Filter by:The SNIFF 3-Week Aptar Device study will involve using a device to administer insulin or placebo through each participant's nose or intra-nasally. Insulin is a hormone that is produced in the body. It works by lowering levels of glucose (sugar) in the blood. This study is measuring how much insulin the device delivers. In addition, this study will look at the effects of insulin or placebo administered intra-nasally using an intranasal delivery device on memory, blood, and cerebrospinal fluid (CSF).
The investigators aim to study the effects of a 24-week remote-based resistance exercise training program on cardiovascular disease risk factors, cognitive function, and quality of life in older adults living with mild cognitive impairment or Alzheimer's Disease and/or a related dementia. Data for this study will be collected at the beginning, middle, and end of the resistance training program. Participants of this study will receive a baseline health-fitness assessment at the beginning of the study. Measurements of resting blood pressure, fasting blood glucose and lipids, waist and hip circumferences, height and weight, cognitive function and quality of life will be collected at the health-fitness assessment. Participants will then receive supervised remote-based resistance exercise training with Therabands, 3 days per week for 12 weeks before receiving a second 12-week health-fitness assessment in the middle of the intervention. Participants will then receive 12 additional weeks of supervised remote-based resistance exercise training with Therabands, 3 days per week for 12 weeks before receiving a third 24-week health fitness assessment at the end of the study.
Objective: To determine the efficacy of computer-based cognitive training(CBCT) in patients with stroke in the community settings. Study Design: Single-blinded prospective, pre-test/post-test randomized controlled trial (RCT) will be conducted in 2 groups of participants that receiving training in community settings. Treatment groups will attend individualized CBCT programme using CogniPlus® while control group will continue attend conventional treatment as usual (TAU). Assessment on the means difference in assessing functions will be done after the study. Samples: 100 patients with stroke will be recruited from the community, using a sampling frame of selected diagnosis and homogeneity. Expected Findings: Find out the training effects of selected CBCT on EF and daily functioning in patients with stroke
BACKGROUND Neurocognitive symptoms have a high prevalence in cancer patients, resulting in a significant impact on daily life and tolerance to therapy. It's estimated that about 30% of cancer patients present a cognitive impairment before treatment, about 75% present this cognitive impairment during the treatment, and about 35% continue to present cognitive difficulties in the following months/years. There is growing evidence that cognitive symptoms have a biological mechanism linked to the activation of immunological cytokines that exert important effects on the brain functions. For example, interferon α is known to increase the levels of IL-1, IL-6 and TNF-α, and this increase is associated with memory deficits, executive function and mood alterations. A neurotoxic action induced by cytokines has been demonstrated both in the early stages of the tumor and after chemotherapy. Several imaging studies suggest that the cognitive impairment pattern in cancer patients, during the treatment and in remission, is related to structural and functional brain changes. Longitudinal studies in women with breast cancer treated with chemoterapy have shown a reduction in the volume of cerebral gray matter, mainly in the bilateral frontal cortex and hippocampus. In parallel, diffusion tensor imaging studies have shown an alteration of the integrity of the frontal, parietal and occipital cerebral white matter, demyelination and axonal degeneration processes. Finally, functional magnetic resonance studies in cancer patients have shown alterations in the connectivity of the default mode network compared to control subjects. Studies carried out to date, show a prevalent impairment of executive functions and working memory. Cognitive impairment has been studied mainly as a possible adverse effect in women treated with chemotherapy for breast cancer, while there are few studies in the literature on patients with haematological malignancies. STUDY DESIGN The study is targeted to patients ages ≥ 70 years, whith haematological malignancy, who need to start a treatment within 3 months. Once the eligibility criteria have been assessed, the hematologist proposes the enrollment in the study. Once the patient's informed consent has been acquired, a neurological examination is carried out, functional tests required by the protocol are administered. The patient begins, as per clinical practice, the treatment provided for his/her haematological malignancy. Test's evaluation is repeated at 6 months and 12 months after the enrollment. In conjunction with neurological tests, will be performed a venipuncture as per clinical practice, and a blood sample is taken to measure the cytokines involved in inflammatory processes. It is expected that a patient can perform up to a maximum of 3 blood samples for the biological study. STATISTICAL ANALYSIS This is a non-pharmacological, prospective, uncontrolled, open-label single-center interventional pilot study, aimed to describ the progress of cognitive function under treatment for haematological disease. Due to the pilot and exploratory nature of the study and the substantial absence of a specific literature relating to the elderly onco-haematological patient, it is not believed that the conditions exist to be able to formally define the size of the sample. The sample size is arbitrarily fixed at 60 patients. The observation time will be 12 months from enrollment.
