Pathogenesis and management of multiple sclerosis revisited.

BACKGROUND: Multiple sclerosis is an autoimmune chronic inflammatory disease characterized by selective destruction of myelin in the CNS neurons (including optic nerve). It was first described in the 19th century and remained elusive owing to the disease's unique relapsing and remitting course. The widespread and debilitating prevalence of multiple sclerosis (MS) has prompted the development of various treatment modalities for its effective management. METHODS AND OBJECTIVES: A literature review was conducted using the electronic databases PubMed and Google Scholar. The main objective of the …

Tau seeding in cases of multiple sclerosis.

Relapsing remitting multiple sclerosis (MS) is an inflammatory demyelinating disorder of the central nervous system that in many cases leads to progressive MS, a neurodegenerative disease. Progressive MS is untreatable and relentless, and its cause is unknown. Prior studies of MS have documented neuronal accumulation of phosphorylated tau protein, which characterizes another heterogeneous group of neurogenerative disorders, the tauopathies. Known causes of tauopathy are myriad, and include point mutations within the tau gene, amyloid beta accumulation, repeated head trauma, and viral infection…

The Multiple Sclerosis Prodrome: Evidence to Action.

A growing body of work points toward the existence of a clinically symptomatic prodromal phase in multiple sclerosis (MS) that might span 5-10 years or more. A prodrome is an early set of signs or symptoms predating the onset of classical disease, which in turn predates a definitive diagnosis. Evidence for a prodromal phase in MS could have major implications for prevention, earlier recognition and treatment, as well as an improved disease course or prognosis. This Perspective provides a succinct overview of the recent advances in our understanding of the MS prodrome and current key challenges…

Binocular Vision in Patients with Multiple Sclerosis.

PURPOSE: Oculomotor disorders have been reported in multiple sclerosis (MS) in up to 80% of cases. There have been studies evaluating binocular vision in several neurological diseases, but not in MS. Considering that a high percentage of eye-movement anomalies have been reported, the aim of this study was to analyze binocular vision in these subjects. METHODS: A total of 59 participants with MS - 21 with monocular optic neuritis, eleven with binocular optic neuritis, and 27 without optic neuritis - and 26 age-matched controls were enrolled. Binocular vision was analyzed using near point of co…

Diagnosis and Treatment of Multiple Sclerosis: A Review.

IMPORTANCE: Multiple sclerosis (MS) is an autoimmune-mediated neurodegenerative disease of the central nervous system characterized by inflammatory demyelination with axonal transection. MS affects an estimated 900 000 people in the US. MS typically presents in young adults (mean age of onset, 20-30 years) and can lead to physical disability, cognitive impairment, and decreased quality of life. This review summarizes current evidence regarding diagnosis and treatment of MS. OBSERVATIONS: MS typically presents in young adults aged 20 to 30 years with unilateral optic neuritis, partial myelitis…

Clinical presentation and diagnosis of multiple sclerosis.

The diagnosis of multiple sclerosis (MS) is through clinical assessment and supported by investigations. There is no single accurate and reliable diagnostic test. MS is a disease of young adults with a female predominance. There are characteristic clinical presentations based on the areas of the central nervous system involved, for example optic nerve, brainstem and spinal cord. The main pattern of MS at onset is relapsing-remitting with clinical attacks of neurological dysfunction lasting at least 24 hours. The differential diagnosis includes other inflammatory central nervous system disorder…

Atypical Multiple Sclerosis with Antibody to MOG.

CASE PRESENTATION: We report a case of a young female who had magnetic resonance imaging (MRI) brain lesions typical of multiple sclerosis (MS) with cerebrospinal fluid (CSF) oligoclonal bands (OCBs) and definite multiple sclerosis based on revised McDonald criteria; however, she also had atypical features of mild pleocytosis, brainstem and cerebellar peduncle involvement apart from opticospinal (OS) involvement. She also turned out to be positive for anti-myelin oligodendrocyte glycoprotein (MOG) antibody; hence, she was diagnosed with atypical multiple sclerosis. This case highlights when to…

Cannabinoids in multiple sclerosis: A neurophysiological analysis.

OBJECTIVES: To investigate the action of cannabinoids on spasticity and pain in secondary progressive multiple sclerosis, by means of neurophysiological indexes. MATERIAL AND METHODS: We assessed 15 patients with progressive MS (11 females) using clinical scales for spasticity and pain, as well as neurophysiological variables (H/M ratio, cutaneous silent period or CSP). Testing occurred before (T0) and during (T1) a standard treatment with an oral spray containing delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). Neurophysiological measures at T0 were compared with those of 14 healthy…

PSYCHIATRIC DISORDERS IN THE COURSE OF MULTIPLE SCLEROSIS.

OBJECTIVE: Multiple sclerosis (MS) is an inflammatory and demyelinating disease of the central nervous system of a chronic nature, most often with periods of exacerbation and remission, mainly affecting people between 20-40 years of age, with a slight prevalence of women. The aim of the study was to collect and analyze materials published in the literature regarding the prevalence and co-occurrence of mental disorders in patients with multiple sclerosis. Current reports show that as many as 75% of patients with this chronic disease experience various mental disorders, and the incidence of ment…

Is multiple sclerosis a risk factor for atherosclerosis?

BACKGROUND: Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. We aimed to discuss possible predisposing factors to atherosclerosis such as carotid intima-media thickness (CIMT) and high-sensitivity C-reactive protein (Hs-CRP) levels in MS. METHODS: Thirty-five ambulatory patients with relapsing-remitting MS (RRMS) (22 females and 13 males) and 34 healthy controls (21 females and 13 males) with similar demographic variables were included. Blood cell counts, cholesterol levels, vitamin D and B12, Hs-CRP levels, body mass index (BMI), history of smok…

Pharmacogenomics of Multiple Sclerosis: A Systematic Review.

Background: Over the past two decades, various novel disease-modifying drugs for multiple sclerosis (MS) have been approved. However, there is high variability in the patient response to the available medications, which is hypothesized to be partly attributed to genetics. Objectives: To conduct a systematic review of the current literature on the pharmacogenomics of MS therapy. Methods: A systematic literature search was conducted using PubMed/MEDLINE database searching for articles investigating a role of genetic variation in response to disease-modifying MS treatments, published in the Engli…

Quantification of Visual Fixation in Multiple Sclerosis.

PURPOSE: Eye movement abnormalities are common in multiple sclerosis (MS), and infrared oculography is a noninvasive method for quantification. This study aims to describe and classify abnormalities of visual fixation and their clinical relevance in MS. METHODS: A validated standardized infrared oculography protocol, Demonstrate Eye Movement Networks with Saccades, was used for quantifying gaze stability during a fixation task in MS patients and healthy controls. Saccadic intrusions, gaze drift, and stability of fixation around the drift line were used to subclassify MS patients by performing…
