Filter by:The EuRIDICE trial will study whether haloperidol as a first line treatment for ICU delirium reduces delirium duration (and severity). Adverse outcomes typically associated with delirium will also be studied and include long term cognition, functional outcome and quality of life. Further, patient and family experiences and cost-effectiveness will be assessed. Finally, safety concerns associated with the use of haloperidol in this vulnerable population will be studied.
This is an interventional clinical trial that will be conducted as a pilot project. Investigators hope to conduct the study to obtain at least 10 study completers. The plan is to screen 20 Parkinson's Disease (PD) patients attending the Academic Health Care Center (AHCC) at NYIT College of Osteopathic Medicine clinic and enroll the eligible candidates based on the inclusion and exclusion criteria. Subjects will have 11 study visits over the 11-week period. Subjects cognition will be assessed using a paper-based Test of Memory and Learning (TOMAL) tool. The same tool will be used to asses and compare the cognition at baseline, and end study visits. The weekly 30-mins of cognitive remediation exercises will be done using the Brain.

Cognitive difficulties such as indecisiveness or inability to concentrate are core symptoms of depression with up to 90% of untreated depressed individuals experiencing these symptoms. As many as half of those who remit from a major depressive episode continue to experience residual cognitive deficits, but these symptoms are frequently overlooked in clinical practice. This leads to persistent cognitive deficits which can cause reduced level of functioning and loss of productivity. As standard antidepressants have an inadequate impact on these residual cognitive symptoms, further treatment options are required. Modafinil is a wakefulness agent with evidence that it improves some domains in cognition such as memory in those whose non-cognitive depressive symptoms have been treated over a short term period. This medication may have favourable lasting effects on cognition, such as the ability to plan and execute tasks in those who receive modafinil for a longer time period. The aim of this study is to investigate whether modafinil can enhance cognition and have additional effects on functioning and work productivity in a sample of participants who were treated for depression but who continue to experience cognitive deficits.
Older people are a rapidly growing proportion of the world's population and their number is expected to increase twofold by 2050. When these people become patients that require surgery, they are at particular high risk for postoperative delirium (POD), which is associated with longer hospital stays, higher costs, risk for delayed complications and cognitive dysfunction (POCD). Having suffered an episode of delirium is furthermore a predictor of long-term care dependency. Despite these risks, an increasing number of elderly undergo major elective surgery. This is reflected by the frequency of elective spinal surgery, in general, and instrumented fusions, in particular, which has markedly increased over the past few decades. It is yet insufficiently understood, which, particularly modifiable, factors contribute to the development of POD and POCD following these major but plannable surgeries. A better understanding of risk factors would facilitate informed patient decisions and surgical strategies could be tailored to individual risk profiles.
The present observational study is aimed at reporting the short-, mid- and long-term outcomes of patients with Disorder of Consciousness (DOC), in Vegetative State (VS) or Minimally Conscious State (MCS), due to a severe Acquired Brain Injury (sABI), after repeated treatments with anodal Transcranial Direct Current Stimulation (tDCS) on Left Dorsolateral Prefrontal Cortex (L-DLPFC), to stimulate recovery of consciousness. The results obtained will also be compared with those of a historical control cohort, before the introduction of tDCS, matched for demographic and clinical characteristics.
Postoperative Cognitive Dysfunction (POCD) is a state of decline in cognitive ability after surgery and is frequently seen among our elderly population. Many studies have looked into predictive risk factors for POCD while research is underway to search for pre-emptive measures to avoid this unfavourable outcome. Most will be looking at utilizing mobile software applications of cognitive training but in many poorer countries, owning electronic devices may not be an option or may be culturally less acceptable among the older patients. Hence, the investigators intend to investigate if a home-based logbook for cognitive training will reduce the incidence of POCD in a single centre study.
The purpose of this study is to determine what percentage of patients have cognitive problems (for example, memory or concentration difficulties) after surgery and anesthesia, what the characteristics of these problems are, and whether they persist over time. In particular, the investigators want to study this in the French-speaking Quebec population with cognitive evaluation tools adapted for this population.
The purpose of this study is to test the effects of tDCS (Transcranial Direct Current Stimulation) on stroke patients with working memory problems.
The primary objective of this multicenter observational study is to determine the effect size of the relationship between DCI and neuropsychological impairment 14-28 days and 3 months after aSAH. Secondary objectives are the feasibility to administer and the validity of the MoCA in an intensive care unit setting, as well as the test/retest reliability of the MoCA in patients with acute brain damage in absence of aSAH.
The hypothesis is that structured preoperative cognitive screening of seniors is feasible without specialized staff and can help preoperatively identify persons at high risk of complications. To demonstrate generalizability of the single center experience, and strengthen the case for routine preoperative cognitive screening of seniors, the aims of this proposal are to implement preoperative cognitive screening of seniors in the preoperative clinics of a community hospital (NWH) and a 2nd tertiary care institution (MGH); and determine whether impairment is an independent predictor of adverse perioperative events.
