View clinical trials related to Neurocognitive Decline.
Filter by:The study has a randomized crossover design including qualitative interviews of the participant's test experiences. Healthy participants, ≥60 years are eligible to participate in the study. Cognitive function will be measured by using the International Study Group of Postoperative Cognitive Dysfunction (ISPOCD) test battery and the Mindmore digital test battery. The participants will self-report their likelihood of depression with the geriatric depression scale-15, their user experience of the digital test by a modified version of System Usability scale, and answer questionnaires targeting their experiences of the test sessions. Furthermore, concentration difficulties, according to the Swedish Quality of Recovery-scale will also be measured.
This study will evaluate the effects of switching Atripla to Eviplera on neurocognition measured by neuropsychological testing and functional MRI
Patients having cardiac surgery to correct their heart disease may suffer a decline in mental and neurologic abilities. Passage of small particles of fat, tissue waste and air bubbles to the brain while on the heart-lung machine is thought to be one cause for decline in mental and neurologic abilities (the function of brain) after surgery. The purpose of this study is to determine if replacement of cardiotomy suction (one part of the heart-lung machine) with the cell-saver (a different part of the heart-lung machine) during surgery will help to prevent a decline in mental and neurologic abilities after surgery. investigating 312 patients over 2 years,patients will be assigned randomly to either cardiotomy suction or cell-saver group. Patients will be given questionnaires before surgery, 6 weeks and 1-year after surgery. These questionnaires will assess memory, attention span, the ability to concentrate and the quality of life. Patients will also have a brief neurologic exam (physical examination to check mental state, reflexes, strength, and balance) before surgery, 3-5 days after surgery, 6 weeks and 1-year after surgery to determine any changes. Cell-saver separates red blood cells from tissue waste products and fat prior to returning blood back to the patient and may reduce the negative effects of particles of fat, tissue waste and air bubbles have on the brain. Potential benefits of cell-saver device when used during surgery may prevent the decrease in memory, attention span, and the ability to concentrate resulting in improved quality of life after surgery. Objectives: The primary aim is to determine the effect of continuous flow cell-saver on short and long term neurocognitive function after cardiac surgery, measured by precise preoperative and postoperative psychometric and neurologic testing. Hypothesis: The primary hypothesis: Continuous flow cell-saver reduces postoperative neurocognitive decline following cardiac surgery. Methodology: 312 informed and consenting patients, age > 65 years, scheduled for coronary artery bypass graft surgery will be prospectively enrolled over a 2-year period. Patients will be randomly allocated to either the continuous flow cell-saver or conventional cardiotomy suction (controls). Neurological history and physical exam will be completed preoperatively, discharge, 6-weeks and 1-year after surgery. Transcranial Doppler scanning will be used for intraoperative monitoring of cerebral embolic load. Transesophageal echocardiography and epiaortic scanning will be employed to account for the severity of the aortic atheroma scores. Neurocognitive testing and quality of life assessment will be conducted preoperatively , 6-weeks and 1-year after surgery. Significance: The utilization of continuous flow cell-saver may reduce the negative effects of fat particles, tissue waste and air emboli have on brain.
