Filter by:This study will use an anticholinergic pharmacological probe to examine attention network function in SCD using EEG. The overall hypothesis is that in older adults with SCD, normal cognitive performance is maintained by compensatory attention network activity, supported by enhanced cholinergic function. The investigators anticipate that SCD will be associated with greater compensatory attention network activity and that disrupting this compensatory process through anticholinergic challenge will result in a greater negative effect on attentional performance (Attention Network Test, ANT) and attention network functioning (EEG) in older adults with greater subjective cognitive concern.
The goal of this observational study is to compare cerebral perfusion patterns with pseudo-continuous arterial spin labeling (pCASL) and brain metabolism patterns with fluorodeoxyglucose-position emission tomography (FDG-PET) in patients with mild cognitive impairment (MCI) and subjective cognitive decline (SCD). The main questions it aims to answer are: - Do pCASL sequences identify hypoperfusion patterns that correlate well with FDG-PET hypometabolic patterns? - Are there differences in this correlation in terms of cerebrospinal fluid (CSF) profiles? - Can hypoperfusion patterns in pCASL predict conversion to dementia? Participants will undergo brain 3 Tesla magnetic resonance imaging (MRI), FDG-PET, lumbal puncture and blood collection to analyze amyloid beta and tau, yearly detailed neuropsychological tests for three years.
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.
This study aims to establish the Senior Driving Simulation Training (SDST) for Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI), and explore the effectiveness of Senior Driving Simulation Training (SDST) on the executive function, cognitive function and EEG.
The purpose of this study is to determine if intensive lowering of systolic blood pressure (SBP), using FDA approved medications (antihypertensive), reduces Alzheimer's Disease pathology (i.e., excessive brain amyloid and tau protein deposition) in older adults at high risk for memory decline or dementia.
This study aims to (1) determine the intervention effects of sequential and simultaneous training on cognitive function and health-related function for cognitively-normal elderly and elderly with Mild Cognitive Impairment(MCI) and Subjective Cognitive Decline(SCD); (2) compare which combination approach is more advantageous for improvement on outcome measures.
Some patients with subjective cognitive decline (SCD) progress to neurocognitive disorders (NCD), whereas others remain stable; however, the neuropsychological determinants of this progression have not been identified. The investigators objective was to examine baseline neuropsychological indicators that could discriminate between people in whom the SCD progressed to a mild or major NCD and people in whom the SCD remained stable. The investigators retrospectively included patients consulting for SCD at a university medical center's memory center (Amiens, France) and who had undergone three or more neuropsychological assessments at least 6 months apart. The relationship between domain-specific scores and the global cognitive score (GCS, as a function of final status (stable SCD vs. progression toward a mild or major NCD)) was examined using a generalized linear mixed model.
More than 4.4 million patients receive home health services following discharge from the hospital or rehabilitation facility. A substantial number (70%) are older adults with subjective cognitive decline (SCD), an early clinical sign of Alzheimer's disease and related dementia. SCD is associated with diminished activity performance, poor quality-of-life and other adverse health outcomes (e.g., depressive symptoms). Home health patients with SCD often require more time, structure, and guidance to complete tasks and adjust to new skills and environments. Support is especially important during this high-risk period of transition between care settings. We propose a new home health care delivery model in partnership with Kindred at Home (KAH), a division of Humana that encompasses 400 programs across 40 states. DEMA-Pro builds on five preliminary studies that demonstrated high feasibility, acceptability, and positive preliminary effects on health outcomes (physical function, mood, and QoL). DEMA-Pro will be refined for delivery by home health services staff to patients with SCD and their informal caregivers. The overall goal of this research will be to conduct a pragmatic cluster randomized controlled trial (RCT) of DEMA-Pro to improve outcomes in-home health service patients with SCD. In the current R61 pilot phase, we will establish the trial's organizational structure and processes and pilot test DEMA-Pro in 4 home health services sites. In a subsequent trial, we plan to conduct a full pragmatic RCT in a group of Kindred KAH sites comparing DEMA-Pro to usual care. Consistent with the spirit of a pragmatic trial, we will use existing data sources including electronic Medicare OASIS (Outcome and Assessment Information Set) data, and QoL to characterize the cohort and measure outcomes. Thus, the focus of the pilot phase will be to ensure all processes are in place to conduct the subsequent RCT. Aim 1. Establish the organizational infrastructure and programmatic processes needed to conduct a pragmatic cluster-randomized control trial of the DEMA-Pro intervention versus usual care. A Steering Committee will lead the project and coordinate the activities of 3 Work Groups: Regulatory and Operations; DEMA-Pro Intervention Protocol; and Data Management and Analysis. Aim 2. Pilot test the DEMA-Pro training protocol in 4 KAH North Region locations and refine as indicated.

Subjective cognitive decline (SCD) is receiving increasing attention as a risk factor for incident dementia due to AD. SCD manifests prior to the onset of clinical impairment, and as such could serve as a potential target population for early intervention trials. The pathogenesis of AD is complex and involves a dysregulation of the neuroendocrine immune (NEI) system, a network of signaling molecules, such as neurotransmitters, hormones and cytokines. As a result, it may be unlikely that cognitive decline may be mitigated by drugs acting on a single specific target. Plant extracts acting at different levels of the NEI regulation could represent appealing therapeutic strategies for cognitive decline. Citrus-derived phytochemicals, like auraptene and naringenin, showed antioxidant, anti-inflammatory, and neuroprotective effects in preclinical studies of AD mouse models and preservation of cognition in elderly without cognitive impairment. This is a pilot randomized controlled trial to determine clinical and biological effects of Citrus-phytochemicals in individuals with SCD. Participants will be randomized to receive Citrus-phytochemicals standardized in auraptene and naringenin or placebo for 9 months. Cognitive tests and blood-based biological markers will be done at baseline and at the end of treatment as outcome measures.
