54 active trials for Cognitive Change

The Norwegian Prednisolone in Early Psychosis Study

Objective: The primary objective of this trial is to investigate whether prednisolone improves symptom severity as compared to placebo when given in addition to antipsychotic medication to patients with early-stage psychotic disorder. Secondary objectives include improvement of cognitive functioning and positive, negative and general psychopathological symptoms as well as general functioning. Study design: Randomized placebo-controlled double-blind trial. Study population: 90 men and women, with an age of 18 years and older, diagnosed with schizophrenia spectrum disorder. The time interval between the onset of psychosis and study entry should not exceed five years and CRP level should be at least 3.9 mg/L. Intervention: Patients will be randomized 1:1 to either prednisolone or placebo daily for a period of 6 weeks. Identical tablets will be administered. Prednisolone will be initiated at 40 mg for three days, after which it will be phased out within 6 weeks after start, following current treatment guidelines. Main study parameters/endpoints: Primary outcome is change in symptom severity, expressed as a change in total score on the Positive and Negative Symptom Scale (PANSS) from baseline to end of the 6-week treatment. Secondary outcomes are a 6-month follow-up assessment of PANSS, cognitive functioning (measured through a repeatable neurocognitive battery, change in GAF scores and the measurement of various immunological biomarkers. In post-hoc analyses, attempts will be made to identify baseline blood markers with predictive properties regarding improvement in the anti-inflammatory drug treatment arm. Expected benefits for consumers and care givers: A decrease in symptom severity is expected, as low grade brain inflammation may be associated with psychotic symptoms. The results may give raise to a new line of scientific research as well as treatment options for a disabling disorder.

Cognitive Changes After Major Joint Replacement - Full Trial (Cognigram 2)

Patients assume that cognitive performance rapidly returns to baseline after anesthesia and surgery. Several studies have shown that one week after major non-cardiac surgery about 27% of patients have postoperative cognitive dysfunction (POCD) and 10% of patients at 3 months. Very few studies have assessed the incidence of POCD beyond 3 months. POCD significantly reduces quality of life. Identifying risk factors for POCD is important because it is associated with prolonged hospital stay, loss of independence, and premature retirement. There is an urgent need to measure and document the level of cognitive change associated with surgery with an easy to use tool, both prior to admission and after discharge. This information can be used to plan appropriate care paths and to identify or test the efficacy of potential new treatments to alter the negative trajectory.

Health, Wellbeing and Performance in Law Enforcement Workers

This study aims to assess current health and fitness of law enforcement workers in various roles, and to evaluate the impact of an exercise intervention on markers on physical and mental wellbeing in this population. The intervention will consist of an exercise programme specifically targeted at improving, physical fitness and reducing musculoskeletal pain. Participants will be randomised to three groups: a face to face intervention group, an online intervention group an a control group. Self-reported physical health, musculoskeletal complaints, quality of sleep and occupational stress will be measured via questionnaires. Pre and post measures of fitness will be measured via functional strength testing and a cardiopulmonary exercise test. Pre and post cognitive function will be measured via computer-based cognitive tests and brain functional near-infrared spectroscopy (fNIRS). Systemic inflammation will be measured via hsCRP. Risk of typeII diabetes will be measured via HbA1c. Daily physical activity and quality of sleep will be measured via accelerometry and heart rate telemetry. It is hypothesised that, upon completion of the programme, there will be an improvement in cardiovascular fitness and physical strength, reduced musculoskeletal pain, improved cognitive readiness and improved overall mental health and wellbeing.

Exercise and Learning and Memory in Multiple Sclerosis

The two primary study objectives involve examining the effects of treadmill walking exercise training versus stretching-and-toning activities on the primary and secondary outcomes. Specific Aim 1: The first specific aim is to examine the effects of 3-months of treadmill walking exercise training compared with an active control condition on learning and memory outcomes in fully-ambulatory persons with MS who have impairment in learning new information. We hypothesize that those who undergo treadmill walking exercise training will demonstrate improvements in learning and memory relative to those who undergo stretching-and-toning activities. Specific Aim 2: The second specific aim is to examine the effects of 3-months of treadmill walking exercise training compared with an active control condition on hippocampal volume, hippocampal resting-state functional connectivity, and cardiorespiratory fitness in those persons with MS. We hypothesize that those who are randomly assigned to the treadmill walking exercise condition will demonstrate increases in hippocampal volume and resting-state functional connectivity (i.e., adaptive increases) and improved cardiorespiratory fitness relative to those in the stretching-and-toning condition.

