Abstract
The endocannabinoid system (ECS) is an intricate network consisting of receptors, enzymes, and endogenous ligands that play a pivotal role in various neurological processes. It has been implicated in the pathophysiology of several neurological disorders, including epilepsy. Extensive research has demonstrated the involvement of genetic factors in influencing the susceptibility to and progression of epilepsy. In this study, we focused on investigating the connection between genetic variations in genes related to the ECS and the occurrence of epilepsy. Some ECS-related gene variants were selected and genotyping was performed using the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) technique. Interestingly, CNR1 rs12720071 genotype (OR 16.33, 95% CI 1.8-149; p = 0.001) showed an association with generalized epilepsy and MGLL rs604300 genotype (OR 2, 95% CI 1.1-3.4; p = 0.013) demonstrated a relationship with females diagnosed with focal epilepsy. So, studying CNR1, MGLL, and their genetic variations provides insights into the role of the endocannabinoid system in health and diseases. Moreover, they hold the potential to pave the way for the development of novel therapeutic approaches specifically targeting them.

Abstract
Key biomarkers such as Brain Derived Neurotrophic Factor (BDNF) and Neurofilament light chain (NfL) play important roles in the development and progression of many neurological diseases, including multiple sclerosis, Alzheimer's disease, and Parkinson's disease. In these clinical conditions, the underlying biomarker processes are markedly heterogeneous. In this context, robust biomarker discovery is of critical importance for screening, early detection, and monitoring of neurological diseases. The difficulty of directly identifying biochemical processes in the central nervous system (CNS) is challenging. In recent years, biomarkers of CNS inflammatory response have been identified in various body fluids such as blood, cerebrospinal fluid, and tears. Furthermore, biotechnology and nanotechnology have facilitated the development of biosensor platforms capable of real-time detection of multiple biomarkers in clinically relevant samples. Biosensing technology is approaching maturity and will be deployed in communities, at which point screening programs and personalized medicine will become a reality. In this multidisciplinary review, our goal is to highlight clinical and current technological advances in the development of multiplex-based solutions for effective diagnosis and monitoring of neuroinflammatory and neurodegenerative diseases. The trend in the detection if BDNF and NfL.

Abstract
Introduction: Warfarin is still the primary drug used to prevent vascular events in patientswith atrial fibrillation (AF), especially in low-income countries. Therapeutic failure and non-adherenceare common causes of recurrent embolic events. The aim of this study was toinvestigate possible reasons why INR was outside the therapeutic range in patients presentingwith acute ischemic stroke and AF. Methods: This prospective study was performed over a ten-month period and all patientsadmitted with acute ischemic stroke were enrolled. Patients with AF who did not have INRwithin the therapeutic range (INR = 2-3) at the time of admission were identified. During a face-to-face interview, the reasons for INR being outside the therapeutic range were assessed basedon a prepared checklist. Results: During the study period, 810 patients had an acute ischemic stroke, of which 177 hadAF heart rhythm (22%). The median age was 76 (IQR: 71-83), and 87 (52%) were male. Of these177 patients, 44 (25%) had a previous history of AF ("previous AF" group) and 133 (75%) werediagnosed with AF during the current hospital admission ("new AF" group). Among patients onwarfarin but with INR outside the therapeutic range (29 in all), 20 (69%) did not see a physicianregularly and/or did not take medication according to the physician’s instructions. Conclusion: The most common reason for INR being outside the therapeutic range was patientslack of awareness of their heart disease (unrecognized AF). Other reasons included irregularvisits to the physician and drug non-adherence.

Abstract
BACKGROUND The purpose of the study was to evaluate psychometric properties of the Persian version of the Patient-Weighted Quality of Life in Epilepsy Inventory-10-P (PV QOLIE-10-P). METHODS The Persian version was obtained from the original version by standard forward/backward translation. We assessed content validity, construct validity by factor analysis, internal consistency, test-retest reliabilities, criterion validity by calculating Pearson/Spearman correlation to the Persian version of the SF-36 inventory the Persian version of the 36-Item Short Form Health Survey (PV SF-36), and discriminant validity by calculating Pearson/Spearman correlation to demographic features and epilepsy-specific characteristics. RESULTS One hundred and fifty-five adult patients with epilepsy were enrolled in the study. The 10 items of PV QOLIE-10-P were grouped into two factors: epilepsy effects/role function scale (driving, work, social, memory, physical effect, and mental effect) and mental health scale (energy, depression, seizure worry, and overall quality of life). The Cronbach's alpha value was 0.859. Test-retest analysis revealed statistically significant correlations for total score and the scales (correlation coefficient for total score, epilepsy effects/role function, and mental health were 0.7, 0.66 and 0.7respectively). The Pearson correlation coefficient between total scores of the Persian version of QOLIE10-P and SF-36 was 0.822 (p < 0.001). The PV QOLIE-10-P was able to differentiate patients with marriage, education, job, seizure type, seizure frequency, and antiepileptic treatment. CONCLUSION The Persian version of QOLIE-10-P is a valid and reliable tool to assess the quality of life of patients with epilepsy in Iran.

