Active clinical trials for "Alzheimer Disease"

The effectiveness of reminiscence for dementia has been claimed as an effective tool, but scientific validation and systematic assessment of this method is needed. Materials and Methods: A randomized controlled trial (RCT) was conducted to search whether a reminiscence program is associated with improvement of quality of life of demented long term care residents. The trial had three arms: interventional, comparison and control. The reminiscence program was modeled within a life-story approach, while comparison group received informal counseling to control for changes in quality of life resulting from social contacts. The Social Engagement Scale (SES) and Self-rated Quality of Life Index (SRQoL) were the outcome measures. The results were examined at baseline (T0), twelve weeks (T1), and 6 months (T2) after intervention. The sample had 135 subjects [intervention group (N=45), comparison group (N=45) and control group (N=45)].

The purpose of this study is to determine whether VI-1121 is safe, well tolerated, and effective as a daily treatment for Alzheimer's disease that is worsening despite current treatment.

The state of the art with regard to the neurodegenerative dementias, especially for Alzheimer´s disease (AD), is that their progression is still irreversible causing cognitive, motor, and behavioral impairment. Although the current pharmacological treatments attenuate cognitive decline in some cases, the majority of treatments does not avoid the motor and functional changes caused by the progress of the disease. Although several studies show that exercise has a positive effect when it comes to the treatment of the disease, some methodological questions affect the application of the training protocols. The use of recognized intensity patterns like maximum oxygen uptake (VO2max) and maximum heart rate (HRmax) percentage to control the training of patients with dementia is still rare in the literature. Therefore, this seems to interfere on the definition of an ideal prescription. Following this line of reasoning, the purpose of the present study is to assess the effect of moderate aerobic exercise on cognition and functional abilities in AD patients. Design: Randomized controlled trial, double-blinded, with 16-week follow-up. Setting: Center for Alzheimer's disease in the Institute of Psychiatry of the Federal University of Rio de Janeiro. Participants: Elderly with Alzheimer disease. Interventions: The patients will be randomly assigned to an exercise group (EG) on a treadmill (30 minutes, twice a week and moderate intensity of 60% VO2max) and a control group (CG). Main outcome measures: Cognitive function will be assessed using CAMCOG, Trail Making Test A, Digit Span, Stroop Test, Rey auditory-verbal learning test and Clock Test, and functional capacity will be evaluated using Berg Balance Scale (BERG), Sit-to-Stand test (STS), functional reach test (FR), and the time to up and go test (TUGT).

The primary objective of the study is to compare the efficacy of aripiprazole with placebo in patients with psychosis associated with Alzheimer's dementia.

The purpose of this study is to investigate the effect of the rapidly acting intranasal insulin derivative (glulisine) on memory and cognition in 12 patients suffering from mild-moderate Alzheimer's Disease (AD) using a double-blind placebo-controlled single dose study. This study will further assess safety of insulin glulisine as well as the effects of this drug on olfaction.

The purpose of this study is to examine the effects of cilostazol augmentation in mild to moderate Alzheimer disease patients with subcortical white matter hyperintensities (WMHI) treated by donepezil. Dementia is the most disabling disease in the old age. The prevalence of dementia is 5-10% of the elders. AchEIs (donepezil, galantamine, rivastigmine) are used to treat mild to moderate dementia, but these drugs only relate to symptomatic improvement and the response rates are less than 30%. Cilostazol is a cyclic adenosine monophosphate phosphodiesterase 3 inhibitor (PDE3I) and used as antiplatelet agent in subcortical vascular disease (WMHI). And it upregulates phosphorylation of cyclic adenosine monophosphate-pathway response element binding protein (CREB) which plays a crucial role in memory enhancement and synaptic plasticity related to neurodegeneration prevention. The investigators will try cilostazol augmentation in dementia patients with WMHI receiving donepezil to see the addictive effects of cilostazol using cognitive tasks and PET imaging.

Resveratrol is derived from plants and is found in highest levels in red wine and the skin of red grapes. A recent study reported that monthly and weekly consumption of red wine is associated with a lower risk of dementia. There is compelling evidence that caloric restriction can improve overall health by activating a class of enzymes known as Sirtuins. Resveratrol is a substance found in some plants that directly activates sirtuins, mimicking the effects of caloric restriction and may affect regulatory pathways of diseases of aging, including Alzheimer's disease (AD). In this study, people with AD will be given either Resveratrol or placebo for 12 months to determine whether daily resveratrol therapy is beneficial in delaying or altering the deterioration of memory and daily functioning. Subjects age 50 and above with a diagnosis of probable AD may qualify for participation in this study. A small group of 15 participants will be asked to take part in a more detailed 24-hour Pharmacokinetic (PK) sub-study that will measure resveratrol levels over a 24 hour period.

Purpose of the study is to determine whether multiple dose administration of PF-04360365 is safe and well tolerated in patient with mild to moderate Alzheimer's disease.

This is a multiple dose study of NSA-789, the purpose of which is to assess the safety and tolerability in healthy subjects and subjects with Alzheimer's Disease

The purpose of this study was to evaluate the efficacy and safety of plasma exchange with 5% albumin in beta-amyloid peptide clearance in cerebrospinal fluid, and its effects in patients with mild-moderate Alzheimer's disease.
