Filter by:The investigators plan to investigate the effect of enhancement on working memory (WM) in patients of chronic schizophrenia and determine the predictive factors of effective treatment.
The investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of Skate Skin extract on cognitive function in adults with subjective memory impairment for 12 weeks.
This study was designed to characterize the changes in the brain and body associated with whole coffee cherry extract (WCCE). WCCE is a patented extract of whole coffee fruit (coffee berries) from coffea arabica. Whole coffee cherries are a source of naturally occurring nutrients. There are no known side effects or allergens associated with WCCE other than that which would be associated with a consuming typical cup of coffee. Previous studies suggest that increases in serum concentrations of both serum total and exosomal brain-derived neurotrophic factors (BDNF) may represent one of the mechanisms responsible for improved cognitive function after acute WCCE administration. Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and the more serious decline of dementia. It can involve problems with memory, language, thinking and judgment that are greater than normal age-related changes. Furthermore, MCI is associated with reduced circulating BDNF. Due to earlier studies reporting the ability of WCCE to stimulate increases in circulating and exosomal BDNF, it has been postulated that WCCE may also acutely improve cognitive function (as measured using behavioral tasks and fMRI). The purpose of this study is to extend and elucidate the findings of previous investigations by examining the acute neurophysiological effects of WCCE using blood-oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) and magnetic resonance spectroscopy (MRS) employing a double-blind, randomized crossover design to investigate the acute effects of a single dose of WCCE or placebo (silica oxide) on neuronal activity in older participants.
Perceptual-cognitive training (PCT) is a computerized software game has been shown to improve sport performance in young elite athletes and even to aid in recovery speeds post-concussion. PCT may represent a unique type of training that could ultimately enhance cognitive performance or quality of life in all populations. What is not clear is whether PCT is beneficial to older adults with subjective memory complaints (SMCs). SMCs in older adults are an early risk indicator for Alzheimer's disease, making older adults with SMCs a target population for proactive interventions. The aim of this study was to determine if PCT can serve as a proactive intervention and enhance cognitive abilities in older adults with SMCs. The results of this research protocol introduce a new way of prevention from cognitive decline in healthy older adults and may introduce a new training programs for age-related memory disorder.
The proposed study will evaluate the safety, durability and efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a promising non-invasive therapeutic treatment for improving memory in older adults with mild or moderate Traumatic Brain Injury (TBI) who have been experiencing residual memory or cognitive problems that affect daily functioning.
The goal of this clinical trial is to investigate the impact of low intensity focused ultrasound pulsation (LIFUP) to two different brain regions, the amygdala and entorhinal cortex, in older adults. The main questions it aims to answer are: 1. Will LIFUP change brain activity in the targeted regions? 2. Will LIFUP to the amygdala have an impact on anxiety and emotion regulation? 3. Will LIFUP to the entorhinal cortex have an impact on memory performance? Participants will complete two in-person visits including neuropsychological testing, MRI of the brain, and LIFUP to the brain.
The goal of this study is to determine the acceptability, utility, and preliminary effectiveness of a facial recognition technology for persons with memory concerns and their family care partners.
The ability to find one's way in the world is known as wayfinding. Many older adults who live in senior communities, such as independent living and assisted living residences, find wayfinding very challenging. Often times, these communities are not designed in a way that helps people find their way very easily. When people cannot find their way, they can get lost, be dependent upon others for getting out and about, or even be afraid to leave their rooms. The purpose of this study is to find out if distinctive signs and decorative elements, along with a special type of education called Spaced-Retrieval education, help residents in these communities find their way more effectively. Twelve senior communities will be assigned by chance to one of three conditions, including: 1) control - no change (the community stays the same); 2) signs and decorative elements enhanced; and 3) signs, decorative elements, and special education added. After agreeing to be in the study, the participants will be asked to find their way to certain places in their community four times over a year. Some people will be asked to participate in educational sessions on wayfinding. In addition, some people will be asked to wear a location tracker, (like a fitness tracker), for four weeks during the year. How well people find their way, along with how much they travel about within the communities, will be compared between the three groups. It is hypothesized that those in the communities with special signs and decorative elements will find their way more effectively than those in the control communities. It is also hypothesized that participants in the communities with the special education intervention will find their way better than those without the education. Finally, it is hypothesized that participants in the communities with signs and cues and education will travel about further distances than those in the control communities. The results of the study can help people who have a tendency to get lost find their way more effectively in their community, and this could result in more independence.
The study has both quantitative and qualitative components. The objective of the quantitative study is: 1. To culturally adapt and refine Montessori activities for people living with dementia in Pakistan. 2. To determine the feasibility and acceptability of culturally-adapted group based Montessori intervention for people with dementia in Pakistan. 3. To build capacity and capability in dementia research (researcher training) The objective of the qualitative study is: To explore views on perceived effectiveness and sustainability of the study.
The aim of this study is to investigate the effect of a transcranial electrical stimulation (tES) on a cognitive training in healthy elderly and memory impaired participants. In order to assess these effects different memory and attention tasks will be performed before and after the training as well as after 6 and 12 months.
