Acquired brain damage is a topic of central interest in neuropsychology, since it allows us to understand the relationship between cognition, behavior and emotion with pathological brain functioning. On this occasion, we present a case with a cerebrovascular disease that, as a result of damage at the thalamic level, presents executive, emotional, linguistic, and memory disorders. This is a 52-year-old patient who presents signs and symptoms such as personal insouciance, lack of motivation to seek employment, problems regulating his behavior, among others. We analyze the case regarding the role of the thalamus in global brain functioning and the need to carry out a correct follow-up with the patient.

Calidad de vida en pacientes con enfermedad cerebrovascular evaluados en un hospital venezolano. Quality of life in patients with stroke evaluated in a Venezuelan hospital.
Objective: Determine the health related quality of life (HRQL) in patients with cerebrovascular disease (CVD) evaluated in the Internal Medicine outpatient service from the Hospital General Hospital del Sur “Dr. Pedro Iturbe” en Maracaibo, Venezuela.
Materials and Methods: A descriptive and cross-sectional study was conducted, with a non-experimental design. The sample was represented by the first 80 patients with a new onset episode of CVD evaluated in the outpatient service from this hospital; to assess HRQL, the Quality of Life Scale for Stroke 38 was used.
Results: Of the subjects evaluated, 53.8% were women, the overall age was 60.7±9.4 years. Ischemic stroke was the most frequent, while 67.5% of the subjects evaluated showed some degree of involvement in their HRQL, specially moderate (36.3%) and mild (27.5%) degree.
Conclusion: no differences in HRQL were evidenced according to stroke type, although in general evaluation the majority reported a mild to moderate HRQL affectation, the analysis by domain shows a greater involvement in social functions, basic activities and physical problems.

Retardo en la Llegada de Pacientes con Ictus Isquémico a un Hospital Terciario de Ecuador. Delay In The Arrival Of Ischemic Stroke Patients At A Tertiary Hospital In Ecuador.
Introduction. In an Stroke unit, the ischemic stroke treatment with a pharmacological thrombolysis is associated with a better recovery. The aim of this study is to identify the variables having a significant impact in the delay of the arrival of patients at a tertiary hospital. Methods. A prospective and longitudinal study was undertaken in patients with an ischemic stroke diagnosis, who were admitted to the Stroke Unit of Eugenio Espejo Hospital of Quito city in Ecuador in the time period from November 2016 to July 2017. Patients treated with r-Tpa were compared to those who arrived 4,5 hours later. Results. A total of 61 patients were analyzed: of those, 51 arrived 4,5 hours after first symptoms at the hospital, and 10 (16,4%) were thrombolysed in the period of therapeutic window. None of the social, demographic and clinical variables were related to the early arrival, except the history of an atrial fibrillation. In the group of patients who received r-Tpa, a significantly higher percent sought for medical care as a first option compared with those arriving after the 4,5 hours (90 vs 49%, p 0,0170). The greatest impact of the early referral and the thrombolysis concerned the difference of score between the initial medical evaluation and the hospital discharge in the NIHSS scale. Conclusions. The results of this study point out to the unawareness of the stroke and the behavior to follow. The r-Tpa treatment shows clear benefits to the patients in our environment.

El Proyecto Atahualpa, Protocolo, Definiciones Operacionales y Diseño Inicial. The Atahualpa Project: Protocol, Operational Definitions, And Initial Study Design
Non-communicable diseases are the new health epidemics in developing countries due to increased life expectancy, and changes in lifestyle and dietary habits of the population. The Atahualpa Project was designed as a multi-step population-based cohort study designed to reduce the increasing burden of these conditions in rural Ecuador. The first step of the study followed a 3-Phase design, aimed to get information on demographics and cardiovascular risk factors of Atahualpa residents aged ≥40 years, as well as to assess the prevalence of stroke and ischemic heart disease. During Phase I, participants were screened with standardized questionnaires to evaluate their cardiovascular health and to identify those with suspected stroke or ischemic heart disease. In Phase II, neurologists and cardiologists examined suspected cases of stroke or ischemic heart disease, as well as a random sample of matched negative individuals, to assess prevalence of these conditions. In Phase III, patients with diagnosis of stroke and ischemic heart disease underwent complementary tests for achieving more specific diagnosis. Implementation of public health strategies directed to improve the cardiovascular health status of a given population must be based on studies evaluating specific risk factors at regional levels. Epidemiologic surveys such as the Atahualpa Project may prove cost-effective for improving the cardiovascular health status of people living in Latin American rural villages by increasing the knowledge on the particular needs of these populations.