Effects of Pulsed Electromagnetic Fields (PEMFS) On Cerebral Haemodynamics

The investigators are looking to determine the effects of PEMFs device on cerebral blood flow and cognition in healthy volunteers. Through in vitro tests and in vivo animal studies, the investigators have shown that at an extremely low flux density (strength) of 1 millitesla (mT) and with short exposures of 10 minutes a week, PEMFs can recapitulate many of the healthful benefits of exercise without imparting a mechanical stress on the tissues and cells. In the first-in-man study, 10 healthy volunteers were exposed to PEMFs for 6 weeks with 10 minutes of field exposure per week, and experienced an average increase of 30% in leg strength. No side effects were reported. In this study, the investigators aim to understand the cerebral effects of an exercise mimetic (PEMFs) via the muscle milieu.

CBT Based Group Therapy for Patients With Chronic Fatigue Syndrome (CFS)

Chronic fatigue syndrome is a severe medical condition. It is characterized by long term fatique and other persisted symptoms, such as a cognitive disabilities and orthostatic intolerance. Symptoms limit a persons ability to carry out ordinary daily activities. In ICD- 10, disease is known as G93.3, postviral fatigue syndrome. The purpose of this research (doctoral study) is to produce a psychological, cognitive behavioral therapy (CBT) based group intervention for CFS- patients. Research protocol: 70-80 patients with diagnosis G 93.3. Psychological and psychiatric evaluation for patients (SCID I and parts from SCID II). Depression diagnosis is allowed (on remission). Medication for depression is also allowed. Measurements for ortostathic intolerance (Somnotouch nimbTM) and laboratory measurements: complete blood count, CRP, alkaline phosphatase, GT, ALAT, CK, bilirubin, kidney and thyroid (TSH, T4V) function tests, serum ferritin, glucose, electrolytes and daily urine sodium excretion. Autonomic nervous system ganglio antibodies: Anti-AT1R- Antibodies, Anti- ETAR- Antibodies, anti alpha-1 adrenergic Receptor Antibodies, anti alpha 2 adrenergic Receptor Antibodies, anti beta-1 adrenergic Receptor Antibodies, anti beta-2-adrenergic Receptor Antibodies, anti- Muscarinic Cholinergic Receptor 1 (M1)- Antibodies, anti- Muscarinic Cholinergic Receptor 2 (M2)- Antibodies, anti- Muscarinic Cholinergic Receptor 3 (M3)- Antibodies, anti- Muscarinic Cholinergic Receptor 4 (M4)- Antibodies, anti- Muscarinic Cholinergic Receptor 5 (M5)- Antibodies.

Enhanced Stress Resilience Training for Residents

Burnout and overwhelming stress are growing issues in medicine and are associated with mental illness, performance deficits and diminished patient care. Among surgical trainees, high dispositional mindfulness decreases these risks by 75% or more, and formal mindfulness training has been shown feasible and acceptable. In other high-stress populations formal mindfulness training has improved well-being, stress, cognition and performance, yet the ability of such training to mitigate stress and burnout across medical specialties, or to affect improvements in the cognition and performance of physicians, remains unknown. To address these gaps and thereby promote the wider adoption of contemplative practices within medical training, investigators have developed Enhanced Stress Resilience Training, a modified form of MBSR - streamlined, tailored and contextualized for physicians and trainees. Investigators propose to test Enhanced Stress Resilience Training (ESRT), versus active control and residency-as-usual, in surgical and non-surgical residents evaluated for well-being, cognition and performance changes at baseline, post-intervention and six-month follow-up.

Acute Cognitive Changes During Atrial Fibrillation Episodes (AFCOG)

Objectives: First, to determine if patients with a history of AF have acute measurable changes in cognitive functioning while in an episode of AF. Second, to collect basic insight into what specific physiologic (blood pressure, pulse oximetry, heart rate, temperature) and pharmacologic (antiarrhythmic medications, rate control medications, anticoagulants, antiplatelet medications, etc.) factors minimize the neurological impact on patients while they are in AF. It is hypothesized that when using a tablet-based cognitive testing software - Cambridge Cognition (specifically to assess executive function, learning and working memory: Rapid Visual Information Processing test, Spatial Working Memory/Spatial Span Task tests, One touch Stockings of Cambridge test, Cambridge Gambling Task, Multitasking Test/Intra-Extra Dimensional Set shift tests) - a significant difference will be noted between how the patients perform while in atrial fibrillation compared to the patients' performance while in normal sinus rhythm.
