Filter by:It is common for individuals after stroke to have a cognitive perceptual impairment called unilateral spatial neglect (neglect). Individuals with neglect have difficulty paying attention to one side of their body or one side of the environment and therefore experience difficulty performing daily activities. There are a lack of effective treatments for neglect and new interventions are needed to help reduce disability for these individuals. Metacognitive strategy training (strategy training) is an intervention that has the potential to reduce neglect-related disability and improve individuals' awareness of their neglect. This study seeks to examine the effects of strategy training on self-awareness, disability, and neglect.
Visual neglect is a common disorder following stroke and an indicator of poor recovery compared to stroke survivors without visual neglect. The goal of this intervention study is to assess the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in reducing visual neglect symptoms in patients following a stroke. The aim is to answer these questions: 1. Does rTMS decrease visual neglect symptoms in patients following a stroke? 2. If the treatment works, when in the rehabilitation process is it most effective to provide the treatment (6-12 weeks, 16-42 weeks or 52+ weeks after the stroke).
Brain-damaged patients can show severe neurological and cognitive deficits, and yet often remain strikingly unaware of these symptoms: this condition is called anosognosia. The aim of this study is to improve awareness in right-brain-damaged patients with Unilateral Spatial Neglect (USN) following stroke using transcranial direct current stimulation (tDCS). tDCS is a neuromodulatory technique that delivers low-intensity current to the brain facilitating (anodal tDCS) or inhibiting (cathodal tDCS) spontaneous neuronal activity. tDCS does not induce activity in resting neuronal networks, but modulates spontaneous neuronal activity: consequently, the amount and direction of effects critically depend on the previous state of the neural structures. We will test USN patients showing anosognosia for neglect symptoms. Different brain areas will be stimulated, to target explicit and implicit components of anosognosia, including parietal and frontal brain regions.
