Memory problems are reported in 40%-60% of people with multiple sclerosis (MS). These problems affect independence and may limit the ability to benefit from rehabilitation. Our aim was to evaluate the effectiveness of NeuroPage for people with MS living in the community. A multicentre, single-blind, randomised controlled crossover trial was conducted. The intervention comprised the NeuroPage service, which sends reminder messages to mobile phones at pre-arranged times. In the control condition participants received "non-memory texts", that is, messages not aimed at providing a reminder; for example, supplying news headlines or sport updates...

BACKGROUND: To date, although great effort has been made to identify biomarkers of multiple sclerosis (MS), it remains unclear whether lysophosphatidic acid (LPA) can be used as a biomarker for MS. METHODS: This study compared the LPA levels in the serum and cerebrospinal fluid (CSF) in patients with MS in relapse versus in remission and investigated the change in LPA levels in MS patients in relapse after treatment. Forty-one patients with relapsing-remitting MS (RRMS) (21 patients in relapse and 20 patients in remission) and 21 patients with non-inflammatory, non-vascular neurological diseases as controls were included in this study...

Olfactory dysfunction is an early sign of neuroinflammation of the central nervous system (CNS). Microgliosis and astrogliosis are representative pathological changes that develop during neuroinflammation of CNS tissues. Autoimmune CNS inflammation, including human multiple sclerosis, is an occasional cause of olfactory disorders. We evaluated whether gliosis and olfactory dysfunction developed in animals with experimental autoimmune encephalomyelitis (EAE), a model of human multiple sclerosis. Neuroinflammatory lesions characterized by infiltration of inflammatory cells and microglial cell activation were occasionally found in the olfactory bulbs of EAE-affected rats...

Human herpesviruses (HVs) have developed ingenious mechanisms that enable them to traverse the defenses of the central nervous system (CNS). The ability of HVs to enter a state of latency, a defining characteristic of this viral family, allows them to persist in the human host indefinitely. As such, HVs represent the most frequently detected pathogens in the brain. Under constant immune pressure, these infections are largely asymptomatic in healthy hosts. However, many neurotropic HVs have been directly connected with CNS pathology in the context of other stressors and genetic risk factors...

OBJECTIVE: To validate a case definition of multiple sclerosis (MS) using health administrative data and to provide the first province-wide estimates of MS incidence and prevalence for Saskatchewan, Canada. METHODS: We used population-based health administrative data between January 1, 1996 and December 31, 2015 to identify individuals with MS using two potential case definitions: (1) ≥3 hospital, physician, or prescription claims (Marrie definition); (2) ≥1 hospitalization or ≥5 physician claims within 2 years (Canadian Chronic Disease Surveillance System [CCDSS] definition)...

The blood-brain barrier (BBB) has been a great hurdle for brain drug delivery. The BBB in healthy brain is a diffusion barrier essential for protecting normal brain function by impeding most compounds from transiting from the blood to the brain; only small molecules can cross the BBB. Under certain pathological conditions of diseases such as stroke, diabetes, seizures, multiple sclerosis, Parkinson's disease and Alzheimer disease, the BBB is disrupted. The objective of this review is to provide a broad overview on current strategies for brain drug delivery and related subjects from the past five years...

Most research on focal epilepsy focuses on mechanisms of seizure generation in the primary epileptic focus (EF). However, neurological deficits that are not directly linked to seizure activity and that may persist after focus removal are frequent. The recruitment of remote brain regions of an epileptic network (EN) is recognized as a possible cause, but a profound lack of experimental evidence exists concerning their recruitment and the type of pathological activities they exhibit.We studied the development of epileptic activities at the large-scale in male mice of the kainate model of unilateral temporal lobe epilepsy using high-density surface EEG and multiple-site intracortical recordings...

