Active clinical trials for "Cognitive Dysfunction"

The goal of this interventional study is to implement and evaluate the adhesion to two types of intervention strategies for assessing cognitive function, at Family Health Units (FHU), providing primary care clinicians (PCC) with support to the decision process, regarding the referral of patients suspected of having mild cognitive impairment (MCI) or early dementia to the specialized consultation of Neurology at the public hospital services. The defined intervention strategies are the paper version of the cognitive tests MMSE and MoCA -group MMSE/MoCA-and the digital web-based platform Brain on Track - group Brain on Track/MMSE/MoCA -, which will be compared with the regular clinical practice as the Control Group. The main question it aims to answer is: • the impact on the referral process of the implemented cognitive assessment strategies in the two intervention study groups compared with the Control Group. Trained health professionals, at FHU, will administer the cognitive tests mentioned above to the eligible patients suspected of having MCI or early dementia, in the intervention groups and, according to the respective results and other criteria used during the consultation, PCC will decide about the need of referral to the Neurology consultation. In the Control Group, health professionals will provide the regular clinical assistance practised in the respective FHU. If the referral occurs, the Neurology specialist will perform a complete clinical neuropsychological assessment of the referred patients and will validate the suspected diagnosis made at FHU. Eligible patients with suspected MCI or early dementia will perform the cognitive tests according to the intervention study group, at the FHU or remotely. In the Control Group, eligible patients will be assisted through the daily clinical practice in the respective FHU. The research team will compare the intervention study groups, MMSE/MoCA and Brain on Track/MMSE/MoCA, with the Control Group, to see if there is an improvement on the referral process in the intervention groups, compared with the Control Group .

Background: Exposure to nature has a positive impact on a multitude of health-related outcomes such as stress, attention, recovery after surgery, and overall well-being. There is growing interest in determining the impact of vicarious nature experiences delivered through multimedia platforms on the well-being of persons at high risk for poor psychosocial outcomes, as is the case in older adults diagnosed with mild cognitive impairment (MCI) or mild dementia. Objectives/Purpose: The primary purpose of this study is to assess the feasibility of providing an immersive nature-based multimedia experience to older adults with MCI or mild dementia. A secondary purpose is to identify the potential health benefits of this intervention. Methodology: A convenience sample of 40 older adults (65+ years old) with and without mild cognitive complaints will be recruited from a Los Angeles senior service partner. Participation will include three visits. The first visit will include the consent process, cognitive testing, and questionnaire completion. The second and third visits will consist of a video session followed immediately by a group discussion regarding the content in the videos. The two video sessions will be administered in a randomized and counterbalanced manner one week apart. One video involves a 15-minute immersive nature-based experience and the other includes a 15-minute clip that presents emotionally "neutral" educational content. Both sessions will be immediately followed by a group discussion of the content in the videos and how it relates to past experiences. Outcomes and Analysis: Process evaluation data associated with recruitment, screening eligibility, involvement of personnel, assessment administration, and retention will be collected to determine overall study feasibility. Additionally, selected assessments will be administered at each multimedia experience during key time points to examine potential short-term health benefits.

This study evaluate the cognitive functions of patient after hip or kneel replacement.Half of the patient will receive transcutaneous vagus nerve electrical stimulation during the surgery while the other half will get placebo therapy

The purpose of this study is to evaluate the impact of 12 weeks of exercise on cognition in patients with end stage renal disease.

Noninvasive brain stimulations (NIBS) will be used in MS patients with cognitive impairments to enhance their cognitive aptitudes.

We aim to use a multimodal approach comprising conventional neuropsychological cognitive tests, fluid and imaging biomarker data, to explore their association with the FLAME unsupervised cognitive computerized assessment. We believe that this would provide critical information to move forward the current research framework in the field. Participants will be selected from BBRC-sponsored studies, such as the ALFA project (STUDY 45-65 FPM/2012), the ALFA+ cohort study (ALFA - FPM - 0311), the Beta-AARC study (β-AARC_BBRC2020) or the BarcelonaBeta Dementia Prevention Research Clinic study (BBRC-DemPrev-2018)

The investigators propose to perform serial detailed cognitive, motor, behavioral, and blood collection follow-up using longitudinal structured telephone interviews of an anticipated 350 ICH survivors enrolled in Minimally Invasive Surgery Plus Alteplase for Intracerebral Hemorrhage Evacuation (MISTIE) III and ENRICH trials to identify specific cognitive and motor impairment and to perform RNA sequencing to evaluate for evidence of chronic inflammation. The investigators' expected sample size in 2022 accounts for mortality attrition of 10%/year.

Alzheimer's disease (AD) is characterised by a progressive loss of memory and cognitive function. In the early stages of AD, there is a progressive accumulation of molecules: β-amyloid peptides (Aβ) in the brain. There is a link between the accumulation of Aβ peptides and the deterioration of sleep, but current knowledge does not confirmed this link. The objective of this study is to define whether there is a link between cognitive decline and sleep disorders. If a correlation is found, this could allow earlier treatment of sleep disorders in the longer term in order to slow the development of AD.

Age-related hearing loss (ARHL), like neurodegenerative diseases, appears insidiously with age. As major public health issues, they are nonetheless under-diagnosed because the presence of one can hinder the objectification of the other. The CogAudio project aims to detect early and in an ambulatory mode in a memory centre a speech perception disorder in noise thanks to the VRB test in patients weakened by cognitive disorders.

Population aging makes it necessary to identify factors related to unhealthy aging. The purpose of this study is to examine the association between ideal cardiovascular health, diet and other lifestyles and biological risk factors (either clasical or emergent) and the risk of physical and cognitive function impairment and mortality in a cohort of community-living individuals aged 65 years and over.
