Aspectos clínicos y modelos teóricos en el Síndrome de Neglect

Abstract

This paper reviews the syndrome Neglect considering different theoretical models: attentional direction; of cerebral hemispheric asymmetry, attentional bias, selective attention model. The cognitive, emotional and neurobehavioral characteristics are highlighted. Neglect syndrome usually results from a stroke that affects the right cerebral hemisphere and points directly to the parietal lobe. This is the result of an extensive anatomical definition more than that one functional unit or physiological. The syndrome is manifested by deficits in attention and perceptual responses to stimuli presented in the contralesional hemispace. Neglect is a heterogeneous syndrome. Despite the preponderance of theories of the attentional deficit, explanations of perceptual deficits and representation of space are present. The syndrome manifestations are the heminatención, the extinction, the hemispatial hemicinesia and the neglect. They are very important the emotional aspects as the cognitive, neurobehavioral and motor rehabilitation, in the neuropsychological rehabilitation process of syndrome. Symptoms of anosognosia, extinction, behavioral disinhibition, and the utilization behavior or lack of affection are the most prominent in the syndrome. In terms of recovery, how to happen this? We discuss several alternative explanations and the role of motivation as an important factor in the success of treatments.
