NCT03481933
Within the spectrum of fronto-temporal lobar degeneration (FTLD) semantic dementia (SD) causes profound language dysfunction. SD damages semantic processing typically in the temporal poles (anterior temporal lobes, ATL). It is an early onset disease (often before 65 years of age) affecting about 4000 patients in France and for which no validated treatment is available. For several years a growing number of studies have explored the effects of transcranial stimulation (TCS) on aphasic patients following stroke. Several studies have targeted left-sided language areas and/or homotopical right-sided regions with excitatory or inhibitory TCS, respectively, according to the principle of inter-hemispheric inhibition. In addition, repetitive multi-day TCS has provided evidence for long-lasting language effects (\>6 months) presumably linked to stimulation-induced neuroplasticity. Such investigations have provided promising results and have demonstrated that the stimulation site is a determining factor by showing that stimulation of cortical areas belonging to the language network usually results in more convincing effects than stimulating areas outside that network. Despite these findings the use of TCS in degenerative language diseases, such as primary progressive aphasias including SD, has only been explored in few small cohort studies and, surprisingly, they have not targeted language-related cortices. This project proposes the application of multi-day repetitive TCS with direct current (tDCS) in a large population of SD patients (N=60). It is built on a exploratory investigation of our team which has used three single tDCS sessions in a double-blind sham-controlled study. Excitatory and inhibitory tDCS to the left and right temporal pole, respectively, demonstrated highly significant transient effects (20 min) on semantic processing in 12 SD patients, providing 'proof of concept' and the rationale for this project. The aim here consists of using repetitive multi-day tDCS for a potential therapeutic outcome leading to long-lasting semantic improvement via neuroplasticity. The project is grounded on 2 hypotheses: i) tDCS to temporal poles (left-excitatory, right-inhibitory) reactivates semantic processing in SD, ii) repetitive tDCS during ten days could induce neuroplasticity and therapeutic language improvement.
NCT03443973
This randomized, double-blind, placebo-controlled, parallel group study will evaluate the efficacy and safety of gantenerumab versus placebo in participants with early (prodromal to mild) AD. All participants must show evidence of beta-amyloid pathology. Eligible participants will be randomized 1:1 to receive either subcutaneous (SC) injection of gantenerumab or placebo. The primary efficacy assessment will be performed at the end of the double blind period at week 116. Participants will then be offered to enter into an open-label extension (OLE). Participants not willing to go to the OLE will participate in a long term follow-up period for up to 50 weeks after the last gantenerumab dose.
NCT06191952
In this study the investigators explore a pragmatic strategy to increase cognitive screening rates in the community. The investigators will compare the monetary value of different combinations of SCD questionnaires, digital cognitive tests, and blood Alzheimer's Disease (AD) biomarkers to identify the best approach for primary care settings.
NCT04533815
This was a pilot study (R61) to prepare for a full clinical trial (R33) aiming to improve clinical outcomes for an important, growing, and vulnerable population-nursing home (NH) residents with Alzheimer's disease or related dementias (ADRDs). The goal was to pilot and refine the research methods and intervention that would be subsequently evaluated in a full implementation trial (hybrid type III). The goal of the evidence-based intervention (LOCK) that was refined in this pilot study and will be evaluated in the subsequent full clinical trial is to improve the sleep of NH residents with ADRD.
NCT05153161
An estimated 70% of the 7.2+ million people in the U.S. with Alzheimer's Disease and Alzheimer's Disease-Related Dementias experience agitation, characterized by poorly organized and purposeless psychomotor activity that diminishes their quality of life. The goal of this Small Business Innovation Research (SBIR) project is to develop a wearable therapy device that automatically senses rising agitation, and alerts caregivers while deploying calming voice and music therapy to help them avoid crisis level behavior. This device will improve health outcomes for AD/ADRD sufferers and reduce the substantial stress suffered by their caregivers.
NCT06180252
The aim of this study is to understand regional variations in acetylcholine esterase activity in Alzheimer's disease. In this study the aim is to identify by PET the physiological values of the regional activity of acetylcholine esterase using the 11C PM4 tracer and to study by PET and 11C PM4 the brain activity of acetylcholine esterase in a group of patients with Alzheimer's disease, enrolled according to the inclusion and exclusion criteria. The PET data will be correlated with the clinical, neuropsychological and morphological data acquired by MRI and with the clinical-cognitive outcome.
