Psychometric properties of patient-reported outcome measures, measuring fatigue in patients with multiple sclerosis, a systematic review
Ruzzi MAJ, Coll MB, Mata MJD, Tello MCR and García IC
Multiple sclerosis (MS) is a chronic, inflammatory, degenerative disease of the central nervous system. One of the most common and disabling symptoms is fatigue. More than 80% of people with MS experience fatigue, which has a negative impact on their quality of life and level of independence in daily activities. The multidimensional nature of fatigue makes it essential to understand its impact from the patient's perspective. Patient-reported outcomes (PROs), defined by the FDA as "any report of a patient's health status that comes directly from the patient, without interpretation of the patient's response by the physician or other health care professional," were created to address this need.
Frequency of anti-MOG antibodies in serum and CSF of patients with possible autoimmune encephalitis: Results from a Brazilian multicentric study
de Freitas Dias B, Toso FF, Barreto MESF, Dellavance A, Thomaz RB, Kowacs PA, Teive H, Spitz M, Juliano AFB, Rocha LJA, Granja VNT, Braga-Neto P, Nóbrega PR, Oliveira-Filho J, Dias RM, Amoras JAP, Pereira RBR, Júnior COG, Maia FM, Santos ML, de Melo ES, Júnior AWDN, Lin K, Paolilo RB, Krueger MB, Barsottini OGP, Endmayr V, Andrade LEC, Hoftberger R and Dutra LA
MOGAD encephalitis and ADEM share several clinical features with autoimmune encephalitis (AE) associated with antineuronal antibodies (ANeA); nonetheless, treatment and prognosis differ. Anti-MOG antibodies (abs) are not routinely tested in possible AE, and epidemiological studies on MOGAD encephalitis are scarce.
Multiple Sclerosis and biological definitions in neurodegenerative diseases
Camara-Lemarroy CR
Recently, biological definitions in Alzheimer´s disease (AD) and Parkinson´s disease (PD) have been proposed, where clinical descriptors such as "dementia" or "parkinsonism" lost the spotlight. Similar changes are in the horizon in Multiple Sclerosis (MS). However, in MS there is no single molecule (like amyloid) to call the main driver of MS pathogenesis. In fact, there has not been a historically steady candidate. Decades ago T-cells were thought to be paramount, then brain atrophy, and recently the heterogeneous concept of "smoldering disease". There are no established minimal necessary and sufficient conditions for disease pathogenesis in MS. Ethical issues will be important. Technology for biological/biomarker assessments is not universally available and there is risk of overmedicalization. Groups such as the Movement Disorders Society have expressed reservations about pure biological definitions for PD. In MS, we are just in time to tackle these issues in a critical and constructive way.

Arun T, Petheram K, Tallantyre E, Ford H, Chataway J, Dougall NM, Doshi A, Englezou C, Farrell R, Hughes S, Donnell GM, Murray K, Rees R, Robertson N, Schmierer K, Dobson R and
Therapeutics of neuroinflammatory disorders including multiple sclerosis is one of the fastest growing areas in neurology. However, pressures on higher specialty training in neurology together with an expanding curriculum have led to challenges in adequately preparing trainees for a subspecialist career. In this study we set out to understand current perceptions and barriers to training in neuroinflammatory disorders among neurology trainees in the UK. A structured questionnaire was used to assess trainees' perspectives on training opportunities and career aspirations. Findings reveal significant gaps in training, including insufficient training opportunities, lack of mentorship, and concerns about managing complex treatment regimes. We used these findings to develop structured action points with aim of improving training and retention in this subspecialty. These include early exposure to subspecialty experiences, enhanced mentorship, and equal access to training opportunities regardless of geographical location. Our findings underscore the need for further curriculum development in neurology training, potentially combining early support with dedicated fellowships later in training, in order to ensure sustainability of neuroinflammation as a subspecialty and to meet the growing demand for expertise in MS and related conditions.

