned to that group could have had subclinical forms of neglect not easily detectable with standard pencil and paper tasks (Bonato et al., ; Bonato, ; Sperber and Karnath, ). Very recent studies even suggest that with the appropriate testing, neglect symptoms can be observed in patients with left‐hemisphere stroke (Blini et al., ).…”
