Pseudobulbar affect (PBA) is a socially debilitating condition that primarily affects people with neurologic diseases, such as Alzheimer's disease or multiple sclerosis. This condition is characterized by uncontrolled, exaggerated expressions of laughing or crying-often when the situation does not warrant this behavior. Although the true prevalence of PBA is surprisingly high, this condition remains widely misdiagnosed and underdiagnosed. While its exact etiology is unknown, PBA likely results from disruptions in the brain structures and/or neurotransmitters that regulate emotions...

BACKGROUND: There is no standard palliative care outcome measure for people with progressive long term neurological conditions (LTNC). This study aims to determine the psychometric properties of a new 8-item palliative care outcome scale of symptom burden (IPOS Neuro-S8) in this population. DATA AND METHODS: Data were merged from a Phase II palliative care intervention study in multiple sclerosis (MS) and a longitudinal observational study in idiopathic Parkinson's disease (IPD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP)...

The prevalence of disability due to neurological conditions is escalating worldwide. Neurological disorders have significant disability-burden with long-term functional and psychosocial issues, requiring specialized rehabilitation services for comprehensive management, especially treatments tapping into brain recovery 'neuroplastic' processes. Neurorehabilitation is interdisciplinary and cross-sectorial, requiring coordinated effort of diverse sectors, professions, patients and community to manage complex condition-related disability...

MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression. Recently, we have shown that informative miRNA data can be derived from archived formalin-fixed paraffin-embedded (FFPE) samples from postmortem cases of amyotrophic lateral sclerosis and normal controls. miRNA analysis has now been performed on FFPE samples from affected brain regions in patients with multiple system atrophy (MSA) and the same areas in neurologically normal controls. We evaluated 50 samples from patients with MSA (n=13) and controls (n=13)...

OBJECTIVES: Although many neurologists are reluctant to use natalizumab in MS (multiple sclerosis) given the increased risk for PML (progressive multifocal leukoencephalopathy), trust was regained with the introduction of JCV antibody titres as a potent disease-modifying therapy. Literature shows that in patients with a negative JCV serology, the risk of PML is virtually non-existent. Unfortunately, seroconversion causes concern amongst many neurologists. Furthermore, when patients seroconvert, it is still unclear what the risk is of passing the important threshold of 1...

Using the term of progressive multiple sclerosis (PMS), we considered a combined population of persons with secondary progressive MS (SPMS) and primary progressive MS (PPMS). These forms of MS cannot be challenged with efficacy by the licensed therapy. In the last years, several measures of risk estimation were developed for predicting clinical course in MS, but none is specific for the PMS forms. Personalized medicine is a therapeutic approach, based on identifying what might be the best therapy for an individual patient, taking into account the risk profile...

We report a unique case of neurological deficit from late onset multiple sclerosis (MS), in a 65-year-old woman, after stereotactic radiosurgery (SRS) for trigeminal neuralgia (TN). At 3.5months post-SRS for TN, the patient developed ataxia and left leg paraesthesiae and brain MRI showed altered signal and enhancement in the vicinity of the right trigeminal root entry zone (REZ). The symptoms remitted following treatment with intravenous methylprednisolone, however, 10months post-SRS, the patient developed gait ataxia and left lower limb weakness...

BACKGROUND: Multiple sclerosis (MS) is a neurological disorder that causes significantly reduced ability to work, and the Expanded Disability Status Scale (EDSS) is one of the main predictors for reduced work ability. OBJECTIVES: To investigate how work requirements, flexible work conditions and disease-modifying drugs (DMDs) influence the work ability in relation to different EDSS grades in two MS populations. METHODS: Work ability was studied in two MS populations: one in the southern and one in the northern part of Sweden, both demographically similar...

BACKGROUND AND PURPOSE: The increasing use of the emergency department MR imaging scanner at our institution raises questions about its added value to certain patient groups. We hypothesized that the use of emergency department MR imaging for identifying active demyelination in MS patients presenting with new neurologic symptoms would be of low yield. MATERIALS AND METHODS: Electronic medical records were reviewed for patients with MS who had emergency department MR imaging scans for a suspected MS exacerbation between March 1, 2014, and March 1, 2016...

Multiple sclerosis (MS) is a chronic neurological disorder that affects the central nervous system (CNS), and results in CNS inflammation and damage to myelin. In this study, we examined the possible synergistic effects of C16, angiopoietin-1 (Ang-1) and regeneration gene protein 2 (Reg-2) in alleviating inflammation in an acute experimental autoimmune encephalomyelitis (EAE) model. We employed multiple histological, morphological and iconographic assays to examine the effect of those drugs on disease onset, clinical scores and behavioral deficits...

Multiple sclerosis (MS) is an autoimmune demyelinating disorder of the central nervous system. Only a few biomarkers are available in MS clinical practice, such as cerebrospinal fluid oligoclonal bands and immunoglobulin index, serum anti-aquaporin 4 antibodies, and serum anti-John Cunningham virus antibodies. Thus, there is a significant unmet need for biomarkers to assess prognosis, response to therapy, or potential treatment complications. Here we describe emerging biomarkers that are in development, focusing on those from peripheral blood...

