Filter by: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.
The purpose of this study is to evaluate three methods of performing home-based assessments in Alzheimer's Disease (AD) prevention trials. The initial in-person assessment will be done in the clinic or at home.
The primary objective of the study is to determine whether memantine is effective in slowing the rate of behavioral decline in frontotemporal dementia. The secondary objective of the study is to assess the safety and tolerability of long-term treatment with memantine in patients with frontotemporal dementia (FTD) or semantic dementia (SD). To determine whether memantine is effective in slowing the rate of cognitive decline in frontotemporal dementia. To evaluate whether memantine delays or decreases the emergence of parkinsonism in frontotemporal dementia. The tertiary objective of the study is to determine whether treatment with memantine affects changes in weight
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 purpose of this study is to examine the effects of testosterone (T) replacement on changes in thinking and memory, as well as mood in older men with mild cognitive impairment (MCI) and low T levels. The study will also examine whether taking testosterone has effects on biological markers related to Alzheimer's disease.
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.
The primary objective of the study is to investigate the effects of oral TRx0014 at three doses (30, 60 and 100 mg tid) compared with placebo on cognitive ability in patients with mild or moderate dementia of the Alzheimer type. Cognitive ability will be measured by the Alzheimer's Disease Assessment Scale - cognitive subscale (ADAS-cog). The primary evaluation will be made at 24 weeks.
The purpose of this study was to support the optimal use of rivastigmine patch in long-term treatment of Alzheimer's Disease in patients demonstrating functional and cognitive decline at the target maintenance dose of rivastigmine patch 10 cm^2.
It is well known that in the brain of the patients with Alzheimer's disease there is a glutamatergic hyperstimulation leading to neuronal death. Memantine is a low affinity antagonist of NMDA glutamate receptors. The use of this drug in the early phases of the disease could provide neuroprotective effects and delay of progression. The effects of memantine should be compared to those of donepezil, which is the most prescribed anticholinesterase drug.
The purpose of this study is to demonstrate that AZD3480 improves cognition in patients with mild or moderate Alzheimer's disease, to assess the safety and tolerability of ZAD3480 and to define the optimal dose(s) to be used in future trials.
