View clinical trials related to Alzheimer's Disease.
Filter by:The primary objective of this trial is to assess the ability of Transcranial Magnetic Stimulation with H2 coil to prefrontal and parieto-temporal cortex to improve cognitive performance in patients with Alzheimer's disease which received drug treatment. This study is a single-center, double-blind 4 months duration trial.
The purpose of this study is to examine the cerebrospinal fluid (CSF) of patients with Alzheimer's disease for biomarkers of inflammation and their response to the antibiotics doxycycline and rifampin. The results of this preliminary analysis will be used in defining the direction of further research.
Alzheimer's disease (AD), is associated with behavioral disturbances in approximately 50% of AD patients in Beijing. Agitation, and aggression specifically, is considered the most serious noncognitive symptom experienced in patients with dementia. Memantine is a recognized treatment for Alzheimer's disease either alone or in combination with cholinesterase inhibitors. Its efficacy in vascular dementia is also established. Family members continue to play a central role in home care for the demented elderly in China. This proposal is to conduct a study in Beijing, China to investigate the efficacy and safety of Memantine in the treatment of agitation and aggression in AD patients. In addition, this proposal aims to explore the impact of memantine on caregiver burden of AD patients in Chinese culture.
This study aims to determine whether levodopa is effective in boosting learning and memory in healthy subjects and patients with dementia or Mild Cognitive Impairment. We also examine in healthy subjects using functional magnetic resonance imaging which brain regions mediate improved learning after levodopa administration.
The primary hypothesis is that quetiapine will improve sleep in persons with Alzheimer's Disease (AD), with higher doses producing greater total sleep time and sleep efficiency.
The white matter change of the Alzheimer's disease could be studied by diffusion tensor image and MR spectroscopy to see the microstructral and biochemical change.
Patients with different types of dementia will be recruited and evaluated in national hospital departments for their usual neurological follow-ups. A blood sample will be proposed in the field of this research project, and the biological material will be stored at the DNA and Cell Bank of Institut de Fédératif Recherche (IFR) of Neurosciences (Pitié-Salpêtrière Hospital, Paris). The clinical research network is already set up for Alzheimer's disease and frontotemporal dementias, which permits an evaluation according to a clinical standardized protocol. Among these disorders, a monogenic sub-group has been identified. In Alzheimer's disease, it is associated with the APP, PSEN1 and PSEN2 genes, which account only for 75% of the familial forms with early onset. In frontotemporal dementias, the tau gene mutations account only for 10% of the cases with an autosomal dominant inheritance. The identification of familial forms with a genetic inquiry in the relatives is essential for a greater knowledge of the molecular bases of forms not caused by the known genes, using linkage approaches and candidate gene analysis. The familial forms are also useful for identifying the modifier genes. In the multifactorial forms, the aim is to assemble a wide cohort of patients and controls matched for localizing and identifying susceptibility genetic factors. The strategies will use a candidate gene approach, and in the near future, studies of single nucleotide polymorphisms (SNPs) spread out in the whole genome. Meanwhile, similar approaches, particularly with candidate genes, could be used for identifying predictive factors of tolerance and response to the treatment. Finally, correlations will be performed with seric markers according to each kind of dementia. Specialized clinical teams in diagnosis and follow-up in dementias are assembled for this project, and in the study of neurological disorders of genetic origin.
The main goal of this project is to use imaging and biomarkers to identify cognitively normal elderly people who are at increased risk for developing mild cognitive impairment (MCI). MCI is the earliest clinically detectable evidence for brain changes due to Alzheimer's disease (AD). The second goal of this project is to describe the inter-relationships among anatomical biomarkers, cerebrospinal fluid biomarkers, and cognition measures in those elderly people who develop MCI.
