Abstract Background The verbal fluency task is a widely used psychometric test to account for cognitive functions, particularly, verbal and executive functions. Being an easy and fast test to administer, it is a good neuropsychological tool in low technology environments. Our objective was to analyze the performance in verbal fluency of Spanish-speaking children with neurodevelopmental disorders. Methods We performed a retrospective cross-sectional study to analyze the performance of children who had undergone a verbal fluency test in a neuropsychological assessment.

Abstract The Semantic Verbal Fluency (SVF) test entails the generation of words from a given category within a pre-set time of 60 seconds. Objectives: To verify whether socio-demographic and clinical data of individuals with dementia correlate with the performance on the SVF test and to ascertain whether differences among the criteria of number of answers, clusters and data spread over the intervals, predict clinical results. Methods: This was a retrospective study of 49 charts of demented patients classified according to the Clinical Dementia Rating (CDR) scale. We correlated education, age a

ABSTRACT. Semantic verbal fluency (SVF) is one of the most widely used tests for cognitive assessment due to its diagnostic utility (DU). Objective: our objective is to evaluate the DU to detect cognitive impairment (CI) of a short version of the SVF applied in 30 seconds (SVF1-30). Methods: a prospective sample of consecutive patients evaluated in a Neurology Unit between December 2016 and December 2017 were assessed with the Global Deterioration Scale (GDS), 30-second and 60-second SVF tests (animals), and the Fototest, which includes a fluency task of people’s names.

This study aimed to describe the performance of PD patients and an age- and education-matched control group on executive function, verbal fluency, and oral diadochokinesia tests and to investigate possible relationships between them.

Abstract Objective The semantic, logopenic, and nonfluent/aggramatic variants of primary progressive aphasia (PPA) have distinct clinical profiles. However, much overlap exists and many questions remain regarding the nature of language impairments in each variant. This case study seeks to contribute to our understanding of the neuropsychological profile, syntactic, and phonological processes involved in logopenic variant PPA (lvPPA). Method The current case study was of a 66-year old female who gradually developed symptoms consistent with lvPPA during the prior four-year period, with marked wo

Abstract Background Cross-linguistic information about performance in neuropsychological verbal tests is extremely scarce. It has been suggested that verbal fluency test using animal fluency test is one of the few tests fulfilling the fundamental criteria desirable in a robust neuropsychological test. Objective To compare and establish cross-linguistic information about performance in the animal fluency test. Results In an extensive search, it was found that norms for the semantic fluency test using the category ANIMALS are available in 15 different languages. These languages represent a relat

Aim: Considering the data on the important role of verbal fluency tasks in neuropsychological diagnosis and the models of hemispherically specialised modulation of processes essential for different types of verbal fluency, we made an attempt to identify differences in correct and incorrect performance of 5 verbal fluency tasks between patients with vascular cerebral pathology, including hypertension, and healthy individuals. We also analysed task performance profiles within the groups. Materials and methods: The study included healthy volunteers (n = 36), hypertensive individuals (n = 33), and

Abstract:

Previous literature in cognitive psychology has provided data involving differences in language processing between men and women. It has been found that women are usually more proficient with certain semantic categories such as fruit, vegetables and furniture. Men are reported to be better at other categories semantic, e.g. tools and transport. The aim of this article is to provide an inquiry about possible differences in semantic category processing of living things (LT) and inanimate objects (IO) by Argentinian Spanish-speakers school-aged children.

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) in individuals with Parkinson's disease (PD) has often been associated with reduced verbal fluency performance. This study aimed to directly assess semantic switching as a function of STN stimulation in PD participants with the Homophone Meaning Generation Test (HMGT). Seventeen participants with PD who had received STN DBS completed the HMGT in on and off stimulation conditions. Twenty-one non-neurologically impaired participants acted as controls. PD participants (in both on and off stimulation conditions) generated significantly

Abstract Objective To examine baseline differences in neuropsychological performance between long-term stable mild cognitive impairment (sMCI) and those who convert from MCI to dementia (cMCI), hypothesizing sMCI will perform better on memory measures. While conversion has been previously examined, none examined sMCI with over 10 years follow-up. Method Data from the National Alzheimer’s Coordinating Center were used. Participants were defined as sMCI (n = 29) if cognitive status was MCI at first visit and at least 9 subsequent visits (10 total) and cMCI (n = 1887) if cognitive status was MCI

The contribution of perceptual and semantic processing deficits to naming-test performance by Alzheimer's Disease subjects was examined. Groups of 34 Alzheimer subjects and 25 elderly controls completed tests of naming standard line drawings and naming perceptually degraded figures, and a test of verbal fluency for a specific semantic category. Alzheimer subjects were impaired on all measures and, when their naming-test errors were analyzed, they showed higher proportions of perceptual errors and failures to respond. Further, considerable variability in the proportions of different types of er

We have previously shown that aerobic exercise improves measures of verbal fluency in older adults, and such an improvement is correlated with improved cardiovascular reserve (i.e., estimates of VO2). Due to increasing popularity in computer-based cognitive training, we explored whether the addition of cognitive training to aerobic exercise would further enhance the beneficial cognitive impact of exercise. Therefore, this study sought to test the hypothesis that a cognitive training regimen alone would directly improve executive function and that this effect would be potentiated with the addit

Abstract:

AbstractObjectives: Mild cognitive impairment is common in non-demented Parkinson disease patients (PD-MCI) and is considered as a risk factor for dementia. Executive dysfunction has been widely described in PD and the Verbal Fluency Tests (VFT) are often used for executive function assessment in this pathology. The Movement Disorder Society (MDS) published guidelines for PD-MCI diagnosis in 2012. However, no investigation has focused on the qualitative analysis of VFT in PD-MCI. The aim of this work was to study the clustering and switching strategies in VFT in PD-MCI patients. Moreover, thes
