Brain-computer interfaces (BCIs) are anticipated to improve the efficacy of rehabilitation for people with motor disabilities. However, applying BCI in clinical practice is still a challenge due to the great diversity of patients. In the current study, a novel action observation (AO) based BCI was proposed and tested on stroke patients. Ten non-hemineglect patients and ten hemineglect patients were recruited. Four AO stimuli were designed, each presenting a decomposed action to complete the reach-and-grasp task...

Visual field loss and visuospatial neglect are frequent consequences of cerebral stroke. They often have a strong impact on independence in many daily activities. Rehabilitation aiming to decrease these disabilities is therefore important, and several techniques have been proposed to foster awareness, compensation, or restitution of the impaired visual field. We here describe a rehabilitation intervention using adapted boxing therapy that was part of a pluridisciplinary intervention tailored for a particular case...

A male patient in his 40s with a history of nephrolithiasis and found in the desert after 10 days without oral intake was admitted to the hospital for severe dehydration, acute kidney injury and rhabdomyolysis. He had acute-onset loss of consciousness during hospitalisation with new left-sided hemiparesis and hemineglect. After haemorrhage was excluded, prompt thrombolysis was given. He later had chest pain and became hypotensive. An echocardiogram revealed pericardial effusion and dilation of the ascending aorta with suspected dissection...

OBJECTIVES: Attention is an essential part of cognitive functions for all learning in the school environment. The screening of attentional deficits constitutes an important field of research, given its relationship with other cognitive functions and the neurocognitive profiling of Moroccan adolescents in school. MATERIALS AND METHODS: A study was conducted over 3 months. A comparative and predictive method is used, the Bells test, to assess the state of neglect of these students, as well as the detection of attention deficit...

PURPOSE OF REVIEW: The aim of this study was to illuminate the extent of the bilateral central vestibular network from brainstem and cerebellum to subcortical and cortical areas and its interrelation to higher cortical functions such as spatial cognition and anxiety. RECENT FINDINGS: The conventional view that the main function of the vestibular system is the perception of self-motion and body orientation in space and the sensorimotor control of gaze and posture had to be developed further by a hierarchical organisation with bottom-up and top-down interconnections...

REVIEW
Frank Fitoussi, Pauline Lallemant Dudek
Management of the upper limb in children with cerebral palsy is often complex and must be carried out by a team experienced in this field. Several clinical parameters must be taken into consideration, such as higher functions, visual problems, overall upper limb function, motor control, sensitivity, presence of hemineglect or synkinesis, limb position at rest and during walking. And last but not least, a complete analysis of the upper limb is required. It is only after this exhaustive assessment-which often includes occupational therapy, physiotherapy and in some cases, video and electromyography evaluations-that a treatment indication can be discussed with the patient's family...

We present a case of ultra-early symptomatic fish-mouth type stenosis (FMTS) of a Surpass Evolve flow diverter stent (SE-FDS) occurring within 24 h after deployment for the treatment of multiple unruptured right siphon aneurysms in a 44-year-old patient. The patient developed left hemiplegia and hemineglect, and was treated with mechanical thrombectomy (MT) and Tirofiban infusion. This is the first report of an ultra-early FMTS with a SE-FDS and its mechanism is discussed in the light of available data in the literature...

Hemispheric asymmetry is a fundamental principle in the functional architecture of the brain. It plays an important role in attention research where right hemisphere dominance is core to many attention theories. Lesion studies seem to confirm such hemispheric dominance with patients being more likely to develop left hemineglect after right hemispheric stroke than vice versa. However, the underlying concept of hemispheric dominance is still not entirely clear. Brain stimulation studies using transcranial magnetic stimulation (TMS) might be able to illuminate this concept...

INTRODUCTION: One of the strangest kinds of misperceptions of the body is "Body Integrity Dysphoria" (BID), formerly named as "Body Identity Integrity Disorder" (BIID). The affected people have the feeling that a limb is not part of their body. They can feel it, they can use it, they can move it, but they cannot get along with the fact that it is a part of their own body. Most feel the need for an amputation of a leg, others of both legs, some want a palsy and use a wheelchair. Still discussed is whether other disablements such as blindness, dumbness, deafness or a desire to have an incontinency can be included in this diagnosis...

BACKGROUND: Large vessel occlusive (LVO) stroke causes severe disabilities and occurs in more than 37% of strokes. Reperfusion therapy is the gold standard of treatment. Studies proved that endovascular thrombectomy (EVT) is more beneficial and decreases mortality. This study aimed to evaluate the factor associated with LVO stroke in an Asian population and to develop the scores to predict LVO in a prehospital setting. The score will hugely contribute to the future of stroke care in prehospital settings in the aspect of transferal suspected LVO stroke patients to appropriate EVT-capable stroke centers...

Acute hypoglycemia may mimic acute ischemic stroke, but to our knowledge this has never been reported as transient hemineglect syndrome. We present a 60-year-old male with known diabetes mellitus who was brought to the hospital as a stroke alert. The patient had undetectable glucose levels upon arrival of emergency medical services (EMS), therefore hypertonic glucose was given. On our assessment in the emergency department (ED)he turned his head to the right side, looking to the right to answer questions when addressed on his left side...

We report the case of an 81-year-old woman who presented with a left hemineglect, a rightward gaze preference, and baseline disorientation. Her National Institutes of Health Stroke Score was 4. Her medical history was significant for dementia, osteoporosis, dyslipidemia, and a previous stroke. CT revealed a right-sided frontal lobe hemorrhage with surrounding edema and subarachnoid hemorrhage. Laboratory evaluation was significant for leukocytosis. The etiologies, clinical presentation, and diagnosis of this often devastating type of stroke are presented...

Background: Visual perception is a dynamic process of perceiving the environment through sensory input and transforming sensory input into meaningful concepts related to environmental visual knowledge. Many studies focusing on the role of visual perception after stroke have been published in various journals. However, a bibliometric analysis in the domain of visual perception after stroke is still lacking. This study aimed to deliver a visual analysis to analyze the global trends in research on the role of visual perception after stroke in the last 10 years...

Stroke frequently produces attentional dysfunctions including symptoms of hemispatial neglect, which is characterized by a breakdown of awareness for the contralesional hemispace. Recent studies with functional MRI (fMRI) suggest that hemineglect patients display abnormal intra - and interhemispheric functional connectivity. However, since stroke is a vascular disorder and fMRI signals remain sensitive to nonneuronal (i.e., vascular) coupling, more direct demonstrations of neural network dysfunction in hemispatial neglect are warranted...

Several cortical and sub-cortical regions in the right hemisphere, particularly in parietal and frontal lobe, but also in temporal lobe and thalamus, are part of neural networks critically implicated in spatial and attentional functions. Damage to different sites within these networks can cause hemispatial neglect. The aim of this study was to identify the neural substrates of different spatial processing components that are known to contribute to neglect symptoms. First, three different spatial tasks (visual search, bisection, and visual memory) were tested in 27 patients with focal right brain-damage...
