Active clinical trials for "Dementia"

The objective of the ADDIA clinical Proof-of-Performance study is to validate the performance of ADDIA' blood biomarkers for diagnosis of Alzheimer's disease (AD). ADDIA clinical study is a multi-centre, non-interventional, prospective, proof-of-performance study with only one visit. About 800 well-characterized subjects will be recruited into 3 groups in 2:1:1 ratio, namely patients with Alzheimer's disease (AD), patients with non-AD neurodegenerative disease (NAD) and 200 control subjects (healthy as compared to their age). 400 patients with Alzheimer's disease (AD): 200 patients with mild AD, 200 patients with moderate-to-severe AD, 200 patients with non-Alzheimer's neurodegenerative diseases (NAD), 200 controls (healthy as compared to their age).

Motor slowing and cognitive slowing are more prevalent as we age. Importantly, the presence of both in an older person increases their risk of having dementia by ten times. Currently, there are no clinically meaningful predictors of progression to dementia in people with mild cognitive impairment (MCI). The main hypothesis is that subtle variations in gait while performing a simple cognitive task is a reliable, easy to perform, and feasible methodology to detect those older adults at higher risk of progression to dementia and also, at higher risk of further mobility decline and falls. Rationale. The Canadian population is aging. According to recent estimates, the proportion of the population aged 65 and older will increase rapidly from 13% in 2005 to 25% by 2031. This increase in proportion is accompanied by a considerable amount of disability and subsequent dependency which has major effects on both the quality of life of older adults and their caregivers, and on the Canadian health care system. An important goal of geriatric medicine is to reduce the gap between life expectancy and disability-free life expectancy by reducing disability and dependency in the later years of life. A substantial portion of this disability stems from two major geriatric syndromes: cognitive impairment and mobility limitation. The ultimate manifestations of these syndromes are dementia and falls. Interestingly, these manifestations often coexist in elderly people: falling is a common geriatric syndrome affecting about a third of older adults each year, and dementia affects about a third of Canadians aged 80 and over. Together, dementia and falls are responsible for much of the discomfort, disability, and health care utilization in older adults and each will become more prevalent as older Canadians are expected to number approximately $9 million by 2031. The combined direct cost of dementia and falls for the Canadian Health System is over $4.9 billion per year. Establishing reliable and easy to obtain predictors to accurately identify MCI patients at highest risk of progressing to dementia is essential first, to determine who will benefit from additional and/or invasive testing and second, to implement preventative strategies, including cognitive training, physical exercises, and aggressive vascular risk factors correction to delay progression. Even a modest one-year delay in dementia incidence could save Canada $109 billion over 30 years.

The purpose of this study is to investigate if behavioral intervention for dementia caregivers will decrease caregiver burden in caregivers of patients with dementia. This multicenter, randomized trial will be conducted with 80 dementia caregivers, who will be randomized into two groups. One group consists of 40 participants who will receive behavioral intervention and 40 who will not receive intervention (waitlist control). The waitlist control group will be also provided the same intervention after the intervention group has completed the intervention. The behavioral intervention consists of 90-min-session a day with an interval of two weeks for 2 months. The primary outcome measures are the changes in scores of Zaret's Burden Inventory and Philadelphia Geriatric Center for Moral Scale (PGCMS).

Traditionally, the more severity of dementia patients, the heavier the burden of the comparators, and in the clinical observation,the dementia patients with rich mental behavior symptoms are more burdened. Therefore, exploring the impact of psychological burden and different subtypes of different dimensions with Behavioral and psychological symptoms (BPSD) will more comprehensive understanding of the factors affecting the burden of caregivers. The starting point of this project is to analyze the relationship between the types of mental behavior symptoms of dementia patients and the emotional disorders of caregivers. The topic will analyze the correlation of psychological burden of caregivers and different symptom dimensions from the perspective of refinement, helping more effective identifying high-burden mental behavior symptoms in clinically , judging the risk of emotional problems in caregivers, and adopting better humanities or medical care, so that dementia patients can better adapt to care and improve the mental health of caregivers.

This study is to evaluate the results from an intervention designed to encourage older adults with dementia for their engagement in activities through their active participation of activity scheduling (AS).

The aim of this study is to characterize the deficit in critical components of personal identity (self-consciousness and social cognition) in patients with Alzheimer's disease (AD) and fronto-temporal lobar dementia (FTLD), compared to healthy elderly, combining a neuropsychology and multi-podal neuroimaging study. We posit that the alteration of some aspects of self-consciousness (autobiographical memory, nosognosia, metacognition) and social cognition (theory of mind and facial) results in personality changes in the patients, primarily due to the alteration of self-consciousness in AD and to social cognition in FTLD.

