Brain-Computer interfaces for communication: preferences of individuals with locked-in syndrome, caregivers and researchers
CONCLUSIONS: Disagreements were clear between stakeholders regarding which mental strategies users prefer to use and when they would like to be informed about cBCIs. To move forward in the development and clinical implementation of cBCIs, it will be necessary to align the research agendas with the needs of the end-users and caregivers.IMPLICATIONS FOR REHABILITATIONBrain-Computer Interfaces may offer people with severe motor impairment a brain-based and muscle-independent approach to control communication-technology.

The clinical and cognitive spectrum of locked-in syndrome: 1-year follow-up of 100 patients
AbstractIn patients with locked-in syndrome (LIS), it is not known exactly to what extent cognitive functions are preserved and it is not known exactly how much it has improved. We aimed to examine the clinical and cognitive features of LIS 1 year after stroke. One hundred patients with locked-in syndrome (LIS) were recruited between January 2008 and May 2019 among 8200 patients with ischemic stroke. Patients were classified into two groups as single pontine infarcts (n = 72), and pontine plus multiple ischemic lesions (PMIL) (n = 28). Since the patients had limited motor and verbal response, the cognitive status o...

Neurophysiological aspects of the completely locked-in syndrome in patients with advanced amyotrophic lateral sclerosis
CONCLUSIONS: The heterogeneity of the results underscores the fact that no single neurophysiological index is available to assess psychophysiological states in unresponsive ALS patients in CLIS. This caveat may also be valid for the assessment of cognitive processes; a functioning BCI can be the solution.SIGNIFICANCE: Most of the studies of the neurophysiology of ALS patients focused on the early stage of the disease, and there are very few studies on the late stage when patients are completely paralyzed with no means of communication (i.e., CLIS). This study provides quantitative metrics of different neurophysiological as...

A clinical characteristic analysis of five cases of rare bilateral cerebral peduncular infarction (BCPI) with the 'Mickey Mouse ears' sign.
Conclusions: BCPI is a very rare stroke disease and its main clinical manifestations are locked-in syndrome and persistent vegetative states. However, the obtained imaging features on the brain-MRI of patients diagnosed with BCPI with the 'Mickey Mouse ears' sign can predict a bad prognosis.

Case series: Hyperdense basilar artery identified on unenhanced head CT in three cases of pediatric basilar artery occlusion
Acute basilar artery occlusion (BAO) is an easily missed, potentially devastating type of ischemic stroke. Children with BAO can present with a range of clinical symptoms, from headache, dizziness, nausea and/or vomiting [1-3] to profound alterations of consciousness, including locked-in syndrome and coma [2]. Typically in children with BAO, only an unenhanced head Computed Tomography (CT) is initially performed. When an obvious finding is not identified, such as intracranial hemorrhage, the unenhanced CT is rarely carefully further scrutinized by emergency physicians.

"Re-identifying yourself": a qualitative study of veteran views on implantable BCI for mobility and communication in ALS.
CONCLUSION: The interest in BCI and views on ethical issues raised by BCI is moderated by the experience of living with ALS. The findings from this study can help guide the development of implantable BCI technology for persons with ALS. Implications for rehabilitation Loved ones will play crucial roles in helping patients think through the possible benefits and burdens of getting a BCI device. Providers should consider how the ideal timing for getting an implantable BCI device will vary based on the priorities of persons with ALS and their disease stage. Concerns about social stigma, burden of adjustment, and the desire to...

Recurrent Vertebrobasilar Strokes Associated With Acute Posterior Multifocal Placoid Pigment Epitheliopathy (APMPPE)
Conclusions:
This case illustrates the importance of careful evaluation and high clinical suspicion for this entity when dealing with patients with new-onset headache or stroke associated with visual impairment. Proper ophthalmologic evaluation is important so that adequate therapy is established. (Source: The Neurologist)

Functional Near-Infrared Spectroscopy in the Study of Speech and Language Impairment Across the Life Span: A Systematic Review.
Conclusions Though it is not without inherent challenges, fNIRS may have advantages over other neuroimaging techniques in the areas of speech and language impairment. fNIRS has clinical applications that may lead to improved early and differential diagnosis, increase our understanding of response to treatment, improve neuroprosthetic functioning, and advance neurofeedback.

Basilar artery thrombosis during sexual intercourse
We report a young woman with a life-threatening basilar artery thrombosis during sexual intercourse, with a resulting locked-in syndrome. The positive high intensity transient signals (HITS) diagnosis showed a right-to-left shunt and is in line with paradoxic embolism. The molecular genetics revealed a homozygosity 4G/4G in the region PAI1, -675 (promoter polymorphism) as a risk factor for ischemic stroke. Sexual intercourse is a possible, albeit unusual stroke cause, especially in young people. (Source: Journal of Clinical Neuroscience)

Topographic Somatosensory Imagery for Real-Time fMRI Brain-Computer Interfacing
This study demonstrates that body part-specific somatosensory imagery differentially activates somatosensory cortex in a topographically specific manner; evidence which was surprisingly still lacking in the literature. It also offers proof of concept for a novel somatosensory imagery-based fMRI-BCI control strategy, with particularly high potential for visually and motor-impaired patients. The strategy could also be transferred to lower MRI field strengths and to mobile functional near-infrared spectroscopy. Finally, given that communication BCIs provide the BCI user with a form of feedback based on their brain signals and...
