NCT01677754
This Phase II, multicenter, randomized, double-blind, parallel-group, placebo-controlled study will evaluate the efficacy and safety of RO4602522 in participants with moderate severity Alzheimer's disease. Participants who are taking background therapy of acetylcholinesterase inhibitors (AChEI) alone or in combination with memantine for at least 4 months before screening will be randomized to receive either one of two doses of RO4602522 or placebo for 12 months.
NCT00814502
The purpose of this research study is to compare the effectiveness of Zolpidem CR to that of placebo in improving sleep efficiency in people with dementia admitted to the hospital because of their symptoms. You can participate in this study if you have dementia of the Alzheimer's type or vascular dementia. This study involves placebo; a placebo is a tablet that looks exactly like Zolpidem CR, the study drug, but contains no active study drug. We will use placebos to see if the study results are due to the study drug or due to other reasons. Zolpidem CR is also called Ambien CR and is widely available by prescription. Zolpidem CR is approved by the U.S. Food and Drug Administration (FDA) for the short-term treatment of insomnia (trouble falling or staying asleep).
NCT02118701
Shared Decision Making (SDM) is defined as a process where healthcare professionals and patients make decisions together, using the best available evidence. SDM, as a communication and decision method, can be used also with persons suffering from dementia. Yet, SDM with persons with dementia or even with their family caregivers is not widespread. The present research project aims to develop and evaluate an SDM framework in care planning to be implemented in long-term care facilities, in order to obtain a constantly developing care plan that focuses not only on the medical, physical, psychosocial and spiritual needs of the resident, but that considers and documents his preferences and the actions taken by caregivers to meet them. The current project is a controlled exploratory study. Case studies that involve a triad in each case, composed by the resident with moderate or severe dementia, his family caregiver and the professional usually taking care for the resident, will be used (n=16 professionals; n=40 residents; n=40 family caregivers). Professional caregivers of two nursing homes, one located in Italy and one in the Netherlands, will receive a specific training in SDM principles and will guide the SDM interview within the triad. Primary outcome will be the proportion of residents whose preferences and needs, together with the related actions to meet them, are known, documented and satisfied in their 'life-and-care plans'. Secondary outcomes are the residents' and family caregivers' quality of life; the family caregivers' sense of competence and the healthcare professionals' job satisfaction. Semi-structured interviews and focus group interviews will be performed to assess satisfaction with the intervention and barriers and facilitators to its implementation. Assessments are performed at baseline and six months after the intervention. We hypothesize that the use of the SDM process in care planning will increase the number of met needs and will improve the residents' and family caregivers quality of life, the family caregivers' sense of competence and the healthcare professionals' job satisfaction. The key element of this study is that it will contribute to our knowledge about the efficacy and feasibility of an SDM framework in care planning in long-term care facilities with persons with moderate to severe dementia.
NCT01702480
This is a single centre, 2 part study in older subjects. Part 1 (Pharmacokinetic \[PK\] Assessment) is a double blind, randomized, placebo-controlled 4-period crossover study investigating the PK profile of four different doses of GSK2981710. Eight subjects will receive a single dose of GSK2981710 10 gram (g), 20 g, 30 g, 40 g or placebo in the morning and have PK assessments (every 0.5 hrs up to 8 hrs post-dose) throughout the day in each period. Each subject will complete a total of four dosing sessions and 4 days of PK assessments in 2 weeks. The Part 1 PK data will be used for dose selection and pharmacodynamic (PD) assessment period in Part 2. If the data from Part 1 is inconclusive, an additional 8 subjects may be recruited and Part 1 repeated (possibly dropping some doses) to increase confidence. A subject's total participation in Part 1 of the study will last a maximum of approximately 7 weeks including screening. Subjects who have completed Part 1 may be screened for eligibility and enrolled for Part 2. Part 2 (PD Assessment) is a double blind randomized, placebo-controlled 2-period crossover design with 14-day treatment periods investigating the efficacy (cognitive performance) and tolerability (gastrointestinal \[GI\] side effects) of single daily dose of GSK2981710 selected from Part 1. Part 2 of the study will include the Screening period, two Baseline assessments (6-8 days before each Treatment period) and two 14-day treatment periods separated by a minimum 7-day washout period and follow-up visit of 3 to 5 days. Approximately 50 to 80 subjects will be randomized to either GSK2981710 or placebo. The PD assessments will be performed on 6 occasions for each subject: at 2 baselines (6 to 8 days before Day 1 of each treatment period), post-dose on the Day 1 of each treatment period to assess acute effects and on Day 15 of each treatment period (which is the day after the final dose) to assess chronic effects. A subject's total participation in Part 2 of the study will last approximately up to 12 weeks including screening.