The purpose of this study is to apply a recently developed screening test for dementia, the Memory Orientation Screening Test (MOST) to two additional groups. Group one is composed of 150 elders who do not have dementia and are residing in the community so that we can determine what is a "normal" MOST score. These subjects will also be individually administered a one-hour battery composed of other commonly used tests of memory and information processing. Group two is composed of 150 elders who are administered the MOST by a nurse as part of their regular visit to the primary care doctor's office, and their scores will be compared against a rating of their cognitive ability made independently by the doctor or another nurse. Their scores will also be compared with a list of their medical problems and medications. Our hypothesis for the first group is that the MOST scores will be higher in the normal group than in the previous clinical groups and that MOST scores will correlate significantly with other neurocognitive tests. Our hypothesis for the second group is that the MOST can be administered quickly and easily by briefly trained nurses, that it will compare highly with doctor opinions, and that patients with known medical conditions related to dementia, such as hypertension or diabetes, will have lower MOST scores than patients in better health.

This study evaluates an educational brochure tailored to caregivers of people with Alzheimer's disease, Parkinson's disease dementia, Lewy body disease, frontotemporal dementia, and vascular disease dementia. The goal of the brochure is educating caregivers about the decreased ability to detect emotion and decreased empathy that can be seen in dementia, increasing caregiver competence in providing care, and teaching caregivers ways to manage over time that lessens burden and improves quality of life.

Coronavirus disease 2019 has forced worldwide the implementation of unprecedented restrictions to control its rapid spread and mitigate its impact. The Spanish government has enforced social distancing, quarantine and home confinement. This restriction of daily life activities and separation from loved ones may lead to social isolation and loneliness with health-related consequences in community-dwelling older adults with mild cognitive impairment or mild dementia and their caregivers. Additionally, an inadequate access to healthcare and social support services may aggravate chronic conditions. Technology home-based interventions emerge for combating social isolation and loneliness preventing the risk of viral exposure. The aim of this multicentre cohort study is to explore, analyze and determine the impact of social isolation on: 1) cognition, quality of life, mood, technophilia and perceived stress of community-dwelling older adults with mild cognitive impairment or mild dementia, and on caregiver burden; 2) health and social care services access and utilization, and 3) cognitive, social and entertainment use of ICTs. This study will be conducted in two Spanish regions Andalucía (Málaga) and Cataluña (Tarrasa). In total 200 dyads, consisting of a person with mild cognitive impairment or mild dementia (PMCI/MD) and their informal caregiver will be contacted by telephone. Potential respondents will be participants of the SMART 4 MD (N=100) and TV-AssistDem (N=100) clinical trials. The change in means in the variables will be analyzed comparing baseline results in the previous studies with those during and after confinement using the ANOVA test of repeated measures or the non-parametric Friedman test if appropriate. The performance of a multivariate analysis of variance (ANCOVA) to introduce possible covariates will also be contemplated. A 95% confidence level will be used.

Background With the global population aging and life expectancy increasing, dementia has turned a priority in the health care system. In Chile, dementia is one of the most important causes of disability in elderly, corresponding nearly to 40% of cases, and the most rapidly growing cause of death in the last twenty years. Cognitive complaints are considered a marker able to predict cognitive and functional decline, incident mild cognitive impairment (MCI), and incident dementia. The Gero cohort is the Chilean core clinical project of the Gerocenter on Brain Health and Metabolism (GERO), whose aim is to establish the capacity in Chile to foster cutting edge and multidisciplinary research on aging. Objective This study has two main objectives. First, i) to analyze the rate of functional decline and progression to clinical dementia and their risks factors (biomedical, imaging, psychosocial, and clinical) in a community-dwelling elderly with subjective cognitive complaint, through a population-based study. Second, ii) to build the capacity to undertake clinical research on brain aging and dementia disorders and create Data-Bank and Bio-Banks with an appropriate infrastructure to further studies and facilitate access to the data and samples for research. Methods The Gero cohort aims at recruiting 300 elderly subjects (>70 years) from the community of Santiago (Chile), following them up for at least 3 years. Eligible people are non-demented adults with subjective cognitive complaint, which are reported either by the participant, the proxy or both. Participants are identified through a household census. The protocol of evaluation is based on a multidimensional approach including socio-demographic, biomedical, psychosocial, neuropsychological, neuropsychiatric and motor assessments. Neuroimaging, blood and stool sample samples are also included. This multidimensional evaluation is carried out in a baseline assessment and 3 follow-ups assessment, at 18 and 36 months. In addition, in months 6, 24, and 30, a telephone interview is done in order to keep contact with the participants and to assess general well-being.
