Filter by:Dementia is a serious health problem showing an increasing prevalence rate with increasing age. In Norway, about 80% of nursing home patients have dementia. The mean age of nursing home residents in Norway is around 84 years. Disruptive and agitated behaviour affect 30-50% of all individuals with dementia at some point in the course of the illness. In addition, they have a combination of physical and psychological diseases which necessitates a close collaboration between different specialities in medicine and Old Age psychiatry. In collaboration with the communalities, our Old Age psychiatry services want to provide a new approach to this challenge and validate it on patient and personnel level.
The study will evaluate the safety & efficacy of AC-1204, a ketogenic compound, administered orally on a daily basis for 6 months. Following the 6 month double-blind phase of the study, subjects may enroll in an optional 6 month open-label extension phase. Efficacy will be evaluated by standard tests of memory and cognition, along with other measurements of activities of daily living and quality of life. Safety will be assessed by frequency of adverse events and changes in laboratory test results. Subjects will be stratified and outcomes will be separately analyzed based on apolipoprotein E4 genotype (APOE4).
The present study aims at combining biochemical methods with various types of imaging techniques to identify the pathophysiology of Alzheimer's disease (AD). The main interest is to find markers associated with the very early steps in the pathology of this disease. The investigators shall thus screen for i) molecules in cerebrospinal fluid (CSF) and plasma specific for AD, and ii) brain imaging markers (e.g. MRI and PET) that correlate to detailed clinical assessments. Biomarkers of interest would then be useful to: 1. Enable accurate detection of the disease early on. Such biomarkers need to specifically reflect the very early pathophysiology of AD and distinguish it from disorders with similar symptomatology, such as other types of dementia and major depression. The sensitivity and specificity of these biomarkers in combination with clinical assessment should be of at least 90%. 2. Enable prediction of the course of events of the disease, such as the disease rate in individual patients. Biomarkers that can predict the pattern of future symptoms will be extremely valuable. 3. Allow monitoring of early effects of new disease-modifying therapies (so-called surrogate biomarkers). Currently clinical therapeutic trials for AD require large patient groups together with long-term treatment. Both size of the groups and treatment time will be reduced with the help of surrogate biomarkers. 4. Study the pathogenesis of the disease. Biomarkers can be used to investigate in detail early alterations in AD patients. For instance, changes in the levels of certain molecules in CSF together with genetic predisposition could then be correlated to clinical signs and changes detectable by brain imaging. This can lead to identification of new therapeutic targets that could easily be monitored in future trials.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of multiple oral doses of CHF5074 in young healthy male volunteers.
Alzheimer's disease (AD) is the most common cause of progressive cognitive decline in the United States. AD is characterized by severe impairments in learning, memory and other cognitive abilities that significantly interfere with daily functioning. The neuropathologic hallmarks of AD consist of neuritic plaques, neurofibrillary tangles, and selective neuronal cell loss. Amyloid plaques, which contain Abeta protein, are believed to play an integral role in the development of AD. Elevated levels of Abeta in the brain are also correlated with cognitive decline. Alzheimer's (AD) develops insidiously, making it difficult to identify early, yet treatment is most effective when begun during the early stages of the disease. Thus, it has become important for researchers to identify markers of early AD. This project will examine the relationship between four potential markers that may indicate the early development of AD: 1. Mild cognitive impairment (MCI)or normal cognition 2. Practice effects 3. Amyloid plaque binding on 18F-PIB PET 4. Glucose hypometabolism on FDG PET This project will recruit 25 subjects from an ongoing community-based study of memory and practice effects in cognitively normal, community-dwelling individuals who are age 65 and over (NIA #5K23AG028417-05). Each subject will undergo positron emission tomography (PET) with both 18F-Flutemetamol and FDG. The overall objective of this companion project is to study the biodistribution and binding of 18F-Flutemetamol in these subjects using PET imaging, which will provide biological evidence to support the overall hypothesis that failure to benefit from practice on a learning paradigm is an early marker of AD.
The objective of this study is to present evidence-based medicine for development of clinical practice guideline through prospective study of Alzheimer's disease(AD) and mild cognitive impairment(MCI) in korea
This is a study to evaluate the safety of multiple doses of AAB-003 (PF-05236812) in patients with mild to moderate Alzheimer's Disease. Patients will receive either AAB-003 (PF-05236812) or placebo. Each patient's participation will last approximately 41 weeks.
The most common symptoms associated to senile dementia disease are confusion about schedules, hyperactivity... In this sense, these patients have frequently poor nutrition, resulting in malnutrition problems or malnutrition high risk.
The purpose of this study is to assess decision-making capacity in persons with Alzheimer's disease. First, our goal is to validate four French capacity assessment tools for persons with Alzheimer's Disease : a French version of the Competency Assessment Tool for Consent to Treatment and of the Competency Assessment Tool for Voting, two questionnaires assessing the capacity to appoint a proxy either to consent to treatment or to vote. Second, once validated, we plan these questionnaires to study decision-making abilities and their determinants in persons with Alzheimer's disease and control subjects.
The purpose of this observational study is to determine whether the vaccine (UB 311), targeting the N-terminal amino acids (1-14) of the amyloid beta peptide, has long-term immunogenicity and efficacy in individuals diagnosed with mild or moderate Alzheimer's disease (AD) who previously received UB 311-treatment. Amyloid beta was selected as the target antigen based on supporting evidence of the hypothesis that places the accumulation of amyloid beta at the initiating step of AD.