NCT00376051
Frontotemporal lobar degeneration(FTLD) is a common cause of early-onset dementia. FTLD is characterized multiple behavioral symptoms including mental rigidity, irritability, emotional blunting, disinhibition, apathy, and aggression. These behavioural disturbances are particularly important because they increase caregiver burden and may lead to earlier institutionalization. While the causes of FTLD are largely unknown, there is a great deal of evidence suggesting that a brain chemical called serotonin regulates many of the behaviours that are disturbed in FTLD. Our objective is therefore to determine whether dysfunction in the brain's serotonin system is responsible for behavioural problems among FTLD patients. We hope to take the first steps towards a scientific understanding of the behavioural symptoms of FTD, and use our findings to support a larger study optimizing the treatment of targeted behavioural disturbances in FTLD using the antidepressant citalopram. Citalopram increases transmission by serotonin; we plan to use this medication to determine whether there are any differences in how the serotonin system functions in FTLD patients who display different levels of behavioural disturbances. Patients will be given citalopram and will have their blood drawn after 2 and 3 hours to determine plasma levels of the hormones cortisol and prolactin at those times. These hormones are good indicators of serotonergic functioning in the central nervous system. We expect that patients with lower levels of serotonergic functioning will have more severe behavioural disturbances and be less responsive to treatment with citalopram. Following their first test day, we will provide patients with a 6-week supply of citalopram, and assess them for any changes in behaviour at the end of this treatment. This study aims to obtain a better understanding of how changes in the serotonin system relate to behavioural symptoms in FTLD patients. Using the information from this pilot study, we can plan a larger study to determine whether certain behaviours will respond to treatment with citalopram, and if so, determine whether it is possible to predict which patients, based on individual characteristics, are most likely to respond to this treatment. This methodology will therefore not only provide a scientific rationale for treatment of FTLD, but also provide guidance for ongoing, individualized therapy.
NCT02341898
Background: Physical restraints as bedrails and belts are still regularly applied in German nursing homes despite clear evidence showing their lack of effectiveness and safety. In a cluster-randomized controlled trial, the efficacy of a guideline-based multicomponent intervention has been shown with a significant reduction in physical restraints use without adverse events. The present study aims to apply different versions of the original intervention in nursing home residents in four different regions throughout Germany in order to evaluate the effectiveness of the programme. Methods/Design: Pragmatic cluster-randomized controlled trial comparing two intervention groups ((1) updated original programme and (2) brief version of the updated programme) with a control group (3) receiving printed study materials (optimized usual care). Intervention (1) consists of an information programme for all nurses, additional training and structured support for nominated key nurses, and provision of printed study material and other supportive material. For intervention (2) nurses' training is only optional carried out facultatively by key nurses who have received an additional train-the-trainer module. The control group (3) receives printed study material only. Overall, 120 nursing homes including approximately 10800 residents will be recruited, randomized to one of the three groups and followed up for 12 months. The primary outcome is defined as proportion of residents with at least one physical restraint at 12 months. Physical restraint use will be assessed by direct observation. Secondary outcomes are residents' quality of life as well as safety parameters as i.g. falls and fall-related fractures. Process and cost measures will also be assessed.
NCT02141971
Non-randomized natural history study involving 12 subjects with Down Syndrome, who are aged 30-60 years old. This study will observe 3 different groups: four non-demented subjects between ages 30-40 years old, four non-demented subjects between ages 40-50 years old, and four demented subjects 50-60 years old. Currently available longitudinal data in DS suggest a high rate of transition to dementia from the late 40s through the early 50s of these individuals. This, together with the universal presence of plaques in DS by their mid 40s makes this age range ideal for studying the development of AD.
NCT02035982
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.

