Publication Open Access Normative data of neuropsychological tests of attention and executive functions in Ecuadorian adult population(Routledge, 2021) Rodríguez Lorenzana, Alberto; Ramos Usuga, Daniela; Adana Díaz, Lila; Mascialino, Guido; Rivera, Diego; Ciencias de la Salud; Osasun ZientziakObjective: The purpose of this study was to generate normative data for five tests of attention and executive functions (M-WCST, Stroop test, TMT, BTA, and SDMT), in a group of 322 Ecuadorian adults from Quito between the ages of 18 and 85. Method: Multiple regression analyzes taking into account age, education, and gender were used to generate the normative data. Results: Age and education were significantly related to test performance such that scores decreased with age and improved as a function of education. An online calculator is provided to generate normative test scores. Conclusions: This is the first study that presents normative data for tests of executive functions and attention in an Ecuadorian adult population. This data will improve the clinical practice of neuropsychology and help to develop the field in the country.Publication Open Access Anxiety and depression in patients with confirmed and suspected COVID-19 in Ecuador(Wiley, 2020) Paz, Clara; Mascialino, Guido; Adana Díaz, Lila; Rodríguez Lorenzana, Alberto; Simbaña-Rivera, Katherine; Gómez-Barreno, Lenin; Troya, Maritza; Páez, María Ignacia; Cárdenas, Javier; Gerstner, Rebekka M.; Ortiz-Prado, Esteban; Ciencias de la Salud; Osasun ZientziakThe rapid spread of the novel coronavirus, SARS-CoV-2 throughout the world has forced local and national administrations to take unprecedented measures to reduce the impact of the coronavirus diseases (COVID-19) pandemic. In South America, the arrival of the virus took longer than in other regions of the world, nevertheless, the impact has already been unprecedent. For instance, Ecuador was one of the most affected countries by the pandemic, reported hundreds of deaths each day during the last weeks of March and the first weeks of April 2020. The mortality rates were high during these months due to late implementation of restrictive measures of social distancing and limited capacity of health services (testing capacities and contact tracing). In this scenario, the Ecuadorian Ministry of Public Health (MoPH) established an epidemiological surveillance program for COVID-19 confirmed and suspected patients. The Department of Mental Health at the MoPH in Ecuador lead an active surveillance of the emotional impact of the disease by deploying an online self-reporting tool among patients to identify needs and provide standard of care treatment. The authors of this study were asked to participate in the development of this survey. The tool recorded sociodemographic variables and responses from two questionnaires: the Patient Health Questionnaire (PHQ-9) to measure the presence and severity of depressive symptoms, and the Generalized Anxiety Disorder (GAD-7) to assess the presence and severity of anxiety symptoms.Publication Open Access Normative data for test of learning and memory in an Ecuadorian adult population(Routledge, 2020) Rodríguez Lorenzana, Alberto; Nuñez Fernández, Silvia; Adana Díaz, Lila; Mascialino, Guido; Rivera, Diego; Ciencias de la Salud; Osasun ZientziakObjective: The objective of this study was to develop norms for two neuropsychological tests of learning and memory in an Ecuadorian adult population. Method: 322 healthy individuals, ages between 18 and 84, were enrolled in the Metropolitan District of Quito. Participants were administered a comprehensive neuropsychological evaluation that included tests of learning and memory (Rey-Osterrieth Complex Figure Test [ROCF] and Hopkins Verbal Learning Test-Revised [HVLT-R]). Backward stepwise multiple linear regression analyses were used to examine the influence of demographic variables age, education, and gender on test performance. Normative data were developed adjusting for demographic variables found to be significant in the final regression models. Results: The final multiple linear models revealed performance on tests of learning and memory worsened with age and improved as a function of education. A user-friendly Excel-based calculator is presented to calculate the z score and percentile automatically based on raw score and sociodemographic information. Conclusion: This is the first study that presents normative data for tests of learning and memory for an adult population in Ecuador. It is expected that these norms will help to improve the clinical practice of neuropsychology in Ecuador by limiting erroneous raw score interpretation and incrementing diagnostic accuracy.Publication Open Access Nivel educativo y la autonomía funcional en adultos que residen en Quito (Ecuador)(Fundación Universitaria Konrad Lorenz, 2019) Adana Díaz, Lila; Cuadros-López, Alejandra; Andrango-Guerrón, Dilan; Rodríguez Lorenzana, Alberto; Yacelga Ponce, Tarquino; Loureiro, Clara; Ciencias de la Salud; Osasun ZientziakLa incapacidad funcional del adulto asociada al envejecimiento poblacional genera un problema de salud