Active clinical trials for "Alzheimer Disease"

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.

To characterize the comorbidities and medications of patients treated with donepezil in a routine clinical practice and to verify the therapeutic response of these patients.

A Double-blind, Randomized, Placebo Controlled Study to Evaluate the Efficacy and Safety of DCB-AD1 in Patients with Mild to Moderate Alzheimer's Disease. Because of the limitation of the sample size we could expect but a positive trend of the efficacy unless the effect size of DCB-AD1 is larger than 0.63. This information will provide us clue if further clinical investigation such as a phase III study should be carried out in an even larger scale. We also should be able to obtain valuable experience on the adverse effect of prolonged (24-week) use of Fo-ti.

The purpose of this study is to investigate transcranial direct current stimulation (tDCS) as a cognitive enhancer for patients with Alzheimer disease. Transcranial direct current stimulation (tDCS) is a neuromodulation technique, that are applied to the brain by using two electrodes. These electrodes are placed on the scalp. The current is low intensity, usually 1-2 milliampere. tDCS may affect cognitive functions by increasing cortical excitability. tDCS is regarded as a safe treatment approach. In the present study, participants will undergo six stimulations. The effect of all stimulations swill be measured with neuropsychological testing before the first (pre) and after the sixth tDCS stimulation (post).

This study is a prospective, single arm, non-randomized, interventional study to evaluate the safety and effectiveness of Omental transposition (OT) in subjects with early stage AD. Within-subjects (repeated-measures) design will be utilized to compare follow-up outcomes to baseline. The following assessments will be performed at baseline, then at 1, 3, 6, 12, and 24 months following surgery: Montreal Cognitive Assessment (MoCA) Alzheimer's Disease Assessment Scale-Cognition (ADAS-Cog) General Practitioner Assessment of Cognition (GPCOG) Eight-item Informant Interview to Differentiate Aging and Dementia (AD8) Subjects who have early stage AD confirmed by a neuropsychological test (MoCA) and who are healthy enough to undergo surgery. The experimental procedure to be performed is omental transposition (OT) surgery. It will be performed as a laparoscopic or open procedure for omental lengthening and an open procedure for brain access, with a general surgeon performing the omental lengthening/tunneling and a neurosurgeon performing brain access/brain biopsy/omental placement on brain. Up to twenty-five (25) subjects, with the first 5 subjects being part of a learning curve group and the next 20 subjects being part of the experimental group. The duration of each subject's participation will be approximately 25 months from screening through the 24 month follow-up visit.

This study aims to proof the efficacy of a cognitive rehabilitation program for patients with mild dementia in Alzheimers Disease with respect to activities of daily living.

Difference in nutritional status between patients with mild and moderate Alzheimer's Disease (AD) and cognitively intact healthy people in an Asian population

Dementia with Lewy body (DLB) is the second most common neurodegenerative dementia in autopsy series. However, DLB represents a small proportion of the clinical diagnoses in epidemiology registries. Indeed Alzheimer disease (AD) and DLB are often concomitant, they share many symptoms and only a small weight is given to non-motor symptoms in DLB diagnosis. DLB is at the end of a pathological spectrum overlapping with AD, explaining the poor diagnostic value of both diagnostic criteria. To date there is still a need for a tool able to discriminate patients with pure DLB from those expressing common signs with both AD and DLB and those with pure AD. The purpose of this study is to validate a semi quantitative scale designed to reflect the Lewy Bodies burden in patients with mild to moderate cognitive decline. The investigators hypothesized that the score obtained may differentiate between AD, DLB and patients fulfilling clinical criteria for both DLB an AD. This score could also be correlated with dopaminergic depletion assessed with [18F]fluorodopa PET/computed tomography and/or with potential biomarkers of ADD measured in cerebrospinal fluid. This clinical validation is a preliminary work preceding further studies correlating the LeSCoD score with functional imaging features, prognosis and therapeutic response. Thus, the expected outcomes involve an improvement in demented patients' care, as well as a better patient selection for further therapeutic studies

A total of 200 home dwelling participants, who fulfil the inclusion criteria, Alzheimer's disease, will be recruited from three hospitals in Norway. The intervention is based on a standardized manual, and consists of 11 weekly one-hour sessions, which are organized into six thematic modules. The content of each session is specified by a treatment manual, which additionally consists of worksheets, suggestions for homework in between sessions and letters to the caregivers (the German manual: Werheid & Thöne-Otto, 2010; the Norwegian manual: Ulstein, Gordner & Tonga, not published). The treatment will be conducted by experienced health staff (nurses, psychologist, doctors) with formal training in Cognitive Behavioural Therapy, and knowledge about Alzheimer's Disease. Furthermore, the health staff will be familiarised with the manual before study inception, participate in a two-day training seminar and will regularly be supervised. The control condition will be offered treatment as usual at the participating the memory clinics. The hypothesis is that the participants in the intervention group will report less depression and increased self efficacy as compared with the control group. We conducted a pilot study with 10 patients, 5 in each group, from March to June 2013 to examine the feasibility of the study protocol and do want to include these patients in the study population.

The primary goal of this study is to evaluate the efficacy and safety of the DBS to the fornix/NbM among patients who are diagnosed as AD according to a series of evaluations including cerebrospinal fluid (CSF) biomarkers and molecular imaging examinations; The secondary goal is to compare the efficacy among the two treatment groups of different targets.
