Filter by:We will use magnetic resonance imaging (MRI) to investigate tumor changes in women with breast cancer who are receiving anthracycline-based systemic chemotherapy. We will also use MRI and cognitive tests to study the possible effects of chemotherapy on the brains of these women. The results will be compared to a control group of normal healthy women. We will try to determine if MRI can be used to predict tumor response and cognitive changes related to the chemotherapy.
This research is being done to find out if daily use of the drug levetiracetam can improve memory function in individuals with memory problems like those associated with Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD).
The number of OEF/OIF veterans seeking care and rehabilitation services within the VA Health Care System is increasing rapidly. The cognitive effects of MTBI are clinically significant and can adversely affect a veteran's ability to reintegrate into civilian life, return to duty, succeed in competitive employment, or function independently. The primary product of the proposed study would be an empirically validated, manualized, cognitive rehabilitation intervention for OIF/OIF veterans with cognitive disorders. The group treatment modality has the virtue of efficiency and a manualized treatment approach would allow wide-ranging application throughout the VHA system. As such, the proposed study is likely to have a significant effect on the quality and effectiveness of rehabilitative services being offered to our returning soldiers with combat-related MTBI and cognitive impairment.
RATIONALE: Armodafinil may help relieve fatigue and improve quality of life in patients with cancer receiving radiation therapy to the brain. PURPOSE: This clinical trial is studying how well armodafinil works in treating fatigue caused by radiation therapy in patients with primary brain tumors.
This study will investigate the efficacy of the Flutemetamol (18F) Injection PET tracer in identifying abnormal (18F) flutemetamol uptake patterns which predict the conversion from aMCI to a b-amyloid associated clinically probable Alzheimer's disease.
The purpose of this study is to improve cognitive dysfunction following chemotherapy, the investigators investigated to see whether a cognitive training for memory and concentration skills can improve cognitive performance in patients following cancer treatment.
The main purpose of this study is to compare the effects on attention and memory functioning to participating in an aerobic and dance exercise called Zumba to educational program on exercise that encourages regular stretching and walking.
Schizophrenia affects approximately 1% of the population worldwide, and in about 80% of cases, it is a lifelong, disabling illness. It is a multi-dimensional disease that is associated with symptoms that have been characterized as positive, negative, and cognitive. CDS is a core feature of schizophrenia, and most individuals with schizophrenia exhibit cognitive impairment. Attention disorders, slow information processing, working memory disorders, and lack of flexibility for adaptive strategies are symptoms of cognitive impairment that have a devastating impact on the function, employment, and social status of patients with schizophrenia. Older typical neuroleptic medications (e.g., haloperidol, fluphenazine) do not improve cognition. In fact, haloperidol has been shown to induce cognitive impairment in schizophrenic patients. Novel atypical antipsychotics, such as risperidone, clozapine, and olanzapine, seem to produce gains in cognition. This improvement may reflect a diminution of extrapyramidal side effects of the typical high potency neuroleptics. Alternatively, it might reflect more effective symptom reduction by the novel antipsychotics, or direct cognitive enhancement through the effects of the newer agents on a variety of neurotransmitters, their receptors, and gene expression. Even when the newer antipsychotic medications improve cognition, they do not normalize it. Presently, there are no approved therapies for CDS. However, in schizophrenic patients, nicotine improves multiple cognitive domains, including working memory and attention. Furthermore, based on a strong body of evidence ranging from genetic mapping to clinical trials, the alpha7 NNR subtype has emerged as a primary therapeutic target relevant to CDS and other core symptoms of schizophrenia
The purpose of this study is to determine whether brain oxygenation measured by cerebral oximeter has an impact on neurocognitive dysfunction.
The general purpose of the present pathophysiological study is to investigate the relation between cognitive impairment observed after an acute coronary syndrome and the presence of cerebral anatomo-functional abnormalities. This study will improve the investigators' understanding of the disease and will help in early diagnosis and prevention of vascular dementia in this population.
