Filter by:The NeuroFit study will be investigating the impact of exercise on global cognition, hippocampus-dependent memory function and the gut microbiota in a middle-aged population.
We will conduct a Tau PET scan in cognitively normal older adults, enrolled in the Aging Brain Cohort Dedicated to Diversity Study (ABCD2-Tau) study at the University of Pennsylvania's Penn Memory Center/Alzheimer's Disease Core Center (PMC/ADC).Study duration will generally be a one-day study visit for PET imaging, but all subjects will be followed annually as part of their participation in the ABCD2 study. Findings from this study will likely provide insight into the mechanisms and distinctions of age-related cognitive decline and that of preclinical Alzheimer's Disease.
Anterior temporal epilepsy is the most frequent form of focal epilepsy (more than 50% of focal epilepsies). The epilepsy is drug-resistant when epileptic seizures persist despite antiepileptic treatment (25% of cases). In this case, it is possible to offer a surgical solution to the patient: an anterior temporal lobectomy. This surgery consists of removing the entire portion of the temporal lobe responsible for epilepsy (epileptogenic zone), that is to say a major part of the temporal pole, the hippocampus and the ventral anterior temporal lobe (vATL). The goal of the surgery is to lead to a disappearance of the seizures while preserving the functions of the patient. This is why a pre-surgical assessment is systematically carried out in order to locate the epileptic focus and to predict the risks of neurological and cognitive deficits. The vATL is of particular interest because it is a highly functional region, involved in naming, semantic processing and face recognition. A resection of this region by anterior lobectomy can therefore impact these functions and lead to cognitive deficits (for example, up to 65% decline in naming), which can be disabling in the lives of patients, even if they are free from seizures. One of the major challenges of epilepsy surgery is therefore to predict the postoperative neuropsychological outcome. The prediction of the neuropsychological outcome of the post-surgery patient is largely based on the mapping of functional regions preoperatively, carried out by functional MRI (fMRI), or by electrical stimulation carried out during intracerebral exploration by StereoElectroEncephalography (SEEG). However, current techniques have drawbacks. Electrical stimulations are based on an invasive exploration (SEEG), are time-consuming and sometimes difficult to interpret. The fMRI sequences used in clinical routine do not make it possible to visualize the entire vATL region because of artifacts related to the auditory canal. Thus, the signal is strongly diminished in this region, rendering a large area of the vATL invisible. This results in insufficient visualization of activated vATL regions when performing tasks such as naming, semantic processing, and face recognition. Important functional regions can therefore be removed during surgery and negatively impact the patient's neuropsychological outcome. In the CARTA study, original methods are associated in order to increase the signal-to-noise ratio in vATL. On the one hand, the Multi-Band sequence, an innovative fMRI sequence, will be used. On the other hand, a particular method of presentation of visual stimuli will be used, called fast periodic visual stimulation (FPVS: Fast Periodic Visual Stimulation), during which the stimuli are presented periodically (fixed frequency). Individually, these methods improve vATL (signal enhancement) exploration. The investigators assume that the combination of the two methods may have a potentiating effect, compared to the standard SMS (Simultaneous Multi-Slice) sequence. fMRI exploration will not influence the surgical management of the patient included in the study because it is the beginning of the development of this technique, but could be used, in the longer term, to guide the surgeries of epileptic patients. Thus, the goal of this study is to precisely map the vATL, using innovative methods in fMRI. This mapping will make it possible to study the cerebral functions of the vATL involved in naming, semantic processing and face recognition, and ultimately improve the postoperative neuropsychological prognosis of epileptic patients.
The Cardiovascular Disease Cohort study is a prospective cohort study among cardiovascular disease patients enrolled in the Affiliated Hospital of Hangzhou Normal University. The primary aim of this study is to explore the brain mechanism of cognitive decline in cardiovascular disease patients using RS-FMRI and multi-omics techniques (including microbiome and metabolomics). Another aim of this study is to develop diagnosis and treatment strategies combining cardiovascular disease and cognitive function.
Investigators propose to study youth across the spectrum of body mass index (BMI) and dysglycemia. This approach will allow investigators to disentangle the relationship of key features of type 2 diabetes (T2D) risk (e.g. obesity) with intermediary physiologic changes (e.g. insulin resistance, inflammation, β-cell dysfunction and dysglycemia) that pose a risk for the brain. Investigators will determine which of these factors are most associated with differences in brain structure and function among groups, over time, and how these effects differ from normal neurodevelopment.
