Filter by:The present study will investigate the correlation between objective and subjective cognition in multiple sclerosis. The study will also investigate the impact of covariates such as fatigue and depression, the relationship with the Expanded Disability Status Scale (EDSS) and brain volumetrics as measured on magnetic resonance imaging (MRI). Additionally, the study will provide insights into patients' experiences with cognition, and the usability of the used objective cognitive assessments.
Sleep apnea is characterized by temporary pauses or stops to participant's breathing. Currently, sleep apnea is diagnosed using an in-lab sleep study, which involves spending a night in a sleep laboratory hooked up to wires on the head, chest, and legs. However, this is not feasible for many older adults. To overcome this barrier, the investigators will utilize an investigational vital signs monitor - the Advanced NeoNatal Epidermal (ANNE) Vital Sign System (Sibel Health, Evanston, IL,USA). The primary objective of this study is to test the hypothesis that sleep apnea is associated with accelerated cognitive decline in older adults at risk for dementia. The investigators will measure sleep apnea at baseline and 12 months later and relate this to cognitive function at the same time points. Sex-stratification will be used in analyses as appropriate. Qualitative feedback forms will be used to collect information about participant ease of use and experience with the ANNE Vital Sign System.
To investigate the impact of rTMS on the incidence of perioperative neurocognitive disorders in patients after after cardiac surgerysurgery. To explore the underlying mechanisms behind the efficacy.
The main empirical question to be addressed is: What types of memory support are most potent for patients who are experiencing a mild cognitive impairment (MCI) relative to non-MCI patients?
This study is a prospective observational study, which involves a cohort of 2000 all-sex and all-ethnic people aged 60 years and above with permanent residence in Tianma area, SheMountain Town, Songjiang District (suburban area), Shanghai. Demographic information, neuropsychiatric scale, peripheral blood, APOE genotype, brain MRI, speech information, AV45-PET, FDG-PET, Tau-PET, GLP-1R PET, and cholinergic receptor probe (ASEM) PET were collected and analyzed. Follow-up visits were performed twice a year for 4 visits, and neuropsychiatric scales and biological samples were collected at each follow-up visit to construct a diagnostic model for patients with mild cognitive impairment, or Alzheimer's disease, as well as a predictive model for the progression of cognitive impairment.
Since 2010, the field of immunotherapy has grown substantially, leading to a growing population of long-term cancer survivors treated with immunotherapy. Since cancer survivorship in immunotherapy is an emerging field, to date not much is known about psychosocial and neurocognitive survivorship-related issues in advanced cancer survivors treated with immunotherapy. Preliminary findings indicated significant psychosocial and cognitive problems in survivors of advanced melanoma persist after treatment with immunotherapy. The objective for this project is twofold. First, the investigators want to longitudinally identify survival-related problems in survivors of advanced cancer treated with immunotherapy. The second goal is to identify the efficacy of an Integrative Neuro-Cognitive Remediation Therapy (INCRT) program. The investigators will focus on the following outcomes: (1) Psychosocial consequences, such as emotional complaints, fatigue, fear of recurrence, (2) neurocognitive functioning, and (3) health-related quality of life. The INCRT combines personalized computerized cognitive training and neurocognitive strategy training, with group sessions of exercise, mindfulness, Acceptance and Commitment Therapy, and cognitive behavioral therapy. We will have three cohorts: - Cohort 1: advanced cancer survivors treated with immunotherapy - Cohort 2: cancer survivors treated with cancer therapy of any kind (excluded immunotherapy), and who have subjective complaints and/or objective cognitive impairment - Cohort 3: cancer survivors of a central nervous system (CNS) tumor, who do not have active disease in the CNS, and who have subjective complaints and/or objective cognitive impairment In the first part of the study, survival-related problems will be evaluated in cohort 1, in a longitudinal manner by means of a semi-structured interview at baseline, various questionnaires and a computerized neuropsychological test battery. In the second part of the study, patients of cohort 1, 2 and 3 with subjective or objective cognitive dysfunction can follow the INCRT program. The efficacy of the INCRT is evaluated through a pre-INCRT and post-INCRT evaluation. This evaluation consist of several questionnaires and neuropsychological tests. Long-term efficacy will be evaluated by a follow-up evaluation six months after completion of the INCRT program.
Different cognitive rehabilitation intervention methods have been developed for the treatment of cognitive dysfunctions seen in mild cognitive impairment (MCI). The aim of this study was to examine the effectiveness of cognitive rehabilitation intervention applied with the telerehabilitation method in elderly patients with amnestic-MCI. Participants included in the study according to inclusion and exclusion criteria were randomly assigned to the telerehabilitation and face-to-face groups. A 12-week cognitive rehabilitation intervention was applied to both groups. Pre- and post-intervention cognitive skills of the participants were evaluated using the Loewenstein Occupational Therapy Cognitive Assessment-Geriatric (LOTCA-G).
The research is focused on ameliorating cognitive decline in aging and in individuals diagnosed with Mild Cognitive Impairment (MCI). In the proposed research, we ask whether synaptic plasticity is modified by exercise in these groups and if these changes relate to improved cognition. We know that cognition improves with exercise, but if we discover that synaptic plasticity is indeed modified by exercise, this opens many possibilities for us to explore new approaches to change synaptic plasticity in these populations. We view this project as benefiting all aging individuals, with or without MCI, since we are working to improve cognition. Understanding the mechanisms will help design better therapeutic strategies for older adults.
Insomnia is a common sleep disorder. In recent years, the incidence of insomnia is increasing worldwide. Studies point out that insomnia plays an important role in the pathogenesis of cognitive impairment. Although sleep and cognitive scales are the main methods to detect sleep quality and cognitive changes, there are problems such as strong subjectivity and poor repetition. There is an urgent need to use non-invasive and objective detection methods to assess the potential mechanisms of cognitive impairment caused by sleep disorders. Previous studies have shown that different brain states may show different neurovascular coupling (NVC) characteristics. However, after prolonged sleep deprivation, the evoked hemodynamics response was attenuated despite an increased electroencephalogram (EEG) signal response, suggesting that sustained neural activity may reduce vascular compliance. It is suggested that sleep disorder may lead to NVC disorder. However, whether sleep disorders regulate the mechanism of cognitive impairment in the brain through NVC disorders has not been demonstrated in vivo. Currently, functional magnetic resonance imaging (fMRI) can be used to study brain function and blood flow changes non-invasively. In our previous research, we combined cerebral blood flow (CBF) with mean amplitude of low-frequency fluctuation (mALFF), mean regional homogeneity (mReHo) and degree-centrality (DC), the early warning effect of fMRI features based on neurovascular uncoupling on early cognitive impairment was confirmed, providing a basis for further selection of functional imaging indicators. In conclusion, the present study proposes the scientific hypothesis that neurovascular decoupling-based MRI features are more appropriate for exploring the neural mechanisms underlying sleep disorders-induced brain cognitive impairment. The aim of this study is to establish an early warning and monitoring system for early non-invasive diagnosis and intervention of sleep-related cognitive impairment.
The goal of this clinical trial is to investigate the possibility of rehabilitation of mild cognitive deficits in people with metabolic syndrome. We aim to implement a cognitive training program on patients with metabolic syndrome and cognitive deficits, and examine its effectiveness both post-intervention (3 months) and after 12 months. Researchers will compare two groups, the experimental group that will receive the computerized cognitive training and the control group that will receive no training.
