INTRODUCTION: Currently, none of the available multiple sclerosis (MS) disease-modifying medications has been shown to stop or reverse gait disability. Recently, the nabiximols has been tested for the treatment of spasticity and walking impairment in MS. Nabiximols (trade name Sativex) is an oromucosal spray formulation containing 1:1 fixed ratio of delta-9-tetrahydrocannabinol and cannabidiol derived from cloned Cannabis sativa L. plant. METHOD AND ANALYSIS: A single-center, prospective, parallel design, single-blind trial will be conducted at the IRCCS Neurolesi "Bonino-Pulejo" (Italy) involving MS patients affected by spasticity and undergoing a Robotic Rehabilitation training...

Olivier Walusinski
Yawning, laughing, and crying are normal physiological behaviors of humans in good health. As with all physiological behaviors, their deregulation can reveal disorders. Pathological yawning occurs in salvos of 10-20 successive yawns, and the number of yawns per day can exceed one hundred. After listing the functional etiologies, we will give the clinical keys for differentiating the most serious causes: iatrogenic, tumors, strokes, amyotrophic lateral sclerosis, and intracranial hypertension. Sudden, uncontrollable episodes of emotional display involving pathological laughing and crying (PLC) may be encountered in various neurological diseases: amyotrophic lateral sclerosis, multiple system atrophy (cerebellar), cerebrovascular disease, traumatic brain injuries, mass lesions in the cerebellopontine junction, and epilepsy...

Background: Multiple sclerosis (MS) is a severe neurological disorder, characterized by demyelination of the central nervous system (CNS), and with a prevalence of greater than 2 million people worldwide. In terms of research in MS pathology, the cuprizone toxicity model is widely used. Here we investigated the contribution of genetic differences in response to cuprizone-induced demyelination in two genetically different mouse strains: CD1 and C57BL/6. Results: We demonstrate that exposure to a diet containing 0...

BACKGROUND: Multiple sclerosis (MS) is a chronic inflammatory demyelinating and neurodegenerative disease affecting the central nervous system. One of the basic medications for the treatment of a clinically isolated syndrome (CIS) or relapsing-remitting MS is interferon beta (INFβ). Although the exact mechanism of its effects is unknown, the medication has an anti-inflammatory and immunomodulatory effect. The goal of this study was to determine the characters which are affected in patients treated with INFβ...

BACKGROUND: Published data suggested high dose biotin improved patients with progressive MS. We wished to determine benefits and side effects of administering daily high dose biotin to patients with progressive multiple sclerosis in a large MS specialty clinic. METHODS: Forty-three patients with progressive multiple scleroses were prescribed pharmaceutical grade biotin as a single daily dose of 300mg/day. Brain MRIs were performed at baseline and after one year on biotin...

Experimental autoimmune encephalomyelitis (EAE) induced by self-myelin antigen is a widely used multiple sclerosis (MS) model for preclinical studies of new therapeutics and potential pathogenesis. By comparison with rodent EAE models, EAE models in primates are more similar to MS. Some groups have developed EAE models in primates by using common marmoset (Callithrix jacchus). However, this model has some limitations. EAE in cynomolgus monkey (Macaque fasciculrais) could overcome these limitations. In this study, EAE was induced in cynomolgus monkey by immunizing with the recombinant human myelin oligodendrocyte glycoprotein extracellular domain (1-125) (rhMOG1-125) and a synthetic peptide, representing peptide 34-56 of human myelin oligodendrocyte glycoprotein (MOG34-56) in complete Freund's adjuvant (CFA) and in combination with intravenous injection of pertussis toxin, and subsequent booster immunizations with the same dose of antigen in incomplete Freund's adjuvant (IFA) until the animals developed clinically significant EAE (score≥2)...

Multiple sclerosis (MS) is an autoimmune-inflammatory neurodegenerative disease that is often accompanied by a debilitating neuropathic pain. Disease-modifying agents slow the progression of MS and prevent relapses, yet it remains unclear if they yield analgesia. We explored the analgesic potential of fingolimod (FTY720), an agonist/functional antagonist at the sphingosine-1-phosphate receptor 1 (S1PR1), because it reduces hyperalgesia in models of peripheral inflammatory and neuropathic pain. We used a myelin oligodendrocyte glycoprotein 35-55 (MOG35-55) mouse model of experimental autoimmune encephalomyelitis (EAE), modified to avoid frank paralysis and thus allow for assessment of withdrawal behaviors to somatosensory stimuli...

Trigeminal nerve disorder is an important neurological sign that is often seen with multiple sclerosis (MS). We investigated eye movements in three MS patients with trigeminal disorder due to pontine lesions near the trigeminal root entry zone (REZ). Upbeat nystagmus was observed in all MS patients with trigeminal REZ lesions. We conjecture that trigeminal nerve disorder and upbeat nystagmus appeared due to simultaneous damage to both the trigeminal nerve and the vestibulo-ocular reflex pathway. If upbeat nystagmus appears in MS patients exhibiting a trigeminal nerve disorder, such as trigeminal neuralgia, and paralysis, pontine lesions near the trigeminal REZ should be considered...

