Filter by:The goal of this clinical trial is to test adding choline to ready-to-use therapeutic food (RUTF) in children with severe acute malnutrition (SAM) in Malawi. The main question it aims to answer is: - Will the addition of a 500mg daily dose of choline to RUTF during treatment for SAM improve cognitive development among 6-59-month-old Malawian children compared with standard RUTF without added choline?
The goal of this intervention study is to test the effects of a nurse-led mobility intervention (known as the OASIS Walking Intervention (Older Adults performing Sit to Stands and Walking Intervention)) in older adults with cognitive impairment, such as dementia, in transitional care programs. The main questions this study aims to answer are: - Is the study doable and are older adults satisfied with the intervention? - Does the intervention improve older adults' muscle strength, mobility, functional status and quality of life? Participants will be asked to do the following: 1. Be interviewed once so that a patient-centred communication care plan can be made 2. Do sit to stand activity 3. Walk as part of a walking program.
To examine the effect of dance interventions on cognitive functions and quality of life in patients with chronic stroke.
This study will evaluate a new form of non-invasive deep brain therapy for individuals with Alzheimer's disease. Low-intensity transcranial focused ultrasound stimulation will first be delivered using a range of stimulation parameters during psychophysical and physiological monitoring. A well-tolerated stimulation protocol will be selected for subsequent testing in a blinded randomized sham-controlled cross-over trial. The trial will evaluate brain target engagement using magnetic resonance imaging, PET imaging, and numerical scales of cognitive performance.
Rhythmic physical exercise is a very promising non-pharmaceutical tool to prevent or reduce cognitive decline that occurs in people sixty years of age or older. The main objective is to determine the effect of a rhythmic exercise program on the physical, mental and cognitive performance of older adults with cognitive impairment. The main variables of the study will be: global cognitive function evaluated by the Mini Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA); attention and executive functions evaluated using the Trail Making Test (TMT) part A and B. As secondary variables, the functional abilities evaluated using the Senior Fitness Test (SFT) will be taken into account. Additionally, sociodemographic variables and variables related to health status will be evaluated. These will take into account the quality of sleep evaluated with the Pittsburgh index, the nutritional status evaluated using the Mini Nutritional Assessment-Short Form (MNA-SF) scale, and the Stress and anxiety levels will be assessed using the Depression Anxiety Stress Scales-21 (DASS-21). All variables will be evaluated before the intervention and after it. After the intervention, it is expected that the exercise program will improve the neurocognitive performance, as well as the functional and psychological abilities of older adults.
Purpose: Healthy aging is the process of optimizing opportunities for health, participation and safety in order to improve quality of life as people age. This study aimed to provide healthy aging for people with cognitive impairment through the use of the Nintendo Switch combined with Occupational Therapy sessions. Material and methods: a randomized clinical trial was conducted. The sample was randomized using a software program, OxMar, which allowed the separation of the sample into a control group (CG), which received their usual sessions of conventional occupational therapy, and an experimental group (EG), which received therapy with Nintendo Switch, plus their conventional occupational therapy sessions. An 8-week intervention was conducted with Nintendo Switch. Measures: Nine Hole Peg Test, Box and Block Test, Barthel Index, WHOQOL-BREF, CSQ-8.
The goal of this clinical trial is to investigate the effects of a three-week altitude-like cognition training intervention in healthy individuals (substudy 1) and symptomatically stable patients with mood disorders (depression or bipolar disorder; substudy 2). This multi-modal intervention consists of an adaptive cognitive training programme that participants complete while they're inside an altitude-training room with 12% O2, corresponding to 4400 meters altitude. Across substudy 1 and 2, the investigators hypothesize that altitude-like cognition training has a beneficial effect on cognition after three-weeks treatment completion measured with a global cognition composite score (primary outcome measure). Further, the investigators hypothesize that hypoxia and cognition training will yield improved executive functioning after treatment completion and changes in brain activity during working memory in the dorsal prefrontal cortex 4 weeks after treatment completion (secondary outcome measures). In the patient study, the investigators further hypothesize that the intervention will have beneficial effects on daily-life cognition measured in virtual reality (VR) 4 weeks after treatment completion (secondary outcome measure in substudy 2). For exploratory purposes, the study will examine effects on additional measures of cognition, functioning and self-ratings scales (tertiary outcomes). The investigators will compare the combination of altitude-like hypoxia (12%) and cognitive training with (1) hypoxia with no training, (2) cognitive training under normal oxygen levels (normoxia; 20%), and (3) normoxia with no training in healthy individuals (substudy 1). For patients with mood disorders (substudy 2) the effects of altitude-like hypoxia (12%) and cognitive training are compared to treatment as usual (TAU).
The investigators want to investigate the effect of rTMS on working memory measured by the N-back task. This is a single case experimental design, ABAB.
The objective of this randomised controlled feasibility trial is to evaluate the feasibility of the Smart Taiko Drum-playing intervention embedding the cognitive-motor dual-task training concept for older adults with cognitive frailty, and identify the preliminary efficacy of the intervention on cognitive and physical functions and frailty status.
Over 50% of the Veterans enrolled for VA health care are over the age of 65. Dementia prevalence increases with age, and with the increase in the population of people ages 65 and older, the total number of people with dementia is also increasing. Older Veterans often have comorbid PTSD, major depression and traumatic brain injury so that they are at 2 to 5 times the risk for cognitive impairment and dementia compared to the general population. There is evidence that exercise interventions in sedentary older adults could improve both physical and cognitive function. However, there have been very few studies on the effects of exercise on cognition in older Veterans and do not reflect the broader ethnic and health-status diversity of Veterans. Thus, improved knowledge of the role of exercise on cognition as well as the predictive power of biomarkers could have a major beneficial impact on Veterans' functional independence and quality of life. The investigators hypothesize that participation in the VA Gerofit exercise program will improve cognitive function in older Veterans and that blood and muscle biomarkers will predict these improvements.