Deterioro Cognitivo: Prevalencia y Correlatos en una Comunidad Rural Ecuatoriana. Lecciones del Proyecto Atahualpa. Cognitive Decline: Prevalence And Correlates In A Rural Ecuadorian Community. Lessons From The Atahualpa Project.
Assessment of cognitive impairment in rural areas of developing countries is complicated by illiteracy and cross-cultural factors. The Montreal Cognitive Assessment (MoCA) was used to estimate cognitive performance in individuals enrolled in the Atahualpa Project. Some problems were noticed with the use of this test, including issues related to naming animals, as well as the need to adjust a different cutoff for diagnosing mild cognitive decline than that used in highly educated individuals living in developed countries. After correlating MoCA scores with neuroimaging signatures of cortical and subcortical atrophy, a cutoff of 19-20 points would better define cognitive impaired individuals in rural areas. We also noticed that severe edentulism as well as psychological distress were associated with poor cognitive performance in older adults living in Atahualpa. In contrast, our study showed a linear, and dose-dependent, direct relationship between dietary oily fish intake and cognitive performance. We also aimed to assess the independent contribution and the interaction of age, the stroke itself and diffuse subcortical damage in the poor cognitive performance observed in patients with stroke, and noticed that interaction of age and diffuse subcortical damage are major determinants for poor cognitive performance among stroke patients. The total cerebral small vessel disease score can be used as a reliable predictor of poor cognitive performance, although its predictive power is not better than that of isolated neuroimaging signatures of cerebral small vessel disease. Finally, we noticed an inverse relationship between calcium content in the carotid siphon – used as a surrogate of intracranial atherosclerosis – and cognitive performance in our population.

Prevalencia de Enfermedades Neurológicas no Transmisibles en una Población Rural del Estado de Chiapas, México: Protocolo y Resultados Basales. Estudio Pro-Mas (Proyecto Comunitario La Soledad)
Objective: We aimed to assess cardiovascular health and neurological status of community-dwelling adults living in “La Soledad,” Chiapas, México, to calculate prevalence and incidence of cerebrovascular diseases, epilepsy and cognitive decline. Among others, these conditions are currently considered as the new epidemics in rural.
Design: Following a protocol similar to that used for the Atahualpa Project, we conducted a two-phase epidemiological study. During phase I, La Soledad residents were interviewed with validated field instruments to assess cardiovascular health status and well as to detect suspected stroke, epilepsy and cognitive impairment patients. During phase II, trained physicians examined suspected individuals as well as a random sample of non-suspected individuals to assess prevalence of diseases of interest.
Comment: Public health strategies must be based on the study of region-specific risk factors. Studies such the Atahualpa Project were proven to be effective for the assessment of public health problems in a rural Ecuadorian village. PROMAS will likely be cost effective to increase current knowledge on these conditions in Mexican rural villages and to promote a better cardiovascular health status among their inhabitants.

Código Ictus: Protocolo de Tratamiento del Ictus Cerebral Isquémico
Cardiovascular diseases are the leading causes of mortality worldwide and Ecuador is not an exception. One of the great issues about these phenomena is the impact on vital organs such as the brain. Several features of cerebrovascular diseases, such as the high rate of associated disability and radiological advances, have encouraged the different government health institutions to establish standardized procedures, which are executed in order to generate an early diagnosis and individually analyze following procedures in affected patients. This article reviews the literature about CODE STROKE, which is a standardized approach performed in spaniards hospitals.

