    Background

    Considering the high probability of suicidal behaviors in multiple sclerosis (MS) population of other countries and the unlikeliness of its diagnosis in patients with MS by specialists, the current research targets the frequency of suicidal thoughts and mood symptoms in a group of patients with MS in Iran. Also, we investigated the relationships among suicidal thoughts, anxiety, depression, anticipated stigma, social support, some disease characteristics, and sociodemographic factors.

    Methods

    A sample of 276 subjects were selected from community-based MS clinics and referral out-patient MS clinic of Sina Hospital affiliated to Tehran University of Medical Sciences, Tehran, Iran. Participants completed the Patient Health Questionnaire (PHQ), the Hospital Anxiety and Depression Scale (HADS), the Chronic Illness Anticipated Stigma Scale (CIASS), the Multidimensional Scale of Perceived Social Support (MSPSS), and a personal information questionnaire.

    Results

    36.2% of the participants had suicidal thoughts. Suicidal ideation was significantly more likely among people who reported higher anxiety and depression scores or anticipated stigma from their friends and families. Women and patients with higher education experienced suicidal ideation more frequently than others.

    Conclusion

    The importance of comorbidities of suicidal thoughts with anticipated stigma, depression, and anxiety in patients with MS, emphasizing the need for paying attention to it, and considering effective therapeutic interventions focused on alleviating perceived stigma as well as mood symptoms.

    Background
    Myasthenia gravis (MG) is a chronic neuromuscular disease, which physically and mentally affects the patient’s life, with depression being one of the most important psychological complications in these patients. This study aims to investigate the prevalence of depression and its associated factors in a group of Iranian patients with MG.
    Methods
    This was a cross-sectional study in which consecutive patients diagnosed with MG who referred to two referral neuromuscular clinics affiliated to the Tehran University of Medical Sciences, Tehran, Iran, were evaluated for eligibility. Patients with a previously known psychiatric disorder and those with a family history of mental disorders were excluded. Eligible patients were interviewed and screened for depression through the administration of the Hamilton Depression Rating Scale (HDRS) and the Iranian version of Beck Depression Inventory-II (BDI-II).
    Results
    A total of 62 patients participated in this study. The total prevalence of depression according to the HDRS and BDI-II scores was 64.5% and 53.2%, respectively. The mild depression was the most frequent level of depression based on the HDRS (33.9%) and BDI-II (22.6%) scores. None of the variables, including age, sex, duration of the disease, and dosages of prednisolone, pyridostigmine, and azathioprine, were correlated with the severity of depression. The number of academic years was the only variable associated with the lower HDRS score (P = 0.037).
    Conclusion
    Based on the current findings, depression was common among Iranian patients with MG. The severity of depressive symptoms was unrelated to age, sex, marital status, duration of the disease, the daily dosage of medications, and thymectomy status. Further investigations are needed to reveal the exact burden of depression in patients with MG and address the importance of preventive interventions for improving the quality of life (QOL) in these patients.

    Background
    The cognitive impairment in patients with generalized epilepsy may affect their social efficiency and quality of life (QOL). The aim of this study is to determine the cognitive dysfunction and related risk factors in patients with generalized epilepsy as compared to patients with non-epileptic neurological disorders.
    Methods
    In the present descriptive cross-sectional study, the cognitive function was assessed by Montreal Cognitive Assessment (MoCA) test in 62 patients with generalized epilepsy and also 62 patients with non-epileptic neurological diseases who referred to the Neurology Clinic, Semnan University of Medical Sciences, Semnan, Iran. The relationship between cognitive impairment and related risk factors was also investigated. The data were analyzed by SPSS software.
    Results
    The mean score of MoCA in the patients with generalized epilepsy and the control group was 22.80 ± 4.14 and 26.48 ± 2.85, respectively (P < 0.050). The results indicated significantly lower MoCA scores in the epileptic group rather than the non-epileptic one (P < 0.001). Moreover, there was a significant relationship between MoCA score and age, education level, living place, the dose and rate of medicines, and the number of seizures in patients with epilepsy (P < 0.001). Gender and the duration of disease had no significant effects on the cognitive impairment of patients with epilepsy (P > 0.05).
    Conclusion
    Patients with epilepsy had a significant cognitive impairment as compared to the patients with non-epileptic neurological disorders. Age, education level, living place, the dose and rate of medicines, and the number of seizures were the risk factors of cognitive impairment in the patients with epilepsy, while duration of disease and gender had no effects on the intensity of cognitive deficits.

    Background

    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.

