OBJECTIVE While Parkinson's disease (PD) has traditionally been defined by motor symptoms, many researches have indicated that mild cognitive impairment is common in non-demented PD patients. The purpose of this study was to compare verbal fluency performance in non-demented Parkinson's disease patients with healthy controls. METHOD In this cross-sectional study thirty non-demented Parkinson'...

UNLABELLED The present study investigated the Executive Functions (EF) of inhibition, mental flexibility and phonemic and semantic fluency in a 1-year follow-up assessment of patients diagnosed with first episode Major Depressive Disorder (MDD). In the acute phase, the patient group performed significantly poorer compared to the control group (CG) in inhibition and semantic fluency. The present...

PURPOSE To compare the performance of hearing-impaired and normal-hearing people on phonologic and semantic verbal fluency tests. METHODS A cross-sectional study was conducted with 48 hearing-impaired adults and 42 individuals (control group) with no hearing or language complaints. Sociodemographic data were collected, as well as the characteristics of hearing loss and of the electronic audit...

A category specific effect in naming tasks has been reported in patients with Alzheimer's dementia. Nonetheless, naming tasks are frequently affected by methodological problems, e.g., ceiling effects for controls and "nuisance variables" that may confound results. Semantic fluency tasks could help to address some of these methodological difficulties, because they are not prone to producing ceil...

The most used verbal fluency paradigms are semantic and letter fluency tasks. Studies suggest that these paradigms access semantic memory and executive function and are sensitive to frontal lobe disturbances. There are few studies in Brazilian samples on these paradigms. Objective The present study investigated performance, and the effects of age, on verbal fluency tasks in Brazilian children...

This study examined the impact of various degenerative dementias on access to semantic knowledge and the status of semantic representations. Patients with semantic dementia, primary progressive aphasia, and Alzheimer's disease were compared with elderly controls on tasks of category and letter fluency, with number of words generated, mean lexical frequency and errors recorded. The findings are ...

The hallmark of Alzheimer's disease (AD) is declarative memory loss, but deficits in semantic fluency are also observed. We assessed how semantic fluency relates to cortical atrophy to identify specific regions that play a role in the loss of access to semantic information. Whole-brain structural magnetic resonance imaging (MRI) data were analyzed from 9 Normal Control (NC)(M=76.7, SD=5.6), 40 ...

Verbal fluency test is a useful method to evaluate cognitive executive functions. Studies have shown that both types of verbal fluency test (phonemic and semantic) are influenced by brain damage. This test is rarely used by clinicians because it takes too much time to perform. Therefore, we decided to increase its speed and accuracy by designing a verbal fluency test application in Persian lang...
