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.
Patients with failed kidneys need Renal Replacement Therapy (RRT) to remove fluid and toxins from the body. The 3 types of RRT are kidney transplant or removal of waste by dialysis, either via the blood (haemodialysis) or via the stomach area (peritoneal dialysis). 27,000 patients currently receive dialysis in the UK and some endure reduced quality-of-life, depression, and thinking and memory difficulties. Some of these symptoms reflect undiagnosed dementia. Indeed up to 7/10 dialysis patients suffer moderate to severe brain impairment or dementia - much more frequently than in the general population. This study will assess brain function just before starting dialysis/transplant and at 3 and 12 months afterwards with face to face assessments and with brain scans in some patients. Changes in brain function will be compared between people treated with the different forms of dialysis and transplant. The Investigators hope to evaluate whether these tests are acceptable to patients, whether affected sub-groups with cognitive impairment can be identified early, and if certain dialysis methods are better for patients with cognitive impairment/dementia, so that a larger study to try to improve brain function after RRT can be developed.
Many patients with primary brain tumors experience cognitive deficits and cognitive rehabilitation programs aim to alleviate these deficits.The cognitive rehabilitation program developed by the investigators proved effective in a large randomized controlled trial (RCT). To increase its accessibility, it was converted into the iPad-based cognitive rehabilitation program ReMind, which incorporates psychoeducation, strategy training and retraining. A pilot study and a randomized controlled trial are conducted, to evaluate the feasibility of the use of the program and the efficacy of the program in brain tumor patients after resective surgery.
The project presented here respond to this emerging need by implementing a Reminiscence Therapy program dedicated to elderly people in an institutional context. This will be a multicenter, randomized controlled study in which the participants' allocation will be made without their knowledge. Before the randomization process, the screening evaluation will be done, which will allow to verify the presence of the inclusion and exclusion criteria. The target population will be people age 65 or above years who present cognitive decline. After the randomization process, participants will be allocated randomly in the experimental group where the reminiscence program (composed by a main strand and maintenance strand) or in the usual institutional care group. The evaluation of the participants will be carried out individually and will take place in four different moments.This study will be conducted in RSE in the central region of Portugal.
The present observational study is aimed at reporting the short-, mid- and long-term outcomes of patients with Disorder of Consciousness (DOC), in Vegetative State (VS) or Minimally Conscious State (MCS), due to a severe Acquired Brain Injury (sABI), after repeated treatments with anodal Transcranial Direct Current Stimulation (tDCS) on Left Dorsolateral Prefrontal Cortex (L-DLPFC), to stimulate recovery of consciousness. The results obtained will also be compared with those of a historical control cohort, before the introduction of tDCS, matched for demographic and clinical characteristics.
This observational cohort study is designed to validate the CogCheck application as a risk prediction tool for postoperative delirium in patients undergoing cardiac surgery.
The current study aims to investigate the effects of two GI diets (low vs. high GI) in a sample (25 participants) that has diet controlled type 2 diabetes. This sample has been chosen as those with diabetes have been shown to suffer with poor glucose tolerance, along with the associated deficits such as compromised cognitive function. Therefore, it is expected that differences produced by the two diets on blood glucose concentrations and cognitive performance will be greater than those previously seen. If this is the case after analyzing the results, it will provide a potential strategy (diet) for improving glucose tolerance and cognitive performance in a vulnerable section of the population.
Sectorisation of the German health care system causes inefficient treatment, especially in elderly with cognitive impairments. At time of transition from hospitals into primary care it lacks, among others, coordination of post-operative care or timely communication between healthcare providers. This results in deterioration of disease and comorbidities, higher rates of re-admission and institutionalizations. Models of collaborative care have shown their efficacy in primary care. Main goal is to test the effectiveness of Dementia Care Management (DCM) for people with cognitive impairment to improve treatment and care across the in-hospital and primary care sector. The study design is a complex, longitudinal, multisite randomized controlled trial. It was designed to treat a hospital-based epidemiological cohort of people above the age of 70 with an adaption of DCM, a treatment proven to be effective in primary care, to the discharge setting. As part of this, specifically trained study staff will develop, implement and monitor a treatment and care plan, based on comprehensive assessments during the hospital stay, recommendations at discharge and unmet needs at home. For the 3 months after discharge study staff will coordinate treatment and care in close cooperation with the discharging hospital, treating physician and other care providers. Expected results from the study should facilitate the implementation of intersectoral care management systematically on a large scale. Thus, the benefits shown in the trial would be available to a larger population. Results will not be limited to PCI, but rather to any people transitioning between the in-hospital and the primary care sector. Thus, the benefits would be available to elderly people in general.
Postoperative Cognitive Dysfunction (POCD) is a state of decline in cognitive ability after surgery and is frequently seen among our elderly population. Many studies have looked into predictive risk factors for POCD while research is underway to search for pre-emptive measures to avoid this unfavourable outcome. Most will be looking at utilizing mobile software applications of cognitive training but in many poorer countries, owning electronic devices may not be an option or may be culturally less acceptable among the older patients. Hence, the investigators intend to investigate if a home-based logbook for cognitive training will reduce the incidence of POCD in a single centre study.