However, knowledge regarding neuropathic pain-related medications is lacking OBJECTIVE: Compare odds of anticonvulsant/gabapentinoid prescriptions for 4,862 MS-cases versus 22,669 controls, pre-MS onset (defined as first demyelinating disease-related event).
Strength training attenuates neuropathic pain by Preventing dendritic Spine dysgenesis through Suppressing Rac1 and inflammation in experimental autoimmune encephalomyelitis
Saffar Kohneh Quchan AH, Kordi MR, Mohammadi G, Amiri Raeez R and Choobineh S
Chronic pain is a challenge and major health problem to basic science and clinical practice. Pain is one of the worst symptoms of multiple sclerosis (MS), which has a significant impact on their quality of life. Rac1 is an important intracellular signaling molecule involved in spinal dendritic spine pathology and activation of IL-1β and TNF-α that are associated with chronic neuropathic pain. As a result, targeting Rac1 presents a promising approach to managing neuropathic pain. Clinical studies have demonstrated that physical exercise is a non-pharmacological strategy that positively influences disease progression in individuals with MS, but underlying mechanism of exercise on Rac1- induced neuropathic pain is not well understood. This study examined the effects of a 4-week strength training on Rac1 expression, IL-1B, TNF-α, TGF-β1 levels, MDA concentrations, SOD activity, dendritic spine abnormalities in the dorsal horn of the spinal cord, as well as nociceptive behaviors (formalin test) and motor function (Rotarod test) during the chronic phase of experimental autoimmune encephalomyelitis (EAE). The findings indicated that strength training increased TGF-β1 expression and SOD activity while decreasing the expression of Rac1, IL-1β, TNF-α, and MDA and reducing dendritic spine dysgenesis in the dorsal horn of the spinal cord. We observed strength training effectively reduced nociceptive behaviors and improved motor function in mice with EAE. In summary, regular physical exercise may modulate neuropathic pain through inhibition of dendritic spine dysgenesis, inflammation and oxidative stress in the dorsal horn of the spinal cord.

The real-world impact of biologics for NMOSD: A retrospective single-center study compared with natural course and conventional treatments in Japanese
Yamazaki N, Misu T, Matsumoto Y, Takai Y, Namatame C, Ono H, Kaneko K, Nishiyama S, Kuroda H, Takahashi T, Nakashima I, Fujihara K and Aoki M
Neuromyelitis optica spectrum disorder (NMOSD), a central nervous system inflammatory disease associated with aquaporin-4 immunoglobulin G (AQP4-IgG), is conventionally treated with oral steroids and immunosuppressants (IS) in Japan. Several biologics which show great efficacy in the clinical trials have been developed recently. However, studies on their efficacy, especially those comparing them with conventional treatments in real-world situations are lacking.

Epstein-Barr nuclear antigen 1 antibody-based indices are increased in patients with multiple sclerosis
Ali R, Trier NH, Houen G and Frederiksen JL
Multiple sclerosis (MS) is a chronic central nervous system (CNS) disease, which is diagnosed by a combination of clinical symptoms and magnetic resonance imaging and measurement of an increased intrathecal antibody synthesis. Genetic as well as environmental factors influence onset of the disease, where especially Epstein-Barr virus (EBV) infection is directly involved in MS development. In this open retrospective study, we aimed to elaborate whether various serum and cerebrospinal fluid (CSF)-based EBV antibody indices may aid in the diagnosis of MS.
Time between the first symptom, diagnosis and treatment of multiple sclerosis in a Brazilian cohort. The impact of early diagnosis
de Melo JRV, Marzano LAS, Kleinpaul R and Santiago-Amaral J
Multiple Sclerosis (MS) diagnosis can be challenging, especially in populations where the disease is rare. In Brazil, the average prevalence is 14/100,000 inhabitants, lower than the worldwide. Early treatment initiation can markedly reduce disease activity and accumulation of disability. Therefore, delayed diagnosis and access to disease modifying therapy (DMT) can have a negative impact on the course of MS.
