Active clinical trials for "Alzheimer Disease"

This study used two doses of rivastigmine transdermal patch (5 cm^2, 10 cm^2) to establish the feasibility of 2 switch schedules (with transdermal patch one-step dose titration or without dose titration) from rivastigmine capsules (3 mg bid (bis in die, twice a day), 4,5 mg bid, 6 mg bid) to rivastigmine transdermal patch and to assess safety, tolerability, convenience, and caregivers preferences of rivastigmine transdermal patch versus capsules.

A recent meta-analysis that included over 29.000 individuals found that the odds ratio (OR) of individuals with high brain reserve compared to low was 0.54 (p < 0.0001), a risk decrease of 46%. Among the factors that influence cognitive reserve, mentally stimulating activities was the most robust factor after controlling for education, age, occupation and other potential confounds. The brain reserve effect was sustained over a median longitudinal follow-up of 7 years. It would be interesting to detect whether a complex cognitive training could show similar effects on the cognitive abilities of patients with mild Alzheimer's disease (AD) and mild cognitive impairment (MCI) as it has been reported in previous studies based on mentally stimulating activities analysis. The hypothesis is that a complex cognitive training alters the neural networks in both subject groups and this alteration is associated with improvement or stabilization of cognitive and non-cognitive function. The investigator will perform a complex cognitive training program. Twenty patients with mild AD and twenty four patients with MCI will be recruited in this study. The patients will be randomised in control- and treatment groups.Additionally indirect effects on non-cognitive functions will be evaluated in caregivers of the patients. The investigators expect that the cognitive and non-cognitive abilities will be changed during the cognitive training. The investigators also expect differences between treatment and control groups.

The study will evaluate the safety and effectiveness of bapineuzumab for the treatment of mild to moderate Alzheimer disease. Subjects will be in the study for six months and will receive subcutaneous injections once per week.

This study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of R1450 in patients with mild to moderate Alzheimer Disease. Patients will be randomized to receive either R1450 or placebo by intravenous infusion for a total of 7 doses. The starting dose will be escalated in subsequent cohorts of patients in an adaptive manner, after a satisfactory assessment of safety, tolerability and pharmacokinetics of the previous dose. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

To assess the dynamic uptake and washout of 123-I CLINDE, a potential imaging biomarker for inflammatory changes in brain, using single photon emission computed tomography (SPECT) in similarly aged healthy controls and subjects with Alzheimer (AD) or Parkinson disease (PD). To perform blood metabolite characterization of 123-I CLINDE in healthy and subjects with AD or PD to determine the nature of metabolites in assessment of 123-I CLINDE as a single photon computed tomography (SPECT) brain imaging agent. Evaluate the test/retest reproducibility of 123-I CLINDE, and SPECT in AD and PD subjects and healthy controls

The efficacy of 8 mg of copper daily regarding cognitive function, content of beta amyloid protein in the CSF and volumetric changes in the brain will be examined in a first double-blind, placebo-controlled human clinical trial conducted in 70 patients with mild Alzheimer´s dementia.

This preliminary study is aimed to investigate whether it is feasible to conduct a study to use fish oil compared to the placebo(olive oil) in people with cognitive impairment. We will also explore whether fish oil has better efficacy in some clinical aspects in people with cognitive impairment during 24 weeks intervention. The major clinical outcome will be: general clinical impression cognitive function

The purpose of this study is to determine the safety and tolerability of BMS-708163 in patients with mild to moderate Alzheimer's disease over a treatment period of 12-weeks and the course of any potential effects during a 12-week wash-out period

The aim of the study is to evaluate the effect of EGb761®, in comparison to placebo, on cerebral glucose metabolism, in three groups of elderly patients: newly diagnosed mild Alzheimer's disease (AD), memory complaint patients with cognitive impairment (MC) and memory complaint patients cognitively normal (CNE). The first phase includes four weeks treatment with EGb761® for all groups, with change in brain glucose metabolism at month 1 using 18 FDG-PET, as primary endpoint which will be followed by an open 17 months follow-up (FU) period with EGb761® treatment in MC and CNE patients.

The purpose of this study is to evaluate the efficacy and safety of two fixed doses (16mg/day and 24mg/day) of galantamine (a drug for treating dementia) versus placebo for the treatment of patients with Alzheimer's disease.
