Filter by:The purpose of this project is to test whether an online cognitive rehabilitation program or online thinking exercises helps improve memory and thinking in elderly patients who survive a severe infection.
This study aims to see whether intranasal insulin is an effective treatment for problems with memory, concentration, slowed thinking, or any other cognitive function in people living with HIV/AIDS. This group of signs and symptoms are called 'HIV-associated neurocognitive disorders' or HAND. HAND can affect people living with HIV/AIDS even when they receive potent anti-HIV treatments. Treatment of HAND by specific medication or other means is not yet available. Intranasal insulin treatment has virtually no side-effects, and has already been tested in people with Alzheimer's disease, where it showed beneficial effects on memory, mood and quality of life
Behavioral interventions currently provide the most useful approach to addressing the behavioral and social needs of those with Mild Cognitive Impairment (MCI) due to Alzheimer's or other diseases. This randomized, multisite, 3-arm study will investigate the impact of computerized brain fitness vs yoga vs an active control group (wellness education) on changes in cognitive function, daily functioning and quality of life in persons with Mild Cognitive Impairment (MCI) and their partner. In addition, in vivo neuroimaging measures of plasticity during the pre- and post-intervention periods will be measured and compared between the three different treatment groups. These neuroimaging measures of plasticity will be investigated in their relationship to the cognitive outcomes within each group.
Infection with HIV (the virus that causes AIDS) can lead to problems with brain function, such as memory, concentration, judgment, and the speed or control of hands and legs. Neurologists have called this condition HIV-associated neurocognitive disorder (HAND). This research is being done to see if insulin taken through the nose as a spray (intranasal insulin) can help people with HIV who are having problems with memory and brain function, or HAND. Participants will be given either insulin or placebo. A placebo is an inactive substance that looks like the study drug, but does not contain study drug. For this research study, the placebo will be a clear, saline-based liquid spray that looks like the insulin spray but has no insulin. Participants will not be told whether they receive insulin or placebo during the study. All participants will take the intranasal spray twice a day, about 30 minutes after a meal. Participants will use a specialized intranasal drug administration device. The total daily dose of insulin is 40 IU split between 20 IU in the morning and 20 IU in the evening. Participants will take the intranasal spray for 24 weeks. The researchers will record symptoms and side effects during the study. Procedures include neurocognitive testing of memory and brain function, two optional lumbar punctures ("spinal taps"), two MRI brain scans, monthly blood draws, and clinical assessments.
Neurocognitive Disorder (NCD) affects over 116'000 people in Switzerland and is frequently unrecognized and underdiagnosed. Because missed and delayed diagnosis are associated with an increased burden of disease health Service Research has prompted a discussion about diagnostic guidelines and screening programs. Some argue that screening for NCD in primary care is the optimal strategy to increase recognition rates; others consider test protocols implemented into hospital admission assessments as more justified. There is no distinct recommendation due to a lack of empirical data on the benefits and harms of cognitive testing yet. This trial strives to fill this gap and provide information about the benefits, harms and the economic case of routine cognitive testing for neurocognitive disorder in high risk elective inpatients, in Switzerland. The investigators hypothesize that, cognitive tested patients, compared with patients not cognitive tested, will have higher health-related quality of life at 12months; and lower medical health care costs at 18months.
The purpose of this study is to develop pilot data on the potential efficacy of computer-based cognitive training or the combination of computer-based cognitive training with transcranial direct current stimulation (tDCS) in improving cognitive function in persons with HIV-related mild neurocognitive disorder (MND).
The study is a substudy of the Enigma2 trial (NCT00430989) which aims at investigating the effectiveness and safety of nitrous oxide (N2O) in anaesthesia.The substudy focus is on postoperative cognitive disorders. Substudy Hypothesis: In patients undergoing anaesthesia for major surgery, administration of N2O will reduce postoperative cognitive disorders when compared with otherwise identically managed surgical patients not receiving N2O as a component of their anaesthesia.
Background: - Human immunodeficiency virus (HIV) infection appears to cause problems with blood vessel function. These problems may add to some thinking and mood disorders found in people with HIV infection. Researchers want to evaluate HIV infected patients to see if blood vessel function contributes to thinking and mood disorders, such as early dementia and depression. To do so, they will compare study results between people with and people without HIV infection. Objectives: - To compare the thickness of blood vessel walls between people with and without HIV infection. - To study the relationship between blood vessel thickness and thinking and mood disorders. Eligibility: - Individuals between 25 and 55 years of age who have HIV infection. - Healthy individuals between 25 and 55 years of age. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. - Participants will have imaging studies of the brain and major blood vessels in the head and neck. - Participants will also have neuropsychological testing. These tests will look at memory, learning and thinking ability, attention, and mood. - Participants will have the option of coming back for repeat blood tests every six months and repeat imaging studies and neuropsychological tests every year, over 1- 4 years period.
Background: - Some people with human immunodeficiency virus (HIV) develop problems with thinking and concentration when the virus affects the brain. This is known as mild neurocognitive disorder (MND). Research has shown that some HIV medications do not get through the blood brain barrier very well. P-glycoprotein (P-gp) is a brain protein that is part of the blood brain barrier. Differences in the activity of P-gp may help explain why some people with HIV develop MND. It is also possible that MND is partly due to inflammation in the brain. Researchers want to study P-gp and its effect on MND and HIV infection. Objectives: - To study P-gp and brain inflammation related to HIV infection. Eligibility: - Individuals between 18 and 60 years of age who have HIV and either do or do not have MND. - Healthy volunteers between 18 and 60 years of age. Design: - Participants will be screened with a medical history and physical exam. Blood and urine samples will be collected. - Participants will have one outpatient visit and one 3-day inpatient stay. - At the outpatient visit, participants will provide blood samples and have a lumbar puncture (spinal tap). The spinal tap will collect cerebrospinal fluid for study. - At the inpatient visit, participants will have two positron emission tomography (PET) scans of the brain. These scans will study brain activity and possible inflammation. One scan will involve a study drug called tariquidar, which blocks the activity of P-gp. A second lumbar puncture will be done before the first PET scan. Blood and urine samples will be collected daily.
