Filter by:The objective of this single-center retrospective observational study is to describe cognitive and psychological outcomes and their impact on quality of life after at least 3 months of intensive care unit (ICU) discharge in severe COVID-19 survivors.
Many post COVID-19 patients suffer from cognitive deficits, even after 1 year after hospitalization. These complaints have a huge impact on psychological well-being and quality of life. In rehabilitation programs in the Netherlands, most interventions are based on physical therapy or learning how to cope with fatigue and low levels of energy. In former studies computerized training of cognition in other populations has been proven to be effective. Knowledge on the effect of computerized training on attention and working memory in patients suffering from COVID-19 is urgently needed, and may contribute to more evidence-based rehabilitation programs for these patients. Therefore the effectiveness of computerized training of attention and working memory in post COVID-19 patients with cognitive complaints will be studied in this study.
The purpose of this study is to develop and test a comprehensive Brain Health Together program for older adults living with cognitive decline.
Inattentiveness and impulsivity in healthy adults and individuals with attention deficit hyperactivity disorder (ADHD) diminish these individuals' quality of life. Cortical hypometabolism has been hypothesized to contribute to inattentiveness in ADHD. Transcranial photobiomodulation (tPBM) is a safe and non-invasive modality for activation of the prefrontal cortex. tPBM in healthy adults has been shown to augment brain oxygenation, cognition, and mood. The cognition-enhancing effect of tPBM on sustained attention in adults with ADHD remains unstudied. The investigators will evaluate whether tPBM administration to adults with and without ADHD can improve their attention. Each participant will be screened for eighteen criteria based on the Diagnostic and Statistical Manual (DSM-IV, text revised), using the validated instrument Adult ADHD Self-Report Scale (ASRS-v1.1). Blinded participants will be randomized into (I) Active-tPBM or (II) Sham-tPBM groups. After undergoing an 8-minute administration of Sham or 1064 nm tPBM to the lateral and medial right prefrontal cortex, each participant will complete a 14-minute, computer-based Conner's continuous performance task-3 (CPT-3). The investigators will examine whether adults with and without ADHD who receive Active-tPBM improve in measures of inattention, impulsivity, sustained attention, or vigilance compared to the Sham-tPBM group. Cognitive assessments of attention like the CPT-3 may evaluate the efficacy of tPBM to increase cortical metabolism in healthy adults and individuals with conditions like ADHD. The investigators anticipate their investigation will be a starting point for more sophisticated studies that focus on the implications of tPBM on cognition.
This is a Phase 0, open-label, non-controlled, single-centre study designed to evaluate the pharmacokinetics (PK) and safety and tolerability of a single, bolus intravenous (iv) injection of a microdose of ACD856 in healthy subjects.
The goal of this observational study is to determine the impact of the combined use of cardiac rhythm recording devices, biomarkers, echocardiogram, and Magnetic Resonance Imaging (MRI) on the early detection of AF, silent stroke, and cognitive impairment in subjects older than 65 years at high risk. The main questions it aims to answer are: - The early detection of AF, allowing the establishment of preventive measures, will avoid its main complications, especially strokes and cognitive impairment or dementia, in patients at high risk? - Will cardiac rhythm monitoring devices be useful in the early detection of AF in patients at high risk? Participants will undertake an initial evaluation through an echocardiogram (to detect atrial dysfunction), cranial MRI (to detect silent strokes), plasma/serum collection to determine biomarkers, and a complete clinical assessment (including electrocardiogram, and scales for measurement of cognitive and functional status). The clinical evaluation will be repeated every 6 months and will allow the recording of the date of occurrence of the study events. In addition, annually, patients will be subjected to cardiac rhythm monitoring by electronic devices with the aim of improving AF detection.
The prevalence of Attention Deficit/ Hyperactivity (ADHD) varies between 3 and 10% depending on the studies. Comorbidities are frequently associated, in particular anxiety disorders. School, social and family consequences of ADHD can be major, especially in the presence of a comorbidity. The study goal is to evaluate, through questionnaires, the effect of self-hypnosis via a smartphone application, on the symptoms of inattention and anxiety in children with ADHD in addition to their treatment by methylphenidate. Parents and children complete the study questionnaires four times. - T0: at inclusion - T1 (T0+6 weeks): after 6 weeks of using the self-hypnosis application 5 days out of 7 for group 1 in parallel with the usual treatment / after 6 weeks of usual treatment for the group 2 - T2 (T0+8 weeks): after a wash-out period of 2 weeks (usual treatment only) for both groups - T3 (T0+14 weeks): after 6 weeks of use of the self-hypnosis application 5 days out of 7 for group 2 in parallel with the usual treatment / after 8 weeks of usual treatment for the group 1, following the 6 weeks of use of the application.