NCT03840837
This is a single-site non-randomized open label pilot study. The investigators will use accelerometer-based instrumented gait analysis and computerized cognitive testing to study the interaction of motor and cognitive dysfunction in Parkinson disease dementia (PDD), and the effect of rivastigmine on motor and cognitive performance. All study participants will be tested for motor and cognitive performance at baseline (arm 1). A subgroup of study participants will then be treated with rivastigmine for 12 weeks (arm 2), and the effect of this treatment on gait measures and cognitive measures will be analyzed at the follow-up visit 12 weeks after the baseline visit. Specifically, we will determine which components of motor and cognitive impairment are associated with each other, and which components of the two domains respond to rivastigmine-mediated stimulation of cholinergic neurotransmission.
NCT04277104
With aging the amount of slow wave sleep decreases drastically and this disruption is markedly exaggerated in older adults suffering from mild cognitive impairment and Alzheimer's disease. Critically, the disruption of slow wave sleep and cognitive decline seem bidirectionally linked forming a vicious cycle. In the long run, improving slow wave sleep might be a useful intervention tool to delay the onset of cognitive decline. The present study aims at improving slow wave sleep and memory functions through a closed-loop acoustic stimulation approach. A closed-loop algorithm is used that detects slow waves in the electroencephalogram and is programmed to present short tones (50 ms) in the rhythm of these waves. This procedure has shown to boost both slow wave sleep as well as memory performance, mainly in young adults and when applied for one night. Here, the investigators apply tones via multiple consecutive nights and assess memory performance during this 3-night intervention.
NCT04575337
The project of Bio-AD is a population- based cohort study among the elderly in China. The project includes not only Alzheimer's disease (AD including familial AD and sporadic AD), but also other clinical stage of AD, as well as elderly people with normal cognitive function. The project will collect, detect and screen the special biomarkers at different clinical stage of AD based on body fluid, gene and brain image. The standard and consistent assessment protocols are employed to obtain clinical, cognitive, genetic, neuroimaging and biospecimen data. The purpose of this project is to establish a panel of biomarkers which could be used to diagnose AD at the early stage, and to establish a risk prediction models for AD to predict the 5-years risk of the onset and progression of AD among elderly population in China.
NCT05993572
Depending on the YASAM project which was established to home-visit evaluate community-dwelling older adults (80 years of age and over), we aimed to determine the prevalence (prevalence) of geriatric syndromes (dependence, frailty, malnutrition, depression, dementia, comorbidity burden, polypharmacy) in these individuals and to determine possible changes in the follow-up of the patients during the 2-year follow-up period. (HEAVEN trial)
NCT05315960
This study aims to develop a new measure which can accurately assess social connection for people with dementia living in long-term care homes. The Social Connection in Long-term Care home residents (SONNET) study will use interviews and focus groups with people affected by dementia and long-term care residents to establish what aspects of social connection are important for people living in care homes. These findings and a review of other studies and measures will be used to develop a new measure or measures of social connection which will then be tested in a study based in care homes in Canada and the UK.
NCT05082883
In the United States and around the world, people are living longer lives. As the population ages, so does the number of older adults who may experience declines in memory, attention, reasoning, or other thinking skills. Some of these changes in cognition can be treated and reversed if caught early. Others can be slowed down and hopefully one day prevented. Unfortunately, people with cognitive decline or very mild dementia often are not recognized until late in the disease course when treatments are less effective. As the first health care professional most people reach out to about medical concerns, primary care providers play a critical role in detecting cognitive decline early. While many primary care providers conduct cognitive screening at Medicare Annual Wellness Visits and when patients voice concerns, 9 out of 10 would like more information about who to screen, which assessment tool to use, and what to say if screening is positive. Deciding who to screen with a brief cognitive assessment tool is a key part of the process because not everyone needs to be screened, and primary care providers already face time pressures to address the obvious and immediate concerns of their patients. The long-term goal of this project is to develop a risk assessment and cognitive screening tool that requires minimal time and effort from primary care providers or their staff and is sensitive to cognitive decline in older adults from diverse educational and racial/ethnic backgrounds. The tool will be integrated into electronic health record systems to make it easy for primary care providers and patients to see results. The specific aims of the first phase of the project are to modify an existing dementia risk screening index to identify older adults who are at high-risk for cognitive impairment, develop a brief cognitive assessment tool using tasks that are easy for older adults to perform yet are sensitive to cognitive decline, confirm their utility in 150 people with varying levels of cognitive abilities that have already been well defined, and test ways to integrate findings into the electronic health record. The specific aims for the second phase are to further test the effectiveness of the newly developed tool in 250 older adults receiving care in a primary care clinic, to find out from primary care providers using the tool how much they liked it and if it was useful and easy to use, and to integrate findings into multiple electronic health record systems. Findings from this project will fill a gap in the existing toolkit of primary care providers and will make screening for cognitive decline quick, easy, and effective.
