Ameliorating neglect with prism adaptation: visuo-manual and visuo-verbal measures

A Farnè
2002 Neuropsychologia  
Previous studies have shown that adaptation to rightward displacing prisms improves performance of neglect patients on visuo-manual (VM) tasks such as line cancellation, figure copying, and line bisection  ...  We investigated these issues in a group of neglect patients with right hemispheric damage who were also affected by neglect dyslexia.  ...  Materials To assess neglect severity, a battery of eight visuo-spatial tasks was administered to each patient.  ...

2009 Cortex  
Eight such neglect patients showed perseveration in both cancellation and drawing tasks, although no correlation was found with the severity of neglect.  ...  Patients with perseveration were not disproportionately impaired in tasks assessing executive (fluency, Stroop colour-word interference, and Weigl's sorting test), and visuo-spatial short-term memory function  ...  is a pathological phenomenon that spans across visuo-motor tasks with different specific features, such as cancellation and drawing.  ...

S P Stone, B Wilson, A Wroot, P W Halligan, L S Lange, J C Marshall, R J Greenwood
1991 Journal of Neurology, Neurosurgery and Psychiatry  
Forty four consecutive patients with acute hemispheric stroke and forty seven elderly controls with no neurological disease were assessed for visuo-spatial neglect, using a modified neglect test battery  ...  The battery was validated against an occupational therapist's assessment of neglect on self-care tasks.  ...  A fundamental feature of patients with visuo-spatial neglect due to a right hemisphere lesion is that they begin tasks on the right hand side.2223 In four of the eight tests, the presence of a "Right Hand  ...

'Pure' Constructional Apraxia—A Cognitive Analysis of a Single Case

Luigi Trojano, Dario Grossi
1998 Behavioural Neurology  
To identify the cognitive impairment in this patient, we adopted two test batteries based on recent information-processing models of drawing.  ...  Results showed that the patient's drawing disabilities were independent of visuo-perceptual and executive impairments.  ...  The aim of the authors is to assess visuo-spatial abilities thought to be involved in the preliminary analysis of stimuli, and, on the other hand, several aspects of spatial cognition likely related to  ...

2014 PLoS ONE  
Furthermore, we observed that 20.56% of the patients were considered affected or not by neglect on the line bisection task compared with the other spatial tasks of the hemineglect battery.  ...  Our results showed that performance of the line bisection task correlates with performance of cancellation tasks, reading and perceptual tasks, but not with the presence of personal neglect.  ...  The skills assessed by drawing were related to both perceptual and visuo-motor aspects [16] .
