Intellectual disability (ID) is a leading cause for referral to genetic services, with the most severe cases typically attributed to single genetic defects. This study aimed to evaluate the diagnostic yield of cost-effective proband-only exome sequencing for individuals diagnosed with ID within the Iranian population for the first time where a high rate of parental consanguinity exists. A total of 99 unrelated patients with ID were investigated by exome sequencing during 8 years.

A large percentage of patients with Parkinson's disease (PD) suffer from excessive daytime sleepiness (EDS). This study aims to compare the effectiveness of modafinil and methylphenidate on EDS and side effects. Fifty nine patients with PD and EDS [Epworth Sleepiness Scale (ESS) more than 9] were recruited in a double-blind placebo controlled trial.

Article Synopsis
  • - Neurodegeneration with Brain Iron Accumulation (NBIA) is a rare hereditary disease, and this study aimed to assess how long patients can maintain mobility and survive, analyzing data from 122 patients over 11 years.
  • - The findings highlighted significant survival and ambulation probabilities among different subtypes of NBIA, with Kufor Rakeb Syndrome (KRS) showing the best outcomes, while classical PKAN and MPAN presented similar challenges in mobility loss over time.
  • - Spasticity was identified as the most critical factor associated with increased mortality, indicating that managing this symptom could potentially improve patient outcomes in NBIA.

Background And Purpose: There is growing evidence that dietary modification can improve clinical manifestations in multiple sclerosis (MS) patients. This study aimed to assess the impact of synbiotics and anti-inflammatory-antioxidant-rich diet on fatigue, pain, gut and bladder status, and sexual function in patients with progressive forms of MS.

Materials And Methods: In this single-center, single-blind, randomized, controlled clinical trial, seventy participants with three forms of progressive MS (primary-progressive, secondary-progressive, and progressive-relapsing) were randomly assigned to receive either synbiotics supplement and anti-inflammatory-antioxidant-rich diet or a placebo along with their usual diet for a duration of four months.

Purpose Of Review: The current article aims to provide an overview of new daily persistent headache (NDPH), with a particular emphasis on its pathophysiology, evaluation, and current treatment options.

Recent Findings: NDPH is an uncommon and heterogeneous condition associated with various comorbidities and is of great significance due to its prolonged duration and high severity. Variable causes and clinical aspects of NDPH may reflect differences in its underlying pathophysiological mechanisms, including genetics, environmental triggers, neuroinflammation, and brain changes.

Background: People with multiple sclerosis (pwMS) on anti-CD20 therapies (aCD20) and fingolimod have shown inadequate humoral responses to COVID-19 vaccines.

Objective: The objective of the study was to pilot larger studies by demonstrating the safety and comparing the immunogenicity of different types of third doses in seronegative pwMS after two doses of BBIBP-CorV inactivated vaccine.

Methods: In December 2021, subject to receiving their third dose, being COVID-19-naiive, and receiving no corticosteroid within two months, we measured the level of anti-SARS-CoV-2-Spike IgG in pwMS seronegative after two shots of BBIBP-CorV inactivated vaccine.

Background: The minimum data set (MDS) is one of the important steps in the development of health care information systems. According to the Ministry of Health in Iran, a central and national registry along with Parkinson's MDS (PMDS) has not yet existed. So, this research was conducted to establish a PMDS in Iran.

Background: Current evidence has demonstrated that patients with Multiple Sclerosis (MS) have dysbiotic gut microbiomes, and anti-inflammatory nutritional interventions can normalize this status. Therefore, we aimed to investigate the effects of dietary intervention in patients with progressive forms of MS.

Methods: Seventy patients with three forms of progressive MS (primary-progressive, secondary-progressive, and progressive-relapsing) were randomly assigned into intervention (daily synbiotics capsule plus anti-inflammatory-antioxidant rich diet) or control (placebo capsule plus dietary recommendations) groups for four months.

The impairment of limb function and disability are among the most im portant consequences of stroke. To date, however, little research has been done on the early reha bilitation trial (ERT) after stroke in these patients. The purpose of this study was to evaluate the impact of ERT neuromuscular protocol on motor function soon after hemiparetic stroke.

Introduction: Migraine is recognized as a complex neurological disorder that has imposed a social burden. We assessed the signaling pathways and molecular mechanisms based on the in silico analysis and predicted drug candidates by the biomedicine approach. Moreover, we evaluated high-intensity interval training and vitamin B12 + magnesium on women's migraine attacks and inflammatory status.

Background: Various studies indicated blunted humoral responses to COVID-19 mRNA and viral vector vaccines among people with multiple sclerosis (pwMS) on sphingosine 1-phosphate receptor (S1PR) modulators and anti-CD20 therapies (aCD20); however, limited evidence was found regarding SARS-CoV-2 serology after inactivated virus vaccination.

Objective: To provide evidence regarding humoral response to COVID-19 inactivated virus vaccination among pwMS on disease-modifying therapies (DMTs).

Methods: A cohort study was carried out in Isfahan, Iran, enrolling DMT-exposed pwMS and unexposed (UX) healthy participants.

Background: Various articles show the high prevalence of sleep disorders and especially excessive daytime sleepiness (EDS) in patients with refractory epilepsy and the importance of personal and social burden of this complication on individuals. Considering the insufficient evidence to draw efficacy and safety of modafinil and methylphenidate to treat EDS in the patient with intractable seizures, we decided to compare the effect of methylphenidate and modafinil with the control group. It is hoped that this study will pave the way for further studies.

The aim of this study was to evaluate the status of anti-myelin oligodendrocyte glycoprotein (MOG) antibodies in patients with transverse myelitis (TM) and compare the clinical and imaging characteristics of MOG immunoglobulin G (IgG)-positive with negative cases. This cohort study enrolled 71 patients diagnosed with new-onset of TM who were being followed at a referral university clinic in Isfahan, Iran, from November 2016 to January 2019. Magnetic resonance imaging (MRI) images and blood samples for anti-MOG, anti-aquaporin 4 (anti-AQP4) (using the cell-based technique), and vasculitis-related antibodies were collected from patients.

Background: Fampridine was first approved by the US Food and Drug Administration (FDA) to improve walking in multiple sclerosis (MS) patients, which was demonstrated by an increase in their walking speed. Nevertheless, the medication has been reported to possess an epileptogenic effect since it blocks the voltage-gated potassium channels in neural fibers. Several studies have indicated that the risk of seizure among fampridine consumers is not substantially higher than that in the general MS population, however.

Parkinson's disease (PD) as one of the most common neurodegenerative disorders may be affected by healthy dietary pattern. The aim of this study was to investigate the effects of the Mediterranean Diet (MeD) on serum Total Antioxidant Capacity (TAC) and disease severity in PD patients. In this single-center randomized clinical trial, patients with idiopathic PD ( = 80) were selected randomly allocated to either MeD or control group (Iranian traditional diet); an individualized dietary plan based on the MeD was designed.
