Filter by:The goal of this study is to objectively test one's sense of smell, called olfaction, in participants with Subjective Cognitive Concerns (SCC), Mild Cognitive Impairment, Mild Behavioral Impairment (MBI), and age-matched controls. The main question it aims to answer is whether the AROMHA Brain Health Test could serve as a predictive biomarker of neurodegenerative disorders. This understanding will aid in the development of a noninvasive, cost-effective diagnostic tool that reliably and specifically distinguishes disease and normal aging populations. Participants will take the approximately 45-minute AROMHA Brain Health Smell Test where they will peel and sniff labels on the physical smell cards and answer questions on the web-based app relating to what they smelled. Participants will undergo tests for odor intensity, odor identification, odor discrimination, and episodic olfactory memory, but will not be provided the results of these tests.
The investigators conducted a validation study for the Montreal Cognitive Assessment (MoCA)-XpressO compared to the digital-MoCA test (version 8.1) as the gold standard. Participants were recruited from the MoCA clinic and a family practice. Ethics approval was received, and all participants provided informed consent. A crossover study design was applied to the MoCA-XpressO and the digital-MoCA test; participants were randomized for the order of administration. The investigators only recruited participants who did not complete a MoCA test during the 3 months prior to the study. A logistic regression model was built, and the accuracy of the model was evaluated by the sensitivity, specificity, and area under the Receiver Operating Characteristic (ROC) curve.
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.
This study is to investigate whether the improvement or maintenance of cognitive function is superior to the control group when gum chewing is performed in elderly people with subjective cognitive decline or mild cognitive impairment.
At present, many literatures have confirmed that the Mediterranean diet has the effect of delaying cognitive degeneration in patients with mild cognitive impairment, and can also slow down the speed of brain atrophy. In addition to the highly respected Mediterranean diet every year, several years of foreign research have found The maintenance of oral hygiene also has a significant relationship with the decline of cognitive function. The intervention of "oral hygiene" is a new intervention method that has started in recent years. Oral health will affect the overall health status, physical function, diet and nutritional status of the elderly. In particular, older adults with poor oral health are more likely to suffer from mild cognitive impairment. The relationship between oral health and nutrition and overall health is inseparable. If the concept of healthy eating (Mediterranean diet) recognized by the public is used and oral health education is involved at the same time. To allow patients with mild cognitive impairment to maintain oral health care in daily life, and to increase the knowledge of the Mediterranean diet and try to follow the rules of the Mediterranean diet, whether there is a more significant impact on these patients.
The purpose of this study is to evaluate the feasibility of combining repetitive transcranial magnetic stimulation (rTMS), gaze and gait training to improve walking and balance in people with or without mild cognitive impairment.
Cancer-related cognitive impairment (CRCI), also known as "chemobrain," is the cognitive decline that negatively impacts the majority of cancer patients undergoing chemotherapy, radiation, and/or hormonal treatments. This application focuses on evaluating if using a cognitive mobile training application can decrease the impact of CRCI in gynecologic oncology patients through a multidisciplinary approach with patients undergoing assessments by our neurocognitive team.
The goal of this feasibility study is to investigate the feasibility of a personalized naturalistic Virtual Reality scenario by assessing motion-sickness effects, engagement, pleasantness, and emotions felt considering a sample of individuals with cognitive impairment resident at the Azienda Pubblica di Servizi alla Persona (APSP) "Margherita Grazioli", a long-term care home in Trento (Italy) in collaboration with the Department of General Psychology - University of Padova (Italy) and the Centre for Health and Wellbeing-Fondazione Bruno Kessler (Italy). The current proof-of-concept and feasibility study is a one-session single-centre trial based on a mixed-methods approach inspired by the Obesity-Related Behavioral Intervention Trials (ORBIT) framework for the design (Phase Ib) of digital interventions and their preliminary testing (Phase IIa).
Cognitive Stimulation Therapy (CST) is an evidence-based non-pharmacological group therapy shown to benefit people with mild to moderate dementia. Despite increasing availability of CST worldwide, access remains limited in the United States. This pilot pragmatic trial will embed CST referral into the standard care protocol of health care settings that serve people living with dementia in the state of Connecticut, and evaluate online delivery of CST known as virtual CST (V-CST), and assess the acceptability of V-CST to people living with dementia. The study design is a two-armed randomized embedded pragmatic clinical trial (ePCT). The trial aims to determine if cognitive decline is experienced less commonly among V-CST participants than control group members based on three widely used measures of cognition, the Montreal Cognitive Assessment (MoCA), St. Louis University Memory Screen (SLUMS), and Mini Mental State Exam (MMSE). The study population will be persons with mild to moderate dementia identified by clinicians in standard care. From this population, subject participants will be randomized to intervention and control groups. Patients randomly assigned to the intervention group will be referred by their clinical providers to participate in V-CST, and those who accept the referral will participate in the intervention.
Recent studies suggest that gut microbiota is linked to cognitive performance and modulating gut microbiota is a safe and promising approach to enhance cognition. The limited studies in the area of probiotics for cognitive impairment in early stages warrant further research. In this feasibility study, we will examine the effects of probiotic consumption in older adults with mild cognitive impairment (MCI), on gut microbiota and cognition via microbiota composition, inflammatory, immune, and bacterial metabolite mechanisms, using neuropsychological tests. The single probiotic contains the Lacticaseibacillus paracasei strain Shirota (LcS), with proven efficacy in various health conditions as well as in stress, sleep, and mood disorders; but to our knowledge, it has not been rigorously examined in early stages of cognitive impairment. After 12 weeks of the randomized, double-blinded probiotic/placebo intervention, we hypothesize that the changes in the composition of gut microbiota, short-chain fatty acids, and the inflammatory/immunological markers, could improve functional connectivity and cognition.
