Filter by:The main cognitive complaint in brain-injured patients is often the everyday disorganization caused by Executive Function (EF) deficits. EF deficits are often seen in patients with psychiatric disorders i.e. depression or anxiety. In order to minimize everyday disorganization, effective EF interventions are required. Interventions using compensatory strategies have the potential to enable patients to minimize disabilities, minimize participation problems and to function more independently in daily life. A well-known evidence-based intervention that uses compensatory strategies is Goal Management Training (GMT), a training that has been found to alleviate depressive symptoms in a depressed population. GMT entails learning and applying an algorithm, in which a daily task is subdivided into multiple steps to handle executive difficulties of planning, and problem solving. To adopt the GMT strategy and ensure maximal profitability for patients, they have to learn to use the algorithm in different situations and tasks. Therefore, GMT is comprehensive, time-consuming and thus labour-intensive. Along with this, brain games become increasingly attractive as an (add-on) intervention, most notably in an effort to develop home-based personalized care. Until now, however, the rationale behind brain games is based on what can be considered the restorative approach (i.e. strengthening of executive problems) rather than practicing compensatory strategies, with little or no transfer to improvements in daily life functioning. This study therefore aims to assess the potential of a newly developed Brain Game, based on compensatory strategies, as an add-on to GMT to develop a shortened and partly self-paced GMT intervention. The primary objective of this study is to assess whether the use of a compensatory brain game supported GMT treatment could be of interest in people with EF deficits after ABI that also suffer from depression or anxiety, to improve goal achievement, their executive function performance during goal-related tasks, and their executive performance during an ecological valid shopping task. Also we assess whether psychological symptoms alleviate following the GMT intervention and at 6-weeks follow-up. The study will be a multiple-baseline across individuals single-case experimental design (SCED). The study population consists of brain-injured patients, between 18 and 75 years old that receive in-patient mental neuropsychiatric healthcare. Participants eligible for the study must have EF deficits due to (nonprogressive) Acquired Brain Injury (ABI), minumum time post-onset of 3 months and depressive or anxiety symptoms. EF deficits will be assessed by extensive neuropsychological examination. Participants will be recruited from an inpatient clinic. In the course of one and a half year four participants will be recruited.
Advances in prenatal and neonatal care have improved outcomes in children with severe congenital heart disease (CHD). With the increase in survival, neurocognitive problems such as executive functioning (EF) impairments have become more apparent in these children. EF problems have cascading negative effects on a child's development. New insights in EF development suggest that in otherwise physically healthy young children, EF can be improved by training. In a pilot study funded by Stichting Hartekind, the investigators studied the feasibility of a personalized EF training program called 'Kleuter Extra' and the results were promising. Therefore, the current study will investigate the effectiveness of this program in 4-6-year-old children with severe CHD. The researchers will also explore interactions between the parent-child relationship and EF development of the child as psychosocial difficulties in these children and their parent(s) and/or caretaker(s) may impact EF-development. If found effective, EF training for children with severe CHD will improve their developmental outcome.
The aim of the study is to examine the effect of VR application on motor, cognitive and sensory-perceptual skills, and activity and participation levels in children with DCD. The hypotheses on which the study proposal is based are as follows: 1. H0: VR application has no effect on motor skills in children with DCD. H1: VR application has an effect on motor skills in children with DCD. 2. H0: VR application has no effect on cognitive skills in children with DCD. H1: VR application has an effect on cognitive skills in children with DCD. 3. H0: VR application has no effect on sensory-perception skills in children with DCD. H1: VR application has an effect on sensory-perception skills in children with DCD. 4. H0: VR application has no effect on the functional independence levels in daily living activities in children with DCD. H1: VR application has an effect on the functional independence levels in daily living activities in children with DCD. 5. H0: VR application has no effect on participation levels in children with DCD. H1: VR application has an effect on participation levels in children with DCD.
The objective of this study is to analyze the effects of executive functions (EFs) and social-cognitive abilities on the associations between autistic traits and mental health indicators (depression, anxiety, and stress). Moreover, the study will produce online training modules for executive functions and social cognition, aimed at reducing the likelihood of adverse mental health outcomes in individuals with and without elevated autistic traits. Therefore, four main hypotheses will be addressed: 1. Revealing the mediating role of executive functions (cognitive flexibility, inhibitory control, and working memory) will help predict the association between autistic traits and mental health symptoms (anxiety, depression, and stress). 2. Revealing the mediating role of social cognitive skills (cognitive empathy and affective empathy) will help predict the association between autistic traits and mental health symptoms (anxiety, depression, and stress). 3. Online training in executive functions and social cognitive skills will help develop executive functions (working memory, inhibitory control, and cognitive flexibility) and social cognitive skills (cognitive empathy and affective empathy) in the current sample. 4. Online training in executive functions and social cognitive skills will promote mental health by reducing distress, depression, and anxiety symptoms in the current sample. Participants will be between the ages of 18-35 because previous findings indicate that the age of onset of various mental health problems is between the ages of 17 and 35. Participants will be randomly assigned to the experimental and control groups. Using a longitudinal design including pre-test, post-test, and follow-up conditions to test the effectiveness of combined EFs and social cognition online training for mental health symptoms.
