Active clinical trials for "Cognitive Dysfunction"

The purpose of this study is to test the effects of long-term therapeutic doses of formoterol, on a) cerebrospinal fluid (CSF) tau levels, and Amyloid Beta protein 40/42 levels in the CSF, and b) cognitive function in people with mild to moderate Alzheimer' Disease (AD).

Meta-analyses indicate beneficial effects of cognitive training and cognitively challenging video games on cognition. However, cognitive effects of solving jigsaw puzzles - a popular, visuospatial cognitive leisure activity - have not been investigated, yet. Thus, the primary aim of this study is to evaluate the effect of solving jigsaw puzzles on visuospatial cognition. As secondary aims, effects on psychological outcomes (self-efficacy, perceived stress, well-being) and visuospatial everyday functioning (instrumental activities of daily living and self-reported cognitive failures in everyday life) are examined.

This study is designed to test the hypothesis that closed loop system reduces post operative cognitive dysfunction incidence 15 min after anesthesia more than desflurane, sevorane, total intravenous anesthesia manually guided by bispectral index in urologic surgical patients. The secondary aim is to evaluate the postoperative cognitive impairment in in elderly vs younger surgical patients.

The goal of this study is to determine whether increasing participation in cognitive, physical, and/or social activities prevents cognitive decline in older African Americans (AAs) with Mild Cognitive Impairment (MCI). Patients with MCI are at increased risk for Alzheimer's Disease (AD); we propose that increasing participation in activities will prevent cognitive decline and may delay the onset of Alzheimer's Disease (AD). We will test this hypothesis by conducting a clinical trial in which older AAs with MCI (aged 65 years and older) will be randomized to Behavior Activation (BA) (a behavioral intervention that increases participation in daily activities) or Supportive Therapy (ST) (a person-centered psychotherapy that involves active listening and offering support focusing on participants' problems and concerns). We hypothesize that BA-treated subjects will have fewer declines in cognitive and functional abilities, fewer depressive and neuropsychiatric symptoms, and better quality of life than ST-treated subjects at 24 months.

This study aims to evaluate the possible effect of dexamethasone on prevention of cognitive dysfunction in the postoperative period of elderly patients undergoing to surgery under general anesthesia.

Most primary care physicians do not screen older patients for cognitive impairment. Identification of cognitive impairment may result in earlier referral for diagnostic work-up and earlier treatment and better patient outcomes. The purpose of this study is to determine whether physicians who receive the results of a cognitive screen use this information in treatment plans and whether this results in better cognitive outcomes for the older patients.

Cognitive impairment is also a major risk factor for development of dementia later in life. Findings from our studies suggest that the carotenoids, lutein and zeaxanthin may be important in cognitive function in the elderly. The investigators have previously reported eggs to be a highly bioavailable source of lutein and zeaxanthin. Our study evaluates long-term egg intervention as a treatment strategy for age-related cognitive impairment which could possibly prevent the onset of dementia. The investigators have also shown that lutein supplementation significantly improved verbal fluency scores in healthy older women. Our studies have shown that egg interventions can significantly increase serum lutein concentrations in older adults. Based on the sum of our findings, the next logical step will be to investigate the ability of lutein and zeaxanthin contained in eggs to influence cognitive function in older adults. The investigators hypothesize that there will be a significant increase in cognitive function measures in older adults provided with meals containing 2 egg/day at the end of 6 months, while no significant improvements will be observed in older adults given daily meals containing egg substitute. The proposed study is designed as a randomized, placebo controlled trial that tests the effects of 6 month supplementation with 2 eggs/day on cognitive function in older adults. Secondary analyses will determine whether baseline MP density predicts relative effectiveness of the intervention on cognitive function. Secondary outcomes include plasma biomarkers of oxidative stress and inflammation.

Mild cognitive impairment (MCI) with ageing is thought in part to be related to reduced serum sex hormones which is well-recognized, especially in females, but poorly understood. International studies assessing hormone replacement therapy (HRT) to prevent/reduce MCI are ongoing. MCI leads to morbidity, reduced quality of life and substantial healthcare costs. The commonest therapeutically induced reduction in sex hormone level in men is treatment of prostate cancer (PCa). PCa is androgen dependent and androgen deprivation therapy (ADT) suppressing testosterone to castrate levels is key therapy for advanced disease. About one million men worldwide have received ADT for PCa, mostly using luteinising hormone releasing hormone agonists (LHRHa) although oral oestrogens were used in the past; eventually perhaps 4% of Caucasians may be castrated. MCI as a side effect of castration in men remains poorly researched. This study aims to demonstrate that pathological changes occur in the brains of a significant proportion of prostate cancer patients subjected to ADT that correlate with MCI symptoms. Highlighting the pathological changes of MCI should improve understanding and interventions for slowing/preventing MCI in PCa survivors. Brain scans employing positron emission tomography (PET) imaging technique will be used to detect the presence of pathological changes in the brain that relate to ADT induced MCI. MCI will be assessed by neuropsychological assessments (standard paper-based questionnaires and online) and its neural basis will be investigated using magnetic resonance imaging (MRI).

Move for your mind is a single blind, 3-arm randomized controlled clinical pilot trial. The study aims to test the effect of a weekly Dalcroze eurhythmics program (arm 1) and a home strength exercise program (arm 2) against control (no exercise) on the rate of falling, quality of life, gait performance and cognitive function. All groups receive vitamin D. In addition the study shall test the feasibility of the recruitment and the interventions in this target population. The study includes 60 seniors, age 65 and older, with mild cognitive impairment or mild dementia. Participants are recruited by the memory clinic of City Hospital Waid. During the 12 months follow-up, participants will have 3 clinical visits (baseline, 6 and 12 month). Despite major efforts the target population is very difficult to recruit and adherence to treatment is low. We therefore decided to stop recruitment and to use this trial as a pilot trial for future clinical trials of the same topic.

The primary objective is to examine the efficacy of 8-weeks of a locally developed brain-computer interface based system intervention for improving attention and memory in healthy elderly and those with age related cognitive decline. We hypothesize that elderly who have completed the training program will have significant improvement in their attention and memory compared to the controls, based on the Repeatable Battery for the Assessment of Neuropsychological Status.
