Effects of Cerebellar Transcranial Direct Current Stimulation in Patients with Stroke: a Systematic Review
CONCLUSIONS: ctDCS appears to improve poststroke language and motor dysfunction (particularly gait). However, the evidence for these results was insufficient, and the quality of the relevant studies was low. ctDCS stimulation parameters and individual factors of participants may affect the therapeutic effect of ctDCS. Researchers need to take a more regulated approach in the future to conduct studies with large sample sizes. Overall, ctDCS remains a promising stroke intervention technique that could be used in the future.PMID:36028789 | DOI:10.1007/s12311-022-01464-7

Transcranial Direct-Current Stimulation and Behavioral Training, a Promising Tool for a Tailor-Made Post-stroke Aphasia Rehabilitation: A Review
Aphasia is an acquired language disorder resulting from damage to portions of the brain which are responsible for language comprehension and formulation. This disorder can involve different levels of language processing with impairments in both oral and written comprehension and production. Over the last years, different rehabilitation and therapeutic interventions have been developed, especially non-invasive brain stimulation (NIBS) techniques. One of the most used NIBS techniques in aphasia rehabilitation is the Transcranial Direct-Current Stimulation (tDCS). It has been proven to be effective in promoting a successful r...

Feasibility of Cerebellar Transcranial Direct Current Stimulation to Facilitate Goal-Directed Weight Shifting in Chronic Post-Stroke Hemiplegics
The objectives of this work were to (1) present a refined Virtual Reality (VR)-based balance training platform (VBaT) that can measure Center of Pressure (CoP) and (2) carry out a study to understand the implication of ctDCS stimulating the dentate nuclei (PhaseD) and lobules VII-IX (PhaseL) on the postural control of chronic stroke patients when they interacted with VBaT. Also, we investigated whether hemiplegic patients (with intact cerebellum) having Basal Ganglia (BG) infarction had any differential abilities to correct postural sway from those with no BG infarction (while shifting weight to the Affected side). Results...

Associations Between Two Single-Nucleotide Polymorphisms in NINJ2 Gene and Risk of Psychiatric Disorders
AbstractNINJ2 encodes a transmembrane protein that contributes in neurodevelopment and regeneration of neurons. Single-nucleotide polymorphisms (SNPs) within this gene have been associated with Alzheimer ’s disease, ischemic stroke, and multiple sclerosis. The rs11833579 and rs3809263 SNPs have been associated with risk of ischemic stroke in Iranian population. While theNINJ2 rs12425791 has been with risk of ischemic stroke in East Asian population, the rs11833579 has not been associated with this condition either in East Asian population or Chinese Han population. In the current project, we genotyped rs11833579 and rs38...

Modulating Applied Task Performance via Transcranial Electrical Stimulation
Conclusion tES may prove valuable for modulating applied task performance, though research in this area warrants careful consideration of several individual-, context-, and task-related factors that may predict the robustness and directionality of tES effects. Whereas most applied research with tES has administered tDCS, tACS and tRNS have also shown potential to modulate cortical activity and behavior. Even in highly applied and dynamic tasks, such as navigation and driving, tES appears to carry some performance benefits. This is compelling because as tES is slowly incorporated into highly complex real-world environments...

Exploring Training Effect in 42 Human Subjects Using a Non-invasive Sensorimotor Rhythm Based Online BCI
Conclusion In this study, we analyzed a pooled dataset consisting of 42 subjects’ three BCI training sessions. The behavioral performance results showed that there was a significant increase of BCI PVC accuracy (p = 0.004) and a marginal significant improvement of ITR (p = 0.05) in the third training session compared to the first session. No other significant difference of behavioral measures such as group average abort rate or feedback duration was found across the training sessions. Further analysis on the group average R2 value indicated that there was a significant difference of the R2 value on the first traini...

Functional MRI of Letter Cancellation Task Performance in Older Adults
Conclusion The present work is the first to identify neural correlates of the LCT using fMRI and tablet technology in a healthy aging population. Across all ages, the activation was found to be bilateral, including in the cerebellum, superior temporal lobe, precentral gyrus, frontal gyrus, and various occipital and parietal areas. With increasing age, performance generally decreased and brain activity was reduced in the supplementary motor area, middle and inferior frontal gyrus, middle occipital gyrus, putamen and cerebellum. Better LCT performance was correlated with increased activity in the middle frontal gyrus, and r...

Chapter Seventeen - Nocebo Responses in Brain Diseases: A Systematic Review of the Current Literature
Publication date: 2018Source: International Review of Neurobiology, Volume 139Author(s): Panagiotis Zis, Dimos-Dimitrios MitsikostasAbstractPlacebo is an intervention with no therapeutic effect that is used as a control in randomized controlled trials (RCTs). Placebo effects and responses can produce a beneficial effect that cannot be attributed to the properties of the intervention itself, since it is usually inactive, and should, therefore, be due to the patient's expectations about treatment (placebo effects), or confounding factors such as natural history, co-interventions, biases, among other co-factors (placebo respo...

Atrial Fibrillation and Injected Aripiprazole: A Case Report
Conclusion In summary, although it is not possible to exclude confounding factors, the timing and dose-dependent effect of aripiprazole administration in our patient suggests an association between an initial intramuscular injection of long-acting aripiprazole and new onset of AF. This observation calls for clinical vigilance, not only in patients with additional risk factors for stroke but also in younger patients who might have predisposing factors for arrhythmias.

CNS Summit 2017 Abstracts of Poster Presentations
Conclusion: This novel technology discriminates and quantifies subtle differences in behavior and neurological impairments in subjects afflicted with neurological injury/disease. KINARM assessments can be incorporated into multi-center trials (e.g., monitoring stroke motor recovery: NCT02928393). Further studies will determine if KINARM Labs can demonstrate a clinical effect with fewer subjects over a shorter trial period. Disclosures/funding: Dr. Stephen Scott is the inventor of KINARM and CSO of BKIN Technologies.   Multiplexed mass spectrometry assay identifies neurodegeneration biomarkers in CSF Presenter: Chelsky...

Permanent Cerebellar Degeneration After Acute Hyperthermia with Non-toxic Lithium Levels: a Case Report and Review of Literature.
Abstract This was a study of a 33-year-old man with bipolar disorder treated with lithium who developed cerebellar atrophy after an event of extreme hyperthermia. Unlike previously reported cases of acute cerebellar atrophy after heat stroke, neuroleptic syndrome or lithium toxicity, this case was characterized by a chronic cerebellar atrophy that developed after sepsis-induced hyperthermia in the setting of non-toxic lithium levels. Unique to this case also was the early finding of cerebellar atrophy on MRI 2 weeks after the episode of hyperthermia, long-term neurotoxicity after the novo lithium therapy, and lon...
