Filter by: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.
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.
Advancing age is associated with an increased risk of developing dementia which can lead to a rapid acceleration in both the healthcare costs and caregiver burden. There is a need to develop non-pharmacological and easily accessible modalities of support for the well-being and enhancing quality of life for individuals with dementia. There is evidence that music listening is associated with stress and anxiety reduction in older adults. Here, the investigators aim to assess the effects of music listening as provided by a novel digital music-based intervention (developed by LUCID) on mood, anxiety, and quality of life in individuals at the early stages of dementia. LUCID uses reinforcement learning machine learning to curate and personalize the musical playlist while incorporating monoaural theta auditory beat stimulation (ABS) into the music. The study will be conducted remotely with study hardware (tablets and Bluetooth speakers) being delivered to caregivers/participants. The study will take place over an 8- week period, with participants completing four 30 mins music or audiobook listening sessions per week. Pre and post-intervention assessments will be done via Zoom with the presence of a research staff member. The control condition consists of a randomized list of short audiobooks. The experimental condition consists of music and monoaural ABS curated by LUCID's AI system. The investigators hypothesize that the LUCID AI music curation system, compared to audiobooks, will be correlated with a greater reduction in measures of anxiety and agitation and an enhancement of mood and quality of life.
The aim of the present randomized-controlled study is to evaluate the feasibility, acceptability, and preliminary efficacy of a novel, context-sensitive neuropsychological rehabilitation intervention for brain cancer survivors.
This study will investigate the feasibility of implementing a time-restricted eating intervention in females with mild cognitive impairment. Targeted therapeutic interventions that improve cognitive impairment and delay onset of ADRD are particularly important for females, who have twice the lifetime risk of developing AD, compared to males.
The long-term impact and effects of COVID-19 are still being determined. However, what is clear, is that some people are still struggling following a period of illness with COVID-19. Now known as 'long covid' or 'post covid-19 syndrome', people are not only experiencing physical symptoms like fatigue and breathlessness, but also psychological difficulties, as well as cognitive changes often referred to as 'brain fog'. This can include symptoms, such as changes in memory, difficulties with organisation and problem solving, as well as the ability to concentrate. Evidence from other research areas suggest that these changes could be due to shrinkage in areas of the brain that control functions like memory and concentration. There are also connections between different brain areas that work together to perform tasks such as remembering and concentrating, and these areas may also be affected by COVID-19. The purpose of this study is to scan the brains of patients reporting cognitive changes having been hospitalised with COVID-19 infection to see if any of these areas or connections have changed after infection and whether this might explain these cognitive changes.
The purpose of this pilot study is to evaluate the feasibility of a cognitive and affective intervention for foreign born Arab American dyads consisting of the person with Mild Cognitive Impairment (MCI) and participants caregiver. This study will evaluate the feasibility of a cognitive and affective intervention combining Cognitive Behavioral Therapy (CBT), Cognitive Rehabilitation Therapy (CRT), and modifiable lifestyle factors to address the cognitive and affective dysfunctions associated with Mild Cognitive Impairment (MCI) or those with cognitive complaints. The study team hypothesizes that combining evidence-based cognitive and affective therapies (CRT+CBT) with lifestyle modifications is feasible and will improve the cognitive performance and Quality of Life (QoL) in patients with MCI and participants caregivers compared to usual care.
P-glycoprotein, an efflux transporter at the blood-brain barrier plays an important role in de development of neurodegenerative disease. A novel PET tracer ([18F]MC225) was developed to measure the function of P-glycoprotein and was tested with succes in healthy volunteers. This study aims to evaluate [18F]MC225 in neurodegenerative disease.
This is a 2-arm intervention pilot study with the objective to examine if an in-person and a remote multi-component intervention program can improve chronic stress, vascular measures, and executive function among African American and White patients with Mild Cognitive Impairment. Researchers plan to enroll 60 participants with over-recruitment of African American patients. 30 participants will be recruited from the Cognitive Empowerment Program to participate in PRogram to Improve Stress-levels and Enhance Memory (PRISEM) Cognitive Empowerment Program (CEP) (i.e., in-person lifestyle intervention program) and 30 participants will be recruited from Emory primary care clinics to participate in PRISEM Remote (i.e., remote lifestyle intervention program). The participants in both intervention arms will be asked to participate in group-based and/or individual activities that focus on improving health education, nutrition, physical activity, cognitive health, stress levels, and overall well-being. The duration of the study for all participants will be 9 months with 3 study visits. At each study visit, the following measures will be assessed: psychosocial, behavioral, vascular/physical, and executive function.
