Modafinil for the Improvement of Patient Outcomes Following Traumatic Brain Injury
Conclusion. Modafinil is a central nervous system stimulant with well-established effectiveness in the treatment of narcolepsy and shift-work sleep disorder. There is conflicting evidence about the benefits of modafinil in the treatment of fatigue and EDS secondary to TBI. One randomized, controlled study states that modafinil does not significantly improve patient wakefulness, while another concludes that modafinil corrects EDS but not fatigue. An observational study provides evidence that modafinil increases alertness in fatigued patients with past medical history of brainstem diencephalic stroke or multiple sclerosis. ...

Administration of Uric Acid in the Emergency Treatment of Acute Ischemic Stroke
Abstract Oxidative stress is one of the main mechanisms implicated in the pathophysiology of inflammatory and neurodegenerative diseases of the central nervous system (CNS). Uric acid (UA) is the end product of purine catabolism in humans, and it is the main endogenous antioxidant in blood. Low circulating UA levels have been associated with an increased prevalence and worse clinical course of several neurodegenerative and inflammatory diseases of the CNS, including Parkinson’s disease and multiple sclerosis. Moreover, the exogenous administration of UA exerts robust neuroprotective properties in experimental m...

Sphingosine ‐1‐phosphate receptor modulators in stroke treatment
AbstractSphingosine-1-phosphate (S1P) is a bioactive lysophospholipid that can influence a broad range of biological processes through its binding to five distinct G protein-coupled receptors. S1P receptor modulators are a new group of immunosuppressive agents currently used in the immunotherapy of multiple sclerosis. Inflammation following stroke may exacerbate injury. Given that S1P signaling is linked to multiple immune processes, therapies targeting the S1P axis may be suitable for treating stroke. In this review, we outline S1P metabolism and S1P receptors, discuss the mechanisms of action of S1P receptor modulators i...

The subpopulation of microglia expressing functional muscarinic acetylcholine receptors expands in stroke and Alzheimer's disease.
Abstract Microglia undergo a process of activation in pathology which is controlled by many factors including neurotransmitters. We found that a subpopulation (11 %) of freshly isolated adult microglia respond to the muscarinic acetylcholine receptor agonist carbachol with a Ca(2+) increase and a subpopulation of similar size (16 %) was observed by FACS analysis using an antibody against the M3 receptor subtype. The carbachol-sensitive population increased in microglia/brain macrophages isolated from tissue of mouse models for stroke (60 %) and Alzheimer's disease (25 %), but not for glioma and multiple sclero...

Roles of NG2-glia in ischemic stroke.
Abstract Recent studies have shown that a widely distributed class of glial cells, termed NG2-glia, engages in rapid signaling with surrounding neurons through direct synaptic contacts in the developing and mature central nervous system (CNS). This unique glial cell group has a typical function of proliferating and differentiating into oligodendrocytes during early development of the brain, which is crucial to axon myelin formation. Therefore, NG2-glia are also called oligodendrocyte precursor cells (OPCs). In vitro and in vivo studies reveal that NG2-glia expressing receptors and ion channels demonstrate function...

Instrumental Assessment of Stair Ascent in People With Multiple Sclerosis, Stroke, and Parkinson’s Disease: A Wearable-Sensor-Based Approach
Stair ascent is a challenging daily-life activity highly related to independence. This task is usually assessed with clinical scales suffering from partial subjectivity and limited detail in evaluating different task aspects. In this paper, we instrumented the assessment of stair ascent in people with multiple sclerosis (MS), stroke (ST), and Parkinson’s disease (PD) to analyze the validity of the proposed quantitative indexes and characterize subjects’ performances. Participants climbed 10 steps wearing a magneto-inertial sensor [magneto-inertial measurement unit (MIMU)] at sternum level. Gait pattern featur...

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...

The Metabolic Cost of Exercising With a Robotic Exoskeleton: A Comparison of Healthy and Neurologically Impaired People
While neuro-recovery is maximized through active engagement, it has been suggested that the use of robotic exoskeletons in neuro-rehabilitation provides passive therapy. Using oxygen consumption (VO2) as an indicator of energy expenditure, we investigated the metabolic requirements of completing exercises in a free-standing robotic exoskeleton, with 20 healthy and 12 neurologically impaired participants (six with stroke, and six with multiple sclerosis (MS)). Neurological participants were evaluated pre- and post- 12 weeks of twice weekly robotic therapy. Healthy participants were evaluated in, and out of, the exoskeleton....

Peculiarities of Neurological Disorders and Study Designs.
The objectives of treatments of neurodegenerative disorders include primary prevention, slowing or arrest of disease progression, and control of symptoms. Stroke is an acute clinical condition causing frequent disability and death, with only one approved treatment. There are many challenges to acute stroke clinical trials; among them, the very short therapeutic window and the issue of stroke heterogeneity. In this chapter, only the core elements of the study designs are outlined. KEY MESSAGES: The design of an RCT must be adapted to the basic characteristics of each clinical condition.

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...

Membrane‐type 1 metalloproteinase is upregulated in microglia/brain macrophages in neurodegenerative and neuroinflammatory diseases
We previously reported that glioma cells induce the expression of membrane‐type 1 metalloproteinase (MT1‐MMP or MMP‐14) in tumor‐associated microglia/macrophages and promote tumor growth, whereas MMP‐14 expression in microglia under physiological conditions is very low. Here, we show that the increase in MMP‐14 expression is also found in microglia/macrophages associated with neurodegenerative and neuroinflammatory pathologies in mouse models as well as in human biopsies or post‐mortem tissue. We found that microglial/macrophage MMP‐14 expression was upregulated in Alzheimer's disease tissue, in active lesi...

Erectile Dysfunction in Individuals with Neurologic Disability: A Hospital-based Cross-sectional Study
Conclusion: The occurence of erectile dysfunction is significantly more prevalent among neurologically disabled men, particularly those with lesions below S2–S4, than among men without neurologic disability. Considering the prevalence of erectile dysfunction among neurologically disabled men, sexual functioning should be regularly evaluated during acute and long-term rehabilitation, and any existing sexual dysfunction should be addressed in the treatment plan. Introduction Penile erection is a neurovascular event characterized by the dilation of arteries that cause the corpora cavernosa and corpora spongiosum of the peni...
