NCT ID: NCT05655195 Recruiting - Alzheimer Disease Clinical Trials

Chronic Treatment of Alzheimer's Disease by Gamma Light and Sound Therapy

Start date: December 14, 2022
Phase: N/A
Study type: Interventional

Alzheimer's disease (AD) is characterized by significant memory loss, toxic protein deposits amyloid and tau) in the brain, and changes in the gamma frequency band on EEG. The investigator's lab found that boosting gamma waves in AD mouse models using light and sound stimulation at 40Hz not only reduced amyloid and tau in the brain, but also improved memory. The investigators developed a light and sound device for humans that stimulates the brain at 40Hz that can be used safely at home. For the present study, 60 participants with mild Alzheimer's disease will be enrolled and will use this light and sound device at-home daily for 6-months. Investigators will measure changes in brain waves with EEG, blood biomarkers, the microbiome via fecal samples, functional and structural MRI scans, memory and cognitive testing, and questionnaires at 3 in-person visits throughout the study. After the 6-month time point, participants will have the option of continuing in the study for one additional year and completing an 18-month study visit. This study will provide critical insight into extended therapy involving non-invasive 40Hz sensory stimulation as a possible therapeutic strategy for mild to moderate Alzheimer's disease.

Explore the Sharing Model Intervene to Improve the Knowledge, Attitudes, Service Intentions and Service Start-up Effects of the Eight Major Non-cancer Disease End-stage Caregivers on Well-being and Palliative Care

Start date: September 14, 2021
Phase: N/A
Study type: Interventional

Since September 1st, 2009, Taiwan has begun to pay attention to the care of patients with organ failure, dementia and the elderly, and brought eight of non-cancer terminal patients into health insurance subsidies to implement the goal of universal palliative care and local aging. Taiwan has entered the aged society since March 2018, become the heavy burden of expenditure in Taiwan because of the health care needs and costs associated with the rapid aging of the population. With advanced medical technology, when facing inevitable death situation, should not use too much medical treatment on terminally ill patients. The waste of medical resources and bring both patients and family members so much pain. In Taiwan, people have misconception about tranquil palliative care. The low rate of home palliative care for non-terminal cancer patients. The purpose of this study is investigating the eight non-cancer terminal caregivers' knowledge, attitudes and service intentions of palliative care, and getting the result by research intervention. In this study, a randomized experimental research design was applied by two-group pre-and post-test. The targets are the eight non-cancer terminal caregivers in a home care institution of a regional teaching hospital located in Yilan. Targets' ID end with odd numbers are in experimental group received shared mode intervention, and even numbers are in control group received home routine care. The experimental group was implementing measures of weekly shared mode intervention in 20 to 60 minutes for six weeks; the control group started to implement measures of home care medical instructions booklet in the third week. The content of the outcome measurement questionnaire includes: basic information of the eight non-cancer terminal caregivers, the palliative care knowledge scale, the palliative care attitude scale, and palliative care service initiation intention scale. Data were analyzed by statistical methods such as descriptive analysis, independent sample t-test, paired-samples t-test, Pearson correlation analysis and one-way ANOVA.

Tdap and Biomarkers of Alzheimer's Disease

Start date: May 1, 2023
Phase: Phase 1/Phase 2
Study type: Interventional

Recently, the Tdap (tetanus toxoid, reduced diphtheria toxoid and acellular pertussis) vaccination was added to the list of immunizations associated with lower incidence of dementia. Plasma-based biomarkers for AD are a welcome alternative to expensive and invasive testing for Alzheimer's; these biomarkers include assessment of amyloid and tau and neurofilament light protein that assesses non-specific neurodegeneration. The investigators will test for these biomarkers, as well as some immune parameters, administer Tdap then repeat the blood tests in six months.

NCT ID: NCT05138848 Recruiting - Clinical trials for Mild Cognitive Impairment

Time-in-bed Restriction in Older Adults With Sleep Difficulties With and Without Risk for Alzheimer's Disease

ALPS
Start date: January 3, 2022
Phase: N/A
Study type: Interventional

Dementia caused by Alzheimer's disease affects approximately 5.6 million adults over age 65, with costs expected to rise from $307 billion to $1.5 trillion over the next 30 years. Behavioral interventions have shown promise for mitigating neurodegeneration and cognitive impairments. Sleep is a modifiable health behavior that is critical for cognition and deteriorates with advancing age and Alzheimer's disease. Thus, it is a priority to examine whether improving sleep modifies Alzheimer's disease pathophysiology and cognitive function. Extant research suggests that deeper, more consolidated sleep is positively associated with memory and executive functions and networks that underlie these processes. Preliminary studies confirm that time-in-bed restriction interventions increase sleep efficiency and non-rapid eye movement slow-wave activity (SWA) and suggest that increases in SWA are associated with improved cognitive function. SWA reflects synaptic downscaling predominantly among prefrontal connections. Downscaling of prefrontal connections with the hippocampus during sleep may help to preserve the long-range connections that support memory and cognitive function. In pre-clinical Alzheimer's disease, hyperactivation of the hippocampus is thought to be excitotoxic and is shown to leave neurons vulnerable to further amyloid deposition. Synaptic downscaling through SWA may mitigate the progression of Alzheimer's disease through these pathways. The proposed study will behaviorally increase sleep depth (SWA) through four weeks of time-in-bed restriction in older adults characterized on amyloid deposition and multiple factors associated with Alzheimer's disease risk. This study will examine whether behaviorally enhanced SWA reduces hippocampal hyperactivation, leading to improved task-related prefrontal-hippocampal connectivity, plasma amyloid levels, and cognitive function. This research addresses whether a simple, feasible, and scalable behavioral sleep intervention improves functional neuroimaging indices of excitotoxicity, Alzheimer's pathophysiology, and cognitive performance.

NCT ID: NCT04449926 Completed - Clinical trials for Alzheimer Disease, Late Onset

BCG and Plasma Amyloid in Non-Demented Adults

Start date: November 9, 2020
Phase: Phase 2
Study type: Interventional

BCG vaccination, the most widely used vaccination in the world, is used to reduce risk of tuberculosis infection; it is used for other mycobacterial infections as well, benefiting leprosy and Buruli ulcer. BCG has "heterologous" effects that aids in an array of non-mycobacterial and viral infections as well as bladder cancer. It is the heterologous effect, sometimes called the "off-target" effect that may offer benefit in Alzheimer's disease. Population studies and studies of adults receiving BCG show a lessened risk of Alzheimer's disease. The study will see if BCG vaccination will alter a plasma test for amyloid, a biomarker for cerebral amyloid.
