Spatial and non-spatial aspects of neglect

Spatial and non-spatial aspects of neglect

Deficits of contralesional space awareness (neglect and extinction) often follow right hemisphere damage and are typically attributed to the disruption of neurocognitive mechanisms subserving orienting of attention in space (Driver and Vuilleumier, 2001). Neglect affects awareness of contralesional stimuli, whereas extinction affects contralesional awareness only when competing stimuli are pres...

Spatial neglect

The syndrome of visuospatial neglect is a common consequence of unilateral brain injury. It is most often associated with stroke and is more severe and persistent following right hemisphere damage, with reported frequencies in the acute stage of up to 80%. Neglect is primarily a disorder of attention whereby patients characteristically fail to orientate, to report or to respond to stimuli locat...

Acute versus chronic functional aspects of unilateral spatial neglect.

This article reviews the impact of unilateral spatial neglect on daily living ("functional") activities. Its disturbances on basic functional activities, such as feeding, grooming, and locomotion, are easily identifiable. Patients with neglect frequently lack insight into their disorder and do not initiate compensatory behaviors, which probably impedes recovery. Simple standard tests of neglect...

Reward modulates spatial neglect

BACKGROUND Reward has been shown to affect attention in healthy individuals, but there have been no studies addressing whether reward influences attentional impairments in patients with focal brain damage. METHODS Using two novel variants of a widely-used clinical cancellation task, we assessed whether reward modulated impaired attention in 10 individuals with left neglect secondary to right ...