Stroke is the leading cause of long-term disability with an increasing incidence, especially in young adults. Among the cognitive difficulties following brain damage, deficits in attention are frequent and pervasive, affecting between 46% and 92% of stroke survivors. The current project targets patients with acquired brain injury, including stroke, traumatic brain injury, and brain tumor. The main objective of this study is to evaluate the use and the efficacy of a training program targeting attention and executive function difficulties, using gamified and digitized versions in virtual reality of standard cognitive exercises for patients with brain lesions.
Attention Deficit Hyperactivity Disorder (ADHD) is a very common neurodevelopmental disorder in childhood characterized by short attention span, impulsivity and hyperactivity. It is also known that sensory integration problems are seen together with the basic symptoms of ADHD. Studies indicate that children with ADHD have difficulties in perceiving and processing sensory stimuli, and in relation to this, they have difficulty in producing appropriate sensory responses at school, at home and in social environments. However, it was observed that the interventions related to ADHD did not focus on the sensory-motor dimension enough, and focused more on cognitive or social skills. Although current research indicates the presence of sensory integration disorder in children with ADHD, there are no studies showing the effectiveness of sensory integration intervention. Our study was planned to examine the effect of Ayres Sensory Integration intervention on sensory-motor, cognitive, behavioral skills and social participation in children with ADHD. Materials and Methods: After the evaluation, 90 children with ADHD will be included in the study by dividing them into intervention (n=45) and control (n=45) groups by simple randomization method. Ayres Sensory Integration Therapy intervention will be applied to the intervention group for 10 weeks, 3 times a week, with a session duration of 1 hour, while the control group will continue the drug treatment and after a waiting period of 10 weeks, Ayres Sensory Integration Therapy will be applied after the second evaluation. Participants, Sensory Profile (SP), Sensory Integration and Praxis Test (SIPT), Emotion Regulation Checklist (ERC), Stroop Test TBAG Form (Stroop TBAG), Childhood Executive Functions Inventory (CHEXI), Participation and Environment Scale for Children and Adolescents (PEM-CY), Conners Teacher Rating Scale (CTRS), Conners Parent Rating Scale (CPRS), Bruininks-Oseretsky Motor Proficiency Test-2 (BOT-2) and Goal Achievement Scale (GAS) both before and before intervention. and post-group change as well as between-group differences will be evaluated.
Insomnia is a common sleep disorder. In recent years, the incidence of insomnia is increasing worldwide. Studies point out that insomnia plays an important role in the pathogenesis of cognitive impairment. Although sleep and cognitive scales are the main methods to detect sleep quality and cognitive changes, there are problems such as strong subjectivity and poor repetition. There is an urgent need to use non-invasive and objective detection methods to assess the potential mechanisms of cognitive impairment caused by sleep disorders. Previous studies have shown that different brain states may show different neurovascular coupling (NVC) characteristics. However, after prolonged sleep deprivation, the evoked hemodynamics response was attenuated despite an increased electroencephalogram (EEG) signal response, suggesting that sustained neural activity may reduce vascular compliance. It is suggested that sleep disorder may lead to NVC disorder. However, whether sleep disorders regulate the mechanism of cognitive impairment in the brain through NVC disorders has not been demonstrated in vivo. Currently, functional magnetic resonance imaging (fMRI) can be used to study brain function and blood flow changes non-invasively. In our previous research, we combined cerebral blood flow (CBF) with mean amplitude of low-frequency fluctuation (mALFF), mean regional homogeneity (mReHo) and degree-centrality (DC), the early warning effect of fMRI features based on neurovascular uncoupling on early cognitive impairment was confirmed, providing a basis for further selection of functional imaging indicators. In conclusion, the present study proposes the scientific hypothesis that neurovascular decoupling-based MRI features are more appropriate for exploring the neural mechanisms underlying sleep disorders-induced brain cognitive impairment. The aim of this study is to establish an early warning and monitoring system for early non-invasive diagnosis and intervention of sleep-related cognitive impairment.
