Filter by:The purposes of this study are to determine whether long-term postoperative cognitive dysfunction (POCD) is occured after general anesthesia and anesthetic drugs have an effect on the result about POCD.
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)
The purpose of this study is to identify the effects of different doses of dexmedetomidine on postoperative cognitive dysfunction in elderly hypertensive patients
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.
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.
This study is to explore the effects of dexmedetomidine on postoperative cognitive dysfunction during one-lung ventilation in elder patients.
The primary aim is to collect data to determine the correct effect size on the primary outcome to aid in the design of a larger study: The primary outcome is to determine if lipoic acid and omega-3 fatty acids can improve cognitive function in people with multiple sclerosis that have cognitive dysfunction.
The aim of the current study is to evaluate, in a prospective cross-over, randomized study, the effect of hyperbaric oxygen therapy (HBOT) on patients with chronic impairment after low grade glioma tumor removal surgery
The proposed study aims to explore brain mechanisms mediating the cognitive benefits of aerobic exercise in patients with mild cognitive impairment- a prodromal stage of Alzheimer disease. We will perform FMRI experiments, as well as laboratory and behavioral tests that will advance our knowledge about the nature of these mechanisms. Participants will participate in individual- tailored aerobic training program. Pre and post evaluation will identify brain changes following the training using advanced techniques of brain imaging. Cognitive performance will be assessed prior and at the end of the program, as well as endocrine markers reflecting improvement in learning abilities. Moreover, demonstrating cortical plasticity in subjects with aMCI has tremendous practical significance for these subjects .
People with schizophrenia tend to have problems with attention and concentration. Studies found that these patients are unable to block or gate out non-relevant and distracting information (e.g., noises). This may lead to brain overload. Cognitive abilities like concentration, memory, and learning may worsen. This ability to filter sensory information has been linked to a gene that affects the way nicotine acts in the brain. Patients with schizophrenia have a high rate of cigarette smoking. 60% to 90% smoke compared with 25% of the general population. It has been suggested that these patients may use nicotine to improve their ability to block out distracting information. Brain wave activity (EEG) in response to sounds has been proved useful in understanding this gating problem. The present study uses EEG measures and performance tasks to find out what a new nicotine-like treatment, which will be added to ongoing treatment medications, does to gating and cognition. It is hoped that this new treatment will improve the way in which patients process information, as this may help them in day-to-day activities.
