Active clinical trials for "Cognition Disorders"

In the context of reduce staff for supervision of dependent elderly, automated risk alert systems could have a positive impact on the organization of night care by better targeting monitoring. Residents' sleep could be less affected with use of automatic alert system than by systematic monitoring visits. One study shows an improvement in the humor of residents after the use of such a system. The hypothesis of the study is that the use of a bed-raising detection system linked with the activation of a lighting environment and a caregivers alert system (Etolya-F® gerontechnology device, Anaxi Technology Company) would reduce intervention time in this population, thus limiting the time spent on floor and its physical and psychological consequences.

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.

This study is aimed at examining the interest of amyloid radiotracer Florbetapir (18F-AV-45) for the etiological diagnosis of poststroke cognitive impairment and dementia

This registry will be used to identify patients who have etiology diagnosed or suspected to be Alzheimer's disease and positive amyloid scans, and have indicated their interest in being contacted for an Eli Lilly and Company (Lilly) Alzheimer's Disease drug research trial.

The investigators aim to test the feasibility of a pragmatic non-pharmacological strategy, that may prevent cognitive decline in patients with mild cognitive impairment. This strategy is based on five different interventions: cognitive training, physical activity, nutrition education, adaption to memory loss, diagnosis and correction of hearing impairment. A quasi-experimental study will be implemented in Porto (Portugal), including patients that fulfill all of the following criteria: a) age 18-85 years; b) Montreal Cognitive Assessment (MoCA) score greater than or equal to two standard deviations below the normative reference value for the corresponding age and education level in the Portuguese population OR diagnosis of Mild Cognitive Impairment, performed by a Neurologist, during the six previous months, considering the results of a neuropsychological battery; c) Cardiovascular Risk Factors, Aging and Dementia (CAIDE) Dementia Risk Score of at least six points. Patients who have any medical disability that contraindicates physical activity or have a lack of autonomy in daily activities will be excluded. The program will be implemented in groups of 10 participants, over a period of 10 consecutive months.

Cognitive disorders are common early after stroke but can be overseen in patients with mild stroke who seem to be functionally recovered but are at risk to experience difficulties in advanced daily activities affecting social, vocational and family responsibilities. Acute stroke units admit a large number of patients and adequate referral to rehabilitation services is essential in terms of quality of care. A self-evaluation tool to evaluate cognitive function was developed by the occupational therapy department. Patients with mild strokes and pre-stroke independent for instrumental daily activities fill out this self-evaluation tool, which is a paperwork task. Semi-structured interpretation is performed by physician and may result in referral to the occupational therapist for comprehensive evaluation. In this study the validity and reliability of the self-evaluation tool will be examined.

The study objective is to correlate global cognition and episodic memory performance to resting state fMRI functional connectivity. This is a non-treatment, prospective, natural history data collection study in a cross-sectional cohort of patients with cognitive impairment.

Background: In a national Norwegian cohort of children born before 28 weeks gestation or with a birth weight less than 1000 g born in 1999 and 2000, 372 survived. Compared with earlier studies survival increased for the most immature infants, but at the cost of more early complications and a high rate of impairments, while the less immature children had fewer early complications and less impairments detectable within 5 years. These changes show the importance of monitoring outcome as treatment modalities change. Large brain haemorrhages were highly predictive of severe disabilities, but we have not found good predictive factors for milder impairments such as cognitive, behavioural and motor difficulties. However, at 5 years later function may be difficult to predict, and the children's potentials are better understood after completing several years in school. Objectives: The children will be re-examined at age 11 in order to assess their physical and mental health, and cognitive, motor and social function, and to determine if early life events and development at 2 and 5 years are predictive of long term health and functioning. MRI-studies, including functional MRI will be performed to examine if different outcomes related to brain function can be explained by differences in brain development. Methods: For all, data will be collected from the compulsory national test in 5th grade and questionnaires to the child, parents and teacher. For children in Western Norway (n=87) extensive examinations of lung and brain function, including clinical diagnostic tests and MRI, will be added. For all aspects of the study the investigators have appropriate current and historic reference populations for comparison. Implications: Knowledge on causes and of early predictions of outcome is needed to give appropriate advice to families, professionals and society, and to develop preventive programs.
