False lateralization of seizure perceived by a patient with infarction of the right parietal lobe who showed the neglect syndrome.

A 66-year-old right-handed man developed seizures characterized by an electric sensation and convulsive movements involving the left arm, which sometimes secondarily generalized. The patient, however, reported that the seizures occurred in his right arm. Neurological examination showed many features of left hemineglect, including allesthesia, secondary to acute infarction of the right parietal lobe. Although allesthetic response was not documented during the seizure, it is likely that sensory symptoms of the seizures were localized inappropriately or that he had false memory for lateralization of seizures. In this case, the neglect syndrome caused by infarction of the right parietal lobe extended to symptoms of the seizure itself.

Response-to-next-patient-stimulation: a right hemisphere syndrome.

Eleven of 134 patients with a right hemisphere stroke responded to stimuli directed at other patients as if the stimuli were directed at them. The stroke was severe in all 11 patients. Associated disturbances included hemineglect, anosognosia, motor impersistence, disorientation (sometimes with agitated confusion), and somatosensory delusions and allesthesia. This form of perseveration seems specific to acute right hemispheric stroke.

Visual environmental rotation: a novel disorder of visiospatial integration.

A 70-year-old man experienced an unusual disorder of visual perception after undergoing a ventriculoperitoneal shunt for normal-pressure hydrocephalus. The disorder was characterized by transient episodes of 90 degrees rotation of the visual environment, rather than the retinotopic visual field. This phenomenon is different from standard visual allesthesia and may have been caused by disordered integration of vestibular and visual inputs to the posterior parietal cortex or perseveration of a pre-existing environmental memory trace.

[Attention systems and unilateral neglect].

Unilateral neglect can be defined as an impairment to detect, refer, orient or respond to stimuli presented contralaterally to a cerebral lesion, without any impairments in sensory-motor elementary functions. Development. The first descriptions were those of Hughlings Jackson (1876) and Anton (1893). The most important feature of the syndrome is a lateralization bias, which is directional in nature independently of the visual fields. It can be classified in: 1. Attentional (sensory neglect). 2. Intentional (motor neglect). The lesions that may be responsible for the neglect syndromes are usually found in the inferior parietal cortex of the right cerebral hemisphere (superior parietal when optic ataxia is prominent), and the right frontal lobe. Extinction is more frequently related to subcortical lesions (right lenticular nucleus, anterior aspects of peri-ventricular white matter). Unilateral neglect comprises a set of features that may coexist or be isolated traits: 1. Attentional neglect: hemi-inattention, allesthesia, allochiria, anosognosia (with/without somato-paraphrenia or misoplegia), and anoso-diaphoria, sensory extinction. 2. Intentional neglect: hemi-akinesia, directional hypokinesia, motor impersistence, motor extinction. Different theories try to explain the patho-physiology of these phenomena: the attentional-intentional model, the neural network model, the vectorial model, the representational model, and the premotor model, among others.