Balance impairment is common in people with multiple sclerosis (PwMS) and frequently impacts quality of life by decreasing mobility and increasing the risk of falling. However, there are only scarce data examining the contribution of specific neurological functional systems on balance measures in MS. Therefore, the primary aim of our study was to examine the differences in posturography parameters and fall incidence according to the pyramidal, cerebellar and sensory systems functional systems in PwMS. The study included 342 PwMS, 211 women and mean disease duration of 8...

PURPOSE OF REVIEW: This article focuses on neuroimaging in multiple sclerosis (MS), the most common central nervous system (CNS) demyelinating disorder encountered by practicing neurologists. Less common adult demyelinating disorders and incidental subclinical white matter abnormalities that are often considered in the differential diagnosis of MS are also reviewed. RECENT FINDINGS: Advancements in neuroimaging techniques, eg, the application of ultrahigh-field MRI, are rapidly expanding the use of neuroimaging in CNS demyelinating disorders...

The serine/threonine kinase mechanistic target of rapamycin (mTOR) is an important sensor of the cellular energy condition which, at the same time, represents a kind of master switch between anabolic and catabolic cellular processes. Tuberous sclerosis complex (TSC) is a genetic disease which is considered to be a prototype of a dysregulated mTOR signaling pathway. The dysregulated mTOR pathway in TSC leads to characteristic structural and physiologic abnormalities in multiple organs. In this review we focus on the pharmacological properties of mTOR inhibitors and clinical investigations of mTOR inhibitors for two important neurological TSC manifestations: subependymal giant cell astrocytomas (SEGAs) and epilepsy...

BACKGROUND: Dimethyl fumarate (DMF), working via its metabolite monomethylfumarate (MMF), acts as a potent antioxidant and immunomodulator in animal models of neurologic disease and in patients with multiple sclerosis. These properties and their translational potential led us to investigate whether DMF/MMF could also protect at-risk and/or dying neurons in models of ischemic stroke in vitro and in vivo. Although the antioxidant effects have been partially addressed, the benefits of DMF immunomodulation after ischemic stroke still need to be explored...

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS). Many believe autoimmune pathogenesis plays a key role in MS, but its target(s) remains elusive. A recent study detected autoantibodies against KIR4.1, an ATP-sensitive, inward rectifier potassium channel, in nearly half of the MS patients examined. KIR4.1 channels are expressed in astrocytes. Together with aquaporin 4 (AQP4) water channels, they regulate astrocytic functions vital for myelination. Autoantibodies against AQP4 have been established as a key biomarker for neuromyelitis optica (NMO) and contributed to diagnostic and treatment strategy adjustments...

In the current study, we conducted a quantitative in-depth proteome and deglycoproteome analysis of cerebrospinal fluid (CSF) from relapsing-remitting multiple sclerosis (RRMS) and neurological controls using mass spectrometry and pathway analysis. More than 2000 proteins and 1700 deglycopeptides were quantified, with 484 proteins and 180 deglycopeptides significantly changed between pools of RRMS and pools of controls. Approximately 300 of the significantly changed proteins were assigned to various biological processes, including inflammation, extracellular matrix organization, cell adhesion, immune response and neuron development...

Extracellular matrix metalloproteinase inducer (EMMPRIN, CD147) is an inducer of matrix metalloproteinases and has roles in leukocyte activation and migration. We reported previously that in MS and its animal model, experimental autoimmune encephalomyelitis, cell surface-associated EMMPRIN was significantly elevated in leukocytes around inflammatory perivascular cuffs in the CNS. In this study we report that activated T-cells can secrete soluble form of EMMPRIN (sEMMPRIN) upon activation. As sEMMPRIN is also present in biological fluids, we determined whether sEMMPRIN is altered in the CSF and sera of MS subjects...

BACKGROUND AIMS: There is a critical unmet need to develop regenerative therapies for the demyelinating disease multiple sclerosis (MS). We previously characterized the immunoregulatory and trophic properties of neural progenitors derived from bone marrow mesenchymal stromal cells (MSC-NPs) and established that cells derived from MS and non-MS patients alike were therapeutically viable. In an experimental model of MS, intrathecal MSC-NP injection resulted in disease amelioration with decreased T-cell infiltration, and less severe lesion pathology associated with recruitment of resident progenitors to inflammatory sites...

Vitamin D deficiency is an environmental risk factor for MS, a Th17 cell-mediated autoimmune disease that results in demyelination in the CNS. Therefore, we aimed to evaluate the ability of in vitro 1,25(OH)2D in modulating different Th17 cell subsets in MS patients in remission phase. In the present study, the production of Th17-related cytokines (IL-1β, IL-6, IL-17, IL-22), as well as GM-CSF, was significantly higher in cell cultures from MS patients than in healthy subjects (HS). The 1,25(OH)2D reduced all pro-inflammatory cytokines essayed, mainly those released from HS cell cultures...
