Filter by:The purpose of this project is to evaluate an exercise and health promotion program for older adults with mild memory loss. The study will investigate the efficacy of a memory-enhanced exercise and health promotion program to determine whether it is more effective than a social walking program in delaying further memory decline, improving mood and physical function, and enhancing quality of life.
The purpose of this study is to find out if insulin, when administered as a "nasal spray" into the nasal passages, improves memory in adults with mild cognitive impairment (MCI) or Alzheimer's disease.
The purpose of this study is to find out if different doses of Investigational Drug are safe, tolerable, and if they have an effect on Mild Cognitive Impairment (MCI).
The primary objective is to compare mild cognitive impairment in the AL-208 group with the placebo group at 14 + - 3 days after CABG surgery
The purpose of this study is to determine the effects and cost-effectiveness of a Diagnostic Observation Center for PsychoGeriatric patients (DOC-PG). Our main hypothesis is that DOC-PG has added value compared with usual care regarding Health Related Quality of Life (HRQoL).
Background: Different anaesthetic agents have been shown to have different protective effects upon heart, brain and renal function under ischaemic conditions (oxygen starvation). Cardiopulmonary bypass takes over the work of the heart and the lungs during heart surgery, but oxygenation of vital organs such as the brain and heart may not be perfect, and can produce brain or heart damage as a consequence. Propofol and desflurane are commonly used anaesthetic agents, and there has been recent research to suggest that anaesthetic agents may provide some protection during periods where inadequate oxygenation occurs, with the potential to reduce the degree of organ damage. Both types of anaesthetics are used for cardiac surgery with anaesthetists choosing between them largely on the basis of personal preference. Aim: To determine whether the use of either propofol or desflurane as the primary anaesthetic agent, can lead to differences in postoperative brain function, total morbidity or cost, following coronary artery surgery with cardiopulmonary bypass. Methods: Patients will be recruited by professional research staff and will be randomised into one of two groups (90 in each group). They will receive a standardized technique for anaesthesia, cardiopulmonary bypass and postoperative ICU treatment. The only difference between the 2 groups will be as to which anaesthetic agent they receive during the surgical period, desflurane or propofol. Measurements will involve i) brain function testing before and 3 months after surgery ( a set of 10 verbal or manual tests), ii) incidence of delirium in the immediate postoperative period (a survey form), iii) incidence of total postoperative morbidity and iv) cost of hospital stay. Data collection will be by anaesthesia and research staff and a neuropsychologist will employed for performing the brain function testing. Anticipated timeline: Initial recruitment completed by 15-18 months following trial commencement. Follow up completed 3 month after the last enrolment. Data validation, statistical analysis and manuscript preparation completed by 24 months.
The primary purpose of this proposal will be to identify potentially modifiable risk factors of long-term cognitive impairment (i.e. development of delirium and exposure to sedative and analgesic medications) in ICU patients. The investigators will quantify the independent contribution of these risk factors to the incidence of long-term cognitive impairment, controlling for other established risk factors including age, pre-existing cognitive impairment, and apolipoprotein E (apoE) genotype. Quantifying the contributions of these modifiable risk factors will pave the way for the development of preventive and/or treatment strategies to reduce the incidence, severity and/or duration of long-term cognitive impairment and improve functional recovery for patients with critical illness.
The investigators hypothesize that continuous active interaction with environments that are demanding to sensory, cognitive, and motor systems, together with imbedded rewards for successful performance, will help improve memory and cognitive functioning in patients suffering from "chemobrain".
The purpose of this study is to determine the neuropsychological and neurophysiological impacts of a computer-based training program designed to improve the cognitive performance of patients with mild cognitive impairment (MCI).
This study aims to determine whether levodopa is effective in boosting learning and memory in healthy subjects and patients with dementia or Mild Cognitive Impairment. We also examine in healthy subjects using functional magnetic resonance imaging which brain regions mediate improved learning after levodopa administration.
