Filter by:RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known which regimen of bevacizumab given together with lomustine is most effective in treating patients with glioblastoma multiforme in first recurrence. PURPOSE: The primary objective of this study is to investigate whether the addition of bevacizumab to lomustine improves overall survival (OS) in patients with recurrent glioblastoma compared to treatment with lomustine alone.
Obesity has been associated with cognitive impairments, lower blood flow, metabolic activity and brain volume. Obesity in adulthood is a risk factor for Alzheimer's disease in the elderly. The mild cognitive impairment (MCI) is a condition that may precede dementia. We hypothesized that promotion of weight loss in obese people with MCI, through caloric restriction could lead to improvement in cognitive performance or reduction in the rate of decline and decreased risk of dementia. A sample of 80 patients aged ≥ 60 years, obese, with MCI, will be randomized to two groups that will be followed for 12 months. The control group will receive conventional medical care. The intervention group will receive nutritional counseling individually and in groups, aiming to promote weight loss through caloric restriction, and medical monitoring. Before and after intervention patients will be evaluated for anthropometry, body composition, physical performance, control of comorbidities, laboratory tests (glucose, insulin, lipid profile, leptin, adiponectin, interleukin 6, tumor necrosis factor alpha, CRP), Genotyping apolipoprotein E, neuropsychological battery, questionnaires about activities of daily living, physical activity and diet.
Mild Cognitive Impairment (MCI) is often an early manifestation of Alzheimer's disease (AD). The ability to identify MCI has led to hope that health prevention models might work in AD as they have in cancer and heart disease. Interventions which help sustain functioning in MCI may delay progression to a clinical AD diagnosis. To date, interventions aimed at maintaining functioning in MCI have been pharmacologic in nature. The efficacy of these medications in MCI is controversial, and those with MCI are also often interested in other activities they can do to manage their memory loss. When an individual is noted to have memory difficulties or MCI, a recommendation is often given for the patient to begin taking notes/using a calendar to help with memory or do cognitively stimulating activities. However, there is currently little instruction about how/what specific activities one should do and how effective they may be. The overall goal of this pilot project is to refine delivery of the Memory Support System (MSS)as a formal compensatory program for memory loss in MCI. Enrollment and retention data will be carefully investigated across 6 week and 10 day intervention groups. The investigators will compare participant adherence to the notebook training in the 6 week and 10 day versions of the intervention to the computer activity group. The investigators will also collect data on the clinical efficacy of the notebook and computer training to investigate if these interventions can sustain/improve functional level. Long term goals for this project also include delaying relocation for persons with MCI who may progress to dementia, thus not only improving the lives of these individuals, but also reducing health care expenditures. The investigators will recruit a total of 60 individuals with MCI and their 60 program partners across all three sites for this project. At least 16 of these pairs will be recruited at Emory University (maximum of 20 pairs/40 individuals anticipated). The investigators will randomly assign participants to the 6 week notebook or computer training or 10 day notebook or computer training. All participants will also receive patient education regarding MCI and cognitive health. Subsequent compliance with the MSS will be examined at 3 months, 6 months, and then annually following the intervention. Outcome measures will provide a detailed, multi-modal assessment of participants' functional level, overall cognitive functioning, mood, and self-efficacy, as well as caregiver burden and mood.
This study will evaluate the effects of low-intensity strengthening exercise on the brain (thinking and processing speed) for patients with early dementia, compared with normative older adults. Participants will engage in 3 months of exercise 3-5 times per week using a chair and small weights. It is hypothesized that there will be a significant improvement in brain function.
In this study, memantine will be tested in a new indication: in the treatment of subjective memory, concentration, or attention problems (subjective cognitive impairment) in the absence of dementia.
Cognitive impairment is seen in about half of patients with relapsing remitting MS. Our knowledge about long term development of cognitive performance under natalizumab therapy is limited. We want to demonstrate with this study that patients treated with ntz improve in neurocognitive tests over the long term.
This study is a cross sectional study of patients diagnosed with clinically isolated syndrome (CIS) and RRMS, who will undergo a series of tests to assess cognitive impairment, fatigue severity and depressive symptoms. Cognitive impairment will be assessed with Multiple Sclerosis Inventory Cognition (MUSIC) and symbol digit modalities test (SDMT), fatigue severity will be measured with the Fatigue Scale for Motor and Cognitive Functions (FSMC) and depressive symptoms with the Beck Depression Inventory (BDI). All tests mentioned above are validated for MS patients. In the second step we will use our large longitudinal database of serial MRI examinations from which a linear measurement of CCI will be retrospectively calculated.
This study will recruit a total of 150 evaluable subjects (30 cognitively normal volunteers, and 60 MCI(Mild cognitive impairment), and 60 AD(Alzheimer's disease), respectively) Each evaluable subject involved in this study must fulfill all the inclusion and exclusion criteria according the subject grouping. Safety measurement will be evaluated by medical history, vital signs, physical examinations, laboratory examinations and collecting of adverse events. This study is expected to be completed in a period of 3 years.
The trial was designed to test the hypothesis that early treatment with nimodipine has a positive effect on cognition impairment after acute ischemic stroke.
Many persons with Multiple Sclerosis ( MS) have problems with memory and thinking.Exercise has been shown to improve memory and thinking in persons with diseases such as Alzheimer's. This study will investigate whether a program of aerobic exercise can improve memory and thinking in persons with MS
