Filter by:This is an experimental study protocol to investigate the use of vision-based assessments like eye-tracking and visual processing tests to evaluate driving ability in older adults with and without dementia. The study aims to address the research gap on the specific eye movement patterns and visual behaviors of individuals with Alzheimer's disease during high-risk driving scenarios. The study will recruit 15 participants aged 65+ with cognitive impairment and 15 without cognitive impairment. Their cognitive status will be assessed using the Mini-Mental State Exam (MMSE) and Hopkins Verbal Learning Test (HVLT). Participants will undergo visual screening tests like visual sensitivity, eye movement scanning, and the Corsi block span test. Their driving performance will be evaluated through a hazard perception test and driving experience survey. Statistical analyses like correlations, group comparisons, regression, and mediation analyses will be conducted to examine the relationships between cognitive status, visual screening scores, and driving performance scores. The goal is to determine if visual measures can predict driving ability and mediate the link between cognitive function and driving performance in those with dementia. In summary, it is a protocol for an observational study using vision-based techniques to assess driving capacity in older adults, especially those with Alzheimer's disease or dementia.
Exploring the effects of repeated transcranial magnetic stimulation (rTMS) during the perioperative period on the incidence of postoperative delirium, postoperative cognitive dysfunction, and chronic postoperative pain in elderly patients, as well as its possible mechanisms.
The purpose of this study is to explore how performing two exercise-based tasks simultaneously (dual-task exercise) affects the neurovascular and cognitive responses of people with cognitive impairment, which is a growing concern globally. Specifically, the study will examine how motor-cognitive dual-task exercises, such as using elastic resistance bands combined with visual perception training, including eye movement exercises, can immediately improve outcomes such as Brain-derived neurotrophic factor (BDNF) levels, cerebral blood flow, cognitive function, and mobility. BDNF is a special chemical in our brain that helps with the connections between brain cells. Participants will be asked to complete a single 30-minute exercise session and undergo assessments before and after the intervention. Participants with cognitive impairment will be initially assessed using Mini-Mental State Examination (MMSE) which is a 30-point questionnaire used extensively in clinical and research settings to measure cognitive impairment. Any score of 24 or more (out of 30) indicates normal cognition. Below this, scores can indicate severe (≤9 points), moderate (10-18 points), or mild (19-23 points) cognitive impairment. Participants with lower MMSE scores (<10) will be removed from the study.
This study aims to evaluate the effectiveness and cost-effectiveness of CST-ES, the Spanish adaptation of Cognitive Stimulation Therapy (CST), to improve cognition and quality of life in people with mild to moderate dementia. The evaluation will be conducted as a pragmatic multicenter randomized controlled clinical trial. Participants will be randomized to receive 7 weeks of CST-ES followed by 24 weeks of maintenance CST-ES (intervention group) or to continue their usual treatment (control group).
This is a retrospective study of patients aged 65 years and older who underwent cardiac and aortic surgery between March 5, 2021 and October 12, 2022 in the operating room of Severance Cardiovascular Hospital to determine the impact of physical frailty as well as nutritional status, emotional dysregulation, and cognitive dysfunction on postoperative outcomes. Physical frailty will be determined by the Clinical Frailty Scale, handgrip strength, and nutritional status, cognitive dysfunction will be determined by the K-MMSE and K-MoCA administered at the preoperative interview, and emotional dysregulation will be determined using the SGDS-K. These were measured during the pre-anesthesia evaluation and only results from patients who agreed to be tested will be used. Nutritional status will be analyzed based on blood test values measured within one month of surgery.
Pragmatics of language refers to the set of abilities that allow one to use and interpret language according to context and, in general, to communicate effectively. Disorders in the pragmatics of language are prevalent in various clinical populations. They are a cause of social withdrawal and worse quality of life, both for patients directly affected and for their family members. Despite this, this type of disorder is rarely considered in neuropsychological assessment and rehabilitation. This study's objective is to characterize pragmatic deficits in various neurological populations, allowing for the most accurate diagnosis possible and leading to the planning of personalized and effective Rehabilitation Plans.
Minimally processed animal protein is a premier source of essential macro and micronutrients in the diet and is important, especially to older adults who are at increased risk of nutritional deficiency and age-related physiological changes. Our central hypothesis is that adding lean animal protein within a dietary guideline-based diet will enhance nutrient adequacy and attenuate markers of cognitive decline. This is a retrospective study leveraging samples collected from the feeding trial NCT05581953. PI for both studies are the same.
Patients with mild cognitive impairment aged 50-80 years old were recruited in Shiyan City, Hubei Province, and divided into intervention group and placebo group. They were given yeast β-glucan capsules and starch capsules, respectively, for 6 months, in order to explore whether yeast β-glucan can improve cognitive function of patients with mild cognitive impairment by regulating gut microbiota and its metabolites.
This is a single site, randomized exercise trial with individuals at least 50 years of age living with HIV who experience suboptimal cognition. The overall goals of this proposal are to determine whether 12 weeks of structured high-intensity interval training (HIIT) can overcome vascular and cognitive impairments (Aim 1) to a greater extent than continuous moderate exercise. Additionally, investigator will seek to identify barriers to engagement in exercise and the participants' perceptions of the study and exercise interventions (Aim 2). This study will enroll 60 participants in Birmingham, Alabama. Data collection will occur at each visit, with baseline data collected at the initial visit with a 3-month follow-up occurring following completion of the intervention.
The purpose of this study is to evaluate the efficiency and safety of a digital therapeutics(ET-101) for mild cognitive impairment (MCI). This is a randomized, sham-controlled, assessor-blinded, 24-week parallel study. 100 MCI patients will be randomly assigned to two groups. The control group will be provided with a sham device.
