Filter by:The ACHIEVE Brain Health Follow-Up Study is a 3-year follow-up to the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) randomized study to determine the long-term effect of hearing intervention vs. successful aging/delayed hearing intervention on rates of cognitive decline and incident mild cognitive impairment or dementia.
The purpose of the study is to investigate the use of a special radioactive drug called 123I-MIBG and myocardial MIBG scintigraphy. This scan may be able to help determine who may have a certain kind of neurologic disorder called Lewy Body Disease. The overall purpose of this study is to correlate myocardial MIBG scintigraphy findings with clinical diagnosis. Myocardial MIBG scintigraphy imaging will be combined with other clinical, neuropsychological and neuroimaging findings to improve the prediction for underlying Lewy Body Disease.
This study aims to examine the effects and potential mechanisms of theta-burst stimulation (TBS) on cognitive function in individuals with mild cognitive impairment (MCI).
The research plan to enroll 15 simple snoring patients (apnea/hypopnea <5, control group), 30 severe OSA patients (apnea/hypopnea >30, treatment group), and 15 mild cognitive impairment patients (comparative group). All patients complete Mini-Mental State Examination, peripheral blood sample for plasma Aβ42, Aβ40, Aβ42/Aβ40, Tau, NfL; amyloid deposit in18F-florbetapir PET; and Taiwan smell identification test. Thirty severe OSA patients (AHI>30, treatment group) receive comprehensive upper airway surgery with/without bariatric surgery and repeat postoperative assessment in polysomnography and aforementioned examinations 1 year later.
Normal aging is associated with a progressive decline in cognitive functions, especially memory. This decline in cognitive function can negatively impact the quality of life of older adults. Although there are currently few possibilities to prevent and/or slow the signs of cognitive decline, both those associated with age and neurodegenerative pathologies, one of the non-invasive brain stimulation techniques that has gained attention in recent years is Transcranial Direct Current Stimulation (tDCS). tDCS is a technique based on the application of a low-intensity (< 2 mA) direct electrical current between two large-area electrodes placed on various surface areas of the head. Moreover, according to safety-related meta-analyses it is a very safe technique, without any major side effects, provided that internationally established safety protocols are taken into account in its application. This technique has recently been investigated as a potential treatment for both healthy elderly people and people with mild cognitive impairment and Alzheimer's disease in several cognitive variables, having shown encouraging results in working memory learning curves, modulation of plasticity and recognition tasks. This project aims to implement an intervention using transcranial direct current stimulation in healthy older adults, MCI and AD. The main objective is to test if there is an improvement in cognitive efficiency and if the changes are maintained over time (1 month). For this purpose, the effect of the technique will be studied on participants assigned to treatment and control groups, analyzing the possible modifications in the following cognitive variables: cognitive plasticity and learning potential, recognition and familiarity and false alarms.
Study is designed to screen psychological cognitive baseline and retention/improvement after weight loss surgery.
This project capitalizes on a natural experiment imposed by the COVID-19 pandemic in conjunction with an extensive set of cognitive, emotional, biological, and neuroimaging variables already collected at multiple time points in older adults participating in a clinical trial of exercise and mindfulness. This project will elucidate the effects of stress on cognitive function and emotional health in later life, including biological measures of Alzheimer Disease risk, stress, and aging, with the ultimate goal of discovering how to mitigate these effects, among older adults who have made and maintained a lifestyle change.
The global aging population is rising year by year. According to the result of Taiwan epidemiological survey, dementia has become the health issue in aging population. Mild cognitive function impairment may present years before dementia is diagnosed. Therefore early diagnosis of dementia at its Mild cognitive function impairment stage is beneficial for disease prevention and potentially delaying the deterioration of cognitive function impairment. Nutritional status includes a healthy diet, favor body composition and activity habits, which not only reduces the risk of nutritional metabolic diseases, but also has a direct relationship with delaying cognitive function impairment. The dietary quality index of Mediterranean-Dietary Approaches to Stop Hypertension Intervention for Neurodegenerative Delay diet (MIND diet) may prevent aging and positively associated with delaying dementia in elderly. However, the result in dietary quality index and delaying cognitive function impairment from current studies were still unclear. In additions, based on the differences in dietary patterns between Taiwan and Western countries, no current calorie and dietary nutrition recommendations. This cross-sectional study is to investigate the association between dietary quality index and nutritional status risk factors in cognitive function impairment patients and expected to develop an assessment tool for Taiwanese clinical nutrition strategies and applications.
The purpose of this research is to collect and compare electroencephalogram data from all stages of Alzheimer's disease from preclinical through severe dementia.
The corona virus disease 2019 (COVID-19), suddenly incepted in December 2019 in Wuhan, China, leading to one of the greatest health care emergencies of the last century. Acute exacerbation of the COVID-19 can develop to an ARDS in a significant proportion of hospitalized cases, leading to invasive mechanical ventilation requirement and in some cases even mandating use of extra-corporeal membrane oxygenation. Being a disease having affected up to 15'581'009 as of July 25th, with more than 635'173 deaths, the long-term repercussions are of foremost importance. Health care systems world-wide will be faced with the aftermath of COVID-19, and optimal understanding of the long-term progression of COVID-19 may aid in a better care of critically ill patients and enable specifically targeted rehabilitation programs to improve outcomes. Primary objective of this study is to assess the repercussions of COVID-19 induced critical illness on long-term functional status, quality-of-life, neuropsychology and cognition
