Filter by:Cognitive impairment is a core symptom of schizophrenia and is in a large part responsible for the poor psychosocial outcome of the disorder. The use of non-invasive brain stimulation techniques as a therapeutic option is just commencing for neuropsychiatric patients. Concerning healthy subjects the investigators have previously shown that anodal tDCS to the right dorsolateral prefrontal cortex (DLPFC) parallel to working memory training can sustainingly enhance performance in a spatial n-back task. Additionally, first translational experiments regarding the use of anodal tDCS to improve working memory (WM) in patients with schizophrenia rendered promising results. On those grounds, the investigators now test the hypothesis that anodal tDCS to the right DLPFC can augment working memory training in patients with schizophrenia.
This study is a sub-study to the large pragmatic Target Temperature Management 2 Trial (TTM2-trial, ClinicalTrials.gov Identifier: NCT02908308), assessing effectiveness of controlled hypothermia after out-of-hospital cardiac arrest (OHCA). This study is designed to provide detailed information on cognition after OHCA and its relationship to associated factors as emotional function, fatigue, and sleep. A secondary aim is to utilize this information to validate a neurocognitive screening battery used 6 months after OHCA in the TTM2-trial. Approximately 7 and 24 months after OHCA, survivors at selected TTM2 study sites will perform a standardized neuropsychological assessment including performance-based tests of cognition and questionnaires of behavioral and emotional function, fatigue, and insomnia. At 1:1 ratio, a control group of myocardial infarction (MI) patients but no occurrence of cardiac arrest will be recruited and perform the same test battery. Group differences at 7 and 24 months will be analyzed per cognitive domain (verbal, visual/constructive, short-term working memory, episodic memory, processing speed, executive functions). Results of the OHCA survivors on the TTM2 neurocognitive screening battery will be compared with neuropsychological test results at 7 months time.
This study seeks to evaluate the efficacy and safety of NA-83 in subjects with mild cognitive impairment due to Alzheimer's Disease
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.
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 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.
Post-operative cognitive dysfunction is defined as a decrease in cognitive functions which develop following surgery and anesthesia administration that can last up to weeks or even months after surgery. In this study, our main objective was to investigate the effect of preoperative hospitalisation period on early post operative cognitive dysfunction development and its risk factors in patients who underwent total hip replacement surgery for hip fractures under regional anesthesia.
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.
