Chorea-acanthocytosis (ChAc) is a rare autosomal recessive neurodegenerative disorder characterized by a variety of involuntary movements, predominantly chorea, and the presence of acanthocytosis in peripheral blood smears. ChAc is caused by mutations in the vacuolar protein sorting-associated protein 13A (VPS13A) gene. The aim of the present study was to conduct a clinical and genetic analysis of five patients with suspected ChAc in Iran.

The present descriptive research was carried out on the basis of data obtained from the Safe Implementation of Treatments in Stroke (SITS) registry on Iranian intravenous thrombolysis ischemic stroke cases.

Background And Objectives: COVID-19-related inflammation, endothelial dysfunction, and coagulopathy may increase the bleeding risk and lower the efficacy of revascularization treatments in patients with acute ischemic stroke (AIS). We aimed to evaluate the safety and outcomes of revascularization treatments in patients with AIS and COVID-19.
Methods: This was a retrospective multicenter cohort study of consecutive patients with AIS receiving intravenous thrombolysis (IVT) and/or endovascular treatment (EVT) between March 2020 and June 2021 tested for severe acute respiratory syndrome coronavirus 2 infection.
Background And Objectives: Declines in stroke admission, IV thrombolysis (IVT), and mechanical thrombectomy volumes were reported during the first wave of the COVID-19 pandemic. There is a paucity of data on the longer-term effect of the pandemic on stroke volumes over the course of a year and through the second wave of the pandemic. We sought to measure the effect of the COVID-19 pandemic on the volumes of stroke admissions, intracranial hemorrhage (ICH), IVT, and mechanical thrombectomy over a 1-year period at the onset of the pandemic (March 1, 2020, to February 28, 2021) compared with the immediately preceding year (March 1, 2019, to February 29, 2020).

Data in this regard are scarce in the Middle Eastern region. The present retrospective study was performed on data extracted from the Safe Implementation of Treatments in Stroke (SITS) registry.

Methods: This multicenter study included consecutive stroke patients with and without COVID-19 treated with IV-tPA between February 18, 2019, to December 31, 2020, at 9 centers participating in the CASCADE initiative. Clinical outcomes included modified Rankin Scale (mRS) at hospital discharge, in-hospital mortality, the rate of hemorrhagic transformation.
Background: The COVID-19 pandemic led to profound changes in the organization of health care systems worldwide.
Aims: We sought to measure the global impact of the COVID-19 pandemic on the volumes for mechanical thrombectomy, stroke, and intracranial hemorrhage hospitalizations over a three-month period at the height of the pandemic (1 March-31 May 2020) compared with two control three-month periods (immediately preceding and one year prior).
Methods: Retrospective, observational, international study, across 6 continents, 40 countries, and 187 comprehensive stroke centers.
Background And Aims: Alteration in the insulin signaling could contribute to the development of Alzheimer's disease (AD) through metabolic or inflammatory processes, adipokines could affect insulin dysregulation. This study aimed to investigate whether there is a correlation between serum adiponectin level alteration and insulin resistance with the presence and severity of AD, compared to normal controls.
Methods: This analytical observational study was conducted on 60 non-overweight and non-diabetic participants who were assigned to AD patients (n = 34) and healthy volunteers (n = 26).
Background: The prevalence of multiple sclerosis (MS) varies in different geographical regions and has dramatically increased in Iran. Revealing the high prevalence rate draws the attention of policymakers and helps them allocate necessary resources. The aim of this study is to determine the prevalence of MS in Zanjan province of Iran.

This study examines the changes in stroke epidemiology and care during the COVID-19 pandemic in Zanjan Province, Iran.
Methods: This study is part of the CASCADE international initiative.

Background And Purpose: The novel severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), now named coronavirus disease 2019 (COVID-19), may change the risk of stroke through an enhanced systemic inflammatory response, hypercoagulable state, and endothelial damage in the cerebrovascular system. Moreover, due to the current pandemic, some countries have prioritized health resources towards COVID-19 management, making it more challenging to appropriately care for other potentially disabling and fatal diseases such as stroke. The aim of this study is to identify and describe changes in stroke epidemiological trends before, during, and after the COVID-19 pandemic.

Although the vitamin D plays a role in the structure of vessels, the association between the serum level of vitamin D and subclinical atherosclerosis has not been well-studied. We aimed to investigate the association between serum vitamin D level and carotid artery intima-media thickness (CIMT) in Iranian population.

Visfatin (VIS), an adipokine secreted from peripheral adipose tissue, is involved in energy balance and weight control. Besides its metabolic roles, VIS possesses insulin-mimetic, anti-apoptotic, and neuroprotective properties.
