Sedentary behaviours and cognitive function among community dwelling adults aged 50+ years: Results from the Irish longitudinal study of ageing
2020
Background:\ud \ud Sedentary behaviours (SB) are risk factors for poor cardiovascular health and all-cause mortality. However, their role in cognitive health in older adults is unclear. A few studies have examined associations between sedentary behaviours and cognition, but are limited by heterogeneity and insufficient longitudinal analyses. Therefore more robust studies, which would address identified limitations, are needed to accurately determine associations.\ud \ud Method:\ud \ud This study analysed data collected from participants aged 50+ years of The Irish Longitudinal Study of Ageing (TILDA). We conducted cross-sectional linear regression with multivariate imputation analyses of ba…
Examining the Efficacy of an Intervention to Improve Fluency and Reading Comprehension in Spanish Children with Reading Disabilities
2011
The main goal of the present study was to examine the efficacy of a multi‐component programme to improve reading fluency and text comprehension in Spanish children with reading disabilities (RD). Special needs teachers were trained in the application of the programme, which included repeated reading plus phonological awareness training and grapheme–phoneme decoding training. Instruction was delivered one to one. Participants were 22 students with RD, aged 10–13, distributed in two groups: one with 12 children who received the intervention (experimental group), and the other with 10 children who received no intervention (comparison group). The effects of the training programme were evaluated…
Associations of Sleep Quality, Anxiety, and Depression with Cognitive and Executive Functions among Community-Dwelling Women Aged 65 ≥ Years: A Cross…
2021
Background: The objective of this study was to evaluate the associations of sleep quality, anxiety, and depression with cognitive performance, executive functions, and verbal fluency among women aged ≥ 65 years. Methods: A cross-sectional study was conducted on 241 women (72.52 ± 3.93 years). Cognitive performance (Mini-Mental State Examination) and impairment (Montreal Cognitive Assessment), verbal fluency (Isaacs test) and executive function (Trail Making Test), Sleep quality (Pittsburgh Sleep quality Index) and anxiety and depression (Hospital Anxiety and Depression Scale) were determined. Results: The linear regression analysis indicated that anxiety, depression and age, were related to…
Rapid serial naming: relations between different stimuli and neuropsychological factors.
2004
We report two studies on rapid serial naming (RSN). Study 1 addressed the relations among RSN tasks comprising different stimuli. Separate components for RSN of alphanumeric and non-alphanumeric stimuli, as well as for tasks in which the stimuli alternated between categories were identified. In Study 2, phonological skills, processing speed, motor dexterity, and verbal fluency were found to explain RSN performance. The studies indicate: (1) that RSN tasks vary in their properties according to the stimuli used and according to the way the tasks are arranged, and (2) that RSN tasks are multi-componented.
Counting and RAN: Predictors of arithmetic calculation and reading fluency.
2013
This study examined whether counting and rapid automatized naming (RAN) could operate as significant predictors of both later arithmetic calculation and reading fluency. The authors also took an important step to clarify the cognitive mechanisms underlying these predictive relationships by controlling for the effect of phonological awareness and verbal short-term memory. Due to rather strong covariance between verbal short-term memory and phonological awareness, short-term memory could be controlled only partially. Participants, 200 children from a longitudinal study, were followed from age 5 to 10 years. Structural equation modeling showed counting to be a strong predictor, not only of lat…
Brain-predicted age difference score is related to specific cognitive functions: A multi-site replication analysis
2021
Abstract Brain-predicted age difference scores are calculated by subtracting chronological age from ‘brain’ age. Positive scores reflect accelerated ageing and are associated with increased mortality risk and poorer physical function. To date, however, the relationship between brain-predicted age difference scores and specific cognitive functions has not been systematically examined. First, applying machine learning to 1,359 T1-weighted MRI scans, we predicted the relationship between chronological age and voxel-wise grey matter data. This model was then applied to MRI data from three independent datasets, significantly predicting chronological age: Dokuz Eylul University (n=175), the Cogni…
Birth cohort differences in cognitive performance in 75- and 80-year-olds: a comparison of two cohorts over 28 years.
2021
Abstract Objective To evaluate cohort differences in cognitive performance in older men and women born and assessed 28 years apart. Methods Data in this study were drawn from two age-homogeneous cohorts measured in the same laboratory using the same standardized cognitive performance tests. Participants in the first cohort were born in 1910 and 1914 and assessed in 1989–1990 (Evergreen project, n = 500). Participants in the second cohort were born in 1938 or 1939 and 1942 or 1943 and assessed in 2017–2018 (Evergreen II, n = 726). Participants in both cohorts were assessed at age 75 and 80 years and were recruited from the population register. Cognitive performance was measured using the Dig…
Resting state glucose utilization and the CERAD cognitive battery in patients with Alzheimer's disease
2004
The present study examined the cortical functional representation of neuropsychological domains in Alzheimer's disease (AD) using positron emission tomography (PET) and the neuropsychological assessment battery of the Consortium to Establish a Registry of Alzheimer's Disease (CERAD). Thirty patients with clinical probable AD and 10 elderly healthy controls underwent (18)FDG brain PET imaging during a resting state. Correlations between metabolic values and cognitive measures were determined using a region of interest analysis with NEUROSTAT (University of Michigan, USA) and a voxel-based analysis with SPM96 (Wellcome Department, London, UK). Specific correlations were seen between measures …
Dental care protocol based on visual supports for children with autism spectrum disorders
2015
Background : Subjects with Autism Spectrum Disorders (ASDs) have often difficulties to accept dental treatments. The aim of this study is to propose a dental care protocol based on visual supports to facilitate children with ASDs to undergo to oral examination and treatments. Material and Methods : 83 children (age range 6-12 years) with a signed consent form were enrolled; intellectual level, verbal fluency and cooperation grade were evaluated. Children were introduced into a four stages path in or der to undergo: an oral examination (stage 1), a professional oral hygiene session (stage 2), sealants (stage 3), and, if necessary, a restorative treatment (stage 4). Each stage came after a vi…
