Marital Stability During the Year After Traumatic Brain Injury in an Ecuadorian Sample: A Repeated-Measures Study.

Traumatic brain injury (TBI) is a major cause of death and disability worldwide and often leads to long-lasting emotional, physical, and cognitive changes and results in reduced functioning across multiple domains. These changes often lead to strain in marital relationships as the uninjured spouse grapples with adapting to the changes in their partner. The purpose of this study was to examine the probability of marital stability after TBI at 6 and 12 months following injury (i.

Impact of Educational Level on Versions (Basic and Complete) of the Montreal Cognitive Assessment.

Background: One of the most marked problems in the use of screening instruments for the diagnosis of dementia or cognitive impairment in the elderly is the influence of educational level on the results of psychometric tests. The Montreal Cognitive Assessment (MoCA) questionnaire is one of the most widely used dementia screening instruments internationally and with greater proven validity. There is a version of this instrument called MoCA "Basic" which was developed to reduce education bias.

Search for schizophrenia and bipolar biotypes using functional network properties.

Introduction: Recent studies support the identification of valid subtypes within schizophrenia and bipolar disorder using cluster analysis. Our aim was to identify meaningful biotypes of psychosis based on network properties of the electroencephalogram. We hypothesized that these parameters would be more altered in a subgroup of patients also characterized by more severe deficits in other clinical, cognitive, and biological measurements.

Event-related potentials associated to N-back test performance in schizophrenia.

Mapping of Event-Related Potentials (ERP) associated with auditory and visual odd-ball paradigms has shown consistent differences between healthy controls and schizophrenia patients. It may be hypothesized that higher task attentional/cognitive demand will result in larger differences in these paradigms, which may help understanding the substrates of cognitive deficits in this syndrome. To this aim, we performed an EEG study comparing the effects of increasing the attentional/cognitive load of an auditory N-back task on the Event-Related Potential in 50 subjects with schizophrenia (11 first episodes) and 35 healthy controls.

Behavioral and sociodemographic predictors of anxiety and depression in patients under epidemiological surveillance for COVID-19 in Ecuador.

A cross-sectional study was performed from March 22th to April 18th, 2020 using an online survey.

Normative data of neuropsychological tests of attention and executive functions in Ecuadorian adult population.

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]).

Normative Data for Test of Verbal Fluency and Naming on Ecuadorian Adult Population.

To generate normative data for verbal fluency and naming test in an Ecuadorian adult population. 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.

Regression-Based Normative Data for Children From Latin America: Phonological Verbal Fluency Letters M, R, and P.

This study is part of a larger project to generate norms for letter verbal fluency test (VFT) in 3,284 children from nine Latin American countries. The letter VFT (letters M, R, and P) was administered and multiple linear regressions, including age, age, MPE (mean parental education), MPE, sex, and interactions were used as predictors. Results showed significant differences across countries for all scores.

Multivariate Base Rates of Low Scores on Tests of Learning and Memory among Spanish-Speaking Children.

To determine the prevalence of low scores on two neuropsychological tests commonly used to evaluate learning and memory in children. 6,030 healthy children from 10 countries in Latin America and Spain were administered Rey-Osterrieth Complex Figure (ROCF) and the Test de Aprendizaje y Memoria Verbal-Infantil (TAMV-I). Results showed that low scores are common when multiple neuropsychological outcomes (tests and/or scores) are evaluated in healthy individuals.

Subchronic use of rivastigmine increases procognitive flexibility across multimodal behavioral tasks in healthy male rats.

Rivastigmine (RVT) is a reversible inhibitor of cholinesterase approved worldwide for the treatment of cognitive dysfunctions, especially in Alzheimer's disease. Most previous pre-clinical studies have examined the effects of RVT treatment in a wide variety of pathological research models. Nonetheless, the effects of this drug on sensorimotor gating, memory, and learning tasks in healthy subjects remains unclear.

[Relationship between subclinical psychotic symptoms and cognitive performance in the general population].

Introduction: Subclinical psychotic symptoms are associated to negative life outcomes in the general population, but their relationship with cognitive performance is still not well understood. Assessing the relationship between performance in cognitive domains and subclinical psychotic symptoms in the general population may also help understand the handicap attributed to clinical psychosis, in which these alterations are present.

Methods: Subclinical and cognitive assessments were obtained in 203 participants from the general population by means of the Community Assessment of Psychic Experiences, the Brief Assessment of Cognition in Schizophrenia, the Wechsler Adults Intelligence Scale and the Wisconsin Card Sorting Test.
