Typically, the syndrome occurs following a lesion of the right parietal cortex of the brain, and the left side of the body or space is neglected. Although the syndrome is traditionally most closely associated with parietal lesions,36 most middle cerebral artery strokes affect several regions and many patients show varying combinations of parietal, temporal and frontal damage.37 In addition, neglect can follow subcortical stroke, although this may relate to hypoperfusion and dysfunction Perseverations in left neglect patients can be the result of the combined effect of restriction to the contralesional side of space due to (mainly) right parietal lesions, on the one hand, and of the impairment in inhibiting motor responses related to basal ganglia lesions, on the other hand. Spatial neglect is defined as pathologically asymmetric spatial behavior, caused by a brain lesion and resulting in disability. [ 1 , 2 , 3 ] As we identify input, knowledge storage, and output information processing stages in aphasia and other cognitive disorders, [ 4 ] we can also identify modular, stagewise spatial cognitive processing. neglect. All of the patients had pusher syndrome due to left-sided brain lesions rather had aphasia.11 We conclude that both neglect and aphasia are highly associated with pushing behavior after right-side brain damage (3neglect) and after left-side brain damage (3 aphasia), but that both disorders neglect and aphasia Left neglect after stroke is a peculiar disorder that can lead to strange behavior. For instance, patients with left neglect may only eat from the right side of their plates.

Many early studies hypothe sized that neglect was simply the result of a loss of sen sation or perception (Battersby, Bender, Pollack, & Kahn, 1956; Denny-Brown, Meyer, & Horenstein, 1952; MeFie, Pierey, & Zangwill, 1950). Subsequent theorists have proposed that neglect is due either to an imbalanee A widely cited operational definition states that persons with neglect fail to report, respond, or orient to external stimulation (or mental representations of sensory events) located contralateral to a brain lesion (i.e., contralesional) when the failure cannot be attributed to a primary sensory or motor deficit such as hemianopia or paralysis (Heilman, Watson, & Valenstein, 1985).

It is considered that the patients could execute leftward movements as the task oriented their attention sufficiently to the left.

Neglect, also known as unilateral neglect, hemispatial neglect, hemineglect, neglect syndrome, or spatial neglect, is a disabling brain disorder, usually caused by a brain lesion. Patients with neglect typically have difficulty paying attention to contralesional space. Thus, if the lesion causing the neglect occurs in the right cerebral cortex, the patient may find it difficult to attend to an object situated to the left of their current point of fixation. This syndrome is observed primarily after unilateral lesions to the parieto-occipital junction, especially in the right hemisphere (Heilman, Watson, and Valenstein 1985; Bisiach 1996). Lesions to the right frontal cortex and to various subcortical sites can also trigger neglect-like symptoms, although with subtle differences from parietal neglect (Heilman et al.

In sensory neglect, patients ignore visual, somatosensory, or auditory stimuli on the affected side, despite intact primary sensation (see Neuroanatomy through Clinical Cases, Chapter 19). Neglect has been described also in animals (monkey, cat, rat) with, however, no hemispheric asymmetries. Patients with neglect fail to orient to events (visual, auditory, tactile stimuli) occurring on the side of space contralateral to the side of the lesion (i.e., the left-hand side in right-brain-damaged patients) and to explore it.
