Strategy Training for Individuals With Unilateral Neglect

Start date: July 1, 2024
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06050408 Not yet recruiting - Clinical trials for Neglect, Hemispatial

Assessment of LF-rTMS in Patients With Visual Neglect

Start date: September 15, 2023
Phase: N/A
Study type: Interventional

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).

NCT ID: NCT05654350 Completed - Stroke Clinical Trials

Lesion Site and Neglect Anosognosia in Patients With Left Hemispatial Neglect

Start date: December 16, 2022
Phase:
Study type: Observational

The goal of this retrospective is to investigate the relationship between lesion site and neglect anosognosia in subacute or chronic right hemispheric stroke patients with left hemispatial neglect. The main questions it aims to answer are: - Was any lesion site related to a higher neglect anosognosia rate? - Did any lesion site related to a more severe neglect anosognosia? Participants will be divided into two groups regarding the presence of anosognosia for spatial neglect. Researchers will compare patients with and without anosognosia to see if any lesion site resulted in a higher anosognosia rate and more severe unawareness of neglect symptoms in daily life.

NCT ID: NCT05332964 Enrolling by invitation - Stroke Sequelae Clinical Trials

Virtual Reliability System for Visual Spatial Attention Evaluation in Stroke Patients

Start date: August 24, 2021
Phase:
Study type: Observational

The researchers designed a software based on a head-mounted displays for virtual reality (HMD-VR) to evaluate the reaction time to stimuli presented at right or left visual field. The study will recruit 100 stroke patients with hemisphere lesions (50 patients for right and left each) and 100 age-matched healthy controls. The participants will conduct a simple reaction time task in VR, with stimuli designated in the left or right hemi-field. The stroke patients will also received traditional tests for hemi-neglect. Test-retest reliability of the assessment will be conducted in a subset of the control group. The stroke patients will be followed in 3-4 weeks.

Improving Awareness for Spatial Neglect With tDCS

ANOSO
Start date: September 1, 2022
Phase: N/A
Study type: Interventional

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.

tDCS in Post-stroke Neglect Rehabilitation

tDCS-Neglect
Start date: November 8, 2019
Phase: N/A
Study type: Interventional

Introduction Stroke is the main cause of disability in the world and its sequelae have a great impact in the functional independence and quality of life of patients and families. Unilateral spatial neglect is one of the most frequent cognitive deficits after stroke, and its maintenance is associated with poor functional outcome of the rehabilitation process. For many years clinical research has been conducted to develop new and effective rehabilitation strategies for neglect. Noninvasive brain stimulation (NIBS) techniques are important tools in this regard, and it should be considered as a therapeutic intervention used in combination with conventional neuropsychological approaches. Transcranial direct current stimulation (tDCS) is a noninvasive, safe, neurophysiological technique able to modulate cortical activity by inducing a weak electric current into the brain. The studies focused on neglect symptoms treatment by means of tDCS over the lesional and contralesional hemisphere have shown promising results and its combination with conventional neglect therapies may enhance treatment efficacy and speed the recovery. Objectives To improve neglect symptoms by reducing the pathological hyperactivity of the undamaged hemisphere after right medial cerebral artery stroke, through the application of multisite tDCS, and to validate a NIBS protocol for the enhancement of conventional neuropsychological rehabilitation outcome. Methods The sample will be composed by 30 patients with spatial neglect secondary to a ischemic stroke in the middle cerebral artery in subacute stage (3 to 12 months since the event). The patients will be randomly assigned to one experimental group (Active, Sham, and Control). The intervention protocol consists in a two weeks intervention (10 sessions, 45 min, Monday to Friday) of tDCS and neuropsychological rehabilitation applied concurrently. In each session a 20 min tDCS at 2 milliamps (m will be applied over P3 according to 10/20 EEG international system (cathodal) with return electrodes placed in C3,CP5,CP1,Pz,PO3,PO7,P7 (10/20 EEG). StarStim® tDCS 8 channels Multisite device will be used.
