OBJECTIVE The decrease in verbal fluency in patients with Parkinson's disease (PD) undergoing subthalamic nucleus deep brain stimulation (STN-DBS) is usually assumed to reflect a frontal lobe-related cognitive dysfunction, although evidence for this is lacking. METHODS To explore its underlying mechanisms, we combined neuropsychological, psychiatric and motor assessments with an examination o...
This study compares semantic (category) and letter-initial verbal fluency performance in dementia of frontal lobe type, dementia of Alzheimer type, and control subjects matched for age, sex, and level of education. As well as demographic characteristics, patients were matched for severity of dementia as estimated by the mini mental scale (23.2 (SD 4.9)). All patients with dementia of frontal lo...
Studies have shown that number line estimation is important for learning. However, it is yet unclear if number line estimation predicts different mathematical skills in different grades after controlling for age, non-verbal cognitive ability, attention, and working memory. The purpose of this study was to examine the role of number line estimation on two mathematical skills (calculation fluency...
of a dissertation at the University of Miami. The current study examined cognitive effects of unilateral subthalamic nucleus (STN) deep brain stimulation (DBS) in Parkinson's disease (PD) patients. Neuropsychological evaluations were conducted at baseline and follow-up. Data was collected from 28 unilateral STN DBS patients (15 English-and 13 Spanish-speaking), and 15 English-speaking matched P...
Children with reading difficulties often demonstrate weaknesses in working memory (WM). This research study explored the relation between two WM systems (verbal and visuospatial WM) and reading ability in a sample of school-aged children with a wide range of reading skills. Children (N = 157), ages 9-12, were administered measures of short-term memory, verbal WM, visuospatial WM, and reading me...
Studies have demonstrated that in verbal fluency tests, monolinguals with Alzheimer's disease (AD) show greater difficulties retrieving words based on semantic rather than phonemic rules. The present study aimed to determine whether this difficulty was reproduced in both languages of Spanish/English bilinguals with mild to moderate AD whose primary language was Spanish. Performance on semantic ...
Stroop's test and the Verbal Fluency test are commonly argued to be measures of the integrity of the prefrontal cortex. This assumption has only to some degree been confirmed by lesion studies. In the present study, Positron Emission Tomography (PET) with H(2)(15)O was used to further validate Stroop's test and the Verbal Fluency as measures of frontal lobe function; both tests were implemented...
Objective To evaluate the discriminative and diagnostic values of neuropsychological tests for identifying schizophrenia patients. Methods A cross-sectional study with 36 male schizophrenia outpatients and 72 healthy matched volunteers was carried out. Participants underwent the following neuropsychological tests: Wisconsin Card Sorting test, Verbal Fluency, Stroop test, Mini Mental State Exami...