Working memory (WM) is the ability to hold relevant information in mind in the absence of sensory input. The capacity for WM is a foundation for cognitive control and higher cognitive function more broadly. Previous research demonstrated that during the delay period of WM tasks, oscillatory electrical activity in the prefrontal cortex in the theta-frequency band (4-8 Hz) increased in amplitude. However, other groups found that the slope of the aperiodic signal in the brain was positively correlated with individual differences in WM capacity. Since low-frequency power and a steeper slope of the aperiodic signal are confounded in many analyses, it is not clear whether the slope of the aperiodic signal or the amplitude of low-frequency oscillations underlie WM capacity. With many studies investigating the causal role of theta oscillations in WM, the purpose of this project is to investigate the role of the aperiodic signal in WM performance.
The goal of this interventional study is to assess the effects of either physical exercise program or combined with cognitive training (dual motor and cognitive training program) on breast cancer survivors. The main questions it aims to answer are: - Analyze the effectiveness of a supervised dual-task training program or a physical exercise program on the executive functions of the participants. - Evaluate the impact of both interventions on physical function, emotional aspects, and important biomarkers related to muscle-brain crosstalk. Participants will perform a 20-week supervised and controlled program, three times a week, along with weekly calorie and step challenges. Researchers will compare the dual-task training group, with the physical exercise group, and with a control group, which will perform the guideline recommendations of physical activity (non-supervised) to see how these intervention approaches can impact cognitive functions, physical functions, emotional aspects, and biomarkers related to muscle-brain crosstalk. Assessments will take place at three-time points: at baseline, after the intervention (20 weeks post-baseline) and after a 12-week follow-up period (32 weeks post-baseline).
The goal of this clinical trial is to evaluate an evidence-based, non-pharmacological treatment alternative: Goal Management Training (GMT) for adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD). The main questions we aim to answer are: 1. Is GMT more effective than Treatment as Usual (TAU) in improving executive functioning in adolescents with ADHD? 2. Is GMT more effective than TAU in improving emotional health and social functioning in adolescents with ADHD? 3. Which clinical or cognitive characteristics are associated with treatment response? 4. Do medication, age, gender, and functional status at intake influence treatment response and long-term outcomes? 5. Are genetic (e.g. polygenic risk scores) and brain imaging data (e.g. estimates of brain maturation based on structural MRI or resting-state functional magnetic resonance imaging (fMRI) brain connectivity) relevant clinical predictors for treatment response and long-term outcomes?
The goal of this 13-year follow up of a randomized control trial is to study the effect of maternal choline supplementation on offspring cognition in adolescence. The main question[s] it aims to answer are: Does a higher dose of maternal choline choline (930 mg/d day supplementation) lead to improved cognition in adolescence including hippocampal-dependent episodic memory and executive functioning when compared to lower dose supplementation (480 mg/d). In this follow-up of a clinical trial participants will complete online cognition testing and emotion testing.

Participants eligible for the study must have executive deficits due to Acquired Brain Injury (ABI) of nonprogressive nature (i.e. TBI, stroke), with a minimum time post-onset of 3 months. Age has to be between 18 and 75 and participants have to live independently at home. Executive deficits will be assessed by extensive neuropsychological examination. Participants will be recruited from the outpatient clinic and the department of neurorehabilitation of Klimmendaal and Vogellanden. Four participants will be recruited.
The goal of this observational study is to explore if different and specific profiles can be identified in adults with binge eating disorder (BED) depending on their additional eating pathology, emotion regulation and executive functions. The main questions it aims to answer are: - Is there different and specific subgroups of patients with BED according to baseline profiles in emotion regulation, executive function and additional eating pathology (including restriction, chaotic eating, grazing and eating on external cues)? - Are subgroups of individuals with BED (based on identified profiles) associated with outcome at end of treatment and follow-up? - What is the trajectories in remission rates of specific symptom dimensions (eating disorder pathology, emotion regulation, executive function, and depressive symptoms) in individuals with BED and is there specific trajectory profiles in these dimensions? - Is early changes in specific symptom dimensions (eating pathology, emotion regulation, executive function, or depression) associated with outcome of BED? Participants will be asked to fill in questionnaires before treatment as usual, 10 weeks into treatment, at end of treatment and at 6- and 12-month follow-up.
