Filter by:The aim of the present study is to evaluate an innovative virtual reality-based balance training intervention for improving clinically relevant motor performances (balance and gait) in people with mild cognitive impairment. The investigators hypothesize that the virtual reality-based balance training intervention will improve balance and gait performances in people with mild cognitive impairment compared to a control group receiving usual care only.
The purpose of this study is to investigate the effectiveness of a preventative low-dose of Haloperidol to prevent delirium in patients undergoing a esophagectomy, pneumonectomy or thoracotomy. Delirium is state of severe confusion and some symptoms include: - Cannot think clearly - Have trouble paying attention - Have a hard time understanding what is going on around them - May see or hear things that are not there. These things seem very real to them.
19% of Wales' population speaks Welsh. Under the Welsh Language Act 1993, every public body providing services to the public in Wales has to prepare a scheme setting out how it will provide those services in Welsh. Diagnosing dementia requires a comprehensive assessment, an essential component of which is a cognitive assessment tool, which takes the form of a questionnaire. In clinical practice, this is currently only available through the medium of English. The investigators objective is to measure the difference between Cognitive Assessment scores (using the Montreal cognitive assessment (MoCA)), when done in English and Welsh, in those who are cognitively impaired and whose first language is Welsh. The investigators predict that there will be a significant difference in scores in favour of the Welsh-medium tests, thus proving that the current mode of administering the test is prejudiced against patients whose first language is Welsh. If the investigators predictions are correct, then the investigators would seek to introduce a validated Welsh-language cognitive assessment tool to the domain of the Welsh NHS.
This research aim to explore relationships between the presence of amyloid burden and cognitive performance, and its modulation by educational level. For this purpose we will combine Positron emission tomography (PET) imaging and neuropsychological assessment acquired on 3 groups of subjects, from two population-based cohorts "3C" and "AMIMage" The first group includes cognitively intact participants who will serve as controls, the second group, subjects with mild cognitive impairments without memory complaint and the third, subjects with both mild cognitive impairments and memory complaint.
The purpose of the study is to determine the effect of an web-based intensive cognitive rehabilitation program in neuropsychological performance of a population of patients with multiple sclerosis or clinical isolated syndrome.
Mild cognitive impairment (MCI) is a precursor of dementia. Apathy, a profound loss of motivation, is a common behavioral problem in MCI. Presence of apathy may increase the chance of MCI patients converting to Alzheimer's Dementia. Repetitive Transcranial Magnetic Stimulation (rTMS), a non-invasive tool, has been recently approved for treatment of refractory depression. Since dysfunction in the frontal lobe of the brain is seen in patients with apathy, rTMS to the frontal lobe might be helpful in treating the same. Study hypotheses include that rTMS to the dorsolateral prefrontal cortex (DLPFC) will improve apathy and executive function better than sham treatment in those with MCI
STUDY HYPOTHESIS In cardiac surgery the volume of perioperative cerebral infarctions can be reduced by increasing mean arterial pressure (MAP) during the cardiopulmonary bypass procedure. BRIEF STUDY SUMMARY Heart surgery using cardiopulmonary bypass (CPB) can be complicated by injury to the brain. Previous studies using brain scans have reported small stroke-like lesions in up to 51% of patients after cardiac surgery. However, only 1-6 % of patients have permanent symptoms of severe brain damage. The majority of brain lesions seem to be caused by particulate matter (emboli) that wedge in blood vessels of the brain thereby compromising flow. In addition, insufficient blood flow to areas of the brain supplied by narrowed, calcified vessels may contribute. MAP during CPB usually stabilizes below the lower limit of cerebral autoregulation, which is accepted since sufficient total blood flow is guaranteed during CPB. The aim of the PPCI trial is to investigate if increased MAP during CPB can prevent or reduce the extent of brain injury after cardiac surgery. A beneficial effect could result from reduced embolic injury through increased blood flow in collateral vessels and/or by increased blood flow in calcified arteries. 180 patients scheduled for cardiac surgery will be randomly allocated to increased MAP (70-80 mm Hg) or 'usual practice' (typically 45-50 mm Hg) during CPB, whereas CPB blood flow is intended equal and fixed in the two groups. Patients are examined before and 3-6 days after surgery with magnetic resonance imaging (MRI) brain scans, mental tests and by blood borne markers of brain injury. If higher MAP during CPB is beneficial, a change of practice can easily be implemented in the clinical routine.
Methylphenidate (MPH) has long been used to improve attention and cognitive difficulties associated with ADHD, including in children with ADHD and epilepsy (Torres et al., 2008). Methylphenidate (MPH) is also helpful in treating attention and other cognitive difficulties in a variety of other neurological and medical conditions (Kajs-Wyllie, 2002; Prommer, 2012). We seek to evaluate the potential efficacy and safety of this medication in treating attention deficits, as well as other cognitive difficulties, experienced by adult patients with epilepsy. To our knowledge, there are currently very few studies which explicitly examine the impact of MPH on measureable attention deficits and other cognitive deficits in adult patients with epilepsy. We hope to quantify what impact, if any, methylphenidate has on attention, in addition to other specific measureable cognitive functions, in patients with cognitive complaints and epilepsy, and contribute to a growing body of evidence which supports the safety of methylphenidate's use for attention deficits in patients with epilepsy. As other effective treatments for attention and other cognitive difficulties in patients with epilepsy are not currently available, MPH could represent an important option in the treatment of such patients.
Cognitive and memory problems characterize Alzheimer's disease (AD). Along with these disorders, psychological and behavioral symptoms (also known as neuropsychiatric symptoms) , as well as pathophysiological processes are frequently found and involved significantly in maintaining autonomy, prognosis and treatment of the disease. Apathy or disorder motivation is the most common disorder behavior and early stages of cognitive impairment. Apathy is particularly associated with cognitive difficulties such as attention deficit disorder - concentration. In terms of prevention as term care , there is now a broad consensus that interventions on cognition and behavior must not be limited to pharmacological treatment but should also promote non-drug approaches. Interest in video games (serious games and serious games) as intervention support rehabilitation is growing. Similarly, the virtual reality (VR) and the new information technologies and communications offer significant opportunities in terms of rehabilitation and therapeutic assistance. This protocol is part of a European project to propose techniques for improving the treatment of people at risk of social exclusion ( VERVE project ) aims . A first experiment conducted in 2013 showed the acceptability of Virtual Reality (VR) in healthy elderly subjects. In a second step , it is important to validate the feasibility of using the RV or in frail subjects with mild cognitive impairment or Alzheimer's disease in mild to moderate in a clinical environment. This is a biomedical , randomized given to a group of patients with mild cognitive impairment or Alzheimer's disease & diseases associated with mild to moderate.
Postoperative cognitive dysfunction (POCD) may lead to serious consequences. But the underlying mechanisms are still unclear. Blood Oxygen Level Dependent (BOLD) fMRI and biochemical indicators will be used to explore the underlying mechanisms and represent a promising precursory target for diagnosis and treatment of POCD.
