Objective: Executive functions (EFs) are a multifaceted construct, important for several outcomes throughout life. The most commonly addressed executive components are inhibitory control, working memory, and cognitive flexibility. To map how other executive components are addressed conceptually and methodologically in the literature, a scoping review was carried out.

Recent studies suggest that Omeprazole, a widely used treatment for gastric acid-related disorders, may have a significant effect on human cognition. However, there is no consensus on the matter. Though some studies suggest the drug is associated with an increased risk of cognitive decline, memory impairment, and dementia, this issue has not been sufficiently studied.

Methods: A case-control study was developed with 44 omeprazole users (OU; 81.8 % female, 66 ± 8.
The inhibitory control is a component of the executive functions that allows the individual to inhibit inadequate behaviors, resist distractions and select a relevant stimulus when executing activities. In the neuropsychology field, evidences of stimulation and improvement of the inhibitory control through school interventions is sought by using computerized software, such as digital games. These research studies constitute an important investigation area within the executive functions in ecological approaches.

The program of neuropsychological stimulation of cognition in students: emphasis on EF, or PENcE (an acronym from its original name in Portuguese, ), is an early and preventive intervention program for school-aged children, and implemented at school three times a week for 5 months. The PENcE was structured in four modules, each focusing on a different executive component: organization and planning, inhibitory control, working memory, and cognitive flexibility.

Methods: The process has followed the recommended steps for creating neuropsychological instruments: internal phase of program organization, with literature search and analyses of available materials in the classroom; program construction; analysis by expert judges; data integration and program finalization. To determine the level of agreement among the judges, a Content Validity Index (CVI) was calculated.
Objective: To verify whether differences exist between groups of Brazilian adults aged 40-59 and 60-75 in respective performance on the Bells Test, given the dearth of literature investigating the relationship between focused visual attention and the age factor.
Methods: Eighty-four neurologically healthy adults (half aged 40-59 and half 60-75) with high educational level (40-59 years group: M=17.75 years' education; SD=4.

Objectives: To describe normative data for the Hayling Test and the Trail Making Test (TMT) in a sample of Brazilian adults, and to investigate the effects of age and education on test performance.
Method: A total of 313 (TMT) and 364 (Hayling) individuals with age ranges of 19-39, 40-59, and 60-75 years, and with at least 5 years of formal education, participated in this study. The tests were administered as part of a large battery of a normative project.
This systematic review aimed to characterize empirical studies on neuropsychological interventions to stimulate executive functions in children with typical development. Searches were conducted according to the PRISMA method. Nineteen (19) studies on the analysis to evaluate the effectiveness of intervention programs in pre-school and school children were obtained.

The Hotel Task is one of the most widely used ecological measures of executive functioning, and provides an assessment of planning, organization, self-monitoring and cognitive flexibility.
Objective: The goal of this study was to adapt the Hotel Task for use in the Brazilian population.

Unlabelled: Executive functions are involved in a series of human neurological and psychiatric disorders. For this reason, appropriate assessment tools with age and education adjusted norms for symptom diagnosis are necessary.
Objective: To present normative data for adults (19-75 year-olds; with five years of education or more) on the Modified Wisconsin Card Sorting Test (MWCST), Stroop color and word test and Digit Span test.
Although the frontal lobes have traditionally been considered the neural substrates of executive functioning (EF), recent studies have suggested that other structures, such as the cerebellum, may be associated with these abilities. The role of the cerebellum has only been sparsely investigated in connection with decision making (DM), an important component of EF, and the few results obtained on this front have been inconclusive. The current study sought to investigate the role of the cerebellum in DM by comparing the performance of patients with cerebellar strokes, frontal-damaged patients, and a healthy control group on the Iowa Gambling Task (IGT).
View Article and Find Full Text PDFAging has been associated with several brain changes that often affect the cognitive functioning of adults, but changes in executive functions, particularly in the field of decision making, have not been fully investigated. The Iowa Gambling Task (IGT) is a widely used tool to evaluate decision making, but little is known about the effect of age on its results. This study used the IGT and compared healthy young (n = 40) and elderly (n = 40) adults to evaluate their decision making processes.
