Active clinical trials for "Cognitive Dysfunction"

The purpose of the study is to evaluate the safety and tolerability of ascending oral doses of CHF 5074 after prolonged administration to patients with mild cognitive impairment.

Dementia is serious problem and around 700 000 people are affected in the UK alone. Currently there is no cure however early diagnosis and effective treatment offers hope for reducing the impact. Dementia sufferers require care due to physical disability, cognitive deficits, social isolation and emotional symptoms (depression). Delaying the onset of dementia will improve quality of life for patients and reduce the cost of residential care (£42 000 per person per year). People with mild cognitive impairment (MCI) are at high risk of developing dementia. They have impaired cognitive abilities, such as memory, but still manage their everyday activities. Studies show that 8 out of 10 people with MCI will have developed dementia 6 years after diagnosis. Regular physical activities and performing a variety of cognitive activities reduce the risk of dementia and improves abilities and quality of life in healthy people. Therefore a combination of these activities may reduce the risk of developing dementia in MCI. The investigators want to see if they can develop a program which combines these activities in a fun and social way that gets people active and keeps them active. The aims are to improve fitness, cognition and quality of life. The investigators plan to use computers and the internet to help with the activities and to make them available to people who are isolated. Physical activity will involve walking from home, cognitive activities will be computer based games and puzzles and socialising will involve regular varied group-based activities. Participants (128) will be recruited from the UCL Derwent Memory Clinic and will complete a 26 week program. They will then be followed up yearly to monitor their progress. The main outcome of the study is engagement in the activities. The investigators will also measure fitness, cognition, quality of life and conversion to dementia.

This is a safety and efficacy study evaluating a experimental treatment for cognitive deficits in adults with schizophrenia.

The primary aim of this study is to assess whether daily dosing with medium chain triglycerides in subjects with mild cognitive impairment (MCI) will improve cognitive performance.

This is an efficacy study evaluating a experimental treatment for cognitive deficits in adults with schizophrenia.

The majority of school-age children with sickle cell disease (SCD) experience neurocognitive deficits, even in the absence of stroke. In particular, deficits in attention and working memory have emerged as two of the most common neurocognitive sequelae of SCD. Thus, the goal of the present proposal is to address feasibility and compliance of a novel computerized cognitive training program, Cogmed. Pilot data will also be collected to establish preliminary efficacy. Twenty-four children meeting initial age and diagnostic criteria will be identified and approached about participation by their attending physician during regularly-scheduled SCD clinic visits. Baseline assessments will include a brief measure of intellectual functioning, a brief cognitive testing battery evaluating processing speed and working memory, in addition to questionnaires regarding behavior and quality of life. Children will then be randomized to the computerized CT program Cogmed (n=12) or a waitlist control (n=12). Participants enrolled in the computerized CT program will be asked to complete 25-sessions of Cogmed over a five to eight week period (3 to 5 sessions per week). Following completion of the program, children and their parents will be asked to return to clinic for a follow-up visit. After a five to eight-week waiting period, children in the waitlist condition will also be asked to return to clinic for a second visit. Following this assessment, participants initially enrolled in the waitlist will be offered an opportunity to participant in the intervention. If interested, they will follow the same intervention protocol described above. These children will return to clinic for a third visit following completion of the intervention. Compliance rate and its confidence interval will be calculated for the overall study population. A t-test for binomial proportion with continuity correction will be used to examine whether the compliance rate is lower than the target. Participants' change in criterion outcomes will be evaluated (i.e., those neurocognitive measures such as attention, executive functioning and working memory, that are most closely related to the trained tasks).

The study will investigate the viability of two cognitive rehabilitation strategies to improve functional outcomes for people with schizophrenia. Many people with schizophrenia experience impairments in cognitive function which limit their abilities. These impairments have been shown to precede the onset of illness and represent a vulnerability factor which is exacerbated by emerging psychotic symptoms. These impairments affect a range of functional domains including symptom severity, work function, symptom management, treatment, and overall quality of life. Recognizing the link between cognitive impairment and function, a few clinicals and researchers have attempted to remediate cognitive impairments by providing cognitive retraining programs similar to those used in traumatic brain injured patients or adaptive skills training. Cognitive retraining involves repetitive exercises to increase elemental cognitive functions including memory, attention, psychomotor speed, planning, and cognitive flexibility. Adaptive skill training involves didactic group exercises in social skills, activities of daily living, and symptom management. Each approach has demonstrated some rehabilitation benefits. This study will investigate the effectiveness of a combination of these two approaches on outcomes in schizophrenia.

This study is designed to investigate the efficacy and safety of rivastigmine compared with placebo in patients with traumatic brain injury and cognitive impairment.

Glutamate is fundamentally involved in learning and memory. Memory loss associated with mild cognitive impairment may be due to loss of glutamate receptors in the aging brain. There is evidence CX516 enhances brain activity by specifically targeting remaining glutamate receptors in the affected portions of the brain. This study will test the safety and efficacy of CX516 in the symptomatic treatment of participants with mild cognitive impairment.

The purpose of this study is to: To examine wether adjunctive atomoxetine is more effective thank placebo for neuropsychological measures of reaction time, motor speed, psychomotor speed, sustained attention, learning and memory, working memory, and executive functioning. To determine the effect size of atomoxetine on these neuropsychological measures for follow-up studies. To determine if atomoxetine has short-term benefits for improving weight gain and other metabolic abnormalities associated with antipsychotics.
