Filter by:The purpose of this study is to assess the effects of non-invasive brain stimulation on memory and language ability in patients with two phenotypic variations of underlying Alzheimer disease pathology: amnestic mild cognitive impairment (aMCI) and logopenic variant of primary progressive aphasia (lvPPA). This study will use repetitive Transcranial Magnetic Stimulation (rTMS) to stimulate nodes of networks that are thought to be affected in these two conditions. Specifically, a node of the Default Mode Network (DMN)-the angular gyrus (AG)-will be stimulated in aMCI patients; and a node of the language network-the posterior inferior frontal gyrus (pIFG) will be stimulated in patients with lvPPA. We will use functional connectivity MRI (fcMRI) to assess changes in functional network architecture following the stimulation. We will also assess putative cognitive improvements resulting from the stimulation by in-depth language testing in lvPPA patients and in-depth memory testing in aMCI patients.
We aim to conduct a pilot randomized controlled trial comparing 2 symptom management programs for older adults with self-reported memory problems and chronic pain, Active Brains 1 and Active Brains 2. We will assess how each program may help in improving coping with pain and coping with cognitive functioning. We will explore feasibility, acceptability, and credibility and within group changes in physical, emotional and cognitive functioning.
Individuals with mild cognitive impairment (MCI) and subjective cognitive decline (SCD) have greater risk of developing dementia. Cognitive intervention is a topic of great interest in individuals with MCI and SCD for the purpose of preventing or delaying the occurrence of dementia. There are many different types of cognitive interventions, which aim to positively impact the cognitive functioning of an individual and have been classified as cognitive stimulation, cognitive training, and cognitive rehabilitation. However, most studies used neuropsychological cognitive measures for outcome evaluation. The impact of cognitive interventions on daily functional performance among individuals with MCI and SCD were rarely explored. In addition, cognitive training focusing on specific cognitive outcomes is suspected to have limited far transfer to everyday measures. Therefore, a multicomponent intervention which integrates several types of intervention is recommended to reach the maximum impact on daily function. The purposes of this study are to examine the effects of a multicomponent cognitive intervention on cognitive and daily functional outcomes in individuals with MCI and SCD, and to compare the effects between the two groups. In addition, the investigators will also investigate whether the demographic (e.g., age and educational level, etc.) and clinical variables (e.g., duration of cognitive complains, level of depression and baseline cognitive function, etc.) may affect the outcomes of cognitive intervention.
Increased activity in the hippocampus (i.e., hyperactivity) during a fMRI memory task was found in patients with Mild Cognitive Impairment due to Alzheimer's disease (MCI). Those with increased hippocampal activity exhibited elevated clinical progression. Reducing hippocampal hyperactivity with pharmacological treatment reduced hyperactivity and improved memory performance. The investigators of this study will test whether real-time fMRI neurofeedback will also downregulate hippocampal activity and thereby improve memory performance.
Pretest and validation of the German version of the Amsterdam instrumental activities of daily living questionaire short in elderly people with normal cognition, mild cognitive impairment (MCI) or mild dementia in the German speaking part of Switzerland. The aim is to investigate the psychometric properties of the final Amsterdam instrumental activities of daily living questionaire short (A-IADL-Q-SV) German. Participants with normal cognition will be recruited in the community and participants with MCI and mild dementia in three memory clinic settings.
This study evaluates the effects of Mindfulness-based Interventions (MBI) on the neuropsychological profile of individuals with mild cognitive impairment (MCI). It will also investigate changes in fMRI activity, such as resting-state functional connectivity networks and changes in activity in attention networks in task-related fMRI using graph theory analysis after Mindfulness-based Interventions. Participants will be randomly assigned to receive either the Mindfulness-Based Intervention, Cognitive Rehabilitation Training or Treatment as Usual as the passive control group comparison.
Alzheimer's disease (AD) is the most common form of neurodegenerative disorders leading to dementia. Currently, there has been no effective drugs targeting this disease. Dysbiosis of the gut microbiota is considered to be associated with AD, and probiotic supplementation may positively affect cognitive function. However, there are few studies involving the relationship between intestinal microorganism and amnestic mild cognitive impairment (aMCI). In this project, taking the method of random, double blindness and control, the probiotic supplemented group with aMCI will take certain Bifidobacterium for a certain time. After that, the investigators aim to investigate the improvement of cognitive function and changes of intestinal microbial flora diversity via combining neuropsychological tests and 16S recombinant deoxyribonucleic acid (rDNA) high-throughput sequencing technique. Furthermore, based on the multi-modal neuroimaging techniques, the regulatory mechanism of intestinal microorganism in intervening aMCI will be revealed from the perspective of brain networks. In conclusion, these results are beneficial for understanding the therapeutic effect of gut microbiota as a non-drug treatment for early AD and further elucidating the potential brain mechanism, which are of great values in solving scientific and clinical practice issues.
The process of receiving a diagnosis of mild cognitive impairment (MCI) is recognized to induce behavioral responses that can be either adaptive or maladaptive. Five specific areas of concern have been identified, including: 1) failure to plan for future decline, decreased compliance and interaction with medical care providers, 3) decreased confidence and reduced social engagement, 4) increased physical limitations and 5) decreased medication compliance. In this pilot study, participants with MCI and their study partners will participate in behavioral interventions (primarily training workshops and classes) targeting each of these five areas of potential maladaptive behaviors.
This study evaluates acceptability and efficacy of multidomain intervention program to prevent cognitive impairment and protect brain health in Korean at-risk elderly. A third of participants will receive facility-based intervention for 6 months, a third will receive home-based intervention for 6 months, and a third is waiting list controls.
Progressively causes the breakdown of cognitive functions and impairs quality of life for patients and their caregivers. In addition to memory impairment, visual attention is also compromised, even at the stage of mild cognitive impairment due to AD (MCI-AD). No treatment has been found for MCI-AD; therefore, attention has been drawn to non-invasive brain stimulation techniques, such as transcranial direct current stimulation (tDCS), in order to enhance cognitive functions by modifying brain plasticity. In the current research, investigator aim to examine the long-term effects of the optimal multiple-session tDCS protocol in MCI-AD on visual attention including the transfer to an ecologically valid virtual environment and identify the neural underpinnings of tDCS-induced behavioral aftereffects using a combined tDCS/ MRI network-based approach.
