Background: Adherence to prescribed treatment in chronic diseases, as occurs in multiple sclerosis (MS), is a critical factor for a successful therapeutic response. This study aimed to investigate the effect of educational program based on Theory of Planned Behavior (TPB) on treatment adherence in patients with multiple sclerosis (MS) receiving injectable immunomodulatory drugs.
Methods: The present study is an educational randomized controlled trial research that was conducted on 100 patients with MS who had gone to MS clinic in Tehran city (Iran). The samples were randomly assigned to the intervention (N = 50) and control groups (N = 50). Data collection instrument was a researcher-made questionnaire based on TPB. Then, educational program was performed for the intervention group through four educational sessions. After three months, data collection was repeated for the two groups and data were analyzed.
Results: The knowledge and performance of the intervention group on treatment adherence drugs increased from 56.25 ± 20.3 to 78.31 ± 15.57 and 56.22 ± 5.76 to 71.62 ± 12.01 after the education respectively (p < 0.001). The mean of construct of TPB in the intervention group also increased after the intervention (p < 0.05).
Conclusion: Applying the TPB model proved is very effective in developing an educational program for patients with MS, to enhance treatment adherence drugs. Besides such programs, follow-up education for controlling and monitoring are highly recommended.
Trial Registration: This trial has been registered at Iranian Registry of Clinical Trials, IRCT20210808052109N1. Prospectively registered at 12-Aug-2021, (12/8/2021) available at: URL: https://en.irct.ir/trial/57994.

In recent decades, researchers and clinicians have increasingly focused on glial cell function. One of the primary mechanisms influencing these functions is through extracellular vesicles (EVs), membrane-bound particles released by cells that are essential for intercellular communication. EVs can be broadly categorized into four main types based on their size, origin, and biogenesis: large EVs, small EVs (sEVs), autophagic EVs, and apoptotic bodies.

The Canadian Association of Radiologists (CAR) Central Nervous System Expert Panel is made up of physicians from the disciplines of radiology, emergency medicine, neurosurgery, and neurology, a patient advisor, and an epidemiologist/guideline methodologist. After developing a list of 24 clinical/diagnostic scenarios, a rapid scoping review was undertaken to identify systematically produced referral guidelines that provide recommendations for one or more of these clinical/diagnostic scenarios. Recommendations from 55 guidelines and contextualization criteria in the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) for guidelines framework were used to develop 51 recommendation statements across the 24 scenarios.

Introduction: As the most frequent chronic neurological disorder in young adults, Multiple sclerosis (MS) significantly affects neurological function, particularly the autonomic nervous system. While the physical symptoms are visible, MS also causes hidden effects like sexual dysfunction. Research indicates that sexual disorders are more prevalent in MS patients compared to other neurological conditions and are approximately five times more common than in the general population.

DOPA Decarboxylase (DDC) has been proposed as a cerebrospinal fluid (CSF) biomarker with increased concentrations in Lewy body disorders (LBDs) and highest levels in patients receiving dopaminergic treatment. Here we evaluate plasma DDC, measured by proximity extension assay, and the effect of dopaminergic treatment in three independent LBD (with a focus on dementia with Lewy bodies (DLB) and Parkinson's disease (PD)) cohorts: an autopsy-confirmed cohort (n = 71), a large multicenter, cross-dementia cohort (n = 1498) and a longitudinal cohort with detailed treatment information (n = 66, median follow-up time[IQR] = 4[4, 4] years). Plasma DDC was not altered between different LBDs and other disease groups or controls in absence of treatment.

Ocrelizumab (OCR) and Natalizumab (NTZ) are highly effective treatments widely used in Multiple Sclerosis (MS). However, long-term, real-world comparative data on clinical effectiveness, safety and treatment persistence are limited. This retrospective analysis included relapsing and progressive MS patients initiating treatment at two Italian Universities ("La Sapienza" and "Federico II").