    Methods

    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. Outcomes were assessed by the evolution of the Expanded Disability Status Scale (EDSS) score and brain and spinal cord imaging findings  within three months. All patients underwent imaging and clinical assessment during a mean period of one year as a follow-up. We compared the characteristics of clinical and radiological outcomes in MOG-IgG-positive and negative cases.

    Results

    Of the total population studied, there were 26.8% men and 73.2% women, with a mean age of 33 ± 10 years. 12 (16.9%) patients were seropositive for MOG antibody and 17 (89.5%) were positive for anti-AQP4 antibodies. There was no significant association between anti-MOG antibody seropositivity and age, gender distribution, the presence of other autoimmune diseases, and number and interval of relapses. However, the involvement site of the spine at first imaging was significantly different between seronegative and seropositive patients.

    Conclusion

    In patients with MOG antibody disease (MOG-AD) TM, the MRI findings suggest a preferential involvement of the cervical-thoracic section in seropositive cases which may help differentiate from non-MOG demyelination TM.

    Background

    Multiple sclerosis (MS) is an inflammatory disease of the central nervous system (CNS) with the most common complaint of fatigue. A high number of patients with MS are interested in taking dietary supplements as a complementary therapy. We propose a specially formulated supplement for patients with MS and aim to evaluate its effects on fatigue.

    Methods

    This study was a triple-blind, randomized, placebo-controlled trial using a stratified randomization method according to sex. 46 eligible patients participated in the study, 23 in the placebo group and 23 in the intervention group. The intervention group received two capsules of multivitamin-mineral (MVM) daily for 3 months.  Measurements of fatigue and cytokines were performed in all patients at the baseline and after the 3-month intervention

    Results

    Finally, information of 41 participants was used for data analysis. However, fatigue was decreased after supplementation than before, in the intervention group (P = 0.005). There was no significant difference (P = 0.090) between the change of fatigue score in the MVM group (-3.00 ± 4.42) and the control group (-0.40 ± 5.14). Among cytokines, Interleukin 4 (IL-4) significantly increased in the intervention group compared to the placebo (P = 0.030).

    Conclusion

    Our study showed that the present MVM probably could improve the inflammatory state and fatigue in patients with MS.

    Background

    Caregivers of patients with amyotrophic lateral sclerosis (ALS) may suffer from anxiety, depression, and reduced quality of life (QoL). Our goal was to evaluate the QoL and mood disorders in caregivers and their correlation with the patients' demographic, physical, and mental conditions.

    Methods

    We analyzed data from 39 patients with ALS and their caregivers. Patients completed questionnaires of anxiety assessed by Generalised Anxiety Disorder Assessment (GAD-7), depression using the Beck Depression Inventory-II (BDI-II), and QoL via 40-item Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ-40). Physical impairment was also measured in the patients using the revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R). Caregivers were also assessed by BDI-II, GAD-7, and 36-item Short-Form Health Survey questionnaire (SF-36).

    Results

    The prevalence of depression and anxiety in the patients was 82.1% and 71.8%, respectively. Caregivers also had higher rates of anxiety and depression and lower levels of QoL in comparison with the general population (anxiety: 66.7%, depression:  43.6%). Depression and anxiety were considerably associated with worsened QoL in the caregivers. None of the demographic, physical, or mental characteristics of patients with ALS were related to either mood status or QoL of the caregiver population.

    Conclusion

    Caregivers experience higher rates of anxiety and depression and lower QoL in comparison with the general population. The severity of mood disorders is inversely associated with the physical and mental domains of caregivers' QoL. Nonetheless, QoL in the caregivers is not affected by the physical or mental disability of the patients.

    Background

    Andsberg et al. have recently introduced a novel scoring system entitled “PreHospital Ambulance Stroke Test (PreHAST)”, which helps to early identification of patients with acute ischemic stroke (AIS) even in prehospital setting. Its validity has not been assessed in a study yet, and the purpose of this study was to assess this scoring system on a larger scale to provide further evidence in this regard.

    Methods

    This was a cross-sectional multi-center accuracy study, in which, sampling was performed prospectively. All patients over 18 years of age admitted to the emergency department (ED) and suspected as AIS cases were included. All required data were recorded in a form consisting of 3 parts: baseline characteristics, neurological examination findings required for calculating PreHAST score, and the ultimate diagnosis made from interpretation of their brain magnetic resonance imaging (MRI).

    Results

    Data from 805 patients (57.5% men) with the mean age of 67.1 ± 13.6 years were analyzed. Of all the patients presenting with suspected AIS, 562 (69.8%) had AIS based on their MRI findings. At the suggested cut-off point (score ≥ 1), PreHAST had a specificity of 46.5% [95% confidence interval (CI): 40.1%-53.0%) and a sensitivity of 93.2% (95% CI: 90.8%-95.2%).

