View clinical trials related to Spatial Neglect.
Filter by:Spatial neglect represents a common and severe cognitive disorder following unilateral (mostly right hemisphere) stroke. Patients are unaware of objects, persons and even own body parts in the (usually left) hemispace opposite to their brain lesion. While there is spontaneous remission in some patients, neglect symptoms persist in many stroke survivors which is associated with a poor functional outcome. Although different therapeutic approaches (including cognitive interventions, non-invasive brain stimulation and drugs) have been investigated in the last decades, an established therapy is still missing. Hence, there is a clear need for an effective and feasible intervention that can be applied in rehabilitation centers. This study is dedicated to assess the effect of a cognitive treatment consisting of combined optokinetic stimulation (OKS) and cueing-based reading therapy (READ) on hemispatial neglect and the neglect-related functional disability in right-hemisphere stroke patients. It will be a mono-centric, randomized, controlled, clinical trial. Using a crossover design with two arms, patients will either receive the intervention therapy (OKS-READ) first and subsequently the control treatment (neuropsychological training not targeting visuospatial attention) or they will start in the control arm and then switch to the intervention. Each treatment phase consists of 15 therapy sessions lasting 30 to 45 minutes. The outcome will be assessed at different time points, including established neuropsychological tests for spatial neglect and a clinical score of neglect-related functional disability.
The aim of this study is to investigate the effect of training with an adaptive computer game, in comparison to standard training, in the rehabilitation of stroke survivors suffering from spatial neglect.
A brain injury can damage the brain, so that it no longer receives information about the space around one side of the world. If this happens, people may not be aware of anything on one side, usually the same side they also lost their movement (the most affected side). This severe condition is called spatial neglect. Currently there is no recommended diagnostic test or clinically-proven treatment for the condition. In a recent study, the investigators found a long-lasting reduction in neglect if people practiced picking-up an object with their unaffected hand. This intervention is called Spatial Inattention Grasping Home-based Therapy (SIGHT). It requires people to lift wooden rods of different lengths. Once a person is familiar with the task, they can practice on their own at a time convenient to them in their homes. The investigators have developed the first computerized version of SIGHT (c-SIGHT) as well as a novel diagnostic test for neglect using portable low-cost motion-tracking technology that can be used in the patient's home. In the proposed study, the investigators will investigate how usable and acceptable this technology is in people's homes. Stroke survivors (recruited from community settings) will undergo a 7-day self-led training at their homes with c-SIGHT. At the end of the intervention, 1:1 semi-structured interviews will be carried out with both stroke survivors and carers to investigate usability and acceptability of c-SIGHT. Moreover, spatial neglect, carer burden and motor function will be assessed pre- and post-completion of c-SIGHT.

Spatial neglect may occur in patients who have had a stroke. People with spatial neglect often pay much more attention to one side of the body while ignoring the other side, even though they have no difficulty seeing. The purpose of this study is to evaluate the impact on stroke recovery, including spatial neglect, of the Family-Clinician Collaboration program, where a family member of a stroke survivor actively interacts with clinical staff members providing inpatient rehabilitation services to the stroke survivor.
The goal of this study is to understand what brain mechanisms become disrupted when stroke survivors experience delirium. Delirium is an acute reduction in attention and cognition, associated with poor recovery, longer hospitalization and even death. One major factor increasing the risk of delirium after stroke may be spatial neglect occurring after stroke on the right side of the brain. Spatial neglect affects awareness, orientation, and movement. The study will test the hypothesis that the right-dominant brain networks for arousal and attention are affected in both of these disorders. It is expected that the activity and structural integrity of these brain networks will correlate with behavioral signs and severity of delirium and spatial neglect. To test this hypothesis, the study will measure spatial neglect and delirium symptoms in 45 acute (NYC Health + Hospitals/Bellevue ) and 30 subacute (Kessler Institute for Rehabilitation) stroke survivors and evaluate brain scans for these participants. This study may contribute to knowledge about brain bio-markers of delirium, which will greatly aid in delirium detection in stroke and other disorders.
The present study aims to compare the relative therapeutic efficacy of prism adaptation therapy combined with real versus sham tDCS. The investigators will test the hypothesis that the magnitude and duration of neglect improvement will be increased when prism therapy is combined with real tDCS compared to sham tDCS. A second objective is to test whether individual differences in baseline clinical or brain imaging measures can predict: 1) neglect severity or 2) inter-individual differences in patients' therapeutic response. A third goal is to use brain imaging to characterize the patterns of neural change induced by the intervention to identify brain structures that mediate therapeutic response.
The purpose of this study is to determine if stroke survivors with aphasia have spatial neglect (Phase 1). If they are determined to have the condition Phase 2 will be offered: which is prism adaptation treatment. This is a pilot study that will be performed with 4-5 subjects.
Spatial neglect represents one of the major cognitive disorders following stroke. Patients patients fail to be aware of objects or people to their left and orientate instead to their right side. Enduring neglect has been found to be a poor prognostic indicator for functional independence following stroke. Despite some promising experimental accounts there are no established treatments for this condition. The aim of this study is to test whether a combined treatment with hemifield eye patching (HEP) and optokinetic stimulation (OKS) can permanently reduce neglect behaviour and improve functional outcome in patients with hemispatial neglect following stroke. The investigators hypothesise that the treatment with HEP and OKS will lead to a greater reduction of neglect scoring in the neglect test battery as well as a greater improvement in functional independence scores as compared to the spontaneous clinical course of the usual-care control group.
Compared to the classical "paper and pencil"-tests, testing patients in our virtual reality setup might have a higher sensitivity and specificity.
