Active clinical trials for "Cognitive Dysfunction"

This implementation study will be conducted to test a Socially-Assistive Robot (SAR) system for residents in an Assisted Living environment. The goal of the SAR system is to enhance social engagement and connectedness. The system engages residents via robot-facilitated activities such as trivia and reminder and is integrated with the SimpleC Wellness Platform.

Clinical and epidemiological studies suggest links between cognitive impairments and Type 2 diabetes (T2DM). The underlying mechanisms and causality in diabetes-related cognitive impairment are largely unknown. The aim of this study is to investigate cognitive impairment and the role of BDNF in prediabetes and diabetes patients.

The purpose of this study is to determine the effectiveness of EGb 761® (Tanakan®) in Russian patients of middle age and younger, suffering from psycho-emotional symptoms added to cognitive disorders based on the improvement of FAM test (feeling-healthy, activity, mood test) score.

The goal of this pilot study is to develop and implement a larger scale, multi-site stepped collaborative care trial that targets injured patients with presentations of posttraumatic stress disorder (PTSD) and related comorbidities.

The purpose of this study is to analyze the Ketamine with its anti-inflammatory profile would be able to prevent cognitive disorders in the postoperative period of cardiac surgery, since these disorders contribute to an impact on morbidity / mortality in this population.

The objectives of this pilot study are: to determine whether a short cognitive test battery administered in the preadmission test center can be used to cognitively stratify elderly patients presenting for elective surgical procedures. to evaluate the cost of cognitive screening in the preoperative testing center in terms of time and finances. to evaluate patient perceptions about the use of preoperative cognitive screening and their outcome expectations from their surgical procedure. Subsequent investigations may evaluate whether preoperative cognitive screening is a predictor of postoperative morbidity and mortality in elderly surgical patients and whether a short cognitive screen administered in the preadmission testing center could be used to identify individuals with baseline cognitive impairments that should be refered for more formal cognitive evaluation.

The purpose of this pilot study is to test whether 6 months of supervised weekly Kundalini yoga classes and a brief daily meditation homework assignment can improve memory and thinking in older adults with mild memory complaints when compared to weekly classes of memory training with daily homework assignments.

DESCRIPTION OF RELATED QUESTION Cognitive disorders are frequently encountered and present a major public health problem given the aging of the population. There is not one, but several neurodegenerative pathologies individual differentiated. Particularly distinguished is Alzheimer's disease (the most common), dementia lobar fronto-temporal associated with semantic dementia (a disease with a particular tropism for semantic memory and the anterior temporal lobe), and dementia with Lewy bodies. To differentiate these pathologies is, for the clinician, is a major issue and the clinic may not be enough. The management and current diagnostics of atypical cognitive disorders, that is to say, patients with clinical symptoms or neuropsychological testing results suggestive of a neurodegenerative disorder other than Alzheimer's disease, are based largely on data imaging. In the first intention, conducting imaging by MRI is recommended by the HAS, particularly to search for treatable causes to these cognitive disorders (tumors, intracranial hemorrhage in particular) but also to study the distribution of cerebral atrophy. The sequences used are the sequences 3D T1, axial Flair, gradient echo axial T2 and coronal T2 in the plane of hippocampi and also diffusion imaging. Research has shown interest in the study of cerebral perfusion in cognitive disorders. The HAS recommends not to inject contrast medium on MRI in this context. The sequence of perfusion by tagging arterial protons or "arterial spin labeling" (ASL) does not use exogenous contrast medium. This is available as a commercial product, CE marked, on most of the recent clinical MRI scanners. This non-invasive technique, requiring no special precautions (e.g. verification of renal function) is used in routine clinical practice at the University Hospital of Rennes and in many centers. In the imaging of patients with dementia, it is widely used as well as the 3D T1 sequences or diffusion imaging (International Initiative ADNI) and is subject to optimization and harmonization of use in routine clinical practice with the European COST AID actions. The second intention, an isotope imaging by FDG-PET or study of perfusion SPECT can also be performed. The interest of isotopic imaging (FDG-PET and SPECT) lies in the provision of information metabolic nonexistent in MRI, with a superiority of FDG-PET compared with SPECT. FDG-PET is the preferred examination and is carried out at CRLCC Eugène Marquis de Rennes in this context. The aim of our study is to compare the imaging of TEPFDG, a technique not morphological, and ASL that, even if they do not study the same mode (metabolism for the first and perfusion for the second) may depict consistent anomalies.

The purpose of this study is to determine whether a home care medication management program which includes nurse coordination and use of the MD.2 medication-dispensing machine will affect older adults' health outcomes, satisfaction, use of health care services, and health care costs over a one year period. The investigators propose a longitudinal three group repeated measures design, enrolling, and randomly assigning, clients who are discharged from a home health care agency with documented problems in medication management. One group will receive the MD.2 medication dispensing device and nurse coordination, the second group will receive a Medplanner: a simple box that has separate compartments for individual medication times over the course of a week plus nurse coordination, and the final group will receive Usual Care. The study hypotheses are the following: H1: With respect to health status outcomes, the MD.2 group will exhibit a more positive trajectory in physical and mental health status, functional status, cognitive status and depressive symptoms over the course of a year than will the Medplanner Group. H2: With respect to health status outcomes, the Medplanner Group will exhibit a more positive trajectory in physical and mental health status, functional status, cognitive status and depressive symptoms over the course of a year than will the Usual Care Group. H3: The rate of hospitalization, hospital days and emergency department visits will be significantly lower for the MD.2 Group as compared to the Medplanner Group. H4: The rate of hospitalization, hospital days and emergency department visits will be significantly lower for the Medplanner Group as compared to the Usual Care Group. H5: The nursing home admission rate will be significantly lower for the MD.2 Group as compared to the Medplanner Group. H6: The nursing home admission rate will be significantly lower for the Medplanner Group as compared to the Usual Care Group. H7: The total cost of care will be significantly lower for the MD.2 Group as compared to the Medplanner Group. H8: The total cost of care will be significantly lower for the Medplanner Group as compared to The Usual Care Group. H9: There will be incremental savings in terms of costs per quality adjusted life year (QALY) gained in the MD.2 group compared with the Medplanner Group. H10: There will be incremental savings in terms of costs per QALY gained in the Medplanner group compared with the Usual Care Group.

Fibromyalgia is a common rheumatologic disorder. Many patients complain of cognitive dysfunction as part of their symptoms. The investigators aim to assess this cognitive dysfunction through extensive neuro-cognitive testing.
