Active clinical trials for "Cognition Disorders"

In the study at hand, six patients with light to moderate Alzheimer's disease will be enrolled and implanted with bilateral electrodes in the nucleus basalis Meynert.

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

The purpose of this study is to determine the safety and efficacy of C105 in treating the cognitive deficits that can occur due to multiple sclerosis.

Background: Different anaesthetic agents have been shown to have different protective effects upon heart, brain and renal function under ischaemic conditions (oxygen starvation). Cardiopulmonary bypass takes over the work of the heart and the lungs during heart surgery, but oxygenation of vital organs such as the brain and heart may not be perfect, and can produce brain or heart damage as a consequence. Propofol and desflurane are commonly used anaesthetic agents, and there has been recent research to suggest that anaesthetic agents may provide some protection during periods where inadequate oxygenation occurs, with the potential to reduce the degree of organ damage. Both types of anaesthetics are used for cardiac surgery with anaesthetists choosing between them largely on the basis of personal preference. Aim: To determine whether the use of either propofol or desflurane as the primary anaesthetic agent, can lead to differences in postoperative brain function, total morbidity or cost, following coronary artery surgery with cardiopulmonary bypass. Methods: Patients will be recruited by professional research staff and will be randomised into one of two groups (90 in each group). They will receive a standardized technique for anaesthesia, cardiopulmonary bypass and postoperative ICU treatment. The only difference between the 2 groups will be as to which anaesthetic agent they receive during the surgical period, desflurane or propofol. Measurements will involve i) brain function testing before and 3 months after surgery ( a set of 10 verbal or manual tests), ii) incidence of delirium in the immediate postoperative period (a survey form), iii) incidence of total postoperative morbidity and iv) cost of hospital stay. Data collection will be by anaesthesia and research staff and a neuropsychologist will employed for performing the brain function testing. Anticipated timeline: Initial recruitment completed by 15-18 months following trial commencement. Follow up completed 3 month after the last enrolment. Data validation, statistical analysis and manuscript preparation completed by 24 months.

This study will determine the effectiveness of a peer support system in increasing physical activity and effecting health behavior change in people with serious mental illnesses.

A decrease in mental function often occurs in patients with HIV. Antiretroviral (ARV) drugs are used to treat this but are not entirely effective. Some other therapy could play a role. The drug selegiline in its pill form is used to treat Parkinson's disease, a serious brain disorder. It is believed this drug might protect the brain and repair some damage. This study will use this drug in a "patch" form, which has not been approved by the Food and Drug Administration (FDA), to see if it helps with decreased mental function in patients with HIV. The purpose of this study is to evaluate the use of selegiline transdermal system (STS) in the treatment of decreased mental function in patients with HIV.

To assess the tolerability and safety of OPC-14117. To evaluate effects of OPC-14117 on cognitive function, quality of life, and activities of daily living.

In this proposal, we will examine processing speed training (PST) as a potential intervention to reduce the risk of developing long-term cognitive impairment after a delirium episode.

Based on research showing that cognitive-motor training programs help improve cognition in older adults with mild cognitive impairment, this program uses an interactive system to combine cognitive training with exercise. The interactive system consists of wearable sensors and has the advantage of cognitive training without space constraints, and the cognitive training program consists of a total of five developed cognitive training games. The program is expected to improve the cognitive abilities of the elderly and improve their physical abilities.

Multiple studies in the spinal cord injury (SCI) population have documented deficits in learning and memory (LM) and processing speed (PS) that adversely impact daily life and the ability to benefit from rehabilitation. The investigators have previously attributed the cognitive deficits demonstrated in the SCI population to low blood pressure (BP) and cerebral blood flow (CBF) and are currently conducting a study to determine the effect of a 30-day elevation in BP (using midodrine hydrochloride - an alpha agonist) on CBF and cognitive performance compared to placebo in hypotensive individuals with SCI. In addition, the investigators believe that cognitive behavior therapy (CBT) may improve cognition independent of changes in BP and CBF in individuals with SCI. The current randomized clinical trial (RCT) will examine the efficacy of 2 treatment protocols shown to be effective in improving cognitive performance in other neurologically impaired populations for use in persons with SCI demonstrating (1) LM impairment and/or (2) PS impairment on objective measures of cognitive functioning during a complete Neuropsychological assessment. Two methods of outcome assessment will be used to examine treatment impact: (1) a traditional Neuropsychological assessment (NP) and (2) an assessment of global functioning (AGF) composed of broader outcome measures that examine the impact of the treatment on everyday life activities. In this way, the investigators will be able to objectively evaluate the presence or absence of changes in memory performance through a NP assessment, while also evaluating the impact of this treatment protocol on everyday life through the AGF. While most studies evaluating the efficacy of cognitive retraining usually employ a pre- and post-training evaluation, such evaluations have been criticized for their lack of ecological validity (i.e., real world generalizability). The present design allows the assessment of the efficacy of these treatment techniques within an SCI population using traditional measures, as well as the assessment of the impact that treatment has on everyday life. The investigators will additionally evaluate the long-term efficacy by including a 6-month post-treatment follow-up. Few studies examine long-term effects, but given the time, labor and expense involved, it is critical to demonstrate long-term efficacy.