Abstract
Background: Psychogenic non-epileptic seizures (PNES) are manifested as paroxysmal alterations in motor, sensory, autonomic, and/or cognitive and behavioral signs and symptoms, without associated ictal epileptiform discharges. A misdiagnosis of PNES as epilepsy results in a prolonged and unnecessary (antiepileptic) drug treatment and social and psychological stigma of epilepsy in these patients. This study aimed to determine the epidemiology, clinical manifestations, and associated factors of PNES in hospitalized patients in the video-electroencephalography (EEG) monitoring (VEM) service of Razi Hospital, Tabriz, Iran. Methods: In this cross-sectional descriptive study, 55 patients with a final diagnosis of PNES were selected from the patients referred to the VEM unit of Razi Hospital for the evaluation of epilepsy. The study was performed from May 2017 to June 2019. Patient information included demographic data and medical history (drug history, comorbidities, trauma, and family history). The clinical manifestations (semiology and duration of attacks) and EEG findings, as recorded by VEM during hospitalization, were collected. Results: 55 patients with PNES were studied with VEM, 27 (49.1%) of which were men, and 28 (50.9%) were women. The mean and standard deviation (SD) of age of the patients was 34.16 ± 12.64 years. No significant differences were observed in the semiology of PNES between men and women. Depression was the most common psychiatric comorbidity. Conclusion: The clinical manifestations of PNES in the present study were similar to those in most previous studies from other countries. The culture and sex of the patients did not seem to be a contributing factor in PNES semiology.

Abstract
Glutamate is considered as the predominant excitatory neurotransmitter in the mammalian central nervous systems (CNS). Alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) are the main glutamate-gated ionotropic channels that mediate the majority of fast synaptic excitation in the brain. AMPARs are highly dynamic that constitutively move into and out of the postsynaptic membrane. Changes in the postsynaptic number of AMPARs play a key role in controlling synaptic plasticity and also brain functions such as memory formation and forgetting development. Impairments in the regulation of AMPAR function, trafficking, and signaling pathway may also contribute to neuronal hyperexcitability and epileptogenesis process, which offers AMPAR as a potential target for epilepsy therapy. Over the last decade, various types of AMPAR antagonists such as perampanel and talampanel have been developed to treat epilepsy, but they usually show limited efficacy at low doses and produce unwanted cognitive and motor side effects when administered at higher doses. In the present article, the latest findings in the field of molecular mechanisms controlling AMPAR biology, as well as the role of these mechanism dysfunctions in generating epilepsy will be reviewed. Also, a comprehensive summary of recent findings from clinical trials with perampanel, in treating epilepsy, glioma-associated epilepsy and Parkinson's disease is provided. Finally, antisense oligonucleotide therapy as an alternative strategy for the efficient treatment of epilepsy is discussed.

Abstract
Neurological disorders, such as stroke, are triggered by a loss of neurons and glial cells. Ischemic stroke remains a substantial problem for industrialized countries. Over the previous few decades our understanding about the pathophysiology of stroke has enhanced, nevertheless, more awareness is required to advance the field of stroke recovery. Existing therapies are incapable to adequately relief the disease outcome and are not appropriate to all patients. Meanwhile, the majority of patients continue to show neurological deficits even subsequent effective thrombolysis, recuperative therapies are immediately required that stimulate brain remodeling and repair once stroke damage has happened. Cell therapy is emergent as a hopeful new modality for increasing neurological recovery in ischemic stroke. Numerous types of stem cells from various sources have been identified and their possibility and efficiency for the treatment of stroke have been investigated. Stem cell therapy in patients with stroke using adult stem cells have been first practiced in clinical trials since 15 years ago. Even though stem cells have revealed a hopeful role in ischemic stroke in investigational studies besides early clinical pilot studies, cellular therapy in human is still at a primary stage. In this review, we summarize the types of stem cells, various delivery routes, and clinical application of stem cell-based therapy for stroke treatment.

