Semantic inhibition and dementia severity in Alzheimer’s disease

2019

Semantic inhibition is often found to be impaired in Alzheimer’s disease (AD). The sentence completion task (Hayling test) was used to investigate whether it would be useful for differentiating mild AD from moderate AD. Method: Latency responses and error scores in the automatic and inhibition parts of the test were registered in these two groups of patients and in a group of healthy older participants. The types of errors were also analysed. Group differences were analysed by ANOVA. In addition, relationships with other neuropsychological tests were reported. Results: Participants with moderate AD performed worse than controls in both the automatic and inhibition sections, whereas particip…

KIELELLINEN ERITYISVAIKEUS – EI PELKÄSTÄÄN KIELELLISTEN TAITOJEN ONGELMA

2016

Kielellisen erityisvaikeuden ajatellaan olevan ensisijaisesti kielellisten taitojen ongelma. On kuitenkin todennäköistä, että kielelliseen erityisvaikeuteen liittyy myös ei-kielellisiä vaikeuksia. Tämän artikkelin tavoitteena on luoda katsaus eksekutiivisiin toimintoihin ja prosessointinopeuteen osana kielellistä erityisvaikeutta. Tutkimusten perusteella näyttää siltä, että kielelliseen erityisvaikeuteen liittyy kognitiiviseen joustavuuteen, inhibitioon, työmuistiin, tarkkaavuuteen sekä prosessointinopeuteen liittyviä vaikeuksia ainakin osalla kielihäiriöistä lapsista. Kielellisen erityisvaikeuden kliinisessä diagnostiikassa ja kuntoutuksessa on syytä huomioida myös ei-kielelliset vaikeudet…

Deliberate Play and Preparation Jointly Benefit Motor and Cognitive Development: Mediated and Moderated Effects

2016

In light of the interrelation between motor and cognitive development and the predictive value of the former for the latter, the secular decline observed in motor coordination ability as early as preschool urges identification of interventions that may jointly impact motor and cognitive efficiency. The aim of this study was twofold. It (1) explored the outcomes of enriched physical education, centered on deliberate play and cognitively challenging variability of practice, on motor coordination and cognitive processing; (2) examined whether motor coordination outcomes mediate intervention effects on children’s cognition, while controlling for moderation by lifestyle factors as outdoor play h…

Relaciones entre Funciones ejecutivas y calidad de vida de jóvenes con trastorno por déficit de atención con hiperactividad (TDAH).

2015

ResumenAntecedentes y objetivos. Pocos estudios han analizado la contribución del funcionamiento ejecutivo (FE) a la calidad de vida (CAV) en sujetos con TDAH. Objetivos del trabajo: (1) Explorar las diferencias entre adultos con y sin TDAH en  calidad de vida (2) Comparar la calidad de vida entre adultos TDAH con y sin dificultades en funcionamiento ejecutivo (3) Analizar la influencia de los problemas en Funciones ejecutivasven la calidad de vida de adultos con TDAH. Métodología. 36 jóvenes con TDAH y 27 sin el trastorno cumplimentaron cuestionarios sobre calidad de vida y funcionamiento ejecutivo Resultados. Se hallaron diferencias estadísticamente significativas entre jóvenes TDAH con y…

Effects of assisted training with neurofeedback on EEG measures, executive function and mood in a healthy sample

2015

The training in neurofeedback (NF) consists of teaching individuals to modify, adjust and enhance their brain activity pattern. The aim of our research was to evaluate the effect of training on cognitive processes, specifically executive function, and mood in a non-clinical sample. A sample of 30 female college students were assigned to three groups: RH: right hemisphere (n = 10), LH: left hemisphere (n = 10) and control (n = 10). The dominance pattern of beta and the inhibition of the theta pattern were trained in a single session. Measures of executive function (Iowa Gambling Test) and questionnaires of mood were taken pre and post training. We found that NF training produced significant …

Automatic auditory and somatosensory brain responses in relation to cognitive abilities and physical fitness in older adults

2017

AbstractIn normal ageing, structural and functional changes in the brain lead to an altered processing of sensory stimuli and to changes in cognitive functions. The link between changes in sensory processing and cognition is not well understood, but physical fitness is suggested to be beneficial for both. We recorded event-related potentials to somatosensory and auditory stimuli in a passive change detection paradigm from 81 older and 38 young women and investigated their associations with cognitive performance. In older adults also associations to physical fitness were studied. The somatosensory mismatch response was attenuated in older adults and it associated with executive functions. So…

Relationship between cognitive performance and mobility over the life course

2018

We studied cross-sectional, longitudinal and temporal associations between executive function and life-space mobility in old age. We assessed the association between intellectual ability in early adulthood and physical functioning in old age, and the association between early life motor development and cognitive performance in early old age. The participants of the first dataset were 157 persons aged 76-91 y who were followed up for two years as part of the Life-Space Mobility in Old Age study, and who took part in measurements on executive function (EF) implemented with the Trail Making Test and Life-Space Assessment. The second dataset comprised persons from the Helsinki Birth Cohort Stud…

Bidirectional associations between cognitive functions and walking performance among middle-aged women

2022

Objective: This study investigated whether (1) cognitive functions change after the transition from the perimenopausal to the postmenopausal stage, (2) cognitive functions and walking are associated in middle-aged women, and (3) cognitive functions assessed in perimenopause are associated with walking after reaching the postmenopause or vice versa. Methods: In total, 342 women, categorized as early (n = 158) or late perimenopausal (n = 184), were included in the study and followed up until postmenopausal. Psychomotor speed, executive functions related to set-shifting and updating, working memory, and visual memory were assessed. Walking was assessed with walking speed, walking distance, and…

School-based group intervention in attention and executive functions: Intervention response and moderators

2022

ObjectiveThis study investigated the effects of a school-based skill-training intervention in attention control and executive functions for pupils with hyperactivity-impulsivity (H-I) and cognitive control (CC) deficits. The main aim was to examine whether the intervention differently influenced H-I and CC, and whether cognitive abilities or conduct problems moderated response to the intervention.MethodElementary school pupils from 41 schools participated the study and were divided into an intervention group (n = 71) and a waitlist control group (n = 77). Intervention outcomes were assessed with an inventory assessing executive function difficulties (including H-I and CC) completed by class…
