Active clinical trials for "Cognitive Dysfunction"

The proposed study is designed to evaluate the performance of the ALTOIDA™ System as a tool to assist physicians in diagnosing Alzheimer's Disease (AD) in real-world clinical settings. The design of this study is guided by two overriding factors: 1) to optimize the performance of the ALTOIDA™ Neuro Motor Index (NMI) prognosis classifiers, the subjects making up the training sets must be well characterized as to their clinical diagnosis, and 2) all ALTOIDA™ tests must be performed and reproduced in real-world clinical settings. Although there is already a large body of peer-reviewed scientific literature demonstrating that certain digital biomarker patterns are associated with certain neurologic conditions, the utilization of such tools for the evaluation of neurologic disorders is still considered an emerging science and therefore in the investigational stage. Although this protocol will report on brain patterns of certain neurologic conditions such as cognitive impairment and Alzheimer's disease, based on patterns published in peer-reviewed journals, such findings are not considered stand alone or diagnostic per se and should always be considered by the primary physician in conjunction with the patient's clinical condition. These data should only be used as additional information to add to the primary physician's diagnostic impression.

Physical activity exerts a variety of long-term health benefits in older adults.This randomised controlled trial investigates the effect of a 12-week physical exercise program on the change in cerebral metabolism as assessed with Magnetic Resonance Spectroscopic Imaging. Follow-up lasts for 6 months.

The purpose of this study is to clarify the benefits to brain health and thinking processes that result from different forms of exercise. This study will examine the effectiveness of cybercycling (virtual reality enhanced stationary cycling) for persons at risk for and with MCI, and compare this with the individual cognitive, behavioral, and physiological effects of physical and mental exercise alone. The Investigators hypothesis that cognitive benefit will be greatest for combined aerobic and cognitive exercise compared to physical and mental exercise alone.

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.

Background: The postoperative cognitive dysfunction (POCD) is a frequent complication, often underestimated and leads to a negative impact on the quality of life for patients and their families. Objective: Measure the effectiveness of the cognitive training in reducing POCD in patients 55 and 70 years old undergoing elective non cardiac surgery with a degree II-III (medium-high) in "Centro Médico Teknon" Barcelona, during 2017-2018. Methodology: Randomized control clinical trial. The anticipate sample size is approximately 225, 75 in each group. Cognitive training performed at different stages of the perioperative period. Measure the cognitive function through a battery of neuropsychological tests during the preoperative (10 days pre-surgery) and postoperative (at 3 - 30 and 90 days post-surgery). Data analysis: SPSS 22, descriptive and inferential analysis: Chi-square, Student's t-test, ANOVA and Pearson correlation (p<0,05). Limitations: Loss for non-intervention and loss of follow-up. Applicability: Strategy to improve the quality of life patients and reduce socioeconomic costs associated.

This study aims to assess if/how dietary interventions (i.e., the Modified Atkins Diet (MAD) and/or the Mediterranean-Dietary Approaches to Stop Hypertension (DASH) Intervention for Neurodegenerative Delay (MIND)) might prevent, delay onset, alleviate symptoms, or otherwise alter the course of subjective cognitive decline (SCD) likely due to Alzheimer's disease (AD). We hypothesize that participants will tolerate both diets well and that the MAD will result in more favorable changes in cognition and other functioning.

Available evidence suggests that there is no significant difference in the incidence of postoperative cognitive dysfunction POCD when general anaesthesia and regional anaesthesia are compared[13, 14]. To the knowledge of the investigators , no studies are examining the effects of ketamine on cognitive outcomes in the setting of spinal anesthesia. Thus, the purpose of this study was to compare the cognitive status, as assessed by the SPMSQ, of elderly patients undergoing orthopaedic surgery under spinal anaesthesia before and after ketamine administration. The authors hypothesized that patients receiving ketamine would exhibit better cognitive performance.

This one arm clinical study will assess the impact of a goal directed therapy intervention, aiming at optimizing depth of anesthesia and intraoperative blood pressure on the incidence of postoperative cognitive dysfunction and delirium relative to a standardized anesthetic plan. We will enroll 60 patients and will measure the neurocognitive status (MoCA test) of patients before and after surgery (at discharge, within 2 weeks after surgery and 6 months after surgery) to determine the relative impact of anesthetic care on the development of postoperative delirium and cognitive decline. All patients will have a brain scan (fMRI) before and after surgical intervention. Patients will also be asked to participate in an optional blood draw which will take place during their brain imaging visit and post operatively (within 2 days after surgery).

HYPOTHESIS In older adults who receive a direct intervention from the perspective of occupational therapy with a "Training Program in Daily Cognition", there are greater benefits, both in the overall cognitive performance and in the levels of daily cognition, that in the older adults who receive an intervention based on a "Traditional Cognitive Stimulation Program", achieving not only an improvement or maintenance of cognitive functions, but a generalization and transfer of that improvement in their daily lives and occupational performance. OBJECTIVES: To evaluate the effectiveness of a "Training Program in Daily Cognition" in the elderly, to improve the levels of daily cognition and global cognitive performance. SPECIFIC OBJECTIVES: Compare the difference in levels of daily cognition between the participants of the control group who carry out a "Traditional Cognitive Stimulation Program" and the participants of the experimental group who carry out a "Training Program in Daily Cognition". Analyze if there is a difference in the levels of global cognitive performance between the participants of the control group that carry out a "Traditional Cognitive Stimulation Program" and the participants of the experimental group that carry out a "Training Program in Daily Cognition". To study the relationship between standard psychometric tests that measure cognitive performance and the ECB Daily Cognition Battery Recognition Test that measures daily cognition. Analyze if there is a relationship between age and cognitive performance and the daily cognition of the elderly. Describe the relationship between the educational level that the participants possess and the cognitive performance and their daily cognition Evaluate the impact of gender in the elderly with cognitive performance and daily cognition. Check whether or not physical activity influences the cognitive performance and daily cognition of study participants. STUDY DESIGN: Experimental, randomized, stratified, prospective, longitudinal study using a parallel scheme of fixed allocation experimental group and control group. The protocol has been authorized by the Ethics Committee of the Salamanca health area to make the project possible.

This is a safety study of the molecule VU319 to ascertain pharmacokinetic and pharmacodynamic data and test cognitive enhancement in healthy volunteers.
