BRINK (BRain In Kidney Disease) Memory Study 2.0

Chronic Kidney DiseasesDementia11 more

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.

Effects of SUDOKU Mind Activation & Revitalizing Training on Cognitive Function in People With Mild...

Mild Cognitive Impairment

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.

Cognitive Impairment in COPD Patients

COPD

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.

Multiple Nutritional Deficiencies Causing Dementia of the Alzheimer Type

Mild Cognitive ImpairmentAlzheimers Disease

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.

Cognitive Function in Elderly Marathon Runners

Cognitive Decline

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 Difference in Postoperative Cognitive Dysfunction and Myocardial Ischemia Between Propofol and...

Cognitive DysfunctionCardiac Morbidity

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.

Cerebral and Cardiac Blood Flow During Exercise in Patients With COPD

COPDCognitive Impairment

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.
