Active clinical trials for "Cognitive Dysfunction"

To study on the Postoperative Cognitive Dysfunction: Correlations With Olfactory Dysfunction and Related Gene Changes.To explore whether the olfactory dysfunction could be used as a predictor of POCD and to provide reference for POCD prevention, early detection and timely diagnosis and treatment.

This study will recruit surgical patients more than 65 years old. Patients who participate will wear a sticker on their forehead during surgery which monitors their brain waves (electroencephalogram, EEG) and participate in memory testing before and after surgery. Brain wave patterns will be compared between patients who have problems with memory and thinking after surgery and those who do not. The hypothesis is that there will be characteristic brain wave patients for who will go on to have problems with memory and thinking after surgery.

This study aims to investigate the in-hospital care as well as the cognitive status, quality of life, physical function and risk of anxiety and depression, sleep disorders and drug use in a Danish cohort of both medical and surgical patients with acute critical illness without admittance to ICU (Intensive Care Unit) treatment, at three and twelve months after hospital discharge.

The objective of this prospective study is to evaluate the prevalence of neurocognitive impairments in HIV infected patients comparing patients with and without HAART. Recent studies have demonstrated a specific HIV infected patients neurocognitive disorders profile. These cognitive disorders concern primarily information processing speed, memory recall, attentional abilities, work related memory, executive functions, and psychometrical speed. This cognitive profile is similar to another highly documented one, described for another central nervous system disease (CNS): multiple sclerosis. In both CNS diseases, the earliest and most severe disorder is the one related to the information processing speed. For the multiple sclerosis patients, a short cognitive test (SDMT) is actually used not only to identify cognitive disorders presence, but also in order to predict a long term disability worsening. A digital version of this test (CSCT), has recently been developed in order to make this early evaluation easier. We hypothesize that CSCT alteration would also predict HAND, in HIV infected patients. A complete neuropsychological assessment is highly time and personal consuming. This short (approximatively 2 minutes) digital test would be highly helpful to identify patients, who will need a more extensive neuropsychological assessment.

Adequate pain therapy is important aspect of perioperative care. Sequelae of inadequate pain management are patient dissatisfaction, post-operative nausea and vomiting (PONV), inadequate nutrition, lack of mobilization, and an increased risk for the development of further complications, such as postoperative delirium (POD). The use of patient-controlled analgesia (PCA) systems, which allow patients to self-administer analgesics, has improved pain management. Conventional i.v. PCA and the non-invasive administration of sufentanil sublingual tablets (ZALVISO®) are available. The aim of this investigation is to study patient controlled analgesia systems and to examine the incidence of POD, POCD and postoperative pain.

The main purpose of this study is to explore the impact of an amyloid positron emission tomography and computed tomography (PET/CT) scan on physician diagnosis and management, including drug management and care practices, for patients with a diagnosis of cognitive impairment. This study also intends to capture specific patient-reported outcomes related to patient burden, confidence and satisfaction. The hypothesis is that to aid early diagnosis, individuals with a diagnostically uncertain etiology for their dementia will benefit from knowledge of amyloid plaque burden status, through an alteration of patient diagnosis and management, which will lead to significant changes in patient and care partner reported outcomes.

The purpose of this study is to identify association between cerebrospinal fluid Alzheimer's Disease's neurodegenerescence biomarkers (tau, ptau, Aß40 and Aß1-42) and occurrence of cognitive deficits in older patients with bipolar disorders.

Postoperative cognitive dysfunction (POCD) describes a condition where cognitive functions such as attention, perception, concentration, learning, abstract thinking and problem solving are impaired postoperatively. These changes can be resolved after weeks and months. In some cases, changes are permanent.

The diagnostic and therapeutic progresses, associated with modifications in lifestyle and socio-cultural level of populations, have led to a remarkable increase in life expectancy. At the same time, the increasing medicalization of the individual has eroded the traditional boundaries between health and illness, normal and pathological state. This leads to the patient losing his sense of ownership of his own death. If most patients died at home before the Second World War, 75% of the population dies in hospital or institution at the present date. Most hospitals and care institutions have developed codes, in multidisciplinary internal consultation, to address the interruption or lack of implementation of treatments that make no sense from a medical point of vue. This avoids therapeutic relentlessness.The code in place within the CHU Brugmann is: code A: no therapeutic restriction code B: not to be resuscitated code C: not to be intensively treated (no escalation in therapeutic treatments) code D: best palliative care (progressive de-escalation in therapeutic treatments). These codes are established in consultation with the patient or his legal representative and are re-evaluated in a multidisciplinary way every week. Planning a care path and therefore establishing a therapeutic code is particularly important for people with cognitive impairment and dementia because the progressive loss of cognitive abilities complicates the process of decision making. A large part of the admissions are made via the emergency department. For these patients, no therapeutic plan has been established beforehand. However, the perception of the functional and cognitive status of the patient directly influences the intensity of care provided. Cognitive disorders are a risk factor for the exclusion of access to palliative care for the elderly patient. The objectives of this study are: To establish a record of the therapeutic limitation codes in an acute cognitive geriatric unit To correlate the therapeutic limitation code with the comorbidities of the patients

Patients who are frail will have higher rate for post-operative morbidities, mortality, prolonged hospital stays, loss of independence, increase in institutionalization, post-operative cognitive dysfunction (POCD) and delirium (POD). So, it is crucial to find a suitable frailty assessment tool that can be incorporated into a guideline and reference for our local setting in geriatric peri-operative management. In the mean time, create awareness regarding the frailty elderly population with POD, POCD and other associated poor outcomes among our clinicians.
