Modafinil in treatment of fatigue in multiple sclerosis. Results of an open-label study.

BACKGROUND: Modafinil is a unique wake-promoting agent that is chemically distinct from traditional stimulants. Results of a placebo-controlled study showed it to improve fatigue in multiple sclerosis (MS) at a dose of 200 mg daily, but not at a dose of 400 mg daily. OBJECTIVE: To establish the efficacy, safety and appropriate dose of modafinil in the treatment of fatigue and sleepiness in patients with multiple sclerosis. METHOD: A total of 50 patients diagnosed with MS (mean age 40.4 +/- 10.3 years, 30 females/20 males; MS type: 36 relapsing remitting, 1 primary progressive, 13 secondary p…

Aging and Neurodegenerative Disease: Is the Adaptive Immune System a Friend or Foe?

Neurodegenerative diseases of the central nervous system (CNS) are characterized by progressive neuronal death and neurological dysfunction, leading to increased disability and a loss of cognitive or motor functions. Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis have neurodegeneration as a primary feature. However, in other CNS diseases such as multiple sclerosis, stroke, traumatic brain injury, and spinal cord injury, neurodegeneration follows another insult, such as demyelination or ischaemia. Although there are different primary causes to these diseases, they al…

Mitochondrial Disorders May Mimic Amyotrophic Lateral Sclerosis at Onset.

Similarities between a mitochondrial disorder (MID) and amyotrophic lateral sclerosis (ALS) fade with disease progression and the development of mitochondrial multiple organ dysfunction syndrome (MIMODS). However, with mild MIMODS, a MID may still be misinterpreted as ALS. We report a 48-year-old male who presented to the Neurological Hospital Rosenhügel, Vienna, Austria, in February 2001 with slowly progressive weakness, wasting and left upper limb fasciculations which spread to the shoulder girdle and lower limbs. Additionally, he developed tetraspasticity and bulbar involvement. He had been

Double-Blind Controlled Randomized Trial of Cyclophosphamide versus Methylprednisolone in Secondary Progressive Multiple Sclerosis.

BACKGROUND: Therapeutic options are limited in secondary progressive multiple sclerosis (SPMS). Open-label studies suggested efficacy of monthly IV cyclophosphamide (CPM) without induction for delaying progression but no randomized trial was conducted so far. OBJECTIVE: To compare CPM to methylprednisolone (MP) in SPMS. METHODS: Randomized, double-blind clinical trial on two parallel groups. Patient with SPMS, with a documented worsening of the Expanded Disability Status Scale (EDSS) score during the last year and an EDSS score between 4·0 and 6·5 were recruited and received one intravenous …

Autologous mesenchymal stem cell therapy in progressive multiple sclerosis: an open label study.

Despite updating knowledge and a growing number of medications for multiple sclerosis (MS), no definite treatment is available yet for patients suffering from progressive forms of the disease. Autologous bone marrow derived mesenchymal stem cell (BM-MSC) transplantation is a promising method proposed as a therapy for MS. Although the safety of these cells has been confirmed in hematological, cardiac and inflammatory diseases, its efficacy in MS treatment is still under study. Patients with progressive MS (expanded disability status scale score: 4.0 -6.50) unresponsive to conventional treatment…

Vitamin D status, supplementation, and multiple sclerosis: a systematic review and meta-analysis.

BACKGROUND: Multiple sclerosis (MS) is a chronic immune-mediated neurodegenerative disorder of the central nervous system and a leading cause of disability among young adults. The disease exhibits considerable heterogeneity in clinical progression, with some patients experiencing more aggressive disease activity and a rapid decline in quality of life. Vitamin D plays a key role in immune regulation, and evidence suggests that its deficiency constitutes a significant environmental risk factor for immune-mediated conditions such as MS. While there are controversies regarding the role of serum 25…

Pediatric demyelinating diseases.

PURPOSE OF REVIEW: In the past decade, the number of studies related to demyelinating diseases in children has exponentially increased. Demyelinating disease in children may be monophasic or chronic. Typical monophasic disorders in children are acute disseminated encephalomyelitis and clinically isolated syndromes, including optic neuritis and transverse myelitis. However, some cases of acute disseminated encephalomyelitis or clinically isolated syndrome progress to become chronic disorders, including multiple sclerosis and neuromyelitis optica. This review summarizes the current knowledge on …

Flupirtine as neuroprotective add-on therapy in autoimmune optic neuritis.

Multiple sclerosis (MS) is a common inflammatory disease of the central nervous system that results in persistent impairment in young adults. During chronic progressive disease stages, there is a strong correlation between neurodegeneration and disability. Current therapies fail to prevent progression of neurological impairment during these disease stages. Flupirtine, a drug approved for oral use in patients suffering from chronic pain, was used in a rat model of autoimmune optic neuritis and significantly increased the survival of retinal ganglion cells, the neurons that form the axons of the…

Recent advances in neurodegenerative diseases therapeutics: The inhibition of monoacylglycerol lipase strategy.

