Active clinical trials for "Cognitive Dysfunction"

Heart disease and conditions related to the blood vessels are responsible for a large proportion (over a quarter) of the deaths in people with chronic obstructive pulmonary disease (COPD). The changes can also affect the smaller smaller blood vessels within the body, in particular the brain and the kidneys. This might be related to how the heart pumps and if it is under any pressure. Investigations performed at the University in healthy older volunteers demonstrated how the blood flows in the brain and heart during exercise. Exercise gently puts the whole body under some pressure and therefore exposes any weaker areas. In this study the investigators are hoping to find out what happens to the blood flow in the brain and in the heart in patients who have COPD when they exercise and in the resting state. This will be compared to people of a similar age with a similar smoking history but without COPD. This will be examined using state of the art magnetic resonance imaging (MRI) and will allow us to assess whether changes in structure and function are related to this altered blood flow. Our hypothesis is that COPD will cause a larger change in blood flow during exercise compared to the healthy volunteers and that reduced cardiorespiratory fitness will be associated with increased age related structural within the brain.

Aim of this trial is to define if Post-Operative Cognitive Dysfunction and Delirium, detected analyzing changes between pre-operative and post-operative Neurocognitive Test, relate to concentration of effector's site concentration of propofol and remifentanil TCI and to the common intraoperative neuromonitoring values.

Using the therapy of early intervention with Qianyang Yuyin Granules to improve cognitive impairment caused by hypertension.

Most older people want to stay at home as long as possible. Effective self-management for people losing autonomy depends on reliable monitoring of their mobility, health and safety and active implication in decision-making. New technologies have the potential to provide information about changing patterns that reflect changing care needs. This information could help older adults, caregivers and health professionals to participate in decision-making about housing options when a change in living environment needs to be considered.

Postoperative cognitive dysfunction (POCD) is a severe complication after surgery. Currently, a complicated battery of neuropsychological tests both before and after surgery with other characteristics-matched population as control are needed for the diagnosis of POCD. This diagnosis is also delayed, which could not be used to screen for high risk patients who may need intervention beforehand. The current trial targeted a surgical population of elderly patients undergoing cardiac surgery under cardiopulmonary bypass (CPB), which is a population of the highest incidence of POCD, to screen for possible predictive or diagnostic biomarkers in the serum for POCD. Myeloid differentiation factor 2 (MD2), also known as lymphocyte antigen 96, is a protein involved in biding lipopolysaccharide with Toll like receptor-4 (TLR4). Recently the investigators have found that increased MD2 expression in the hippocampus of the mice after surgery stimuli. On the other hand, the investigators have reported that cystatin C (CysC) as an endogenous neuroprotective factor for stroke. It may also be involved in endogenous neural protection against POCD. This trial is to investigate whether serum MD2, CysC can be used for prediction and diagnosis of POCD in surgical population. Serum based DNA methylation biomarkers will also be tested for prediction or diagnosis of POCD development. Also in our orevious research, SNPs cites at rs6739405、rs12467815、rs12472215、rs11126727、rs11126731、rs993607 were revealed as possible susceptibility variations for POCD (diagnosed with MMSE only, NCT02084030) in patients undergoing CPB. This study will also test the SNP variations in study populations to varify if one or conbination of morethan one of these varuations can be a risk factor for POCD when diagonosed with NPT.

The overarching goal of the proposed study, named SYNERGY, is to explore relationships among balance performance, cognitive function, affective dysregulation, as they relate to the community re-integration in Veterans with TBI. The SYNERGY study findings can aid in the development of a better outcome models for the clinicians in facilitating effective community re-integration in Veterans with TBI

There is no study of the association between ScO2 and POCD in non-cardiac, thoracic or vascular surgery. The few studies found in cardiac, thoracic and vascular surgery show an incidence up to 50% with a variation of the ScO2 threshold which varies between 15 and 25% according to the studies. Age is the main risk of OCDD. The management of this pathology should be early to avoid loss of autonomy of the patient. Finding a relationship, if it exists, would therefore significantly improve the mortality and morbidity of the said patient.

The Gerontology Research Programme (GRP) in the National University Singapore's Department of Psychological Medicine, was formed to coordinate and facilitate the conduct of multi-disciplinary research on in a wide range of research on ageing and health. The establishment of the Singapore Longitudinal Aging Cohort will provide a large community-based cohort of elderly subjects for observational studies with useful clinical applications. Research synergy is achieved in terms of pooling multi-disciplinary expertise, and combining genetic, biological, environmental, behavioural, social, clinical, and health services approaches to gerontological research.

The current central dogma of long-term cognitive impairment after intensive care admission suggests an underlying neuroinflammatory dysregulation affecting neuronal function. This pathological process has not been fully elucidated and there has been little research into its genetic associations. Alzheimer's disease (AD) causes cognitive impairment through a process of abnormal beta amyloid deposition and neuronal death through localised activation of the innate immune system. It is the most prevalent disease affecting cognition. The Apolipoprotein E (APOE) gene is implicated in the progression of late-onset Alzheimer's disease and is a recognised neuroinflammatory modulator. It is possible that young individuals exposed to high levels of inflammation may experience an acceleration of this process. This study sets out to look for an association between APOE-∈4 possession and poor cognitive outcome after a major burn injury and intensive care admission.

This study aims to evaluate the prevalence, biological mechanism and survivorship impact of cognitive toxicity among adolescent and young adult (AYA) patients diagnosed with curable cancers. The hypothesis is that cognitive impairment is clinically significant among AYA cancer patients treated with chemotherapy and that there will be detectable structural and functional changes in the brain for this patient group.