PROMED-EX is a single-blind, parallel group randomised controlled trial to determine the effect of a PROtein enriched MEDiterranean diet (PROMED) in comparison to a PROtein enriched MEDiterranean diet and EXercise (PROMED-EX) intervention, or standard care on the nutritional status and cognitive performance of older undernourished adults with subjective cognitive decline.
Neurocognitive decline is a health issue that is associated with ageing. It is often irreversible from the onset. The concomitant costs of neurocognitive decline could be potentially exponential if left unchecked. Therefore, there is a need to be able to delay the onset of age-related neurocognitive decline or possibly avoid it altogether. Previous studies have shown that there is a strong positive relationship between the fitness of neurocognitive function and cognitive training. More interestingly, recent studies also suggest that combining cognitive training with physical activity may result in a better outcome for neurocognitive function as compared to only cognitive training. Anchoring on the findings of those studies, the investigators aim to develop and evaluate the efficacy of a novel personalized multimodal brain computer interface (BCI) cognitive and physical training system for neurocognitive protection and enhancement in older adults. The current study employs a three-arm randomized-controlled trial approach. The investigators hypothesize that participants in the multimodal cognitive and physical training (mBCI) group will perform significantly better than the cognitive training-only BCI (nBCI) and active control (AC) groups on the Repeated Battery for the Assessment of Neuropsychological Status (RBANS) after an initial high-intensity 36 training session period from pre- to 12 weeks post-intervention. The investigators also hypothesize that the mBCI group will perform significantly better on the RBANS than nBCI or AC groups after the consecutive high- and low-intensity periods from pre- to 24-weeks post-intervention.
This study is a phase III Randomized Clinical Trial, prospective, placebo controlled of 12,268 subjects with low to moderate risk of stroke followed by 3 years in 60 Primary Health Care Units in Brazil. The units will be randomized (clusters) to use or not the approach of community health workers with the Stroke Riskometer. After, patients will be randomized to receive the polypill (valsartan 80 mg, amlodipine 5 mg and rosuvastatin 10 mg) or placebo (dose adjustment of amlodipine 2,5 for patients with adverse events). The purpose is to test whether a polypill alone or in combination with lifestyle modification will reduce the incidence of stroke and cognitive impairment in this population.
Residents living in long-term care (LTC) homes spend up to 75% of their day in sedentary, socially withdrawn situations which increases their risk for depression, dementia, decreased functional status and increased care costs. Physical activity is an accepted intervention to improve the physical health, cognition, and well-being of older adults. Moreover, systematic reviews have found that exergaming (i.e. physical activity gamified with technology) offers physical, cognitive, and social benefits by means of dual-task activities that engage both motor and cognitive abilities. The effect of exergaming for older adults in LTC is less clear, as this population has greater health needs related to physical health conditions, cognitive impairment, and functional dependence. Given the increased global demand for LTC, there is a need to develop and assess innovative exergaming technologies that can support the physical and cognitive health of LTC residents. MouvMat is an exergaming technology intervention with an interactive digital gaming surface designed for older adults (OA) in LTC settings. Participants can play familiar games, like Simon or Bingo, by stepping on or tapping the surface with an assistive pointing device. Games can be played individually or with multiple players. LED lights on the surface provide an adaptive digital display and embedded pressure sensors respond to players' input. The investigators collaboratively designed a preliminary prototype with OA aged 65 and older in a pilot project. The overall objective of this proposal is to conduct a pilot RCT of the Mouvmat to evaluate the feasibility, acceptability and efficacy of the exergaming technology to improve the primary outcome of mobility, and the secondary outcomes of cognitive function and social isolation compared to a usual care control group receiving standard recreational programming by recreational therapists.
Cognitive complications, that is problems with thinking and memory, are incredibly common after surgery, occurring in 10-50% of all older surgical patients. These complications can take different forms, but one of the most common is postoperative delirium (POD), a short-term state of confusion. In addition to being stressful for patients and their families, POD is linked to longer hospital stays, increased costs, higher mortality rates and other problems after surgery. Despite this, POD is often not recognized by doctors and there are currently no effective medications to treat POD. However, simple strategies such as helping patients to sleep properly and remain hydrated, have been shown to help. This study is testing if a delirium-reduction program will reduce postoperative delirium (POD) in older surgical patients. The investigators will first test memory and thought processes before surgery to find people who are most likely to develop POD. Once these people have been identified, they will be enrolled in a program which includes recommendations for their care team (e.g. surgeon, anesthesiologist, nurses) as well as educational materials for them and their family related to things that can be done to prevent delirium. By identifying at-risk patients and making sure that their doctors and caregivers are aware of how to prevent delirium, the investigators expect that this study will make surgery safer for older surgical patients.
