Filter by:This research investigates obesity and associated psychiatric symptoms and disorders in a wide range of perspectives, to demonstrate the effects of obesity on the brain. The 1st aim is to assess the psychiatric symptom profiles in the group of obese patients applying for bariatric surgery and to determine the associated environmental stress factors. While, it is known that eating disorders, mood disorders and psychiatric drugs can cause obesity, obesity can also cause many psychiatric complications such as depression and cognitive disorders. There are no multi-centered studies that are conducted in this respect, and the guidelines on pre-evaluation and follow-up of patients are also lacking. The 2nd aim is to evaluate and monitor cognitive characteristics before and after bariatric surgery in obese patients. Obese people are at increased risk of dementia and are more likely to have cognitive deficits, especially executive function problems, that can affect everyday life. For this reason, obese individuals should be examined and monitored in more detail in terms of their cognitive characteristics and the change of cognitive functions during the weight loss process. The 3rd aim is to examine the relationship between obesity, bariatric surgery and reward processing system. Studies have been limited in determining whether addiction in these people is due to a search of a continuous substance as a cognitive feature or whether it is difficult to terminate it as an impulsive behavior when encountered with a pleasurable substance, even though there is no reward seeking or reward dependence. The 4th aim is the determination of the neuroanatomical and molecular components of cognitive changes observed after bariatric surgery. During the dynamic process following bariatric surgery, a variety of metabolites, chemokines, and microbiota changes may also affect the brain health and cognition. The 5th aim is to determine factors of eating, emotional regulation, reward system, addiction and impulsivity, and other psychopathologies that cause suboptimal weight loss or weight gain after bariatric surgery. Understanding the psychological and neurobiological factors involved in these processes can improve surgical interventions and significantly increase the quality of life for patients.
In the present study the investigators aim to analyze the performance in a battery of social cognition tests of subjects with traumatic brain injury. On the other hand, the effectiveness of a computerized rehabilitation program designed to improve these deficits will be tested, as well as the relationship between social cognition and executive functioning.
The study was aimed to investigate the role of cognition n in FoG.
Scientific evidence regarding the effects of Brain Gym®, on people with cognitive impairment is scarce. This study aimed at comparing the effects of a program based on Brain Gym® exercises against a fitness exercise program on the cognitive function, functional independence, physical fitness and quality of life in institutionalized older adults with cognitive impairment.
This observational cohort study is designed to validate the CogCheck application as a risk prediction tool for postoperative delirium in patients undergoing cardiac surgery.
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.
In this proposal, we will examine processing speed training (PST) as a potential intervention to reduce the risk of developing long-term cognitive impairment after a delirium episode.
The main objective of the study is to analyze the psychometric properties of the "antillanisée" version of the Mini Mental State Examination (MMSEa). The methodology used will permit to explore the feasibility, acceptability, validity and reliability of the tool. The psychometric validation of a version adapted transculturally will increase the value of the results obtained with this test and will make it possible to refine the screening of existing cognitive disorders for elderly subjects with Alzheiner's disease or related disorders.
Background: The transition to long-term care facility can be a stressful and emotional event for the elderly. The evidences showed that the prevalence of depression and the cognition impairment were higher in the institutionalized elderly than the community dwelling elderly. It could affect the quality of life of the elderly and increase risk of mortality. Purpose: The aim of the study is to evaluate the effect of outdoor activities and sunlight exposure on depression, cognitive function, and quality of life among institutionalized elderly. Method: The design is a randomized control trial. Participants will be randomly allocated to experimental or control groups by block randomization. In the experimental group, participants will be encouraged to reduce time spent on bed and bedroom. Nurses, nurse aids or family will take participants outdoors and exposure their face, hands or arm to sunlight for 15-30 minutes a day, five days a week for three months (if the UV index is over 8 according to the forecast of Center Weather Bureau, the participants will be asked to stay inside). In the control group, the participants will receive routine care. The control group will neither be encouraged to stay outdoors nor limit the chance to exposure to sunlight. Expected outcome: The expected benefit of the research is to improve the depression, cognitive function, and quality of life of the institutionalized elderly.
This study concerns elderly patients with cancer with onco-geriatric assessment. This study propose to associate the collection of the results with the Mini-Cog and the CODEX with the passing of the MoCA and the MMS tests, as well as a neuropsychological assessment, in order to determine if the patients have cognitive impairments, to evaluate the sensitivity of these 4 screening tests in elderly patients seeking treatment for their cancer. The results of this study will make it possible, where appropriate, to adapt the practice in the context of oncogeriatric assessment.
