Introduction: Psychotropic medication (PM) use in behavioral-variant frontotemporal dementia (bvFTD) is higher than in other dementias. However, no information exists on whether PM use differs between sporadic and genetic bvFTD.

Methods: We analyzed data from sporadic and genetic bvFTD participants with PM prescriptions in the Advancing Research and Treatment in Frontotemporal Lobar Degeneration/Longitudinal Evaluation of Familial Frontotemporal Dementia Subjects study.

The Clinical Dementia Rating Sum of Boxes (CDR-SB) is a staging scale for Alzheimer's disease (AD) and is commonly used as an outcome in clinical trials. It relies on information provided by the patient and an informant. The CDR-SB should reflect only the patient's disease severity.

Background: The Clinical Dementia Rating Sum of Boxes (CDR-SB) is used to stage dementia severity; it is one of the most common outcome measurements in Alzheimer's Disease (AD) research and clinical trials. The CDR-SB requires an informant to provide input to stage a patient's dementia severity. The effect of the informant's characteristics on the CDR-SB is unknown.

Area-level factors may partly explain the heterogeneity in risk factors and disease distribution. Yet, there are a limited number of studies that focus on the development and validation of the area level construct and are primarily from high-income countries. The main objective of the study is to provide a methodological approach to construct and validate the area level construct, the Area Level Deprivation Index in low resource setting.

The aim of this review was to map the literature on the double burden of malnutrition (DBM) among women of reproductive age (WRA) and preschool children in low- and middle-income countries (LMICs). The study aimed to provide an understanding of how DBM construct has been defined in the current literature and to elucidate plausible mechanisms underlying DBM development and its common risk factor among the two subgroups. We systematically searched for literature from the following databases: EMBASE, CINAHL, MEDLINE, LILACS, Scopus and ProQuest Dissertations & Thesis Global and identified articles that specifically reported on the coexistence of undernutrition and overnutrition sequalae at the population, household, or individual levels among WRA and preschool children in LMICs.

Introduction: The majority of the populations in low-income and middle-income countries (LMICs) are encountering the double burden of malnutrition (DBM): the coexistence of both undernutrition and overnutrition sequalae. With DBM being a new phenomenon in research, little is known about its aetiology, operational definitions and risk factors influencing its manifestation. The proposed scoping review is aimed at mapping literature with regard to the DBM phenomenon among preschool children and women of reproductive age in LMICs who are among the most high-risk groups to encounter DBM.

Background: Preliminary evidence suggests that patients with atrial fibrillation (AF) detected after stroke (AFDAS) may have a lower prevalence of cardiovascular comorbidities and lower risk of stroke recurrence than AF known before stroke (KAF).

Objective: We performed a systematic search and meta-analysis to compare the characteristics of AFDAS and KAF.

Methods: We searched PubMed, Scopus, and EMBASE for articles reporting differences between AFDAS and KAF until June 30, 2021.

Introduction: The underlying pathophysiology of atrial fibrillation (AF) detected after stroke (AFDAS) is relatively unknown. Preliminary evidence suggests AFDAS has a lower prevalence of cardiovascular comorbidities and higher incidence of insular cortex involvement than AF known to exist before stroke occurrence (KAF). This favours a neurogenic AF substrate (autonomic dysregulation) in which the presence of underlying heart disease is not necessary for AF to occur.

Thrombi identified on echocardiography at the time of straddling a patent foramen ovale (PFO) constitute a medical emergency with an associated imminent risk of death.  Ischemic stroke (IS) and myocardial infarction (MI) occurring in patients with a thrombus straddling a PFO (TSPFO) may be associated with increased risk of in-hospital death. Variables associated with increased risk of death in women and men may be different.

Article Synopsis
  • The study examined how the COVID-19 pandemic affected code stroke activations, stroke unit admissions, and referrals to a stroke prevention clinic in a large hospital in Ontario, Canada.
  • Researchers found a 20% decrease in code stroke activations in 2020 compared to 2019, occurring right after COVID-19 cases were confirmed, while stroke admissions remained stable.
  • The decrease in code strokes was primarily due to patients' fears of COVID-19 exposure, whereas the drop in clinic referrals was linked to hospital policies and government lockdown measures.

Spontaneous cervico-cerebral artery dissection (CCAD) is a common condition found among young patients with ischemic stroke. We examined the possible association between the polymorphism of methylenetetrahydrofolate reductase (MTHFR)-C677T and the gene mutation in transforming growth factor beta receptor II (TGFBR2) in a cohort of CCAD patients. One-hundred CCAD cases (65 males; mean age: 38.

Background And Purpose: Few studies have investigated the rates of recanalisation after cerebral venous thrombosis (CVT). Our objective was to investigate the recanalisation rate and to identify predictors of recanalisation in patients with CVT.

Methods: We included 102 patients with confirmed first-ever, non-septic CVT.
