Filter by:The aim of the current study is to investigate whether daily intake of Nordic berries for 12 weeks can improve cognitive abilities of adults with mild cognitive impairment, and whether the effect can be linked to changes in metabolic parameters.
Evaluation of central nervous system penetration of orally administered Rapamune (RAPA) in older adults with Mild Cognitive Impairment (MCI) or early Alzheimer's disease (AD) and investigate associated safety, tolerability, target engagement, cognition, and functional status as initial proof-of-concept study
A randomized, double-blind, placebo-controlled, two arm cross-over study to determine whether a specific combination of Andrographis paniculata and Withania somnifera can be regarded as a safe and effective treatment for cognitive deficits.
The aim of the current research is to evaluate the efficacy of a combination of Mindfulness-Based Stress Reduction (MBSR) and transcranial direct current stimulation (tDCS) to improve cognitive function in individuals with anxiety, depression and/or cognitive complaints.
The aim of the project is to examine whether children's sleep and cognition are affected by exposure to CO2 and other bio effluents during sleep. The participants of the study are 36 children recruited from local schools in Aarhus, Denmark. The study takes place in the climate chambers at the Department of Public Health, Aarhus University. These chambers allow for experimental testing on humans with advanced exposure generation while avoiding contamination from other sources and controlling temperature, humidity, noise, odor, and light. The children will be sleeping in the chambers under three different conditions: - One night of good ventilation with a CO2 level of maximum 800 ppm - One night of good ventilation with high levels of CO2 (3,000 ppm) - One night of poor ventilation with high concentrations of CO2 (3000 ppm) and other bio effluents. The study is a within-group design, and groups of six children will be sleeping in the chambers for three nights (separated by seven days). The different groups of children are exposed to the conditions in a randomized order. The study is double-blinded (of security reasons the persons responsible for CO2 concentrations in the chambers are not blinded). The study takes place on schools nights. The children arrive at 6 pm and leave for school the morning after. In the evening the children are tested for approximately 30-40 minutes to measure their cognitive performance using CANTAB (Cambridge Neuropsychological Test Automated Battery) on iPads. After completing the test, dinner is served and the children have some spare time before going to bed. During night, the quality of sleep (awake time and different sleep stages) will be monitored using Fitbit devices. Sleep quality will also be evaluated using a short sleep questionnaire. The next morning the cognitive performance of the children will be tested again using CANTAB before the children leave for school. Our primary hypothesis is that children will perform worse on the cognitive test when exposed to high levels of CO2 and other bio effluents than compared to low levels of CO2 and bio effluents in a well-ventilated room. In addition to that our secondary hypotheses are: - Children will perform worse on the cognitive test when exposed to high levels of CO2 and other bio effluents than compared to CO2 alone. - Children will sleep less well in an environment with poor ventilation and high levels of CO2 and other bio effluents compared to sleeping in a well-ventilated room with low levels of CO2. - Children will sleep less well in an environment with poor ventilation and high levels of CO2 and other bio effluents compared to sleeping in a room with high levels of CO2 alone. - Children will sleep less well and perform worse on the cognitive test when exposed to high levels of CO2 compared to low levels of CO2.
Alzheimer's disease is a debilitating condition for patients and their caregivers marked by hallmark cognitive symptoms (e.g., memory loss) as well as an impact on quality of life. Researchers and clinicians are learning that a specific type of memory, called prospective memory, may be particularly affected in mild Alzheimer's disease. Prospective memory is memory for future intentions, goals, and chores, and the loss of the neurocognitive processes supporting prospective memory may reduce independent functioning (e.g., medication adherence). The current study investigates a technology-based intervention to assist participants with their daily prospective memory tasks. Participants with mild cognitive impairment and mild Alzheimer's disease will be trained to use a smartphone for four weeks. Smartphone acceptability, usability, and overall user experience will be measured. Furthermore, participants will be tested on completion of daily prospective memory tasks. In one group, participants will train to use the smartphone personal assistant reminder system, which reminds participants of their goals, tasks, and chores at the appropriate time or location. In a comparison group, participants will also carry a smartphone but will train to use a memory strategy in which they verbalize external cues to remind them to perform their goals, tasks, and chores. The goal of this research is to inform whether smartphone technology or a memory strategy can be used to reduce memory burden and improve daily, independent functioning in participants with mild Alzheimer's disease.
This observational cohort study in healthy volunteers establishes normative data for the German version of the Montreal Cognitive Assessment (MoCA) and investigates the possible impacts of demographics on the MoCA total score.
An observational study will be conducted in the ICU (Intensive care unit) including patients with heart surgery (< 5 days) and prolonged ICU stay (> 5 days). Patients will receive 5 min Virtual reality stimulation per day. A modified version of the Oculus Rift VR glasses (Facebook inc., USA) with stereoscopic vision and stereo sound will be used to present the virtual world to patients. An integrated eye tracker will measure oculomotor responses that will be synchronized with the physiological data recording. All participants will undergo neuropsychological testing after ICU stay, and after a three-months follow-up. Quality of life prior to the ICU stay will be enquired from relatives. Main outcome variable is the explorative behaviour (attention). Secondary outcomes are the quality of life and cognitive functioning.
