Filter by:The purpose is to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an Alzheimer's disease (AD)-causing mutation. Part 1 will determine if treatment with the study drug prevents or slows the rate of amyloid beta (Aβ) pathological disease accumulation demonstrated by Aβ positron emission tomography (PET) imaging. Part 2 will evaluate the effect of early Aβ plaque reduction/prevention on disease progression by assessing downstream non-Aβ biomarkers of AD (e.g., CSF total tau, p-tau, NfL) compared to an external control group from the DIAN-OBS natural history study and the DIAN-TU-001 placebo-treated participants.
This is a 26-week randomized, double-blind, placebo-controlled trial. We will enroll patients with aMCI or mild AD. All patients will receive 2 weeks of tDCS (5 sessions per week, 10 sessions in total) during the first 2 weeks of the study, and will also be allocated randomly to either of 4 treatment groups for 24 weeks: (1) Dose A group; (2) Dose B group; (3) Dose C group; (4) placebo group. We will assess the patients every 8 weeks during the treatment period (weeks 0, 10, 18, and 26). We hypothesize that augmentation with certain dose of DAOIB will yield better effect than tDCS alone in improving the cognitive function, global functioning and quality of life in patients with aMCI or mild AD.
One of the traditional therapies for restoring the ability of speech in aphasic patients is Melodic Intonation Therapy (MIT), in which everyday phrases are taught in a singing-like manner. The suggested mechanism for speech recovery is that because of the sharing of brain resources for language and music, the regions normally reserved for singing can be trained to help compensate the speech functions originally subserved by the damaged regions. However, this therapy has primarily been applied to speakers of non-tone languages, in which prosodic features carry a more important role than pitch features in conveying meanings. It remains unknown whether MIT will be equally applicable for speakers of tone languages, in which pitch features likely play a more important role. Another uncertainty concerns whether the efficacy of MIT can be extended to patients with expressive speech impairment due to dementia. This pilot study aims to find out the efficacy of MIT for speech-impaired dementia patients in different verbal tasks. The results of this study will provide preliminary empirical evidence to establish the utility of MIT for Cantonese speakers in Hong Kong.
This study is designed to evaluate the safety and efficacy of exosome deployment with concurrent transcranial ultrasound in patients with refractory, treatment resistant depression, anxiety, and neurodegenerative dementia.
This study aims to evaluate the effect of a long-term group cognitive stimulation (CS) program on the cognitive function of institutionalized elderly people with neurocognitive disorders. The study also aims to assess the program's feasibility in institutions located in the Portuguese town of Oliveira do Bairro. The investigators propose the realization of a quasi-experimental longitudinal study with a one-group pretest-posttest design. The subjects will participate in CS sessions as part of a group, once a week, for one year, while maintaining their usual care in the institution. The program will have 47 sessions, once per week, with 1 hour each. In each participating institution, one group will be formed. In groups composed by participants with mild neurocognitive disorder, the maximum number will be 10 participants per group, in groups composed by participants with major neurocognitive disorder, the maximum number will be 6 participants per group. In each institution, patients who meet the inclusion and exclusion criteria will be selected to become part of a cognitive stimulation group program.
Dementia is widely prevalent and results in high direct and indirect health costs. Dementia is associated with stress, anxiety, and depression in both patients and caregivers, and caregiver burden is extremely common. Treatment protocols for patients and caregivers are unclear and insufficient; drug treatments to manage behavioural and psychological symptoms of dementia can yield serious negative side effects, and caregivers may not have access to one-on-one psychotherapy due to high costs and long wait times. Yoga is an ancient Indian mind-body practice that uses physical postures, breathing exercises, and meditation. Yoga may be a viable therapeutic modality to address the psychological challenges associated with dementia in patients and caregivers, as it has been shown to decrease stress and improve anxiety and depressive symptoms in various populations. Recent research has suggested that patients with dementia and their caregivers may also experience positive effects on their mental health from practicing yoga. Furthermore, when yoga is taught in a gentle and mindful manner, it is generally not associated with any negative side effects. While there is preliminary data on dyadic exercise interventions for dementia patients and their caregivers, to date no research has examined the effectiveness of a dyadic yoga intervention on stress, anxiety, and depression. The investigators propose an 8-week study of a dyadic chair yoga program for patients with mild to moderate dementia and their caregivers (n = 30-40 participants). Our primary outcome of interest is changes in perceived stress, while secondary outcomes include changes in symptoms of depression and anxiety. The investigators will also look at the effects of the chair yoga program on caregiver burden, quality of interactions, well-being, mindfulness, and self-compassion. All outcomes will be assessed before the program starts and upon its termination. Participants will attend a 1-hour weekly group yoga class (4-10 participants per group) with their dyad for 8-weeks, and will also be given a video recording of a yoga class to practice together at home as often as possible. The investigators hypothesize that after the 8 week yoga program, patients and caregivers will report lower stress, as well as reduced symptoms of anxiety and depression. Results will be available mid-2020.
