NCT07279103
This study aims to examine the effects of a multisensory environment-based occupational therapy intervention on sensory processing, cognitive status, behavioral and psychological symptoms, and caregiver burden in individuals diagnosed with Alzheimer's disease. Non-pharmacological approaches in Alzheimer's management have been shown to slow functional decline, reduce behavioral symptoms, and improve caregivers' well-being. Multisensory environments provide visual, auditory, tactile, proprioceptive, vestibular, olfactory, and gustatory stimuli to support sensory integration and enhance engagement, particularly in individuals with cognitive and communication difficulties. The study will be conducted using a randomized controlled design and will include individuals aged 65 years and older with moderate-stage Alzheimer's disease and their primary caregivers. The intervention will be implemented over four weeks with two sessions per week. Outcome measures will include the Adult/Adolescent Sensory Profile,Loewenstein Occupational Therapy Cognitive Assessment-Geriatric version, Neuropsychiatric Inventory, and Zarit Caregiver Burden Inventory. The study is expected to contribute to the evidence base supporting sensory-based occupational therapy interventions in dementia care.
NCT04404153
The prevalence of Alzheimer's Disease (AD) is rising, but existing medications provide only modest control of cognitive decline and associated symptoms, and novel therapies are urgently needed. This randomized sham-controlled trial will determine if an innovative low-risk remotely-supervised transcranial Direct Current Stimulation (tDCS) applied over the area of the dorsolateral prefrontal cortex for 30 minutes at the intensity of 2 mA five times per week for 6 months at home can improve cognitive performance and symptoms and modulate neuroimaging markers of neuroplasticity in 100 patients with mild to moderate AD. If effective, this novel intervention can substantially enhance AD symptom management at home, improve quality of life of AD patients and their families, and reduce burden associated with this debilitating illness.
NCT07284290
The proposed study aims to address the critical gaps in understanding the mechanisms of CF (Cognitive Fluctuations) by leveraging recently emerged molecular biomarkers, advanced neuroimaging techniques to assess measures of cholinergic degeneration, and synchronous EEG and assessments of attention. One of the overarching innovations of study is combining all of these assessments into one integrated research plan
NCT07083154
The LIGHT-COG study is a 76-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial. A total of 420 type 2 diabetes patients with early dementia are randomized 1:1 to either the active treatment group (receiving subcutaneous injections of mazdutide weekly, with stepwise dose escalation to a maintenance dose per protocol) or the placebo group (receiving matched placebo injections). The primary objective is to evaluate the potential disease-modifying effects of mazdutide on cognitive dysfunction in type 2 diabetes.
NCT06416371
The goal of this observational study is to learn about leakage from retinal vessels in cerebral small vessel disease. The main questions it aims to answer are: * Does retinal vessel leakage occur in cerebral small vessel disease? * If it does, is the severity of retinal vessel leakage similar to the severity of cerebral small vessel disease generally? Participants will be tested using fluorescein angiography. This involves an intravenous injection of fluorescent dye, and is a very sensitive way to find leakage from retinal blood vessels. Participants will have already had brain scans and other examinations and tests to measure the severity of their cerebral small vessel disease. Our new retinal images will complement the information from these previous tests.
NCT01767311
This is a multinational, multicenter, double-blind, placebo-controlled, parallel-group study using a Bayesian design with response adaptive randomization across placebo or 5 active arms of lecanemab to determine clinical efficacy and to explore the dose response of lecanemab using a composite clinical score (ADCOMS). BAN2401-G000-201 Core study is an 18-month study in which 3 dose levels (2.5, 5, and 10 mg/kg) are given biweekly (once every 2 weeks) to separate groups of participants and 2 dose levels (5 and 10 mg/kg) are given monthly (once every 4 weeks) to separate groups of participants. Participants will be from 2 clinical subgroups: mild cognitive impairment (MCI) due to Alzheimer's disease (AD) or mild Alzheimer's disease dementia. Frequent interim analyses will be conducted to continually update randomization allocation on the basis of the primary clinical endpoint. Any participant who completes the study treatment (Visit 42 \[Week 79\] of the Core study) or discontinues the Core Study will be eligible to participate in the Extension Phase, provided they meet the Extension Phase inclusion and exclusion criteria. Participants will receive 10 mg/kg biweekly for up to 60 months or until the drug is commercially available in the country, where the subject resides, or until the benefit-to-risk ratio from treatment with lecanemab is no longer considered favorable, whichever comes first. The Follow-up Visit in the Extension Phase will take place 3 months after the last dose of study drug.
NCT03881579
Currently almost 5 million Americans suffer from the distressing symptoms related to dementia and this number that will triple by 2050. The overall goals of the proposed project are to evaluate, in community dwelling Alzheimer's Disease Research Center participants the benefits of a 12-month nurse-led early palliative intervention on symptoms, quality of life, health care resource use. The relevance of this research to public health is that there is an urgent need to improve the palliative care of persons with dementia living in the community. This study will contribute substantially to that effort.
