Filter by: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.
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.
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.
Regular physical activity improves physical and mental health and reduces the risk of heart disease, stroke, cancer, diabetes, obesity and premature death from any cause. Unfortunately the majority of adults are not active enough to reap these benefits. People who are inactive and at high risk of stroke, heart disease, diabetes and dementia, and who may benefit from increased activity can be identified in primary care by combining standard risk tools. These high risk patients can be offered physical activity programmes that are designed to increase longterm adherence. Aerobic dance is an activity that combines physical, social and cognitive stimulation and allows easily adjusted intensity levels to meet individual needs. Engagement in an activity program also provides opportunities to offer advice on healthy nutrition and associated meal preparation skills. Information technology can be used to increase activity participation. Video materials can be produced to guide activity participation at home, thereby increasing overall activity participation. The investigators propose a feasibility study of a multimodal dance-based physical activity and nutrition intervention aimed at patients at high risk of stroke, heart disease, diabetes and dementia, in primary care settings.
Insulin-like growth factor 1 (IGF)-1 is an important neuromyotrophic hormone. Disregulation of this hormone has been reported to influence the genesis of cognitive impairment and dementia in the elderly patients. We analyzed the possible link between IGF-1 and risk of Sarcopenia and Mortality in a cohort of elder patients with cognitive impairment.
Obsessive compulsive disorder (OCD) is a severe and debilitating anxiety disorder afflicting 2% of the population. Cognitive behavioural therapy (CBT) is considered first line psychological treatment for OCD, but there are a large number of treatment non-responders, and the majority of responders have residual symptoms. Aerobic exercise has shown potential benefit for general mood and anxiety disorders, but has not been widely tested in OCD. This study will examine the additive benefits of a standard 12-week aerobic exercise program to a standard 12-week CBT protocol in the treatment of OCD. The study will test if Exercise+CBT results in significantly better clinical outcomes compared to either treatment alone or no treatment at all. Treatment outcomes will be assessed in relation to symptom and cognitive measures of clinical improvement.
This is a study of the effects of tDCS on smoking, craving for cigarettes, cognition, and psychiatric symptoms in schizophrenic patients who are current smokers or have a history of regular cigarette smoking. It assesses smoking with CO monitoring, nicotine and nicotine levels, and craving with QSU scale and response to craving slides. Cognition is measured by MCCB, symptoms are measured by PANSS and hallucination scale. This is a double-blind sham-controlled study with active tDCS 2ma or 20 minutes over 5 days, and sham tDCS for 40 seconds on each sham occasion.
Some studies reported that selenium status is associated with cognitive function. However only a few reports have investigated whether selenium supplementation can benefit cognitive performance and in most of them selenium supplementation was not exclusive. Also, none of those reports have used foods rich in selenium as a source of supplementation. Thus, the aim of our study was to investigate whether the consumption of Brazil nuts improves cognitive function. We hypothesized that the daily consumption of Brazil nuts would have benefits on selenium status, increase antioxidant enzyme activity and improve cognitive function in older adults with MCI.
The purposes of this study are: 1. To investigate whether a 3-month exercise training program would improve cognitive function, motor performance, integrity of brain fiber tracts and cerebral blood flow; 2. To investigate the possible neuro-anatomical and neurophysiological mechanisms of exercise training on cognitive function, motor performance, integrity of brain fiber tract and cerebral blood flow in patients with mild cognitive impairment and in those with early Alzheimer's disease; 3. To investigate the influence of different apolipoprotein E (APOE) genotypes on the above-mentioned exercise effects. The results of this study will provide medical evidence for the effects of exercise training on mild cognitive impairment and on early Alzheimer's disease; and will provide understanding of the mechanisms mediating these effects. More importantly, the results serve as the basis for future larger-scale exercise clinical trials for these two patient populations.
The objective of this protocol is to develop items for a patient-reported outcome (PRO) measure to assess the patient's perspective and subjective experience of cognitive impairment associated with schizophrenia (CIAS).
