Active clinical trials for "Memory Disorders"

This is a four-site, randomized, parallel design, double-blind, placebo-controlled, 10-week trial of donepezil 10 mg daily for verbal memory problems among adults with TBI in the subacute or chronic recovery period. The study will recruit 160 persons with TBI and functionally important memory problems during a four-year period of open recruitment. The study aims are: To evaluate the effects of treatment with donepezil on verbal memory as assessed by the Hopkins Verbal Learning Test-Revised Total Trial 1-3; To evaluate the effects of treatment with donepezil on memory-related activities as measured by the Everyday Memory Questionnaire; To evaluate the effects of donepezil on attention, processing speed, neuropsychiatric symptoms, community participation, quality of life, and caregiver experiences.

The purpose of this study is to evaluate if systematic cognitive training can improve cognitive performance in participants (55 and older) with memory loss. This study will evaluate the effects of Computerized Cognitive Training (CCT) for improvement in everyday cognitive and function status, in addition to long-term changes in brain networks over an 18-month period. Although there is no distribution of medication for this study, participants are required to have an at-home computer.

Researchers at the University of North Carolina at Greensboro conduct a single-arm intervention trial to investigate the efficacy of a music-based group exercise program for community-dwelling older adults. Up to forty participants will be recruited to participate in a music-based light-to-moderate intensity group exercise program for 20 weeks (30 - 40 min/day, up to 6 days/week), which is designed for older adults with or without functional limitations to exercise with chairs for the improvement of aerobic capacity, upper and lower body strength, and balance control at a gradually increasing pace. During the exercise sessions, participants will be trained to move in time with music playlists in synchronous tempos. Primary outcomes are cognitive performance, mobility, and health-related quality of life measured before and after the intervention. Secondary outcomes are adherence to the exercise program as a potential mediator of the treatment.

Alzheimer's disease and its preclinical stages are characterized by progressive neurodegenerative changes in the hippocampi and default mode network resulting in dysfunctions in episodic memory and its central part the associative memory. Associative memory allows for learning and remembering the relationship between unrelated items. Previous research suggests that non-invasive brain stimulation can influence associative memory but with the caveat of quite a small precision and relatively small effects due to the ability only influence superficial brain areas. Novel Brain stimulation techniques such as temporal interference stimulation (TIS) allow overcoming these caveats by allowing focal non-invasive deep brain stimulation. The main goal of this pilot clinical trial is to modulate associative memory among healthy seniors by influencing the cortico-hippocampal circuits using TIS. Secondly, the goal is to use functional magnetic resonance imaging (fMRI) and EEG to explore the neural correlates of TIS effects on brain networks and find biomarkers that allow predicting better response to brain stimulation.

Supplements and functional foods are now readily available and usable by the general population. Many supplemnets are commonly used in poly-treated patients where interactions or adverse events may develop, therefore we evaluate in the rela life the use of nutraceuticals, their clinical effects and the development of adverse drug reactions

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 is a pilot study of non-invasive transcranial magnetic stimulation (TMS) to improve memory in healthy adults. It will also examine treating memory deficits in older adults with amnestic mild cognitive impairment (aMCI), a condition that frequently precedes Alzheimer's disease (AD. The study will test whether a form of non-invasive brain stimulation repetitive transcranial magnetic stimulation (rTMS) can improve memory abilities in healthy young adults, healthy older adults, and older adults with aMCI by retuning memory-related brain networks. This study is a key first step which will support the long-term goal of treating memory deficits in neurological patients. It is expected that rTMS will improve memory abilities in all participants, and that the improvements in memory will be attributable to changes in the connectivity of memory-related brain networks.

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).

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.
