Filter by:Noninvasive brain stimulations (NIBS) will be used in MS patients with cognitive impairments to enhance their cognitive aptitudes.
This study will compare the effectiveness of different combinations of 5 types of behavioral interventions across patient-centered outcomes. It will also evaluate which outcomes (e.g. quality of life, cognition, function, mood) matter most to people at risk for dementia and their care partners. The results of this study have the potential to direct patients, families, and health care providers as to which combinations of behavioral interventions provide the greatest potential impact on which dementia prevention outcomes. Greater use of behavioral strategies that are targeted to the outcomes of most important to the patient will likely improve patient compliance and treatment adherence. This, in turn, can lessen the need for medication, health care, and long term care utilization.
The research leading consortium to these results has received funding from the European Union Seventh Framework Programme [FP7/2007-2013] under grant agreement no 602461 (www.biocog.eu). The investigators will establish valid biomarkers panels (neuroimaging and molecular) for risk and clinical outcome prediction of postoperative delirium (POD)/postoperative cognitive deficit (POCD) in elective surgical patients (Age ≥ 65 years) in study centers in Berlin,Germany (data collection within 2 years after initial hospital stay) and Utrecht, The Netherlands (data collection within 1 year after initial hospital stay), thereof cerebrospinal fluid (only once on day of surgery in patients with planned spinal anesthesia/combined spinal epidural analgesia in patients, only in Berlin). A control group of ASA II/III- patients is collected for measuring the learning experience during the cognitive testings. The participants are matched on age, education, and gender to the study patients. The ASA II/III- control patients receive additionally MRI-scan (3 Tesla) at baseline, after 3 months and after 1 (Utrecht) and 2 years (Berlin). To analyze scanner variability we additionally measure at maximum 20 subjects (Age ≥ 65 years, ASA I and II) from Utrecht in the MRI scanner (3-Tesla) in Berlin and vice versa. A study group at maximum (n= 80) and is collected for measuring 7 Tesla MRI at two timepoints (Baseline and 90 days).The primary endponit of this substudy is gamma amino-butyric acid concentration in CNS after 3-months (measured by MRI). A retrospective comparison group (extracting 8000 intensive care unit patient data from the patient data management system during the BioCog study period in 2016) to analyse economic effects that are caused by the implementation of quality indicators in health care. An interim-analysis is performed on the primary endpoint after 400 included patients. The resulting (multivariate) expert system is expected: 1) to support clinical decision-making in patient care, e.g. to balance the individual POD/POCD risk against the expected overall clinical outcome of an (elective) surgical intervention, 2) to allow the design of more sophisticated and hypothesis-driven clinical studies and drug trials (translational research) in the future. The latter will be possible on the basis of biomarker-based sub-grouping of patients and a better understanding of relevant pathophysiological processes. Furthermore, a state-of-the art clinical database and biobank will be created that does not yet exist worldwide. Both the expert system and the reference database/biobank will expand the leadership of the contributing academic institutions in this particular research area. In addition, the newly created biobank will become an integral part of the European Biobanking and Biomolecular Resources Research Infrastructure (BBMRI) which allows top address specific and hypothesis-driven research questions. Most notably, the developed (multivariate) expert system also has the potential for commercialization. Possible customers are: 1) physicians and hospital departments being involved in pre-surgical decision making, 2) pharmaceutical industry intending to conduct biomarker-based drug trials in POD/POCD.
The primary objective is to examine the efficacy of 8-weeks of a locally developed brain-computer interface based system intervention for improving attention and memory in healthy elderly and those with age related cognitive decline. We hypothesize that elderly who have completed the training program will have significant improvement in their attention and memory compared to the controls, based on the Repeatable Battery for the Assessment of Neuropsychological Status.
The primary objective of this preliminary study is to investigate whether the transcranial direct current stimulation (tDCS) improves the cognitive function in patients with Mild Cognitive Impairment (MCI)
Morphine and similar substances (called opioids) are often prescribed for moderate to severe pain, such as after a surgery, thus allowing for minimal pain and a better recovery. Unfortunately various, non-dangerous side effects from opioids occur often that limit the way patients feel and can take of themselves, despite otherwise good pain control and minimal limitations from the surgery itself.
Computer-Based Cognitive Training for Individuals with Parkinson's Disease" is a 3-arm randomized controlled trial (RCT) comparing Brain Fitness, InSight, and an active control (AC) training program to evaluate the feasibility of empirically supported computer-based cognitive training programs (CCTPs) for patients diagnosed with Parkinson's disease (PD) with Mild Cognitive Impairment (MCI). This pilot study aims to address the need for increased interventions to target non-motor symptoms associated with PD.
Deficits in memory, attention, cognitive, and executive functions are the most common disabilities after traumatic brain injury (TBI). Dopamine (DA) neurotransmission is implicated in these neural functions and dopaminergic pathways are recognized to be frequently disrupted after TBI. Methylphenidate increases synaptic DA levels by binding to presynaptic dopamine transporters (DAT) and blocking re-uptake. The objectives of this study are to use PET imaging with [11C]-raclopride, a D2/D3 receptor ligand, before and after administering methylphenidate, to measure endogenous DA release in patients who are experiencing problems with cognition, attention and executive function in the chronic stage after TBI. In addition, we will use TMS to test short intracortical inhibition, a gamma-aminobutyric acid receptor A (GABAA) - mediated phenomenon, which is under partial DA control, as a measure of dopaminergic activity on and off
The purpose of this study is to identify the effects of different doses of dexmedetomidine on postoperative cognitive dysfunction in elderly hypertensive patients
The purpose of this study is to assess the performance of AclarusDx™, an investigational blood test detecting gene expression information, and intended to help physicians in making an Alzheimer's Disease diagnosis in patients having memory complaint and/or cognitive impairments.