Cadena de supervivencia del Ictus: Un desafío de la medicina actual.
A quasi experimental study was carried out in patients with cerebrovascular disease, through the stroke survival chain at the Municipality Holguín, in order to characterize the access getting of these patients to the secondary care unit at the Hospital Provincial Docente V. I. Lenin, from May to October 2006. Neurological evaluation and cerebrovascular risk scales were applied, obtaining the following results: ages from 60 to 74 years were the more affected, predominantly in male. Atherotrombotic cerebral infarcts were the more frequent. Only 8 patients (23,5%) arrived to the hospital during the first three hours of the event. High blood pressure, history of cerebrovascular disease and cardiopathies were the more frequent risk factors. Glasgow coma scale above 11 points was observed in all the cases. We conclude that, in order to reestablish cerebral blood flow after stroke, it is necessary to participate in a whole performance survival chain.

Síndrome de Moyamoya en un niño con Drepanocitosis.
Sickle cell disease is one of the main causes of ischemic stroke in the childhood, generally related with stenosis of the arteries of the anterior carotid circulation. We present the results of the studies carried out in a patient with sickle cell with no history of stroke, in treatment with hidroxyurea. Transcraneal Doppler and Magnetic Resonance Imaging demonstrated the existence of stenosis in medial cerebral arteries and a Moyamoya pattern in the cerebral circulation with hemodynamic ischemic lesions.

Enfermedad Vascular Cerebral en los Trópicos
Objectives. To review the clinical manifestations, diagnosis, and therapy of diseases causing cerebrovascular disease (CVD) in the tropics. Development. Most prevalent conditions causing CVD in the tropics include: sickle cell disease, Takayasu’s arteritis, cysticercosis, infective endocarditis, Chagas’ disease, viral hemorrhagic fevers, gnathostomiasis, leptospirosis, snake bites, cerebral malaria, puerperal venous thrombosis, and tuberculosis. These conditions may cause cerebral infarcts or hemorrhages, and in most instances are related to either vascular damage secondary to angiitis or hemorrhagic diathesis with bleeding in other organs. In some patients, the severity of the neurological picture makes impossible to identify an specific stroke syndrome and cerebrovascular complications are only recognized on neuroimaging studies or autopsy. Conclusions. There is a group of tropical infectious and non-infectious diseases that may cause cerebral infarcts or hemorrhages. Prompt diagnosis and therapy are needed to reduce the severity or brain damage and to avoid recurrent strokes.

Epidemiología de la enfermedad cerebrovascular hemorrágica en la región central de Cuba
Introduction. Cerebrovascular diseases are the third most important cause of death in Cuba. Among the programmes given priority by the Cuban Ministry of Public Health and the World Health Organization (WHO), hemorrhagic disorders are the most ‘lethal’. Objective. To determine the ‘behaviour’ of hemorrhagic cerebrovascular disease in the central region of Cuba. Patients and methods. An exploratory, descriptive, retrospective study in which 1,401 clinical histories were reviewed. The variables being investigated were then processed using the computer data processor EPINFO 6.0 to determine the mean, standard deviation and chi squared. Results. An annual incidence rate of 84.03 per 100,000 persons was seen for hemorrhagic cerebrovascular disease; 54.16 and 29.86 per 100,000 persons respectively for intracerebral hemorrhage and subarachnoid hemorrhage; and total mortality of 68.95%. The disorder was associated with possible meteorological factors and the highest percentage was due to intracerebral hemorrhage with 64.45%. Arterial hypertension was the most intensely studied risk marker (p< 0.01). Most cases were elderly (p< 0.001). Surgical treatment was given to 81 patients with subarachnoid hemorrhage, with a predominance of malformations of the middle and anterior cerebral arteries. Treatment was based on depletion using Manitol and calcium antagonists. A considerable number of patients required mechanical ventilation and vaso-active drug support. Most were attended in Intermediate Polyvalent Treatment Units and the main complication was sepsis. Conclusions. There is a high mortality from hemorrhagic cerebrovascular disease in the central region of Cuba, and once the diagnosis has been made the prognosis is usually poor. The patients included in the programme of attention for subarachnoid haemorrhage showed promising results.