Neurodegenerative diseases share common pathophysiological mechanisms, including chronic neuroinflammation, glutamatergic excitotoxicity, ox … neuronal excitotoxicity. Preclinical studies in models of Alzheimer's disease, Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis consistently demonstrate that MAGL blockade attenuates neuroinflammation, preserves synaptic and neuronal integrity, improves motor and cognitive function, and, in some cases, delays disease progression. Although c …

патогенный синергизм: дисфункциональная митохондрия и нейронное воспаление в нейродегенеративных заболеваниях, связанных со старением.

Термин " нейродегенеративные заболевания " (НДД) относится к целому ряду заболеваний, связанных со старением, включая болезнь Альцгеймера, болезнь Паркинсона и амиотропический боковой склероз. Уникальные клинические симптомы и основные патологические механизмы отличают каждое из этих заболеваний. Хотя эти условия отличаются друг от друга, они имеют хроническую нейроинфламму в качестве определяющей характеристики. Считается, что агрегация протеина и митохондриальная дисфункция играют определенную роль в инициировании нейроинфламмативной реакции, а затем в развитии и развитии этих забо

[A NEW MULTIPLE SCLEROSIS DIAGNOSIS IN A PATIENT WITH INTERMEDIATE UVEITIS].

Uveitis is a group of about 30 intra-ocular inflammatory diseases; multiple sclerosis (MS) is an immune-mediated chronic inflammatory disease of the central nervous system (CNS). Intermediate uveitis has been reported to be the most common type of uveitis in association with MS. The mechanism associating MS and uveitis is not clear, but previous data suggest a genetic predisposition may play a role. In addition, MS patients presenting with uveitis prior to the onset of neurological symptoms tend to demonstrate a milder form of the disease with moderate progression. This observation may be attr…

Tertiary lymphoid structures in the central nervous system.

Tertiary lymphoid structures (TLSs) frequently occur at sites of chronic inflammation. A more advanced stage of multiple sclerosis (MS) has been associated with certain TLSs. However, tumor-associated TLSs have been shown to correlate with a greater treatment response rate and a better prognosis in glioma mouse models. In this review, we evaluate the clinical significances of TLSs in prognosis and treatment response, as well as the status of TLS-directed therapies targeting alternative biochemical pathways in various central nervous system (CNS) disorders. Potential molecular mechanisms underl…

Vascular risk factors are associated with grey matter atrophy in secondary progressive multiple sclerosis.

BACKGROUND: Comorbidities including vascular risk factors can be associated with whole and regional brain atrophy in multiple sclerosis (MS). This has been examined in mixed MS cohorts in prospective or observational studies; however, the association between vascular comorbidities (VCM) in secondary progressive MS (SPMS) and brain atrophy has been less well studied. The aim was to investigate the cross-sectional and longitudinal association between VCM, comorbidity burden and brain atrophy in SPMS. METHODS: Post hoc analysis of 445 participants from the MS-Secondary Progressive multi-arm tria…

Hand functioning in progressive multiple sclerosis improves with tDCS added to daily exercises: A home-based randomized, double-blinded, sham-controlled clinical trial.

BACKGROUND: Many individuals with progressive multiple sclerosis (PMS) are challenged by reduced manual dexterity and limited rehabilitation options. Transcranial direct current stimulation (tDCS) during motor training can improve rehabilitation outcomes. We developed a protocol for remotely supervising tDCS to deliver sessions of stimulation paired with training at home. OBJECTIVE: This study evaluated the effectiveness of at-home tDCS paired with manual dexterity training for individuals with PMS. METHODS: Sixty-five right-hand dominant participants with PMS and hand impairment were random…

Axonal loss in non-optic neuritis eyes of patients with multiple sclerosis linked to delayed visual evoked potential.

OBJECTIVE: Recent studies demonstrate significant thinning of the retinal nerve fiber layer (RNFL) in multiple sclerosis (MS) non-optic neuritis (MS-NON) eyes. However, the pathologic basis of this reduction is not clear. The aim of the current study was to investigate the relationship of the RNFL thickness in MS-NON eyes with latency delay of the multifocal visual evoked potential (mfVEP), a surrogate marker of the visual pathway demyelination. METHODS: Total and temporal RNFL thickness and latency of the mfVEP in 45 MS-NON eyes of 45 patients with relapsing-remitting MS and 25 eyes of age- …

Immune reconstitution and tolerance-inducing therapies as promising therapeutic approaches in multiple sclerosis.

OBJECTIVES: Multiple sclerosis (MS) is a complex, progressive neurodegenerative autoimmune disease and a major cause of neurological disability worldwide. MS affects approximately 2.8-3 million people, predominantly presenting as relapsing-remitting MS (RRMS) that frequently converts to secondary progressive disease, while effective options for progressive phenotypes remain limited. METHODS: This review reframes MS immunotherapy through a tolerance-centric paradigm, distinguishing continuous maintenance disease-modifying therapies (DMTs) from immune reconstitution therapies (IRTs) and emergin…