This is a phase I, dose-escalation and phase II dose-expansion clinical trial determining the maximum tolerated dose (MTD) and safety and tolerability of adding N-Acetyl-Cysteine (NAC) to ovarian cancer patients who are receiving a platinum-based therapy (PBT). This study will investigate whether NAC will mitigate chemotherapy-related cognitive impairment (CRCI).
In the proposed study, patients with and without embolic protection devices during Transcatheter Aortic Valve Implantation will be repeatedly examined with a comprehensive psychiatric and cognitive test battery over a post-interventional period of 6 months after TAVI, with regard to the effects on mood, cognitive Performance and health-related Quality of life.
The aim of the study is to evaluate the differences in cognitive performance and quality of life, after a cycle of treatment with the relaxometer, between a group of patients affected by fibromyalgia and a control group.
This multicenter, double-blind, Randomized, parallel-group study in subjects with methamphetamine dependence was to assess the efficacy of MBRP combined with vortioxetine and MBRP alone on 24-week abstinence rates, improvement of cognition and depressive symptoms.
The overall objective of this project is to identify the neural signature of the impaired ability to relate socially seen in individuals with schizophrenia. A hypothesized path from the neural processes of social cognition, to social cognition assessed behaviorally, to real-life social interactions is examined. Secondary aims are to compare electrophysiological measures of high vs low level social cognition; to develop assessment methods of real-life behavior; and to increase the ecological validity of schizophrenia research. Much research within the field is devoid of personal meaning and interpersonal context. This project's use of personalized assessment allows for an ecologically valid approach to the social deficits of schizophrenia.
Background: Dynamic balance keeps the vertical projection of the center of mass within the base of support while the center of mass moves. The age-related decrease in dynamic balance is a risk factor for falls. Dynamic balance tests are used to predict the risks for falls and eventual falls but the psychometric properties of most tests assessing dynamic balance are unsatisfactory and comprise no actual loss of balance while walking. Objectives: Using beam walking distance as a measure of dynamic balance, we will determine the psychometric properties, lifespan and patient reference values, the relationship with selected 'dynamic balance tests', and the accuracy of beam walking distance to predict falls. Methods: This cross-sectional observational study will examine healthy adults in 7 decades (n=432) at 4 centers. Center 5 will examine patients (n=100) diagnosed with Parkinson's disease, multiple sclerosis, stroke, and balance disorders. At Test 1, all participants will be measured for demographics, medical history, grip and leg strength, short physical performance battery, static balance on a force platform, and dynamic balance using beam walking (4m-long, 4, 8, and 12 cm wide) under single (beam walking only) and dual task conditions (beam walking while concurrently performing an arithmetic task). In addition, cognitive function (global cognition, attention, executive function, processing speed, memory) will be assessed. Patients and healthy participants age 50+ will be additionally measured for fear of falling, history of falls, miniBESTest, functional reach on a force platform, timed up and go, and reactive balance. At Test 2, 7-10 days after Test 1, healthy adults young and age 50+ (n=40) will be re-tested for reliability of beam walking performance. All participants age 50+ will be re-called to report fear of falling and fall history 6 and 12 months after Test 1. Conclusion: The investigators expect to find that beam walking performance vis-à-vis the traditionally used balance outcomes predicts more accurately fall risks and falls.
