Active clinical trials for "Alzheimer Disease"

Memory loss and difficulties with thinking associated with Alzheimer's disease may be due to chronic release of a brain chemical called glutamate. Glutamate helps transmit messages between nerve cells through interaction with a certain type of receptor (N-methyl-D-aspartate, NMDA) on the cell. Neramexane is a new drug that blocks the effects of excessive glutamate at the receptor (NMDA receptor antagonist).

The purpose of this trial is to determine the effect of a new drug, SGS742, on memory and cognition in patients with mild to moderate Alzheimer's disease.

About 65% of patients with severe Alzheimer's Disease (AD) will have symptoms of agitation. There are drawbacks associated with the currently available therapeutic interventions for agitation associated with Alzheimer's Disease. In a recent trial, in the group of patients with moderate to severe AD treated with memantine, there were fewer incidences of agitation. It is hypothesized that memantine will be effective in reducing the symptoms of agitation associated with moderate to severe Alzheimer's Disease.

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

The goal of this research study is to evaluate the safety and efficacy of the rivastigmine transdermal patch in patients with probable Alzheimer's Disease.

ALADDIN is a research study to investigate the safety and effectiveness of leuprolide (a hormone drug) to improve the cognitive function and slow the progression of Alzheimer's disease (AD). In women leuprolide is commonly used to treat hormone related conditions such as endometriosis and uterine fibroids. The study will include treatment of women 65 years and older with mild to moderate Alzheimer's disease who reside in the community.

The purpose of this study is to examine the safety and effectiveness of two anti-oxidant treatment regimens in patients with mild to moderate Alzheimer's disease. The anti-oxidant treatments include vitamin E + C + alpha-lipoic acid, and Coenzyme Q (CoQ).

This study will compare four atypical antipsychotic medications in terms of the risk of specific side effects each of them presents in middle-aged and elderly individuals.

The purpose of this study is to evaluate the efficacy and safety of galantamine treatment in patients with mild cognitive impairment.

The purpose of this study is to evaluate the safety and efficacy of long-term administration of 23 milligram (mg) donepezil sustained release (SR) in participants with moderate to severe Alzheimer's disease. Participants who complete study E2020-G000-326 (NCT00478205) with no ongoing serious adverse events (SAEs) and no serious adverse drug reactions will be eligible to enter the open-label extension study.
