Filter by:This study evaluated the safety and efficacy of 10 cm^2 rivastigmine patch in patients with Alzheimer Disease (MMSE 10-26). The primary objective was the percentage of patients who stayed on the target size of 10 cm^2 for at least 8 weeks. This proportion was then compared to historical data of the percentage of patients who could reach a rivastigmine capsule target dose of 12 mg and stay on it at least 8 weeks.
The goal is to determine how 6-week stress reduction techniques may decrease stress in primary caregivers of people with Alzheimer's disease. The 3 intervention programs are meditation, education, and respite care. There will be approximately 108 subjects over 3 years. Subjects will have a screening session over the phone to see if they are eligible (50-85 years old, spending at least 12 hours per week caring for a close relative with Alzheimer's disease, willing to be in any of the 3 groups, and without any very serious medical problem). The subjects will have 3 testing sessions, 1 before classes/respite and 2 after classes are over, each lasting about 3 hours. The classes are taught in a one-on-one setting, and they are 50 minutes per week for 6 weeks. Respite care is provided for the person with Alzheimer's disease in all the groups. Measurements include people's ratings of stress, psychological testing, and biological measurements of stress, including the following: saliva, blood, and urine collection; waist-to-hip ratio; weight; blood pressure; heart rate; respiration; reaction time task; voice recordings; electrocardiogram; electroencephalogram; and electro dermal activity.
SB-742457 is a 5HT6 receptor antagonist that is in development for the symptomatic treatment of mild to moderate Alzheimer's disease . To date, all clinical trials have been conducted using a capsule formulation of SB-742457. However, it is intended to conduct all futures studies with a tablet formulation. The aim of this study is to assess the pharmacokinetic profile of SB-742457 and its major metabolites following single doses of both the capsule and tablet formulations.
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.
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 study will include a preliminary pharmacokinetics (PK) / safety / tolerability evaluation in healthy elderly subjects followed by the Receptor Occupancy (RO) evaluations in healthy elderly subjects and in Alzheimer's Disease (AD) subjects.
The purpose of the study is to determine the efficacy of methylphenidate over placebo in treating apathy in patients with Alzheimer's dementia. Apathy is one of the earliest and most profound disturbances that occur in Alzheimer's dementia (AD). Hypotheses: 1. Methylphenidate (MPH) will improve apathy significantly more than placebo in AD. 2. Successful treatment of apathy will improve Instrumental Activities of Daily Living (IADLs), and caregiver burden.