NCT02155946
The aging US population threatens to overwhelm our healthcare infrastructure, especially since the rate of Alzheimer's disease (AD) alone is expected to triple in the coming decades. Memory cause functional impairment, reduced quality of life, increased caregiver burnout, and eventual institutionalization. The diagnosis of mild cognitive impairment (MCI) identifies those with memory deficits but who remain relatively independent in everyday life. MCI provides a window for interventions that target memory functioning. The proposed study focuses specifically on a groundbreaking combination of mnemonic rehabilitation and non-invasive brain stimulation. The main idea is that brain stimulation can enhance functioning in the specific brain regions/networks, thereby increasing the patients' ability to benefit from different types of memory rehabilitation. This will be a randomized, double-blind study (active vs. fake brain stimulation), that provides multiple treatment session. Outcome will be examined using both laboratory-based and real-world memory testing as well as brain imaging. This first-of-its-kind study has the potential to meaningfully translate more "basic" science findings into neuroanatomically targeted and functionally meaningful treatments for our aging population.
NCT04797715
This is a multi-center, double-blind, placebo-controlled, randomized withdrawal study to evaluate the efficacy and safety of AXS-05 compared to placebo in the treatment of agitation symptoms in subjects with agitation associated with Alzheimer's disease.
NCT04495686
There are an increasing number of people in the U.S. with Alzheimer's disease and other dementias. Traumatic brain injuries (TBIs) are also common among both civilians and military personnel, and TBIs increase a person's risk for dementia. Providing care for a person with dementia is stressful. Dementia caregivers can experience difficulties including stress, depression, and reduced quality of life. Coordinated dementia care is known to benefit people with dementia and their caregivers. However, many caregivers do not have access to these supportive programs. Our project studies the benefits of telehealth as a new way for caregivers to receive coordinated dementia care services. We will offer 75 caregivers a 12-month caregiver support program delivered using telehealth (for example phones, tablets, computers). Caregivers of both Alzheimer's disease and TBI-related dementia will be included, and the program will be evaluated for effectiveness in both groups as well as in a control group. The information from our study will help improve quality of life for caregivers and individuals with dementia, including military members and Veterans. Our results will also help both civilian and military health professionals develop effective programs to support families living with dementia. Policy makers and organizational leaders can use the information to fund programs that best help families and communities facing dementia and TBI dementia.
NCT01920100
This project is based on a three-year program that aims to improve the knowledge of the socioeconomic consequences of dementia in Norway. By including patients with and without dementia in four different cohorts (from nursing homes, from memory clinics, home-dwelling persons with dementia and elderly persons without dementia), the project's aim is to describe the course of dementia, the economical cost of dementia and to look into possible risk factors for dementia.
NCT05844241
The greying of the world is leading to a rapid acceleration in both the healthcare costs and caregiver burden that are associated with dementia. There is an urgent need to develop new, easily scalable modalities of support to reduce agitation and anxiety in those with dementia. There is evidence that music interventions reduce agitation and anxiety in those with dementia. LUCID has developed a novel digital music therapeutic product that uses a reinforcement learning AI agent to curate and personalize the musical playlist while incorporating binaural theta auditory beat stimulation (ABS) to reduce anxiety and agitation in those with dementia. This study will be conducted remotely with study hardware (tablets and Bluetooth speakers) being shipped to caregivers/participants' homes. The study will take place over a 2-week period, with participants completing 4 one-hour sessions per week along with an additional 1-hour follow-up interview session. Forty-eight participants with mild to moderate dementia (as defined by the Montreal Cognitive Assessment) will be evenly randomized to one of two conditions. The control condition consists of a selection of 30-minute audiobooks which the participant has the freedom to select from. The experimental condition consists of music and binaural ABS curated by LUCID's AI system. Participants' caregivers will complete baseline questionnaires assessing the participants' anxiety, agitation, and mood. They will also complete these questionnaires before and after each experimental session. The investigators hypothesize that the LUCID AI music curation system will have a greater agitation and anxiety reduction compared to the audiobook control condition.