pública. El objetivo de este artículo es estudiar la asociación existente entre el nivel educativo y la autonomía funcional de los adultos del Distrito Metropolitano de Quito (DMQ) en Ecuador. Para ello se realizó un análisis secundario con la información de la base de datos del estudio “Montreal Cognitive Assessment (MoCA): datos normativos para la población ecuatoriana”, que tiene un diseño transversal con adultos de 45 a 85 años. Se utilizó un modelo multivariado de regresión logística. El tamaño muestral fue de 328 participantes, de los cuales 301 fueron incluidos. Los resultados muestran diferencias significativas en cuanto al nivel educativo y la autonomía funcional: primero, permiten observar que un nivel educativo igual o mayor a los 12 años de instrucción es un factor de prevención de la pérdida de la autonomía funcional; segundo, muestran que hay una mayor posibilidad de pérdida de autonomía en función de la edad. Esta asociación existente entre el nivel educativo y la preservación de la autonomía funcional en el adulto en el DMQ muestra la importancia de promover el acceso a prácticas educativas permanentes en la población como parte de un programa de prevención de la pérdida de la autonomía mencionada.Publication Open Access Behavioral and sociodemographic predictors of anxiety and depression in patients under epidemiological surveillance for COVID-19 in Ecuador(Public Library of Science, 2020) Paz, Clara; Mascialino, Guido; Adana Díaz, Lila; Rodríguez Lorenzana, Alberto; Simbaña-Rivera, Katherine; Gómez-Barreno, Lenin; Troya, Maritza; Páez, María Ignacia; Cárdenas, Javier; Gerstner, Rebekka M.; Ortiz-Prado, Esteban; Ciencias de la Salud; Osasun ZientziakEcuador has been one of the most affected countries by the Corona Virus Disease 19 (COVID-19) pandemic, by April 2020 this country presented the highest rates of mortality in Latin America. The purpose of the present study was to identify behaviors during confinement and sociodemographic variables associated with the mental health status of confirmed or suspected COVID-19 patients who were part of the epidemiological surveillance program in Ecuador that included mandatory confinement and self-isolation. A cross-sectional study was performed from March 22th to April 18th, 2020 using an online survey. The survey collected socio-demographic information and severity of depressive symptoms using the Patient Health Questionnaire-9 and anxiety symptoms through the Generalized Anxiety Disorder-7. A total of 759 patients completed the questionnaire, 20.3% presented moderate to severe symptoms of depression and 22.5% moderate to severe symptoms of anxiety. Being a woman and from the Coastal region were risk factors. Exercising, maintaining daily routines, and keeping informed about the COVID-19 but limiting to an hour was associated with better mental health. Regression analysis indicated that the mentioned behaviors explained approximately 17% of the variance for depression sum scores and 11.8% of the variance for anxiety sum scores while controlling for gender and region. Understanding the association between sociodemographic variables and psychological states in patients with COVID-19 is relevant to tackle future public mental health problems and to implement health policies that are intended to palliate further psychiatric complications. Promotion of modifiable behaviors such as exercising, maintaining daily routines, and keeping informed about the COVID-19 but limiting to less than an hour is recommended.Publication Open Access Normative data for test of verbal fluency and naming on ecuadorian adult population(Frontiers Media, 2020) Rodríguez Lorenzana, Alberto; Benito Sánchez, Itziar; Adana Díaz, Lila; Paz, Clara; Yacelga Ponce, Tarquino; Rivera, Diego; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun ZientziakObjective: To generate normative data for verbal fluency and naming test in an Ecuadorian adult population. Methods: The sample consisted of 322 healthy adults (18–84 years old) recruited from Quito, Ecuador. The verbal fluency and Boston Naming Test (BNT) were administered as part of a larger comprehensive neuropsychological battery. Multiple linear regression analyses were used to generate the normative data taking into account age, education, and sex. Results: For phonological verbal fluency, results indicated that only education was significantly related to the performance of the letters “A,” “S,” and “M.” However, the performance on the letter “F” was significantly associated with age and education. For semantic fluency, the performance on “animals” was significantly influenced by age, quadratic age, and education, whereas that for “fruits” was explained by quadratic age, education, and sex. The performance on the BNT was significantly influenced by age and education. A Microsoft Excel-based calculator was created to help clinicians to obtain the normative data on this test. Conclusion: This normative data will help neuropsychologist in Ecuador to use these tests both in research and in their clinical practice to improve the diagnosis of cognitive deficits in the population.
