Filter by: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 purpose of this open label study is to evaluate longer term tolerability and early efficacy of transcranial ultrasound in the treatment of patients with mild cognitive impairment or dementia.
Compensatory aids (e.g., alarms, calendars) play an important supporting role when completing everyday tasks (e.g., appointments, medication management), and there is a growing body of scientific work suggesting that compensatory training improves daily functioning. However, traditional paper-based calendars and to-do-lists have limitations related to accumulation of information, difficulty retrieving information, and remembering to complete activities. Such limitations may be overcome using a digital format through organized digital files, search functions, and alarms. This pilot project proposes to train older adults at risk for cognitive decline to use the Digital Memory Notebook (DMN), a tablet-based application (app), to support everyday functioning. The primary goal is to obtain preliminary evidence that a 6-week, individual and group-based DMN training intervention results in demonstrable changes in target behaviors (e.g., goal-directed DMN use to support everyday activities) among older adults with mild cognitive impairment (MCI) and subjective cognitive complaints (SCC). Participants will complete a curriculum involving 2-hour weekly sessions for 6-weeks. Each week will cover a specific function of the DMN and will include standardized goal-setting and weekly homework targets. Following the 6-week intervention, participants will continue to use the DMN app for 4-weeks to evaluate stability. Participants will complete a questionnaire packet 1 week prior to the 6-week intervention, 1 week after the 6-week intervention, and 5 weeks following the 6-week intervention. MCI and SCC participants will complete separate 6-week individual or group interventions spaced two months apart at UCD.
This goal of this study is to explore the effects of transcranial alternating current stimulation(tACS) combined with computerized cognitive training(CCT) on improving cognition for patients with mild cognitive impairment(MCI). The study will recruit 195 patients with MCI. Participants will undergo baseline cognitve assessment, EEG and structural and functional MRI. Participants will be randomized to active tACS+CCT group, sham tACS+CCT group and active tACS+sham CCT group. At the end of the intervention, 3-month, 6-month and 12-month follow-up, all subjects will repeat the baseline assessments.
The study intends to measure the evolution over time of the cognitive capacity of patients undergoing cataract surgery in relation to the opaque lens removal surgery (cataract) in a population considered to be at risk of neurocognitive degeneration. Secondary objectives: • Estimate the incidence of postoperative cognitive dysfunctions and any episodes of perioperative delirium with the aim of demonstrating the safety of cataract surgery in the elderly patient in terms of cognitive functions and impact on the psychological state. In the context of the study a risk sub-population analysis will be carried out, evaluating the trend over time of the "endothelial cells count" parameter The elderly population remains, due to the aging of the cornea, a population "at risk" for significant alterations from the clinical point of view. During the study the endothelial cells count will be monitored, in order to be able to evaluate the safety of the cataract surgery and to be able to correctly correlate a possible deterioration in the visual acuity of patients with corneal decompensation. To evaluate the progress of the endothelial cells count in the elderly patient during the pre-intervention and post-intervention period. Since the low values of cellular media in endothelial microscopy are an element that increases the risk of complications during cataract surgery, the study wants to assess how waiting times between filter visits and cataract surgery can cause an elderly patient worsening of this parameter even in a few months. The trend of the same parameter will be monitored even after the intervention since in case of decrease, the low endothelial count could cause an alteration of visual acuity and therefore a minor improvement in cognitive performance. The research will be set as a longitudinal observational study where will be compared in each patient the parameters analyzed in the 6 months prior to cataract surgery and in the 3 months following the operation itself. Patients will be enrolled during the first cataract filter visit, will be submitted to simple questions and their clinical data will be collected. Subsequently, before and after three months of surgery repeated cognitive testing and the control normally performed instrumental tests during follow-up. A clinical follow-up will be provided, during normal follow-up visits at 20 days and 6 months after the patient's surgery: the following information will be collected during these visits - BCVA (visual acuity) - endothelial cells microscopy - OCT macula and optic nerve - Catquest 9SF; - Barthel Index; - Six Item Cognitive Test - Confusion Assessment Method (CAM): this exam will be performed within 24 hours of post-surgery and 20 days after surgery. It is important to underline that the cognitive tests proposed to patients consist of simple questions that do not depend on the visual ability of the subject.
Determine safety of plasma infusion or exchange in APOE 44 patients.
6-month, randomized, controlled investigation measuring the effect of increased clinical contact and personalization compared to standard physician counseling on adherence to consensus-based, brain health recommendations for patients with subjective cognitive decline, mild cognitive impairment, and early dementia or patients who are at risk for developing these conditions.
Mild cognitive impairment (MCI) is a syndrome defined as an intermediate stage between cognitively intact and clinically diagnosed dementia. The progression rate from MCI to dementia ranges from 10 to 15% each year, resulting in increased family care and medical expenses. Therefore, providing effective interventions are necessary. Combining cognitive training and physical exercise training appears to have effects to prevent the progression of MCI to Alzheimer's disease or other severe cognitive impairment. It was proposed that cognitively challenging stimulations can increase the neural network and promote neural plasticity, which are essential for preventing cognitive decline in patients with MCI. The studies also showed that physical exercise induces positive effects on cerebral blood flow and induces brain activation changes of the frontal, parietal, and temporal areas; these cortical areas are especially important for memory and other cognitive functions. However, it is yet not clear the appropriate frequency of the effective intervention for patients with MCI. Thus, this study aims to compare the intervention effects of high frequency sequential and low frequency sequential training for patients with MCI.
This is a single center imaging study that will recruit 60 participants who are enrolled in the Effect of a Ketogenic Diet on Alzheimer's Disease Biomarkers and Symptoms: Brain Energy for Amyloid Transformation in AD (BEAT-AD) Study protocol. This cohort of patients will receive a maximum of 3 [11C]Acetoacetate (AcAc)/[18F]Fluorodeoxyglucose (FDG) PET scans over 18 weeks as part of this supplemental trial.
Participants enrolled at the Alzheimer's Disease Research Center (ADRC) at Wake Forest School of Medicine will be invited to take part in this study. The purpose of this study is to identify and measure the amount of a protein called amyloid in the brain.It is thought that the build up of amyloid may be related to the development of Alzheimer's disease.
