Active clinical trials for "Cognitive Dysfunction"

The investigators are conducting a pilot study to compare cognitive outcomes among Veterans with severe aortic valve stenosis who are scheduled to undergo either aortic valve replacement.

Despite the availability of numerous cognitive assessment tools, cognitive impairment related to dementia is frequently under-diagnosed in primary care settings. The investigators have developed a 5-minute cognitive screen (5-Cog) coupled with a decision tree to overcome the technical, cultural and logistic barriers of current cognitive screens to improve dementia care in primary care patients with cognitive concerns.

The purpose of this study is to use transcanial doppler (TCD) ultrasound to look for possible risk factors for ischemic brain injury. We will perform contrast TCD with agitated saline contrast to identify and contrast right-to-left shunt (RLS) and breath holding to assess cerebrovascular reactivity (CVR) in the elderly.

By doing this study, researchers hope to learn if older adults with and without cognitive impairment can adhere to a Mediterranean diet.

This study is an open trial investigating the long-term use of an online brain training programme for adults over 50. It will determine whether there is sustained benefit to cognition, and whether this group can be engaged in this form of intervention over a period of 12 months.

This is a 3 month cluster randomized controlled trial using a square-stepping exercise program (a.k.a. mind-motor exercise) in retirement and long-term care residences to improve global cognitive functioning in older adults with and without cognitive impairments. The investigators intend this project to be pragmatic and therefore will include residents with dementia and walking aids if the participants wish to participate. The primary outcome is global cognitive functioning, secondary outcomes include: single and dual task gait (only completed with those without dementia), oculomotor functioning, and functional fitness. The investigators hypothesize that there will be improvements in primary and secondary outcomes in the intervention group.

The whole body vibration exercise group will have significantly more improvement in mobility, muscle strength, balance, balance confidence, and cognitive function with a lower fall rate than the control group.

The main purpose of this study is to better evaluate prematurely born children cognitive development at school age, with regards to birth conditions but also to social situation, intra family relationships, and modalities of care. The study will be divided into 3 parts: Children born prematurely in our level III referral Center will undergo psychometric evaluation at 8 to 11 years of age by routine cognitive test. The relationships between cognitive scores and neonatal characteristics will be determined and compared to the results of schoolmates born at term. The quality of parent and child relationship will be evaluated by a standardized questionnaire allowing the evaluation of persistent stress trauma related to premature birth. An anthropologic study of the utilization of care resources will also be performed within the follow-up network taking care of these children.

This is a cross-sectional and longitudinal study to evaluate the clinical utility of [18F]THK-5351 positron emission computed tomography in cognitively healthy volunteers, mild cognitive impairment (MCI), Alzheimer's disease (AD) and other neurodegenerative patients.

The aim of the study is to show that regular playing with the logic games developed in the framework of the M3W (Mental Wellness Toolset) project (https://m3w-project.eu/) can prevent mild cognitive impairment (MCI) and dementia. The secondary aim of the study is to find correlations between the results of the games and the standard assessments for dementia and MCI screening such as the Rey Verbal Learning Test.