Informal caregivers of people with dementia are at greater risk of developing physical and mental health problems when compared to the general population and to informal caregivers of people with other chronic diseases. Internet-based interventions have been explored in its potential to minimize the negative effects of caring, accounting for their ubiquitous nature, convenient delivery, potential scalability and presumed (cost)effectiveness. iSupport is a self-help online program developed by the World Health Organization to provide education, skills training and support to informal caregivers of people with dementia. This intervention study aims to determine the effectiveness of a Portuguese culturally adapted version of iSupport to decrease caregiver burden, symptoms of depression and anxiety, and to improve quality of life, positive aspects of caregiving and general self-efficacy. The study has two arms: access to "iSupport" for three months or access to an education-only e-book. iSupport is grounded in problem-solving and cognitive behavioral therapy techniques and it consists of 23 lessons organized around 5 modules: 'Introduction to dementia'; 'Being a carer', 'Caring for me', 'Providing everyday care', and 'Dealing with behaviour changes'. One hundred and eighty four participants will be recruited by referral from national Alzheimer's associations. Participants will be included if they match the following criteria: being 18 years or older and provide e-consent; being a self-reported non-paid caregiver for at least 6 months; caring for a person with a formal diagnosis of Alzheimer's disease; being skilled to use internet; and experience a clinically relevant level of burden or depression or anxiety symptoms. Data is collected online, resorting to self-administered instruments, at baseline, 3 and 6 months after baseline. A two-sided alternative hypothesis was assumed for this study: Mean caregiver burden at 3 months after baseline is different in informal caregivers of people with dementia assigned to the iSupport program as in those assigned to a minimal education-only intervention. Findings from this intervention study will offer evidence to support an informed decision making on scaling up iSupport as a new intervention program with minimal costs aimed at minimizing the psychological distress of informal caregivers of people with dementia in Portugal and elsewhere.
By the year 2038, over a million Canadians are expected to have Alzheimer's disease, a type of dementia. Dementia increases the risk of nursing home placement among the elderly more than fivefold. Given the exceptionally vulnerable nature of this patient population, there is a pressing need to ensure that the clinical care they receive is evidence-based, tailored specifically for them, and meeting the high standards of quality that would be expected in any other health-care setting. Delirium is a sudden and severe change in brain function that can cause a person to appear confused or disoriented, have memory loss, and have difficulties maintaining focus. It is an urgent care issue facing elderly patients residing in nursing homes, or long-term care (LTC) facilities. Delirium is a significant cause of illness and mortality, affecting between 10%-89% of LTC patients, but little research has focused on delirium prevention in the LTC setting. This study will assess the effectiveness of a LTC multicomponent delirium prevention program (PREPARED Trial intervention). The PREPARED Trial intervention is an intervention provided to nursing staff working in LTC facilities that consists of four components: a decision tree, an instruction manual, a training package, and a toolkit. The feasibility and acceptability of the PREPARED Trial intervention has already been successfully demonstrated; however, a thorough and well-designed large scale study is needed in order to confirm its ability to reduce delirium among LTC residents. In this study, approximately 40-50 LTC facilities will be randomized to either receive the PREPARED Trial intervention or to receive usual care. At the end of the 4-year study period, the investigators will be able to demonstrate the degree to which the PREPARED Trial intervention reduces: 1) the number of new cases of delirium; 2) delirium severity; and 3) the duration of delirium episodes. This study will provide the blueprint of a program that can be transferable to LTC facilities across Canada.
