Filter by:Background: This pragmatic clinical trial aims to determine the efficacy and safety of add-on Astragalus for cognition and non- cognition in patients with of mild to moderate Alzheimer's disease complicated with orthostatic hypotension in orthostatic hypotension, elucidate the underlying mechanisms, identify related response predictors, and explore effective drug components. Methods: This is an add-on, assessor-blinded, parallel, pragmatic, randomized controlled trial. At least 66 adults with mild to moderate Alzheimer's disease (AD) and OH aged >30 years will be recruited. Participants will be randomized in a 1:1:1 ratio to receive 24 weeks of routine care or add-on low dose Astragalus or high dose Astragalus group. The primary efficacy outcome will be measured by the Alzheimer's Disease Assessment Scale-Cognitive Subscale, Chinese version. Secondary efficacy outcome assessment will include neuropsychological tests, blood pressure, plasma biomarkers, multimodal electroencephalograms, and neuroimaging. Safety outcome measures will include physical examinations, vital signs, electrocardiography, laboratory tests (such as hematologic and blood chemical tests), and adverse event records.
The primary purpose of the study is to evaluate the safety and tolerability of emraclidine administered orally to healthy elderly participants in Part A (multiple ascending doses) and participants with dementia due to Alzheimer's disease (AD) in Part B.
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". Alzheimer's disease, which accounts for the vast majority of age-related dementias, is characterised by a prominent disruption of oscillations in the gamma frequency band. The restoration of gamma oscillations by neural entrainment in animal models of Alzheimer's disease have shown a remarkable decrease in the pathological burden of amyloid and tau via increased microglial activity, resulting in a significant increase of cognitive performances. 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 gamma tACS is proposed in patients affected by Alzheimer's disease. In this randomized, double-blind, sham-controlled study, followed by an open-label phase, the investigators will evaluate whether a 9- or 18-weeks treatment with gamma tACS over the precuneus, delivered at home, can improve symptoms in patients with mild Alzheimer's disease.
Aim 1: Characterize shared decision-making and unmet patient-caregiver dyads needs for patients with diabetes and Alzheimer's Disease and related dementias (ADRD) while using a continuous glucose monitoring (CGM) device. Aim 2: Develop an interactive tool to enhance shared decision-making for diabetes management.
Phase 1 clinical trial of AV-1959 amyloid-β vaccine for Alzheimer's disease (AD).
Autobiographical memory is diminished in patients with Alzheimer's Disease and those with behavioral variant of frontotemporal dementia, and research has focused on the hampered ability of patients in retrieving specific memories. However, this study proposes a detailed methodology to provide a qualitative analysis of autobiographical specificity.
This study is an open-label, multi-center, non-randomized pivotal Phase 3 study to assess the efficacy and safety of PET imaging with [18F]PI-2620 for detection of tau deposition in subjects with Alzheimer's disease (AD) and controls during lifetime when compared to histopathology obtained after death and completion of brain autopsy.
This is a study on patient registry, and the sample size of this clinicaltrial is designed in group sequential design. According to the diagnostic criteria, the subjects are divided into SCD group, MCI group and mild dementia group. At the early stage of treatment, the investigators give participants transcutaneous electrical acupoint stimulation and music therapy according to the guidance of TCM syndrome differentiation. Participants can treat themselves at home after the investigators give them intelligent device and music，and according to the TCM syndrome score, neuropsychological scale, curative effect evaluation of daily life ability scale, determining the optimal comprehensive treatment plan,and phase in the treatment of participants with food, clothing, shelter, line, and life aspects of health education and guidance, a total of 24 weeks of treatment.
The main aim of the study is to characterize and understand the pathological mechanisms underlying the motoric cognitive risk syndrome, which is a predictor of Alzheimer disease.
This is a randomized, double-blind, sham-controlled, adaptive-design pivotal study of sensory stimulation in subjects with mild to moderate Alzheimer's disease. Approximately 530 subjects will be randomized to 12 months of daily treatment with either Active or Sham Sensory Stimulation Systems. Efficacy will be measured using the Alzheimer's Disease Cooperative Study- Activities of Daily Living (ADCS-ADL) assessment and a combined statistical test (CST) of the ADCS-ADL and the Mini-Mental State Exam (MMSE).