    Conclusion

    According to the findings of our study, at the suggested cut-off point (score ≥ 1), PreHAST had 93.2% sensitivity and 46.5% specificity in detection of patients with AIS, which were somewhat different from those reported in the original study, where 100% sensitivity and 40% specificity were reported for this scoring system.

    Background

    Giant axonal neuropathy (GAN) is a very rare fatal neurodegenerative disorder with clinical and allelic heterogeneity. The disease is caused by mutations in the GAN (gigaxonin) gene. Herein, we reported the clinical presentations and results of genetic analysis of the first Iranian GAN case.

    Methods

    Phenotypic data were obtained by neurologic examination, brain magnetic resonance imaging (MRI), electromyography (EMG), electroencephalography (EEG), and sonography from the proband. Deoxyribonucleic acid (DNA) was isolated from peripheral blood leucocytes and whole exome sequencing (WES) was performed. The candidate variant was screened by Sanger sequencing in the proband and her family members.

    Results

    The proband was a 7-year-old girl who was admitted with a chief complaint of ataxia, muscle weakness, delayed developmental milestones, and history of psychiatric disorders. She was very moody and had clumsy gait, decreased deep tendon reflexes (DTRs) of lower limbs, and kinky hair. The brain MRI revealed white matter abnormality. The EMG revealed that her disease was compatible with the chronic axonal type of sensorimotor polyneuropathy; however, her EEG was normal. Results of the WES revealed a homozygous variant; c.G778T:p.E260* in the GAN gene, indicating the GAN disorder.

    Conclusion

    The present study affirmed GAN allelic heterogeneity and resulted in the expansion of the phenotypic spectrum of GAN pathogenic variants. Identification of more families with mutations in GAN gene helps to further understand the molecular basis of the disease and provides an opportunity for genetic counseling especially in the populations with a high degree of consanguineous marriage such as the Iranian population.

    Background
    Nowadays, many neurological conditions, including Parkinson’s disease (PD), are treated with deep brain stimulation (DBS). Life-threatening consequences can occur from DBS hardware failure or sudden implantable pulse generator (IPG) battery depletion. This issue may potentially worsen in concomitance with medical or infectious conditions, requiring stronger emergency management.
    Methods
    We present here a 58 year-old PD patient with DBS, whose IPG replacement surgery was complicated by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and we report management of this patient along with recommendations for patients with similar situation.
    Results
    As the newly-emerged coronavirus disease 2019 (COVID-19) is now announced to be pandemic, new protocols and specific measures for each individual group of patients with chronic diseases seem obligatory. Regarding our recent experience with a patient suffering from PD, on DBS treatment, who needed hospitalization, we felt useful to share our experience as a recommended protocol for similar patients in the time of current pandemic.
    Conclusion
    Close monitoring of laboratory and clinical signs should be warranted in patients with PD awaiting IPG replacement in order to be prepared in these novel conditions that may precipitate an akinetic crisis/dystonic storm and to prevent life-threatening complications during the current pandemic.

    Background

    This study aimed to compare the functional outcome of patients with malignant middle cerebral artery (MCA) infarction who had undergone either early decompressive craniectomy (DC) or optimal medical therapy (OMT).

    Methods

    This study was conducted during a 2-year period in Golestan Hospital of Ahvaz, Iran. The selected patients with malignant MCA infarction who were admitted within 48 hours of presenting signs were included. The patients were randomly assigned to undergo either early DC (n = 12) or OMT (n = 12) in the neurosurgical intensive care unit (ICU). The functional outcomes in the subjects were evaluated with the Glasgow Outcome Scale (GOS) and the National Institutes of Health Stroke Scale (NIHSS) at discharge, 6, and 12-month intervals.

    Results

    The patients who underwent DC had significantly higher GOS at discharge (P = 0.013), 6 (P = 0.022), and 12 (P = 0.042) months as compared to the medical therapy group. However, the NIHSS score did not show any significant difference between the two groups during the study. Likewise, DC was associated with lower mortality at 6 (P = 0.027) and 12 (P = 0.014) months; moreover, the lower mortality rate (P = 0.014), severe disability (P = 0.040), higher good recovery (P < 0.001), and moderate disability (P < 0.001) were observed after 12 months of follow-up.

    Conclusion

    These findings suggest that early DC in patients with malignant MCA can decrease mortality and improve the functional outcome according to GOS criteria compared to medical therapy.
