Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. Its etiology is not known, but it is well established that auto-reactive T-cells and monocytes play an important pathogenetic role. The inflammation causes focal demyelination and loss of axons, neurons and glial cells. Typical symptoms and signs are monocular blurred vision, double vision, sensory symptoms and motor weakness, and eventually also cognitive deficits and a disturbed micturition. In younger patients the neurological deficits tend to be present for a limited time and then to improve and disappear, only to be followed by new and different deficits later on. Each relapse may leave neurological deficits which in a later course tend to progress slowly, uninterrupted by remissions. When older patients present for the first time with MS, they tend to present with primary progressive spasticity. Important ancillary tests and findings to confirm the diagnosis are multiple focal lesions on MR images, oligoclonal bands in the cerebrospinal fluid, and slowed evoked potentials. Relapses are treated with corticosteroids. Immunomodulation with beta-interferons or glatiramer acetate reduce the number and severity of relapses and long-term disability. Very active forms can be treated with immunosuppression using mitoxantrone. Individual manifestations such as urinary tract infections or paroxysmal phenomena should be treated accordingly with medication.

Botulinum toxin blocks acetylcholine release at the neuromuscular junction. The drug which was initially found to be useful in the treatment of strabismus has been extremely effective in the treatment of variety of conditions, both cosmetic and noncosmetic. Some of the noncosmetic uses of botulinum toxin applications include treatment of spastic facial dystonias, temporary treatment of idiopathic or thyroid dysfunction-induced upper eyelid retraction, suppression of undesired hyperlacrimation, induction of temporary ptosis by chemodenervation in facial paralysis, and correction of lower eyelid spastic entropion. Additional periocular uses include control of synchronic eyelid and extraocular muscle movements after aberrant regeneration of cranial nerve palsies. Cosmetic effects of botulinum toxin were discovered accidentally during treatments of facial dystonias. Some of the emerging nonperiocular application for the drug includes treatment of hyperhidrosis, migraine, tension-type headaches, and paralytic spasticity. Some of the undesired side effects of periocular applications of botulinum toxin inlcude ecchymosis, rash, hematoma, headache, flu-like symptoms, nausea, dizziness, loss of facial expression, lower eyelid laxity, dermatochalasis, ectropion, epiphora, eyebrow and eyelid ptosis, lagophthalmos, keratitis sicca, and diplopia.

Paraneoplastic movement disorders are part of the spectrum of paraneoplastic syndromes caused by the production of onconeural antibodies such as anti-Hu by underlying tumours. These attack specific neurons depending on receptor aetiology. We report the case of a 53-year-old man who presented 8 years previously with symptoms of upper limb weakness, light headedness, dizziness and falls. His condition followed a progressive course. Two years after onset he had right-sided weakness, diplopia and generalised dystonia. Initial investigations identified a positive anti-Hu antibody, but an extensive search for a primary tumour was negative. A malignant fibrous histiocytoma in his right gluteal fold was subsequently identified. At this stage he was bed bound with severe ataxia, dystonia and spasticity. Following surgical excision and treatment with high dose steroids and pulse immunoglobulin, further progression was arrested and minor improvements occurred. He can now ambulate with bilateral assistance but remains severely disabled.

Multiple sclerosis (MS) is a chronic progressive demyelinating disease of the central nervous system. Common manifestations include paresthesias, diplopia, loss of vision, numbness or weakness of the limbs, bowel or bladder dysfunction, spasticity, ataxia, fatigue, and mental changes. Four main patterns of MS are recognized: relapsing remitting, primary progressive, secondary progressive, and progressive relapsing. The cause of MS is unknown, although it appears to be an autoimmune disease. Much of what is known about MS has been learned from an animal model of the disease, experimental allergic encephalomyelitis.

Juvenile amyotrophic lateral sclerosis (jALS) is characterized by progressive upper and lower motor neuron degeneration leading to facial muscle spasticity, spastic dysarthria, and spastic gait with an early onset (before 25 years old). Unlike adult-onset amyotrophic lateral sclerosis (ALS), patients with jALS tend to have slower progression of motor neuron disease and prolonged survival to a normal life expectancy. Mutations in FUS gene have been reported in jALS,(1) including p.P525L mutation that has been consistently associated with early onset and aggressive presentation.(2) Here, we report a patient carrying p.P525L FUS mutation and experiencing an aggressive course of ALS presenting with dysphonia and diplopia.

Purpose of review The purpose of this review is to provide updated information on the role of botulinum neurotoxin (BoNT) therapy in multiple sclerosis (MS). This review aims to answer which symptoms of multiple sclerosis may be amenable to BoNT therapy. Recent findings We searched the literature on the efficacy of BoNTs for treatment of MS symptoms up to April 1st 2017 via the Yale University Library's search engine including but not limited to Pub Med and Ovis SP. The level of efficacy was defined according to the assessment's criteria set forth by the Subcommittee on Guideline Development of the American Academy of Neurology. Significant efficacy was found for two indications based on the available blinded studies (class I and II) and has been suggested for several others through open-label clinical trials. Summary There is level A evidence (effective- two or more class I) that injection of BoNT-A into the bladder's detrusor muscle improves MS-related neurogenic detrusor overactivity (NDO) and MS-related overactive (OA) bladder. There is level B evidence (probably effective- two class II studies) for utility of intramuscular BoNT-A injections for spasticity of multiple sclerosis. Emerging data based on retrospective class IV studies demonstrates that intramuscular injection of BoNTs may help other symptoms of MS such as focal tonic spasms, focal myokymia, spastic dysphagia, and double vision in internuclear ophthalmoplegia. There is no data on MS-related trigeminal neuralgia and sialorrhea, two conditions which have been shown to respond to BoNT therapy in non-MS population.

Multiple sclerosis (MS) is a demyelinating neurodegenerative disease with lesions involving the central nervous system. Clinical symptoms consist of disturbances in motor activity (e.g., weakness, spasticity, and tremor), sensory functioning (e.g., pain), visual functions (e.g., diplopia and optic neuritis), besides different cognitive (attention deficit and executive dysfunction) and behavioral abnormalities. This review aims to evaluate the role of VR tools in cognitive and motor rehabilitation of MS patients. Studies performed between 2010 and 2017 and fulfilling the selected criteria were searched on PubMed, Scopus, Cochrane and Web of Sciences databases, by combining the terms "VR rehabilitation" and "MS". Our findings showed that, following the use of VR training, MS patients presented a significant improvement in motor (especially gait and balance) and cognitive function (with regard to executive and visual-spatial abilities, attention and memory skills). This review supports the idea that rehabilitation through new VR tools could positively affect MS patients' outcomes, by boosting motivation and participation with a better response to treatment.
