Active clinical trials for "Cognitive Dysfunction"

End stage renal disease (ESRD) is the last stage (stage 5) of chronic kidney disease (CKD). Abnormalities of cognitive function and high levels of depression or anxiety incidence are characteristic of hemodialysis patients. In this research project, the investigators subject in ESRD patients starting hemodialysis as the carrier. Based on the longitudinal research design, using multimodal neuroimaging data，combining with the interact relationship between changes of brain morphology, the dysfunction of resting-state and-task state with cognitive impairment and abnormal emotions.Establish brain structure-function change model associated with dialysis progression, Explore imaging markers of central and disease development characteristics in ESRD patients. the investigators attempt to clarify the core mechanism of kidney-brain axis damage, thus provide evidence for early cognitive-behavioral therapy to CKD patient.

In this study, the investigators will be looking at results of tests of memory and thinking and daily activities in a group of people without known chronic kidney disease (CKD) , and a group of CKD patients, and follow the participants for up to four more years, including after the participants start dialysis or receive a transplant. The investigators are doing this study to compare how often memory loss, confusion and difficulty with daily activities occur in those without and those with CKD. Additionally, the investigators are doing this study to identify risk factors for memory and thinking problems in CKD patients. The information received through the NDI will be utilized to help track our study population and help provide useful information regarding cause of death of those in our study.

This study aims to implement a SUDOKU Mind Activation and Revitalization Training (SMART) Program to promote cognitive health among patients with mild cognitive impairment (MCI), and the use of active mind strategy in preventing dementia among the older adults. The SMART Program consists of two components including, a community empowerment-educational campaign on active mind strategies for older adults, and a 24-week SUDOKU Training Programme for people with MCI.

Prior researches suggest the presence of impaired lung function may be linked to cognitive impairment (CI). A recent study shows that lung disease, and specifically Chronic obstructive pulmonary disease (COPD) are associated to a greater risk of CI in a population of 14,184 individuals followed for over 23 years. Moreover, the study shows that low forced expiratory volume in 1 second (FEV1) is associated to an increased risk of dementia and MCI, indipendently of smoking habit.

The aim of the study is to evaluate the differences in cognitive performance and quality of life, after a cycle of treatment with the relaxometer, between a group of patients affected by fibromyalgia and a control group.

The purpose of the study is to compare the concentrations of Vitamin B1 (thiamine), Vitamin B6 (pyridoxal-5-phosphate), folate, Vitamin B12 (cobalamin), Vitamin C (ascorbic acid), Vitamin A (retinol), Vitamin E (alfa-tocopherol), homocystein, uric acid, F2 8-α-isoprostane, 8-deoxyguanosine, retinoids, tau-protein and β-amyloid in spinal fluid, metabolomics, proteomics, m-RNA for DNA repair enzymes and DNA in patients who suffer from mild cognitive impairment (MCI) or mild dementia of Alzheimers type, with healthy controls. A second aim is to explore the association between vitamin and nutrient reductions, if any, and cognitive function as well as vascular score and possible changes in the MRI.

The purpose of this study is to begin the process of validating fMRI (functional magnetic resonance imaging) as a biomarker for use in clinical trials and longitudinal studies of clinical progression in mild cognitive impairment (MCI) and Alzheimer's disease (AD).

There is substantial research on the effects of physical exercise on cognitive functions. However, less attention has been paid on the requirements of training intensity and length to enhance cognitive abilities in the elderly. To the investigators knowledge no studies have evaluated the effects of extensive endurance exercise training on cognitive functions by studying elderly marathon runners and bicyclists. On the basis of the scientific literature published so far it is not known whether the beneficial impact of endurance exercise training depends on the intensity of training. The investigators therefore designed a cohort study with adequate power in order to evaluate the effects of intensive endurance exercise training on cognition. This trial, an Austrian prospective cohort study in cognitive function of elderly marathon-runners (APSOEM) is being conducted and will compare neuropsychological performance outcomes of elderly marathon runners or bicyclists with controls matched concerning age, education years, occupation, and verbal intelligence.

The progressive aging of the general population cause increase in number of extensive and long surgeries in older patients. Age is a risk factor for perioperative myocardial ischemia and Postoperative Cognitive Dysfunction (POCD) The suggested study will deal with the above-mentioned complication in patients older then 65 years undergoing major non-cardiac surgeries. It has been shown that Isoflurane and sevoflurane may have a cardio-protective effect after cardiac surgery involving cardio-pulmonary bypass, and it was recommended that isoflurane should be used in these cases. A question was raised but haven't been answered yet, whether this cardio-protective effect exists also in non-cardiac major surgery. The aim of this study is to evaluate whether there is a difference in the occurrence of postoperative cognitive dysfunction and perioperative myocardial ischemia between total intravenous anesthesia using propofol and isoflurane based anesthesia.

The purpose of this study is to investigate whether markers of brain structure and function from MRI are associated with different levels of spatial orientation and gait parameters in people with mild cognitive impairment or dementia due to Alzheimer's disease when walking through a real world environment.
