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...

OBJECTIVES To clarify the reason why patients with left unilateral spatial neglect fail to copy the left side of a daisy like flower, not continuing to draw petals all around. METHODS A flower was simplified and a figure was made that consisted of a large central circle and small circles surrounding it. Four patients with typical left unilateral spatial neglect performed copying and arrangeme...

This review examines the treatment perceptual disorders following stroke focussing primarily on unilateral spatial neglect (USN). Unilateral spatial neglect is reported in about 25% of stroke patients referred for rehabilitation and is more commonly associated with right parietal lesions. Unilateral spatial neglect has been reported to have a negative impact on functional recovery, length of re...

After right posterior brain damage, patients may ignore events occurring on their left, a condition known as unilateral neglect. Although deficits at different levels of impairment may be at work in different patients, the frequency and severity of attentional problems in neglect patients have been repeatedly underlined. Recent advances in the knowledge of the mechanisms of spatial attention in...

Anderson et al. (Variability not ability: another basis for performance decrements in neglect. Neuropsychologia 2000;38:785-796) have recently reported that variability of response times (RTs) progressively increases from the right to the left side in left neglect patients. Anderson et al. propose that this lack of consistency is an important determinant of patients' behaviour, and may result f...

OBJECTIVES To review the existing literature on treatments of unilateral neglect, to synthesize findings, and to offer recommendations for future studies. DATA SOURCES Computerized databases including MEDLINE and PsychINFO. STUDY SELECTION All studies investigating treatment(s) of unilateral neglect. DATA EXTRACTION Authors reviewed design and other methodologic issues. DATA SYNTHESIS U...

BACKGROUND Patients with unilateral neglect fail to respond normally to stimuli on the left side. To facilitate the evaluation of unilateral spatial neglect, we developed a new application that runs on a tablet device and investigated its feasibility in stroke patients. METHODS We made the computerized table setting test (CTST) to run on the tablet computer. Forty acute ischemic stroke patien...

Temporality enters our immediate experience as passage and becoming: the role time plays in the construction of a world of enduring entities tends to go unnoticed. This paper examines the relation between time and ontology in the context of unilateral neglect, a neuropsychological syndrome in which patients fail to perceive or respond to stimuli in the contralateral hemifield, behaving as if th...

Detailed analyses of reading and nonlexical tasks by three patients with unilateral spatial neglect (USN) secondary to stroke indicate that the USN in each of these patients affects the left side (contralateral to brain damage) of the viewer, with respect to the viewer's head, mid-sagittal plane of the body, or line of sight. In one case, the neglect was further specified as concerning the left...
