Active clinical trials for "Alzheimer Disease"

This study examines the sensitivity of functional MRI to detect brain changes caused by donepezil HCL (a cholinesterase inhibitor) in healthy older adults at genetic risk for Alzheimer's Disease.

The purpose of the study is for investigation and collection of Aricept safety information with a dose increase on Alzheimer's disease patients.

To investigate the factors that affect Aricept medication persistence rate and the safety and efficacy in patients with Alzheimer's Disease in clinical practice

In France, about 1 million people 65 and older are diagnosed with dementia syndrome characterized by cognitive decline and impairment of functional capacity. The assessment of the level of functional autonomy is therefore an essential step in monitoring patients in Memory Clinic and can be estimated by the Lawton IADL questionnaire, assessing the patients' ability to perform daily tasks. In the Memory Clinic, the first estimate of the level of patient autonomy is achieved during a face-to-face interview between their primary caregiver and a nurse, using the IADL questionnaire. This assessment should be renewed every year. The IADL questionnaire is part of the information that the memories consultations shall transmit to the Alzheimer's National Bank (BNA). However, current practice has shown that the systematic collection is problematic in the organization of Memory Clinic. It is thus expected to collect this questionnaire by phone in order to measure changes in the level of autonomy during the disease, and improve the completeness of this collection. A study is conducted with the main objective to measure the reliability of the assessment of IADL questionnaires conducted during a telephone interview with the caregiver of the patient, in comparison to the reference mode: the face-to-face interview with the caregiver. Materials and methods The experimental design of the study will be a randomized crossover trial (crossover), including 394 patients divided into two branches. In the first part, the collection of the IADL questionnaire will be performed according to the reference method in the consultation (face-to-face interview with the nurse), the measurement will be repeated at 1 month intervals by phone. In the second part the sequence of execution modes will be reversed. The reliability of the measurement of the level of autonomy will be studied by comparing repeated measurements based on handover modes. The correspondence between the repeated measures will also be considered in terms of patient characteristics. The feasibility of administration of the questionnaire by phone mode will be evaluated. Expected results The mode of administration by phone should allow to obtain a reliable measurement of the level of patient autonomy when the administration is carried out in a standardized way. The study should also identify patients and situations for which this method of administration by phone may be appropriate.

High lipid peroxidation and altered antioxidant defenses have been frequently reported in Alzheimer's disease patients. The purpose of this study is to investigate susceptibility to photo-oxidation of isolated erythrocyte membranes, in patients affected by Alzheimer's disease and age- and sex-matched, non demented subjects.

Traumatic brain injury (TBI) and post traumatic stress disorder (PTSD) are common combat related problems and may be associated with a greater risk of Alzheimer's disease (AD). The purpose of this study is to examine the possible connections between TBI and PTSD, and the signs and symptoms of AD on Veterans as they age. The information collected will help to learn more about how these injuries may affect Veterans of the Vietnam War as they grow older, as well as Veterans of the current wars in Iraq and Afghanistan, who also have these types of combat related injuries.

Background: - The Baltimore Longitudinal Study of Aging (BLSA) is a long-term study of human aging. To see how the brain changes with age, researchers will study BLSA participants who are at least 60 years old. In particular, researchers are looking for early markers of possible Alzheimer's disease and other conditions that cause memory loss. To do so, they will give tests of memory and brain function, and stay in close contact with participants. Objectives: - To study cognitive changes that occur in normal aging and in people who develop memory problems. Eligibility: - Individuals at least 60 years of age who are participating in the BLSA. Design: There are three parts to this study. These study procedures will be done under the usual BLSA guidelines. Participants will take paper and pencil tests. The tests measure skills such as language, attention, memory, and problem solving. They will also ask questions about emotions and feelings. Participants will give the name and phone number of a person who knows them well and sees them often. Researchers will ask this person to fill out questionnaires on the effects of aging on the participant. These questions will monitor the participant's memory and ability to function independently. Participants will have regular phone calls between study visits. These calls will help to keep their information up to date. Participants will continue on this study for as long as they are able to participate.

The purpose of this study is to investigate the influence of the APOE genotype on brain morphology, function and metabolism, related to other factors such as cognitive reserve, cognition and episodic memory, in subjects at greater risk of developing AD.

There is a strong connection between hearing loss and cognitive impairment, particularly dementia, in old age. Worldwide, dementia affects approximately 5% of persons over the age of 65 years. Hearing loss is even more prevalent in old age, affecting an estimated one third of persons over the age of 65 years. Thus, there is likely a large degree of overlap between the impairments. Indeed, this overlap may influence older adults' everyday functioning, communication, social engagement and quality of life, as well as influencing the well-being of their family caregivers. This project will examine whether patients with hearing loss and Alzheimer's disease, the most common form of dementia, derive benefit the from hearing aids prescribed and fit to them following current best practice procedures in a geriatric audiology clinic. For the first time, a formal evaluation of the potential benefits of hearing aids for the patients' family caregivers will also be conducted.

The purpose of this clinical research study is to determine if a specific genetic allele is involved with the development of agitation in patients with late-onset Alzheimer's Disease (AD). The study will compare the results of genetic testing between two groups: individuals with late-onset AD who show signs of agitation and individuals with late-onset AD who do not show signs of agitation.
