Filter by:The investigators will compare two brain health programs in older adults with subjective cognitive decline and lifestyle risk factors for dementia. The primary aim of the study is to determine the credibility, expectancy, feasibility, acceptability, appropriateness, fidelity, and satisfaction of the programs.
The Inserm NeuroPresage team has been using MRI for more than 20 years in the study of normal ageing and memory pathologies to further the understanding and the characterization of early diagnosis and the cerebral substrates of cognitive deficits in patients, particularly in the context of neurodegenerative diseases. Two years ago, a new 3T MRI camera was installed at the Cyceron centre. It is more efficient and should make it possible to obtain better quality images and/or to reduce the time required to acquire these images. In this context, it seems important to test the different sequences that we classically use in our studies, or that we plan to implement in our next studies (learning and text retrieval fMRI task), in order to optimize them, with a view to integrating them in our future studies.
The goal of this clinical trial is to test 6 months of aerobic exercise in older adults who are 65 years or older and have mild cognitive impairment (MCI) or probable/possible mild Alzheimer's Disease. The main questions it aims to answer are: - test the effects of aerobic exercise on aerobic fitness, white matter hyperintensity (WMH) volume, and patient-centered outcomes; - identify the best exercise to improve aerobic fitness and reduce non-responses over 6 months; and - examines the mechanisms of aerobic exercise's action on memory in older adults with early AD. Participants will receive 6 months of supervised exercise, undergo cognitive data collection and exercise testing 5 times over a year span, have an MRI brain scan 3 times over a one-year span, and have monthly follow-up discussions on health and wellness.
The goal of this clinical trial is to evaluate a program for adults who live alone and have some cognitive impairment (CI) to see if it is useful and acceptable. This program aims to help older adults with cognitive impairment who live alone to be engaged and active, as well as safe at home. The investigators want to see how useful this program is and how it can be improved. The specific aims are: - Specific Aim 1: Develop and Adapt Home Alone to Prepare for Pilot Testing. - Specific Aim 2: Pilot Test a Revised Version of Home Alone. Phase I participants will be asked to: - Participate for 3 months - Complete 3 surveys - Complete 7 1-hour meetings on a weekly basis with a coach - Complete a final interview Phase II participants will be asked to: - Participate for 6 months - Complete 3 surveys - Complete 7 1-hour meetings on a weekly basis with a coach - A sub-sample will be asked to complete a final interview
The overall objective of this project is to characterize the spatiotemporal dynamics of brain oscillations underpinning autobiographical memory (ABM) and the modulation of the memory network using non-invasive brain stimulation.
This study will compare smartphone usage data between three groups of patients diagnosed with either a memory complaint, mild cognitive decline, or Alzheimer's disease.
In this study the participants can be recruited via scheduled consultation and external institutions (associations, senior club..). Neuropsychological assessment will be realize to determine presence or absence of neurodegenerative disease. Study test is ecological MAI. This test are assigned in two groups (with or without neurocognitive disorders).
Working memory (WM) deficits are a transdiagnostic feature of adolescent psychopathology that substantially contribute to poor clinical and functional outcomes. This proposal will utilize a multimodal neuroscientific approach to investigate whether non-invasive brain stimulation can modulate the neural mechanisms underlying adolescent WM deficits. Directly in line with NIMH priorities, the researchers will identify the contributing roles of prefrontal and parietal regions in WM processes, as well as identify optimal targets and parameters for novel brain-based treatments in adolescent psychopathology. This study is funded by the NIMH-K23
This project aims to examine the efficacy of remote, caregiver-led tES/brain stimulation intervention targeted to improve memory, mobility, and executive functioning among older adults with mild cognitive impairment or mild dementia.
The goal of this study is to learn about the effects of scopolamine (an anticholinergic drug) on areas of the brain involved in memory, and changes it may have on brain activity. The investigators will do this by testing epileptic patients who are already undergoing intracranial surgery for seizure monitoring, and measuring the activity from the brain areas being assessed. The main questions it aims to answer are 1) whether scopolamine changes memory activity solely at encoding (the time when the person perceives and determines to remember an item or event) as has previously been found, or if it also can selectively impact retrieval (when the item or event which has been processed is recalled or remembered), and 2) what the nature of the brain activity changes is. Participants will complete two treatment arms. One of these will be with the drug, and the other will be with a saline solution, so that the participants are unaware which session the actual drug has been received. Patients will complete a verbal and/or spatial task each of the two days. An anesthesiologist will administer either the drug or the saline at a critical point which addresses both of the research questions. Researchers will compare the brain activity between the two treatment arms to determine what brain activity changes, and at what time point during memory formation.