NCT07444554
The goal of this clinical trial is to learn whether a 12-week high-velocity resistance training program can improve brain blood flow and thinking skills in adults ages 60 to 79 who are at higher risk for Alzheimer's disease and related dementias. Researchers want to understand whether this type of exercise can improve how well the brain regulates blood flow during mental and physical tasks and whether those changes are linked to improvements in thinking ability. The main questions this study aims to answer are whether high-velocity resistance training improves thinking skills such as executive function and processing speed, and whether it improves how blood flow in the brain responds during cognitive testing, changes in blood pressure, and controlled breathing tasks. Participants will complete two study visits at the University of Illinois Chicago, one before the program begins and one after 12 weeks. During these visits, researchers will measure strength, muscle power, and thinking skills. Participants will also complete non-invasive testing to measure blood flow in the brain using ultrasound. During some tasks, participants will walk on a treadmill at a comfortable pace while completing thinking tests. They will wear small sensors to measure heart rate, blood pressure, and breathing. After the first visit, participants will be randomly assigned, like flipping a coin, to one of two groups. One group will take part in supervised resistance training three times per week for 12 weeks at the University of Illinois Chicago. Each session will last about 60 minutes and will be supervised by trained exercise professionals. The other group will continue their usual daily activities for 12 weeks and then return for follow-up testing. Participants in the comparison group will be offered the exercise program after they complete the final study visit. Researchers hope this study will improve understanding of how structured exercise may support brain health in older adults at risk for dementia and help guide future prevention strategies.
NCT06484244
In people with Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD), reduced capacity for locomotor adaptation is a fundamental but poorly understood mechanism that can be a sensitive biomarker of cognitive-motor impairments. It is also an important therapeutic target for exercise-based interventions to improve walking function. The overall goal of this study is to understand the effects of MCI and AD on locomotor adaptation and walking function.
NCT07443566
This study is a 10-year follow-up of a previously enrolled cohort of patients who underwent surgery for acute hip fracture with spinal anesthesia and had pre-fracture cognitive status assessed (Clinical Dementia Rating, CDR) and cerebrospinal fluid (CSF) biomarkers related to Alzheimer's disease measured (e.g., Aβ42/Aβ40 ratio, total tau, phosphorylated tau). The primary aim is to determine long-term survival at 10 years after index hip fracture surgery and to evaluate whether baseline cognitive status and/or Alzheimer-type CSF biomarker profiles are associated with long-term mortality.
NCT06029894
The purpose of this research is to learn whether a dietary citicoline supplement will impact sleep and cognition. Cognitive disorders include such things as memory disorders and mild cognitive impairment. The investigators are studying persons with mild cognitive impairment (MCI). For this population, the team will assess whether citicoline also impacts biomarkers, a marker of the patient's biological state, in their body. The investigators are interested in learning more about a dietary supplement called citicoline and how it helps sleep, cognition, and markers of Alzheimer's. Previous studies have evaluated this dietary supplement and shown that citicoline may impact cognitive decline. The investigator would like to evaluate if citicoline will also impact sleep and markers of Alzheimer's. This dietary supplement has been assessed in older adults and found to be well tolerated. Citicoline has been used safely in cognitive impairment populations at the same dosage.
NCT07435467
The BAD-GER study is a multicenter, prospective, three-arm observational study serving to validate a prognostic biomarker algorithm for mortality and hospital readmission; this algorithm will be developed through the retrospective analysis of Alzheimer's Disease and neurodegeneration biomarkers in an already available discovery cohort of 700 previously hospitalized geriatric patients.
NCT05978804
The primary objective of this research is to evaluate the effects of non-invasive brain stimulation and computerized cognitive training on executive functioning in individuals with Primary Progressive Aphasia (PPA), mild cognitive impairment (MCI), or dementia. In this study, investigators will use transcranial direct current stimulation (tDCS) to stimulate the left dorsolateral prefrontal cortex (DLPFC). Previous studies have demonstrated that tDCS over the DLPFC led to improvements in attention deficit caused by stroke, Parkinson's Disease, and major depression as well as language deficits caused by neurodegenerative conditions such as primary progressive aphasia or mild cognitive impairment. The investigators seek to expand on this literature by investigating how anodal tDCS paired with and without cognitive training will impact executive functioning in PPA with Frontotemporal Dementia or Alzheimer's Disease pathology and Mild Cognitive Impairment/Alzheimer's Disease (e.g. shifting, updating, monitoring, and manipulation).