Abstract
Parkinson disease (PD) is known as a common progressive neurodegenerative disease which is clinically diagnosed by the manifestation of numerous motor and nonmotor symptoms. PD is a genetically heterogeneous disorder with both familial and sporadic forms. To date, researches in the field of Parkinsonism have identified 23 genes or loci linked to rare monogenic familial forms of PD with Mendelian inheritance. Biochemical studies revealed that the products of these genes usually play key roles in the proper protein and mitochondrial quality control processes, as well as synaptic transmission and vesicular recycling pathways within neurons. Despite this, large number of patients affected with PD typically tends to show sporadic forms of disease with lack of a clear family history. Recent genome-wide association studies (GWAS) meta-analyses on the large sporadic PD case-control samples from European populations have identified over 12 genetic risk factors. However, the genetic etiology that underlies pathogenesis of PD is also discussed, since it remains unidentified in 40% of all PD-affected cases. Nowadays, with the emergence of new genetic techniques, international PD genomics consortiums and public online resources such as PDGene, there are many hopes that future large-scale genetics projects provide further insights into the genetic etiology of PD and improve diagnostic accuracy and therapeutic clinical trial designs.

Abstract
We present a rare case of focal cortical dysplasia (FCD) and nonconvulsive status epilepticus (NCSE) treated successfully with early surgical intervention. Our case is a 9-year-old boy whose seizures, characterized by short episodes of loss of consciousness, appeared at the age of 7, and he showed progressive cognitive decline in the following years. NCSE was diagnosed, and his MRI revealed FCD in the left frontal region which was the same side as his EEG abnormality. Following lesionectomy, his NCSE disappeared and cognitive functions improved. Histopathologic analysis of the resected tissue revealed type-IIB FCD. This case illustrates the importance of early surgery to help restore cognitive functions by eliminating the clinical and electrophysiological features of NCSE. Focal cortical dysplasia is a well-recognized etiology of drug-resistant epilepsy in the pediatric population. Nonconvulsive status epilepticus (NCSE) may rarely develop in children with epilepsy due to focal cortical dysplasia. While NCSE is difficult to treat, early intervention is crucial for the prevention of cognitive decline. Early surgery is very important in children with nonconvulsive status epilepticus if an epileptogenic focus can be found.

Abstract
Percutaneous transluminal angioplasty (PTA) has recently become a noteworthy treatment option for significant stenosis involving the vertebral artery (VA) in selected patients. We conducted a prospective study to evaluate the efficacy, safety and mid-term follow up results of 206 cases received PTA with or without stent implant to treat their symptomatic atherosclerotic VA stenosis in all segments (V1-V4). In a prospective mono-arm trial from October 2008 to July 2012 in a single center, 239 lesions affecting the intra or extracranial VA (171 in V1, 17 in V2, 14 in V3, 21 in V4 and 16 in combined segments) were treated by PTA with or without stent implant. Non-disabling stroke patients who had failed conservative medical treatment and had angiographic evidence of >50% stenosis in the dominant VA with clinical signs and symptoms of VB stenosis were included in this study. They were mean followed for 13.15±5.24 months after treatment. Overall, 206 patients underwent the procedure. A stent was implemented in 199 patients (96.6%). The periprocedural complication rate was 7.2%. The procedural (technical) success rate was 97.6%. Of the total 239 lesions, 223 were treated with stent implant. Clinical success was achieved in all 206 symptomatic patients after the procedure. Restenosis occurred in 15.9% after a mean 10.8 (6-24) months. Of those, 63.1% and 34.2% had mild and moderate stenosis that was treated medically, whereas one case (2.6%) with severe restenosis underwent balloon angioplasty. No deaths occurred during the follow-up period. The follow-up complication rate was 6.3%. TIA occurred in 4.4%, a minor stroke in 1.4% and a major stroke in one patient. The overall patient event-free survival was 92.4%. These results demonstrate the safety and feasibility of PTA with or without stent implant, with a high technical success rate, a low complication rate, a low restenosis rate and durable clinical success in patients with symptomatic VA stenosis. This approach seems to improve patients' immediate and mid-term clinical results. Randomized controlled trials are necessary to further validate this treatment option.
