Filter by:The study uses the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework to assess the Carer Matters programme for dementia caregivers in Singapore. A parallel mixed-methods study design is applied to assess the programme's feasibility and effectiveness.
The purpose of this study is to test whether treatment-resistant late life depression is associated with declines in memory and attention and brain structure and function.
Idiopathic normal pressure hydrocephalus (INPH) is a treatable disease of the elderly, typically causing gait impariment, dementia and urinary incontinence. The objective of this study is to make an epidemiological survey of INPH in Umeå, Sweden. Subjects with self-perceived gait impairments will be identified through a questionnaire. They will go through clinical examinations and have an MRI of the brain. A control population will also be investigated to enable comparisons between the populations. The main hypothesis is that the prevalence of INPH in the population is higher than what is previoulsy known.
This research investigates the effect of active versus sham tACS paired with cognitive exercises in a regimen protocol of weeks, everyday. The study design is a one-time crossing over design in which participants are randomized into two groups: One group will receive active treatment for 4 weeks, then 8 weeks of no treatment followed by another 4 weeks of treatment but with sham. The other group will start with sham and end up with active treatment. The study is double-blind; thus, neither participants, nor the assessors know the group assignment. The Intervention is applying tACS either active or sham paired with cognitive exercises (MindTriggers app games). Note: The above study will run at both University of Manitoba (U of M) and Aster Gardens residence. However, at Aster Gardens Residence only questionnaire type of assessments will be run, while in U of M, the investigators will have three other major assessments as well. In addition, the investigators will run the assessments at the Aster Gardens Residence through online sessions.
There is a need for caregiver-initiated and -implemented non-pharmacological interventions directly to and for the person with dementia, including environmental assessment and modification, as first-line treatments for behavioral and psychological symptoms of dementia (BPSD) in persons living with dementia (PLWD). Delivered via telehealth, Harmony at HOME (H@H) aims to train caregivers of persons with moderate to severe ADRD in the skills of assessing and modifying the home environment to promote "person-environment fit," a concept that posits that the ability to access features within a built environment (e.g. bathroom, stairs,) or that factors within the environment itself (lighting, noise level, temperature), especially when linked with individualized social support, contribute to or even shape behavior. In addition to the intervention, the first 10 caregiver participants to enroll will also be invited to participate in two focus groups that will be facilitated during and after the intervention. The first focus group focuses on experiences as a dementia caregiver in rural areas. The second focus group focuses on providing feedback regarding caregivers' perceptions, acceptability, and usefulness of the H@H intervention. These focus groups will be conducted as structured interviews with open-ended questions that encourage participants to share their experiences.
Global dementia prevalence is rising. Alzheimer's disease (AD), the most common cause, has devastating effects on people's quality of life. AD has a preclinical (pre-AD) period of 10-20 years when brain pathology silently progresses before any cognitive symptoms appear. Current tests for pre-AD are invasive, costly and unsuitable for screening at population level. Similar to screening for pre-diabetes and carcinoma in situ, it is important to detect AD at the preclinical stage in order to offer early interventions before the pathology progresses to the irrerversible degenerative stage. In the study, research will develop a new scalable test (TAS Test) by combining two innovative ideas: hand-movement tests to detect pre-AD >10 years before cognitive symptoms begin; and computer vision so people can "self-test" online using home computers. This unique approach builds on recent discoveries that hand-movement patterns change in pre-AD. The research team will use exquisitely precise computer vision methods to automatically analyse movement data from thousands of participants, and combine this with machine learning of overall motor-cognitive performance. The project team has access to 3 well-phenotyped cohorts, >10,000 existing participants and a cutting-edge assay for a blood AD biomarker, ptau181. The research team will develop a TAS Test algorithm to classify hand-movement and cognitive test data for pre-AD risk (p-taua181 levels) and determine TAS Test's precision to prospectively predict 5-year risks of cognitive decline and AD.
Brain oscillations are ubiquitous in the human brain and have been implicated in cognitive and behavioral states defined in precisely tuned neural networks. In neurodegenerative disorders, neurodegeneration is accompanied by changes in oscillatory activity leading to the emerging concept of neurological and psychiatric disorders as "oscillopathies". Dementia with Lewy bodies (DLB), which is the second most frequent cause of neurodegenerative dementia, is characterized by an important alteration of brain oscillations. The restoration of oscillations by neuronal entrainment in animal models of neurodegenerative disease has shown a significant reduction in the neuropathological load of toxic proteins, with a consequent significant increase in cognitive performance. Transcranial alternating current brain stimulation (tACS), is a neurophysiological method of non-invasive modulation of the excitability of the central nervous system that is having an increasingly numerous spectrum of potential therapeutic applications. Recent studies have demonstrated the effectiveness of this method in modulating the natural frequencies of cerebral oscillation, underlying multiple cognitive processes such as verbal memory, perception and working memory. On the basis of these premises, the treatment with alpha tACS is proposed in patients with DLB. In this randomized, double-blind, sham-controlled, cross-over study, the investigators will evaluate whether a single stimulation with alpha tACS on the occipital lobes can improve symptoms in patients with DLB.
Alzheimer's disease (AD) may currently be diagnosed using molecular biomarkers in cerebrospinal fluid (CSF) and/or positron emission tomography (PET). These diagnostic procedures are highly accurate, but the high cost and low availability hamper their feasibility. Recently, ultrasensitive blood tests predicting Alzheimer pathologies in the brain have been developed. These tests have a reliable ability to differentiate AD from other neurodegenerative disorders and identify AD across the clinical continuum with high sensitivity and specificity in research cohorts with a high prevalence of AD. This project will assess the predictive value of these tests in a general practice population. The hypothesis is that the actual blood panel will have high positive predictive value for a diagnosis of Alzheimer's disease in the primary health care setting.
The purpose of this study is to test the adapted protocol, CAPABLE Family which builds upon the evidenced based CAPABLE program to address older adults with co-occurring physical disability and mild cognitive impairment or early stage dementia and the older adults' caregivers. It will consist of two phases - an open label pilot and waitlist control trial.
The main objective of this study is to evaluate the effect of periodontal therapy in in subjects with a clinical diagnosis of mild to moderate AD dementia.