NCT04863495
This is a longitudinal study with regular quantitative assessments of all participants every six months for 3 years. The quantitative portion of the study will recruit couples, consisting of individuals over the age of 65 who are in a committed relationship. Both members of the couple must be willing to participate at baseline. The assessment is in two parts. In the first part, each member of the couple will be asked the following: demographic information, mental health history, self-reported physical and emotional health, measures of emotional and mental health, personality, relationship and attachment style, social support and self-efficacy. Then each member of the study couple will be asked a series of questions to determine whether they consider themselves a caregiver. If they do, individuals will be asked to respond to additional caregiver questionnaires. Follow-ups will occur every six months for the study couples for a total of three years from the baseline visit. Each visit, the entire assessment except for demographic questions, will be re-administered to each individual in the couple. At the end of each questionnaire battery, individuals will be screened for cognitive impairment and those who are in the middle to advanced stages of dementia will no longer participate. Recruitment will end when 600 individuals (300 couples,150 couples at each site) are enrolled in the longitudinal portion of the study. All study visits will be conducted virtually via Zoom or WebEx video conferencing. Analyses will be conducted to determine the association between changes in dyadic relationship and changes in mental health and cognitive outcomes, to elucidate how relationship characteristics impact health and well-being as perceived by each member of the dyad.
NCT05522387
The goal of this Phase 2 Open Label study is to evaluate long-term safety, tolerability, and efficacy of XPro1595 on measures of cognition, function and brain quality in individuals with Alzheimer's Disease.
NCT01800214
The prospect of disease-modifying therapies in the pipeline for Alzheimer's Disease (AD) has intensified efforts to use brain imaging more effectively for diagnosis and monitoring of dementing illnesses. There is also emerging awareness of the destructive interplay between AD and Cerebrovascular Disease (CVD) in our aging population; both disorders share common vascular risk factors and may respond to similar prevention treatments. Brain mapping techniques capitalize on the fact that different neurodegenerative diseases target particular brain areas. Brain shrinkage and stroke disease can be quantified on Magnetic Resonance Imaging (MRI) using computerized analysis. This ongoing study applies advanced MR imaging analysis, genetic testing and standardized cognitive and functional assessments done at yearly intervals to measure and monitor longitudinal change in patients with AD, vascular and other neurodegenerative diseases and potentially to measure modifying effects of emerging therapies. Nearly 1800 patients (Mild Cognitive Impairment or dementia from AD, Vascular, Frontotemporal or Lewy Body Disease) and over 140 normal elderly have already been enrolled, with 180 autopsies. This study utilizes specialized imaging analysis software packages to reliably quantify brain tissue volumes and small vessel disease, the most common type of CVD. The SDS also investigates other potential biomarkers of dementia such as eye-tracking, optical coherence tomography, gait and balance, and the gut microbiome to explore their clinical utility. Results from this study will help to improve diagnosis, to customize treatment, and to better monitor disease-modifying therapies currently under investigation should they become applicable to everyday practice.
NCT07419022
Older adults and their care partners will participate in music therapy sessions for approximately 8 weeks. Before and after the 8 week study period, participants will fill out questionnaires about their mood, stress levels, and emotions. During the music therapy sessions, they may be observed or asked questions about the music therapy sessions.
NCT07314190
This is a retrospective observational study to evaluate the clinical utility of blood-based biomarkers in the diagnosis and management of patients with a neurodegenerative disease (ND) or mental disorder (MD).
NCT06223360
The purpose of this study is to learn more about the safety, effectiveness and tolerability of the study drug called Benfotiamine which may delay or slow the progression of the symptoms of early Alzheimer's disease.
NCT05858996
There are evidence based processes for assessment and management of pain using pharmacologic and nonpharmacological approaches. These were reviewed and included within the Pain Management Clinical Practice Guideline (Pain Management CPG) recently developed by AMDA: The Society for Post-Acute and Long-Term Care Medicine. There are, however, many challenges to translating the use of Clinical Practice Guidelines into clinical settings. To overcome these challenges we developed and previously tested a theoretically based approach and merged this approach with the Pain Management CPG, which is referred to as the PAIN-CLINICAL PRACTICE GUIDELINE-USING THE EVIDENCE INTEGRATION TRIANGLE (PAIN-CPG-EIT). The PAIN-CPG-EIT involves a research nurse facilitator working with an identified community champion(s) and stakeholder team for 12 months to provide the following four components: Component I: Establishing and meeting monthly with a Stakeholder Team; Component II: Education of the staff; Component III: Mentoring and motivating the staff to address pain; Component IV: Ongoing evaluation of resident pain outcomes. Twelve communities will be included with 25 residents living with dementia and pain recruited from each community. Six communities will be randomized to treatment (PAIN-CPG-EIT) and six randomized to education only (EO) which involves providing the same education to staff as is done in Component II of PAIN-CPG-EIT. The primary aim of this study is to test the effectiveness of use of the PAIN-CPG-EIT to improve the assessment, diagnosis and management of pain and decrease pain intensity among nursing home residents living with dementia between baseline, 4 and 12 months and evaluate treatment fidelity. A secondary aim of the study is to consider differences in measurement, treatment and response to treatment between male and female and Black versus White residents living with dementia. Findings from this study will help build on the currently limited information about pain presentation and management among older adults living with dementia in nursing homes and improve health equity of aging populations experiencing pain.