BACKGROUND: Metformin is a commonly used drug for the treatment of diabetes. Accumulating evidence suggests that it exerts anti-tumor effects in many cancers, including multiple myeloma (MM); however, the underlying molecular mechanisms have not been clearly elucidated. METHODS: The anti-myeloma effects of metformin were evaluated using human MM cell lines (RPMI8226 and U266) in vitro and in vivo NOD-SCID murine xenograft MM model. Cell viability was assessed with CCK8 and cell proliferation was measured by EdU incorporation assay...

BACKGROUND: Antibodies to human full-length myelin oligodendrocyte glycoprotein (MOG-IgG) as detected by new-generation cell-based assays have recently been described in patients presenting with acute demyelinating disease of the central nervous system, including patients previously diagnosed with multiple sclerosis (MS). However, only limited data are available on the relevance of MOG-IgG testing in patients with chronic progressive demyelinating disease. It is unclear if patients with primary progressive MS (PPMS) or secondary progressive MS (SPMS) should routinely be tested for MOG-IgG...

BACKGROUND: Low-education attainment is associated with worse cognitive performance in multiple sclerosis (MS) patients, and possibly with a lower cognitive reserve and/or increased inflammatory activity. Cognitive reserve refers to the capability of a source of intellectual enrichment in attenuating a negative effect of a disease-related factor; while the inflammatory activity is often related to T2-lesion load (T2-LL) increase. OBJECTIVE: To disentangle the effects of cognitive reserve and an increased T2-LL in MS-patients with low-education levels...

BACKGROUND: Optic neuritis in children is an uncommon disorder which usually occurs after a viral illness or vaccination and, less frequently, occurs as a manifestation of a demyelinating disorder. Pediatric optic neuritis usually is bilateral and presents with optic disc edema, recovers rapidly with steroid therapy, and generally has low conversion rate to multiple sclerosis or neuromyelitis optica spectrum disorder. We report the clinical features and treatment outcomes of pediatric optic neuritis in Indian population, for which little data are available...

OBJECTIVE: There is evidence that motor and cognitive impairments often co-occur in multiple sclerosis (MS). There is little research on influences of cognitive-motor coupling, particularly depressive symptoms. This study examined depressive symptoms as a moderator and/or confounder of cognitive-motor coupling in persons with MS. METHOD: The sample included 131 persons with MS who were allocated into elevated and nonelevated depressive symptom groups based on a cutoff score of 8 on the Hospital Anxiety Depression Scale...

Background: Both prolonged-release fampridine (PRF) and enabling active motor training (EAMT) are beneficial in multiple sclerosis (MS) patients. Their combined effect is, however, understudied. Objective: The objective of this paper is to determine if PRF augments the beneficial effect of EAMT in MS patients as opposed to placebo. Method: This is a pilot, randomized, placebo-controlled, double-blind 14-week study. Participants were randomly assigned to receive PRF 10 mg BID ( n  = 21) or placebo ( n  = 20)...

Alemtuzumab exerts its clinical efficacy by its specific pattern of depletion and repopulation of different immune cell subsets. Recently, single cases of multiple sclerosis patients who developed severe exacerbation after the first alemtuzumab application, accompanied by re-appearance of peripheral B cells, were reported. Here we present a case with underlying B cell-driven multiple sclerosis that impressively improves after alemtuzumab, although peripheral B cell repopulation took place. Our detailed clinical, histopathological, imaging and immunological data suggest that alemtuzumab can act as an effective rescue treatment in highly active B cell-driven and antibody/complement-mediated multiple sclerosis type II patients...

The causes of multiple sclerosis and amyotrophic lateral sclerosis have long remained elusive. A new category of pathogenic components, normally dormant within human genomes, has been identified: human endogenous retroviruses (HERVs). These represent ∼8% of the human genome, and environmental factors have reproducibly been shown to trigger their expression. The resulting production of envelope (Env) proteins from HERV-W and HERV-K appears to engage pathophysiological pathways leading to the pathognomonic features of MS and ALS, respectively...
