Filter by:The GOIZ ZAINDU Gipuzkoa - GO - ON Study is an intervention trial to evaluate the efficacy of dementia prevention strategies in cognitively frail people. It is a large-scale randomized controlled trial in over 1000 older adults between 60 and 85 years old with increased CAIDE risk score (≥6), non-demented but with low performance in at least one of three brief cognitive tests. Participants will be randomized to receive standard health advice (SHA-control) or a multidomain intervention (MM-Int) consisting of 1) Risk factor control (vascular factors, polypharmacy); 2) Cognitive training, 3) Physical activity, 4) Dietary changing program, and 5) emotional counseling and social engagement. The primary aim is to demonstrate a 20% reduction in the proportion of subjects who decline in their NTB performance (z score) after 24 months in the intervention group compared to the controls. Secondary aims include: 1) Analyze cost-effectiveness; 2) Show a beneficial effect of the intervention on functional abilities, quality of life, and depressive and anxiety symptoms; 3) Investigate the impact of a lifestyle intervention on aging. In this sense, biological samples and neuroimaging studies will be collected to allow exploratory investigations on aging mechanisms, amyloid imbalance, tau pathology, epigenetics, neuroinflammation, vascular dysfunction, lipid dysregulation, white matter disintegration, cognitive and brain reserve. This protocol is participant-centered, empowering citizens since the recruitment process to gain access to knowledge about their dementia risk status via web or by phone and then decide to participate. Intervention activities have also taken into account participants' perspective with the design of easy-to-use and appealing activities (e.g., using a self-administered at-home physical activity program such as VIVIFRAIL© and EXERCITA© cognitive training materials that have been developed, taking into account the Basque Country population's cultural, linguistic and educational particularities; and diet and nutritional workshops with famous chefs to learn innovative and attractive healthy recipes). The GO-ON trial may shed light on the tools that people need to fulfill the expectation of an active, healthy dementia-free aging. These include digital tools that in the COVID19 pandemic have shown to be effective in removing distance barriers. GO-ON uses them to give support and expand the possibilities to clinical assessment settings and intervention delivery. The digital part of the intervention may expand preventive actions to small rural areas, including digital socialization. GO-ON Study, which starts in summer 2021, is the first large-scale lifestyle intervention trial in Southern Europe that takes part in the WORLDWIDE FINGERs network and will help answer whether the FINGER results can be replicated. The intervention design has been made on the basis that if proven to be efficacious, it may be easily applied at a Public System-level to guarantee a rapid and easy translation of research results to Primary Care settings and people homes.
When dementia is caused by AD, we refer to it as dementia of the Alzheimer's Type (DAT). The greatest risk factor for Alzheimer's Disease (AD) and DAT is advancing age, but DAT is not a normal part of aging. Studies have shown that changes in the brain happen before full symptoms of DAT develop. These changes include a buildup of two proteins within the brain, called amyloid and tau. The two goals of this study are (1) to determine whether patients with mild cognitive impairment or dementia-Alzheimer's type (DAT) are able to demonstrate decisional capacity to engage in PET amyloid and tau disclosure after receiving education; and (2) to assess how patients and care partners react to PET amyloid and tau biomarker disclosure.
This study is being done to evaluate the safety and feasibility of using Dasatinib and Quercetin together in subjects with Mild Cognitive Impairment (MCI) or Alzheimer's disease.
The present randomized controlled trial has the main objective to study the effects of a videoconferenced occupational therapy program in preventing cancer and chemotherapy-related cognitive impairment and other health outcomes, as well as in improving quality of live and occupational performance of women undergoing chemotherapy for breast cancer.
The study is carried out as part of the GR2021 Priority project "Healthy Brains for life (Age 20-99): Digitally-enhanced personalized medicine study ANANEOS" and code numbered GR-00546 and it will look at the decentralized and remote assessment of the symptoms of preclinical stages in Alzheimer's disease and movement disorders, e.g. Parkinson's. For this study we are looking for participants aged over 45 without cognitive complaints or with subjective perception of cognitive decline or with mild cognitive complaints. Specific aims for the proposed study: a) to develop novel sensitive measures that can provide an early identification of those SCD and MCI individuals harboring AD pathology that are at high risk of cognitive worsening over time; b) to track pre-motor stages in Parkinson's disease and trials that enable active digital functional biomarkers; c) to track disease progression during pre-dementia and pre-motor stages in clinical practice and trials with measures that enable to capture subtle changes.
This study is being performed to determine if a multi-ingredient dietary supplement is safe and easy to take by healthy older adults. Participants will be required to take one of three different doses of the dietary supplement for 90 consecutive days and complete wellness surveys and a daily log while taking the supplement. Participants will also provide blood samples at the start of the study, after 30 days, and at the end of the study which will help determine how participants respond to the supplement.
Patients from 60 to 75 years old diagnosed with cerebral small vessel disease with no history of symptomatic stroke, brain tumor, traumatic brain injury, seizures and neurodegenerative or mental disorder will undergo overnight leg actigraphy and cardiorespiratory monitoring. Those of them with apnea/hypopnea index under 5 will be enrolled. Brain MRI and cognitive assessment will be performed at baseline and in 1-year follow-up, sleep quality will be assessed at baseline with self-reported questionnaires. Progression of cerebral small vessel disease markers and cognitive dysfunction will be compared between patients with high periodic limb movement index (the number of periodic limb movement ≥ 15 per hour of sleep) and controls (periodic limb movement index < 15/h).
This study will characterize tau tracer retention by Positron Emission Tomography (PET) as a function of amyloid levels transversally and longitudinally.
The investigators will aim enroll participants into our study within 3-6 months after their parent study visit so the investigators can utilize some key data points (e.g. PD-MCI diagnosis, rs-fcMRI data) from that study. PD participants will participate in a single-blind RCT with two treatment arms: process training and strategy training (Fig 4). They will complete pre-training assessment (Pre), be randomized to treatment arm (1:1 ratio stratified by sex), and then complete 8 training sessions over an 8-week period. They will return within 1 week for post-training assessment (Post) and then will complete Follow-up (FU) assessments via web or mailed survey 3 and 6 months after training ends. They will complete a 12mo FU assessment in person in conjunction with their annual parent study visit. HC participants will complete prospective memory assessment at one time point coinciding with (or within 3-6 months of) their parent study visit to determine whether any relationships observed between rs-fcMRI data and prospective memory are specific to PD.
The goal of this study is to explore the effects of transcutaneous vagus nerve stimulation(tVNS) on improving cognition in community-dwelling elderly people. The study will recruit 120 subjects. Participants will undergo baseline cognitive assessment, EEG and eye tracking. Participants will be randomized to tVNS group and sham group. All subjects will repeat the baseline assessments after 1st session, 5th session，10th session and within 3 days after 10th session.
