Filter by:The purpose of this study is to determine whether scopolamine-induced cognitive impairment is attenuated by the administration of roflumilast in combination with donepezil.
The purpose of this study is to determine whether by measuring changes in the thickness of the retinal nerve fibre layer (the photosensitive layer at the back of the eye) you could predict if someone would develop Alzheimer's disease in the future. The measurement is made by OCT (ocular coherence tomography), a noninvasive and relatively inexpensive test that uses light waves to scan the back of the eye.
The investigators are going to test if it is possible to detect early dementia with the digital game "memory". The investigators are going to test 15 healthy people and 15 patients with early dementia. The test consists of playing the game "memory" several times. While playing, several parameters are stored. The investigators are going to test if any correlation can be found between these parameters and the cognitive state of the person as tested by the Mini-Mental status examination.
A thorough QT study of AZD3293
There are few pharmacological treatments available for Alzheimer's disease, including drugs called cholinesterase inhibitors: donepezil, galantamine, and rivastigmine. In research trials, cholinesterase inhibitors have been shown to improve memory and problem behaviours in people with mild to moderate Alzheimer's disease. However, these benefits may not extend to the real-world when taking into account nursing home and health care costs. There is less information on the use of cholinesterase inhibitors in people with severe Alzheimer's disease. In Canada, only donepezil is recommended for the treatment of severe Alzheimer's disease. However, there is no information on whether the benefits that donepezil provides to people with severe Alzheimer's disease are sustained over the long term. Moreover, while the tolerability of cholinesterase inhibitors is generally acceptable, their use is not completely harmless. Common side effects include nausea, diarrhea, insomnia, vomiting, muscle cramping, fatigue and loss of appetite. In Ontario, cholinesterase inhibitor users tend to remain on these medications for two years or more and often until death. The current cholinesterase inhibitor guidelines provide details on what medication should be used, when it should be started and how it should be monitored, but there is less clarity on when it is safe and appropriate to stop treatment. The cessation of cholinesterase inhibitors in patients no longer appearing to display any clear benefits may help to lower the risk of unpleasant side effects, lower the use of multiple medications, and reduce the costs of caring for individuals with Alzheimer's disease. However, the cessation of cholinesterase inhibitor therapy may run the risk of deterioration in memory, worsening or development of behavioural symptoms and the placement of additional demands on professional and unpaid caregivers. There is a clear need for guidelines when to stop cholinesterase inhibitor treatment, especially for patients in whom the benefits of not be on the medication will outweigh the risks. The purpose of this study is to address this issue by collecting data which may be helpful in predicting which types of patients may benefit from stopping cholinesterase inhibitor treatment. Understanding when, and for whom, it is appropriate to stop cholinesterase inhibitor treatment will influence the field of pharmacology in the treatment of Alzheimer's disease.
Alzheimer Disease (AD) is a progressive brain disease generally known as senile dementia. Our proposed study will establish safety and pharmacokinetics of Meganatural-AZ GSPE in AD subjects. As secondary measures, we will also provide the essential human data to guide the design of future studies to test the efficacy of GSPE in mitigating cognitive deterioration in AD patients.
This follow-up study continues to observe patients who have completed the phase 1 trial of AADvac1, for another 18 months. Long-term safety and behavior of the immune response to AADvac1 over time are the main points of interest. AADvac1 is a vaccine directed against pathologically modified Alzheimer tau protein that is the main constituent of neurofibrillary tangles (NFTs), and is intended to be a disease-modifying treatment for Alzheimer's disease, i.e. to halt its progress. As this study is a Phase I study focused on tolerability and safety, efficacy will be assessed in an exploratory manner.
This study is designed to validate the Japanese electronic florbetapir (18F) interpretation training program intended for post-approval implementation in Japan.
The Alzheimer's Prevention Registry (www.endALZnow.org) will collect contact and demographic information on individuals. The objective is to provide information the latest news and advances in Alzheimer's prevention research, and to inform enrollees about research studies in their community. Enrolled individuals will receive regular email communications. As research studies become available, individuals will be notified via email with information as to how proceed should they be interested. Registry enrollees are under no obligation to participate in a research study. Study opportunities may include surveys, healthy lifestyle interventions (e.g., diet, exercise), memory & thinking tests, brain scans, and investigational drug trials.

Alzheimer's disease (AD) is the most common cause of dementia and currently has no disease modifying treatments or simple accurate diagnostic tests. The goal of this project is to study how amyloid-beta (a protein thought to cause AD) is made, transported and cleared in the human body. Better understanding of these processes may lead to improved understanding of AD, earlier diagnosis and a way to evaluate treatment.
