Background: The plethora of troublesome signs and symptoms of multiple sclerosis (MS) reduces patients' quality of life (QOL) and coping skills. Face-to-face (F2F) education is effective and practical as it allows for more engagement and active learning. The use of mobile health technology to enhance health is now an excellent potential to establish a more efficient health system.

Objectives: It is estimated that up to 65 % of pwMS (people with multiple sclerosis) experience varying degrees of cognitive impairment, the most commonly affected domain being Information Processing Speed (IPS). As sleep disturbance is a predictor of detriments in IPS, the authors aimed to study the association between the severity of Restless Legs Syndrome (RLS) and Obstructive Sleep Apnea (OSA) symptoms with IPS in pwMS.

Methods: In a cross-sectional study, the authors enrolled people with relapsing-remitting and secondary progressive MS referred to the comprehensive MS center of Kashani Hospital in Isfahan, Iran.

Multiple sclerosis (MS) predominantly affects women of childbearing age, significantly impacting their quality of life (QOL). The diagnosis of MS can influence pregnancy intention, and the level of disability associated with MS may change before and after pregnancy. This study aims to analyze the reproductive characteristics of Iranian female patients with MS (PwMS) and their association with the Expanded Disability Status Scale (EDSS) and pregnancy tendency, providing valuable insights into disease progression and the development of tailored treatments.

Background: We aimed to explore the association between peripapillary retinal nerve fiber layer thickness (pRNFL), macular ganglion cell-inner plexiform layer (mGCIPL), and cognitive impairment (CI) in patients with neuromyelitis optica spectrum disorder (NMOSD).

Method: In this cross-sectional study, 38 (28 aquaporin-4 (AQP4) IgG-seropositive) NMOSD patients and 20 healthy controls (HC) underwent cognitive assessment using Minimal Assessment of Cognitive Function in Multiple Sclerosis (MACFIMS) battery. Spectral-domain optical coherence tomography (OCT) was performed for both eyes of all NMOSD patients.

Article Synopsis
  • - Multiple sclerosis is a serious condition, and the study compared the efficacy and safety of a biosimilar drug called Xacrel to the original drug, Ocrevus, in patients with Relapsing Multiple Sclerosis (RMS) over 96 weeks.
  • - The main goal was to see if both drugs had similar effects on reducing annual relapse rates (ARR) at 48 weeks, while also assessing other factors like disability progression, MRI results, and safety.
  • - Results showed that Xacrel was equivalent to Ocrevus in reducing ARR, with no significant differences in efficacy or safety observed during the trial, confirming Xacrel as a viable alternative to Ocrevus.

Background: COVID-19 was a viral infection that led to a global pandemic in March 2020. At the beginning of the pandemic, clinicians encountered the challenge of how immunosuppressive treatments would affect the course of COVID-19 infection in people with autoimmune diseases. Neuromyelitis optica spectrum disorder is an autoimmune astrocytopathy that is caused by an inflammation in the CNS.

Background: Multiple sclerosis (MS) is a prevalent, disabling, inflammatory, neurodegenerative disease that typically manifests during a highly productive stage of life. Interferon beta-1a was among the first approved disease-modifying therapies for MS and remains among the first-line treatment options. Pegylation of the interferon beta-1a molecule prolongs its half-life while maintaining its efficacy and safety profile.

Purpose: Several machine learning studies have used optical coherence tomography (OCT) for multiple sclerosis (MS) classification with promising outcomes. Infrared reflectance scanning laser ophthalmoscopy (IR-SLO) captures high-resolution fundus images, commonly combined with OCT for fixed B-scan positions. However, no machine learning research has utilized IR-SLO images for automated MS diagnosis.

Background: The rising prevalence of familial multiple sclerosis (MS) in Iran has spurred interest in the potential impact of parental consanguinity on the risk of developing the disease. This study aims to aggregate current knowledge on parental consanguinity and its possible effect on MS risk, particularly among familial MS patients from various regions and ethnicities in Iran. The objective is to enhance the understanding of MS genetics and encourage further research in this field.

Objective: Optical coherence tomography (OCT) investigations have revealed that the thickness of inner retinal layers becomes decreased in multiple sclerosis (MS) patients, compared to healthy control (HC) individuals. To date, a number of studies have applied machine learning to OCT thickness measurements, aiming to enable accurate and automated diagnosis of the disease. However, there have much less emphasis on other less common retinal imaging modalities, like infrared scanning laser ophthalmoscopy (IR-SLO), for classifying MS.

Article Synopsis
  • The study aimed to describe the clinical features of double-antibody seronegative neuromyelitis optica spectrum disorders (DN-NMOSD), focusing on how these disorders affect the retina.
  • Researchers analyzed data from 25 individuals with DN-NMOSD and compared it to those with aquaporin-4 antibody positive neuromyelitis optica (AQP4-NMOSD) and healthy controls, using optical coherence tomography (OCT) to assess retinal damage.
  • The findings revealed significant thinning of the retinal nerve fiber layer and ganglion cell layers in DN-NMOSD patients, even after just one optic neuritis episode, indicating severe retinal damage and neurodegeneration regardless of an ON history.

Background: Appropriate treatment reduces the severity and duration of relapses in demyelinating diseases of Central Nervous System (CNS). If high-dose corticosteroids treatment fails, therapeutic plasma exchange (TPE) is considered as a rescue treatment.

Objectives: This study aimed to investigate early clinical response and complications of TPE and prognostic factors in CNS demyelinating relapses.

Objective: The relationship between MS and ethnicity has been understudied in the Middle East compared to the United States and Europe. As Iran as the highest prevalence of MS in the Middle East, we decided to investigate the demographic and clinical differences in people with MS (pwMS) from major ethnicities Iran.

Methods: In a cross-sectional study using data from National Multiple Sclerosis Registry in Iran.

Objective: The time to diagnosis of multiple sclerosis (MS) is of great importance for early treatment, thereby reducing the disability and burden of the disease. The purpose of this study was to determine the time from the onset of clinical symptoms to the diagnosis of MS and to evaluate the factors associated with a late diagnosis in Iranian MS patients.

Methods: The present cross-sectional study was conducted on patients with MS who were registered in the National MS Registry System of Iran (NMSRI).

Working memory (WM) is one of the most affected cognitive domains in multiple sclerosis (MS), which is mainly studied by the previously established binary model for information storage (slot model). However, recent observations based on the continuous reproduction paradigms have shown that assuming dynamic allocation of WM resources (resource model) instead of the binary hypothesis will give more accurate predictions in WM assessment. Moreover, continuous reproduction paradigms allow for assessing the distribution of error in recalling information, providing new insights into the organization of the WM system.
