Filter by:The primary goal of this project is to evaluate feasibility and acceptability of the MIND+SOUL diet and its implementation. Secondary goals of this project are to evaluate cardiovascular risk profile, nutritional health status, and cognition in relation to the MIND+SOUL diet intervention.
The present study aims to establish a non-pharmacological alternative in alleviating cognitive deterioration derived from undergoing chemotherapy treatment. Thus, the effectiveness of a personalized and computerized cognitive stimulation program in breast cancer survivors is assessed.
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.
Study Design & Recruitment: Phase III randomized controlled trial (RCT) with 200 patients. Participants with a diagnosis of late-life depression (LLD), excluding dementia and other psychiatric comorbidities, will be recruited at three health networks. LLD patients had no earlier depressive episodes before the age of 65. Interventions: Mindfulness-based Cognitive Therapy (MBCT) or Health Enhancement Program (HEP) for 8-weeks, in addition to TAU. MBCT and HEP will have the same group sizes, meeting frequency, and amount of home practice. HEP is a recognized active control where participants learn about diet and exercise, but not meditation.
The purpose of the Health and Energy through Active Living Every Day (HEALED) intervention, is to examine the effect of a web-based intervention on changes in device-measured physical activity (light and moderate-to-vigorous intensity aerobic) and sedentary behavior. The purpose of this study is intended for survivors of a cancer with a 5-year survival (at Stage I, II, and III) of at least 45% that has a strong level of evidence for association with physical inactivity according to the 2018 PA Guidelines Advisory Committee Report (breast, colon, endometrium, kidney, bladder, multiple myeloma). In line with social cognitive theory behavior change techniques, participants will be provided information and skills necessary to be more physically active and less sedentary after a cancer diagnosis. New materials will be disseminated biweekly through a website open only to participants, and include at-home exercise demonstration videos, research news, discussion boards, success stories, infographics for exercise recommendations, etc.
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.
Time restricted eating (TRE) is currently the most popular form of intermittent fasting which involves confining the eating window to 8-10 hours (h) and fasting for the remaining hours of the day. TRE is unique in that during the eating window, individuals are not required to count calories or monitor food intake in any way, resulting in high adherence. Accumulating evidence suggests that TRE produces a natural energy deficit of ~350-500 kcal/d. Physical activity in combination with a healthy diet pattern is recommended for older adults. While aerobic type exercise is the most commonly recommended, retention of lean mass via resistance training, especially in older adults, may be more effective at improving mobility, neurological and psychological function, executive and cognitive functioning, and processing speed. TRE combined with physical activity has not been examined in older adults or in people with overweight or obesity. This study holds the potential to 1) decrease body weight 2) improve lean mass 3) improve insulin sensitivity, and 4) improve attention, executive functioning, and processing speed in older adults. The aims of this study will examine the effect of TRE combined with either resistance training or aerobic training on body weight, body composition, metabolic disease risk, and cognition in adults over age 50. It is hypothesized that the TRE combined with resistance training group will see the most significant improvements in body composition, insulin sensitivity and cognition due to lean mass accretion.
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.