Multiple sclerosis (MS) is a neurological disease characterized by focal lesions and morphological changes in the brain captured on magnetic resonance (MR) images. However, extraction of the corresponding imaging markers requires accurate segmentation of normal-appearing brain structures (NABS) and the lesions in MR images. On MR images of healthy brains, the NABS can be accurately captured by MR intensity mixture models, which, in combination with regularization techniques, such as in Markov random field (MRF) models, are known to give reliable NABS segmentation...

Importance: Antibodies to myelin oligodendrocyte glycoprotein IgG (MOG-IgG) are increasingly detected in patients with non-multiple sclerosis-related demyelination, some of whom manifest a neuromyelitis optica (NMO) phenotype. Cortical involvement, encephalopathy, and seizures are rare in aquaporin 4 antibody (AQP4-IgG)-related NMO in the white European population. However, the authors encountered several patients with seizures associated with MOG-IgG disease. Objective: To compare incidence of seizures and encephalitis-like presentation, or both between AQP4-IgG-positive and MOG-IgG-positive patients...

BACKGROUND: Multiple sclerosis (MS) is a severe and common autoimmune disorder of the central nervous system. Despite the availability of several novel treatment options, the disease is still poorly controlled, since the pathophysiological mechanisms are not fully understood. METHODS: We tested the role of the acid sphingomyelinase/ceramide system in a model of MS, i.e. experimental autoimmune encephalomyelitis (EAE). Mice were immunized with myelin-oligodendrocyte glycoprotein and the development of the disease was analyzed by histology, immunological tests and clinical assessment in wildtype and acid sphingomyelinase (Asm)-deficient mice...

Tuberous sclerosis complex (TSC) 1 or TSC2 is mutated in most TSC patients. TSC2 mutations are more frequently associated with worse outcomes, earlier age at seizure onset, more severe intellectual disability, and higher tuber load than TSC1. The degree of white matter involvement is thought to be associated with the severity of neurological impairment. At present, genotype-phenotype correlations and relationship between tuber burden and neurological disability in TSC are debatable. We presented a 43-year-old patient with TSC2 mutation, whose symptom was only incomplete quadrantic visual field deficit in spite of multiple brain tubers...

BACKGROUND: Respiratory disorders in multiple sclerosis (MS) are an important issue. They can occur early during the course of the disease, are associated with the neurological impairment, and can lead to pneumonia and respiratory failure, which are the main causes of death in advanced MS. Prevailing impaired expiratory muscles and cough abilities has been demonstrated in this population and might constitute a specific target for rehabilitation interventions. However, international guidelines lack recommendations regarding respiratory rehabilitation in MS...

Patients with multiple sclerosis (MS) are often nonadherent to their disease modifying therapy (DMT). While recent studies demonstrate enhanced DMT adherence following intervention grounded in motivational interviewing (MI), little is known about how to address DMT reinitiation among MS patients who have prematurely discontinued DMT against medical advice and do not intend to reinitiate. We examined baseline predictors of DMT reinitiation among patients with MS who discontinued medications against medical advice following a telephone-based MI and Cognitive Behavioral Therapy (MI-CBT) intervention...

Neurological diseases have become an obvious challenge due to insufficient therapeutic intervention. Therefore, novel drugs for various neurological disorders are in desperate need. Recently, compelling evidence has demonstrated that chemokine receptor CXCR3, which is a G protein-coupled receptor in the CXC chemokine receptor family, may play a pivotal role in the development of neurological diseases. The expression level of CXCR3 in T cells was significantly elevated in several neurological diseases, suggesting a potential therapeutic role of CXCR3 antagonists...

The nocebo effect, the inverse of the placebo effect, is a well-established phenomenon, yet under-appreciated. It refers to nonpharmacological, harmful, or undesirable effects occurring after active or inactive therapy. The frequency of adverse events can dramatically increase by informing patients about the possible side effects of the treatment, and by negative expectations on the part of the patient. Patients who were told that they might experience sexual side effects after treatment with β-blocker drugs reported these symptoms between three and four times more often than patients in a control group who were not informed about these symptoms...

It is widely recognized that myelination of axons greatly enhances the speed of signal transmission. An exciting new finding is the dynamic communication between axons and their myelin-forming oligodendrocytes, including activity-dependent signalling from axon to myelin. The oligodendrocyte-myelin complex may in turn respond by providing metabolic support or alter subtle myelin properties to modulate action potential propagation. In this Opinion, we discuss what is known regarding the molecular physiology of this novel, synapse-like communication and speculate on potential roles in disease states including multiple sclerosis, schizophrenia and Alzheimer disease...

Neuromodulation, or the utilization of advanced technology for targeted electrical or chemical neuronal stimulation or inhibition, has been expanding in several neurological subspecialties. In the past decades, immune-modulating therapy has been the main focus of multiple sclerosis (MS) research with little attention to neuromodulation. However, with the recent advances in disease-modifying therapies, it is time to shift the focus of MS research to neuromodulation and restoration of function as with other neurological subspecialties...
