Cerebral venous thrombosis is part of the so-called thrombosis in unusual sites. It is defined as an occlusion in the cerebral venous territory. Its incidence is progressively increasing, especially in developing countries. It is more frequently observed in young women, with hormonal factors such as pregnancy or hormonal contraception being significant risk factors in the development of this condition. The clinical presentation will depend fundamentally on the topography of the thrombosis, with a confirmatory diagnosis based mainly on imaging tests...

There are many factors involved in the incidence of Alzheimer’s disease that, in combination, impede or hinder normal neuronal functions. Little is currently known about calcium regulation before and during the disease. Internal instability of calcium levels is associated with increased vascular risk, a prevalent condition in a high number of individuals already compromised by Alzheimer’s disease. This review provides a reevaluation of the molecular mechanism of the sarcoendoplasmic reticulum calcium ATPase (SERC-A) in the disease and discusses salient aspects of voltage-gated calcium channel function; in these way new alternatives could be open for its treatment...

INTRODUCTION: Cardiovascular compromise in coronavirus disease 2019 (COVID-19) does not necessarily present with the classic symptoms described in myocarditis. There is growing evidence demonstrating subclinical cardiovascular compromise in the context of the intense inflammation unleashed, the cytokine storm involved, the baseline prothrombotic state, and the consequent endothelial dysfunction. We set out to analyse whether Troponin-T (TT) and the amino-terminal fraction of pro-brain natriuretic peptide (NT-proBNP) determined at hospital admission, are related to mortality during the hospitalization of these patients...

BACKGROUND: The pathogenesis of mild cognitive impairment (MCI) is multifactorial and includes the presence of genetic variants such as the ε4 allele of the apolipoprotein E gene (APOE-ε4 ). Association between the APOE-ε4 carrier status and deleterious structural and functional changes on magnetic resonance imaging (MRI) has been previously described in individuals with Alzheimer's disease. However, the central nervous system changes may possibly develop in earlier stages of cognitive impairment, as reflected in MCI...

INTRODUCTION: Moyamoya disease (MD) is a progressive, occlusive disease of the arteries of the anterior cerebral circulation that may cause ischaemia or haemorrhage. Patient management aims to prevent new cerebrovascular events through surgical revascularisation and/or pharmacological treatment. MATERIALS AND METHODS: We studied a series of 17 patients with MD (n = 14) or moyamoya syndrome (MS; n = 3), who were evaluated between January 1989 and December 2016; 11 patients were women and 6 were men...

The reversible cerebral vasoconstriction syndrome is a variable, segmental, and multifocal constriction of brain arteries, usually with a benign course. We describe the case of a 49-year-old woman who presented with headaches, visual symptoms, and seizures. Three days after admission, vasoconstriction areas were found in at least two vascular territories in two segments of the same arteries. The patient was admitted to the intensive care unit where her blood pressure was monitored and she received medical treatment...

Objetivo: Determinar la vida saludable perdida por hipertensión arterial sin diabetes mellitus. Método: La vida saludable perdida se determinó a partir de la discapacidad crónica (enfermedad renal crónica, cardiopatía y evento vascular cerebral), la discapacidad aguda (crisis hipertensiva y emergencia hipertensiva) y la muerte prematura. Se identificaron la edad del diagnóstico, la edad de la complicación, la prevalencia de la complicación, la duración del evento agudo, el número de eventos agudos, el tiempo vivido con hipertensión, la edad de la muerte y la esperanza de vida...

Angiosarcoma is the most malignant sarcoma originating in endothelial vascular cells. It has a wide differential diagnosis due to its similarities with other entities, such as parasitic diseases. More often, angiosarcoma is diagnosed by exclusion. Neurocysticercosis and hydatid disease, or echinococcosis, are parasitic infections that may involve the central nervous system and their incidence is higher in South American countries. Diagnosis is established based on the epidemiological profile, the parasitological examination, the radiological appearance of the lesions, and the histopathology analysis of specimens...

INTRODUCTION: Atherosclerotic carotid artery disease (CAD) is a major risk factor for cerebrovascular disease. OBJECTIVE: To analyze the association of major vascular risk factors with atherosclerotic CAD and white matter disease (WMD) in patients without a history of ischemic stroke. METHOD: Risk factors were assessed with carotid examination using Doppler duplex ultrasound. Cases with a history cerebral infarction or transient ischemic attack were not included...

Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a preventable cause of in-hospital death, and one of the most prevalent vascular diseases. There is a lack of knowledge with regards to contemporary presentation, management and outcomes of patients with VTE. Many clinically important subgroups (including the elderly, those with recent bleeding and pregnant patients) have been under-represented in clinical trials. Furthermore, design of clinical trials is challenging in some scenarios, such as in those with hemodynamically unstable PE...

INTRODUCTION: The absence of a consensus system for full neuropathological evaluation limits clinicopathological studies and comparability between laboratories. Combined staging for Alzheimer's type and cerebral vascular pathology may allow a better classification of cases for clinical and cognitive correlation. METHODS: Cognitive and postmortem neuropathological data were obtained from 70 brains donated to the Tissue Bank of the Centro de Investigación de Enfermedades Neurológicas (CIEN) Foundation according to recently developed staging schemes for Alzheimer's type and vascular pathology...

OBJECTIVE: To analyze the association between the admission systolic blood pressure (SBP) and 30-day outcome in patients with acute cerebrovascular disease. METHODS: The REgistro NAcional Mexicano de Enfermedad VAScular Cerebral (RENAMEVASC) is a hospital-based multicenter registry performed between November 2002 and October 2004. A total of 2000 patients with clinical syndromes of acute cerebrovascular disease confirmed by neuroimaging were registered. The modified Rankin scale was used for outcome stratification...

BACKGROUND AND OBJECTIVE: Data on implementation of stroke guidelines are scarce in Spain. We assessed the quality of diagnosis and prevention measures at discharge in patients admitted to hospital for acute cerebral infarction (ACI) in Spain. PATIENTS AND METHOD: Independent audit of clinical records on 1,448 consecutive patients admitted to Spanish hospitals for an ACI, performed in a stratified-random sample of 30 public Spanish hospitals. The number of records evaluated per hospital was adjusted by hospital size...
