Can mirrors alleviate visual hemineglect?
Following right hemisphere stroke, many patients display an indifference to objects and events in the left side of the world ('neglect'). Here, we describe a new technique that might help accelerate recovery from neglect. The patient sits at a table and a mirror is propped vertically on the patient's right side in the parasagittal plane, so that when the patient rotates his head rightward and l...
متن کاملEvidence of visual hemineglect in an archeological specimen?
Fetal PCA, when present, originates from the internal carotid artery (ICA) and it is supplied by the carotid system rather than the vertebro-basillary system. Fetal type posterior (FTP) circulation variation has been reported in 3-36% in the literature. Three types have been described: Transitional configuration, partial FTP and full FTP. In FTP, leptomeningeal collaterals cannot provide the PC...
متن کاملParallel interhemispheric processing in hemineglect: relation to visual field defects.
Parallel interhemispheric processing is required to explore our visual environment and to integrate visual information from both hemifields simultaneously. Damage to the right temporo-parietal cortex can disrupt such parallel processes and result in neglect and visual extinction of stimuli in the left contralesional visual space. Neglected or extinguished stimuli can still be processed, yet wit...
متن کاملBilateral vestibular stimulation does not improve visual hemineglect.
This work compared the effect of unilateral (right and left) and bilateral vestibular stimulation in a right-brain-damaged patient with neglect. Neglect was improved following left caloric vestibular stimulation, and worsened following right vestibular stimulation. On the other hand, no modification of neglect was observed after bilateral vestibular stimulation. These results support the idea t...
متن کاملBuccal hemineglect.
OBJECTIVES To determine whether the peripersonal and intrapersonal buccal space can be affected by a hemispheric stroke and to evaluate the clinical signs resulting from buccal neglect. METHODS A prospective study comparing 2 groups of patients with hemiplegia, 1 with a right hemispheric lesion and the other with a left hemispheric lesion. Patients were selected consecutively on the basis of ...