The investigators explore the presence of AD factors beta-amyloid and tau in CSF and plasma to verify AD diagnosis in patients with acute hip fracture. Clinical dementia test is performed prior to operation. Blood samples and CSF samples are collected at surgery and blood samples are collected postoperatively at intervals. Mortality is assessed at 30 days, 3 months and 1 year. Morbidity is assessed at , 3 months and \>1 year. Neuromarkers specifically addressing the inflammatory component are to be analyzed and correlated to outcome together with AD markers, as above.
NCT02131545
Quetiapine, a second generation antipsychotic, is only available as oral tablets. However, topical and rectal formulations have been produced in compounding pharmacies. There is no data available suggesting that topical or rectal formulations provide serum levels similar to oral medication. In the clinical setting, when oral administration of quetiapine is not possible (for example, when a patient is extremely ill physically or mentally or both), clinicians and pharmacists have collaborated in such cases and have at times had to administer quetiapine compounded in other dosage formulations such as rectal or topical formulations. Despite clinical effectiveness of these other formulations, there are no available studies that have investigated blood levels of the drug other than the oral form. The investigators are therefore designing this pharmacokinetic study to evaluate the the systemic absorption of quetiapine in oral, rectal and topical formulations. If the investigators are able to demonstrate detectable levels from rectal and topical quetiapine formulations compared to the oral form, this knowledge will enhance clinical psychiatric practice by providing a more broad route of administration for quetiapine which is a commonly used drug for psychiatric symptoms.
NCT01454453
Drugs such as amisulpride, known as antipsychotic drugs, are used to treat troublesome and distressing symptoms in older people. Although these drugs can be beneficial, they are associated with side effects, particularly in patients with dementia and schizophrenia- like illness. There is an urgent clinical need to understand why this is the case, to guide treatment strategies. This study aims to utilise brain imaging techniques that measure the action of antipsychotic drugs in the brain to explore the causes of this susceptibility in older people with dementia and schizophrenia-like illness, and translate these findings into direct patient benefit. The aim of the study is to investigate and compare the relationship between the action of amisulpride at brain sites during the first 10 weeks of amisulpride treatment in two patient groups - Alzheimer's disease and schizophrenia-like illness. Imaging data will be combined with data on drug dosage, levels of drug in the bloodstream and clinical response (symptom reduction and motor side effects) during dose titration.Dose-response modelling will be carried out in both groups to establish the minimum clinically effective dose of amisulpride, optimum dose range and impact of variability and covariates on exposure-response relationships
NCT03120741
This study is an observational study that uses daily activity and environmental sensing techniques to establish behavioral models of early dementia patients and cognitive healthy function to assess their daily behavior and determine their activities. Specifically, the team will collect information on a number of wireless sensors for dementia, mild cognitive impairment and healthy elderly residents, and use special mathematical models to establish the behavior of the two groups of subjects Model. The model will be developed a reliable algorithm to assess health risk of the subjects.
NCT01607476
The intent of this research protocol is to test the equivalency of two amyloid imaging drugs (C11 Pittsburgh Compound B and F18 Flutemetamol). The investigators hypothesize that there will be no significant difference in the distribution of the agents to areas of amyloid deposition in the brain or to other normal brain structures. Recent data have shown similarity in the distribution of the drugs in subjects with Alzheimer's disease (AD) or mild cognitive impairment (MCI). No comparison data of the two PET drugs in normal subjects has been published. It is important to understand differences in the images and biodistribution from the two drugs in normal subjects as nonspecific accumulation of the drugs in brain structures such as white matter appear to differ slightly and could affect image performance.
NCT00086138
The purpose of this study is to learn whether treating individuals with Alzheimer's disease and depression with the anti-depressant medication sertraline (Zoloft) is helpful to people with Alzheimer's disease and to their families and caregivers.
NCT02294513
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.
NCT00267124
The purpose of this study is to determine the effects of exercise and cardiorespiratory fitness on age-related brain changes.
NCT02267057
The purpose of this study is to determine whether pain treatment can reduce symptoms of depression in patients suffering from dementia and depression. Depression is commonly diagnosed in patients with dementia. If the investigators find a reduction in depressive symptoms when pain treatment is applied, this will support the hypothesis that undiagnosed pain may present itself as depression in patients with dementia.
NCT02166827
To evaluate the long-term efficacy of the NeuroAD system
