Headache Department, Iranian Center of Neurological Research, Neuroscience Institute, Tehran University of Medical Sciences, Tehran, Iran.

Introduction: In recent decades, studies have addressed the issue of how migraine and obesity are related and have suggested obesity as a risk factor for migraine headache. However, the exact direction of this relationship remains under debate. In this review, the authors summarize the evidence that have suggested migraine as a risk factor for obesity and overweightness.

Article Synopsis
  • Late-onset multiple sclerosis (LOMS) affects about 5% of MS patients and poses unique diagnostic and treatment challenges, with a study focusing on Iranian patients revealing specific characteristics of this group.
  • In a study of over 20,000 MS records, only 321 were classified as LOMS, primarily affecting females (67%), with a prevalence of approximately 75 per 100,000 people, and most patients had a relapsing-remitting course.
  • Findings highlighted a notable higher incidence of primary progressive MS and greater disability in LOMS patients, suggesting that further research is needed to address existing knowledge gaps and improve treatment approaches.

Background: Identification of the seizure onset zone (SOZ) is a challenging task in epilepsy surgery. Patients with epilepsy have an altered brain network, allowing connectivity-based analyses to have a great potential in SOZ identification. We investigated a dynamical directed connectivity analysis utilizing ictal intracranial electroencephalographic (iEEG) recordings and proposed an algorithm for SOZ identification based on grouping iEEG contacts.

Introduction: Introduction: blood-brain-barrier perfusion characterization impaired in MS as some studies have shown recently but a comparison between perfusion parameters in contrast-enhanced and non-enhanced lesions not have been well documented. Pharmacokinetic quantitative parameters have obtained from dynamic contrast-enhanced in magnetic resonance imaging is a useful way to quantify blood-brain barrier permeability leakage.

Methods: MR examination was performed on 28 patients with Relapsing-remitted Multiple Sclerosis (RRMS) with (Mean±SD age: 34.

Medically refractory seizures affect one-third of patients with epilepsy (PwE), for whom epilepsy surgery is considered. Video electroencephalography (vEEG) monitoring is a fundamental tool for pre-operative seizure localization. Facial and cranial myogenic artifacts can obscure vEEG findings, thus interfering with seizure localization.

Purpose: Investigations of the hemodynamic changes of the venous system in patients with multiple sclerosis (MS) have shown contradictory results. Herein, the biomechanical parameters of the internal jugular vein (IJV) and common carotid artery (CCA) of MS patients were extracted and compared to healthy individuals.

Methods: B-mode and Doppler sequential ultrasound images of 64 IJVs and CCAs of women including 22 healthy individuals, 22 relapsing-remitting multiple sclerosis (RRMS) patients, and 20 primary-progressive multiple sclerosis (PPMS) patients were recorded and processed.

As a benign isolated and encapsulated tumor originating from the nerve sheaths, schwannomas rarely appear on the cranial nerves, among which infraorbital nerve schwannomas are highly uncommon. We report a case of isolated infraorbital nerve schwannoma in a 58-year-old male patient with a clinical manifestation of proptosis in the affected eye.

The Dialogue Between Neuroinflammation and Adult Neurogenesis: Mechanisms Involved and Alterations in Neurological Diseases.

Mol Neurobiol

February 2023

Network of Immunity in Infection, Malignancy and Autoimmunity (NIIMA), Universal Scientific Education and Research Network (USERN), Tehran, Iran.

Adult neurogenesis occurs mainly in the subgranular zone of the hippocampal dentate gyrus and the subventricular zone of the lateral ventricles. Evidence supports the critical role of adult neurogenesis in various conditions, including cognitive dysfunction, Alzheimer's disease (AD), and Parkinson's disease (PD). Several factors can alter adult neurogenesis, including genetic, epigenetic, age, physical activity, diet, sleep status, sex hormones, and central nervous system (CNS) disorders, exerting either pro-neurogenic or anti-neurogenic effects.

Sarcopenia is more common in the elderly and causes adverse outcomes with increased morbidity and mortality. This prospective cohort study assessed the association of sarcopenia risk with the severity of COVID-19 at the time of admission and during hospitalisation and the length of hospital stay. Two hundred patients (aged ≥ 60 years) who were hospitalised for COVID-19 were enrolled using consecutive sampling between 29 December 2020 and 20 May 2021.

Article Synopsis
  • The study investigates the link between thyroid hormone (TH) levels and Alzheimer's Disease (AD) by comparing serum and cerebrospinal fluid (CSF) TH levels in AD patients and healthy controls.
  • Out of 1604 studies, 32 were analyzed, revealing significantly lower levels of serum total T3 and free T3, as well as lower CSF total T3 in AD patients compared to controls, while other thyroid hormones showed no significant differences.
  • The findings suggest that decreased T3 levels may be associated with AD, but further research is needed to understand the timing of these hormone changes in relation to the disease's progression.

Introduction: Multiple sclerosis (MS) is a chronic neurological disease in which demyelination and loss of axons lead to disruption of communication between neurons in the central nervous system. Cognitive impairment occurs in a significant proportion of patients with MS. Therefore, the aim of this study was to investigate the relationship between retinal nerve fiber layer (RNFL) thickness and corpus callosum atrophy in magnetic resonance imaging with memory disorders in patients with MS.

Background: Exercise has been demonstrated to be safe and well-tolerated in individuals with multiple sclerosis (MS). Physical activity has been shown to enhance the therapeutic effects of transcranial direct current stimulation (tDCS). This study aimed to determine the efficacy of intermittent tDCS combined with riding a stationary bicycle to improve walking capacity in individuals with MS.

Background: Door-to-needle (DTN) is the duration between patient's arrival at the hospital and receiving intravenous thrombolysis in ischemic stroke settings, for which studies have reported delays in women. The "D's of stroke care" describes 8 steps (D1 to D8) in patients' time tracker. We implemented simple modifications to the "D's of stroke care" by splitting D4 and D6 steps into these substeps: patients' arrival to the emergency room (D4-A), early assessment by a neurologist (D4-B), neurologist decision on patient's eligibility to receive recombinant tissue plasminogen activator (D6-A), and patient's transfer to the stroke unit (D6-B).
