Filter by:We will use cognitive exams, perceptual tasks, brain imaging, peripheral psychophysiology, and surveys to investigate the persisting effects of psilocybin on cognition, predictive coding, and affect in healthy older adults. We will measure changes in these measures by comparing baseline to one-week and one-month post-treatment. Participants will be randomly assigned to receive a dose of psilocybin in a range from microdose to moderate-to-high dose. Dose response will be assessed. Anatomical magnetic resonance imaging (MRI) and diffusion weighted imaging (DWI) will be used to assess changes in brain structure, while functional magnetic resonance imaging (fMRI) will be used to quantify changes in functional brain activity. We will assess whether changes in these brain measures underlie observed changes in cognition, predictive coding and affect.
Background: Aging leads to an alteration in the immune response, characterized by a chronic inflammatory state, and a progressive decrease in muscle quantity and quality, a situation that increases in women and in the presence of obesity. With respect to muscle quality, intramuscular infiltration of adipose tissue has been considered a relevant parameter, involved in the relationship between aging-obesity-inflammation. As a therapeutic strategy, physical training with resistance exercises (or also known as strength training) has been shown to be effective in increasing skeletal muscle mass in this age group. However, its role on muscle quality in normal-weight versus obese older women has not been fully addressed. Hypothesis: A 12-week resistance exercise training program is effective in improving muscle quality, immune response and physical performance in normal weight and obese older women. In addition to the above, the investigators hypothesize that women with obesity will present greater baseline alterations, so the percentage of change will be higher compared to older women with normal weight after the training program. Goals: The primary aim of this study is to evaluate the effects of a 12-week resistance exercise training on muscle quality (infiltration of intramuscular adipose tissue), immune response and physical performance in older women between 60 and 79 years of age with obesity compared to older women with normal weight of the same age range. Methodology: The present clinical trial will consider 2 groups of older women between 60 and 79 years old: normal weight (BMI=18.5 to 24.9 kg/m 2 and % fat <25.9) and obese (BMI =30 to 39.9 Kg/m 2 and fat % >32). Participants will perform 12 weeks of training with resistance exercises 3 times a week. Before and after training, intramuscular infiltration of adipose tissue (echogenicity) will be measured by ultrasound, followed by aspects of muscle architecture (muscle thickness, penile angle and fascicle length) and functional parameters of muscle quality (maximum strength determined by 1 repetition maximum-1RM, maximum voluntary isometric strength of knee extensors through a lower limb force and power transducer). Finally, fasting blood samples will be obtained (immune response) and physical performance, body composition, physical activity level, and quality of life will be evaluated.
Computer games are increasingly utilized as tools for studying cognitive skills, aging, individual differences, and development. They offer a unique advantage by presenting challenges that more closely mirror the complexities and demands of everyday tasks compared to traditional laboratory experiments, clinical tests, and standardized assessments. Our team took an innovative step in this direction by developing a suite of tablet-based games, titled VibrantMinds. These games, varying in type, are designed to measure diverse cognitive indicators, acting as proxies for assessments typically conducted using paper-and-pencil tests in clinical settings. VibrantMinds games have been specifically crafted to be user-friendly and engaging for older adults, including those with dementia. Our studies have shown that these individuals not only find the games accessible but also exhibit measurable improvement in gameplay, suggesting potential benefits for cognitive skill training. Building on this foundation, we are now poised to conduct an in-depth investigation into the actual effectiveness of serious computer games (SCGs) for cognitive enhancement and their application in real-world settings for older adults. This next phase of research will leverage the VibrantMinds platform to carry out studies aimed at validating software-defined indicators of cognitive function and measuring the impact of game-based interventions on cognitive abilities, health-related quality of life, and other significant real-life outcomes. The anticipated results promise to expand our understanding of the potential for new technologies in cognitive assessment and intervention. Moreover, by employing machine learning analysis of the data collected through VibrantMinds, we aim to develop a taxonomy that correlates game complexity and player performance with conventional clinical instruments for assessing cognitive status and functioning.
Population ageing is a global problem. With ageing, involutionary changes and multimorbidity increase, leading to limitations in the performance of daily activities and disability. Proposed by the World Health Organisation (WHO), the geriatric core set is a set of categories of the International Classification of Functioning, Disability and Health (ICF) that allows for a comprehensive assessment of a person of geriatric age. In Poland, the geriatric core set has not yet been adapted and validated. Therefore, the aim of this study is the cultural adaptation and validation of the Polish version of the ICF-based categorical profile for the assessment of older people.
The primary objective of this clinical trial is to assess the clinical efficacy and safety of the Buyuan Zhixiao Formula in treating elderly patients with diabetes and multiple metabolic disorders exhibiting symptoms of renal deficiency and blood stasis. Furthermore, this study aims to intervene in high-risk factors to prevent arteriosclerosis and to investigate the clinical efficacy of the Buyuan Zhixiao Formula in the prevention and treatment of cognitive impairments. The main questions it aims to answer are: 1. What are the clinical effects of Buyuan Zhixiao Formula, including lowering blood sugar, lowering blood pressure, lowering lipids, and treating obesity? 2. Can Buyuan Zhixiao Formula improve cognitive impairment in diabetes? Researchers compared Buyuan Zhixiao Formula with a placebo (a drug that looks similar but contains only 10% of the active ingredients) to see if the drug Buyuan Zhixiao Formula can treat elderly people with diabetes and multiple metabolic disorders. Participants will: 1. Take the drug Bu Yuan Zhi XiaoFormula or placebo every day for 6 months；Follow-up for 6 months； 2. Check fasting blood sugar and 2-hour postprandial blood sugar every month; check HbA1c, blood lipids, vascular function, and cognitive impairment serum markers every 3 months; 3. Conduct scores on TCM symptoms, cognitive ability, nutritional status and other scales and adverse events; 4. Urine and serum samples were collected before and after treatment;

The goal of this observational study is to learn about current practices for the acute neuropsychiatric management of older adults during emergency department (ED) visits. Researchers will compare current standard of care practices with implemented guideline practice to see if standardized medication guidelines help reduce the usage of antipsychotics and/or benzodiazepines during acute presentations. The main questions this study aims to answer are: - How many older adults are receiving antipsychotics or benzodiazepines during emergency department visits? - Why are older adults receiving antipsychotics or benzodiazepines during emergency department visits? - How many older adults who receive antipsychotics or benzodiazepines during emergency department visits have an underlying cognitive or movement disorder? - What effects does administration of antipsychotics or benzodiazepines during emergency department visits have on patient outcomes in older adults and adults with neurocognitive disorders? - Does implementation of standardized medication guidelines help reduce the usage of antipsychotics and/or benzodiazepines during acute presentations?
The purpose of the study is to compare the effectiveness of Divomed in organising complex hospital discharges with a conventional organisation. Effectiveness will be assessed by reducing the length of stay of patients in geriatric short-stay care.
The goal of this quasi-experimental study using a pre and post test design is to learn about the effect of participating in an exercise program with hydraulic exercise equipment on fall risk in the older adult population. The main questions it aims to answer are: - Does the use of hydraulic exercise equipment decrease fall risk in older adults? - Does the use of hydraulic exercise equipment improve function in older adults? Participants will be evaluated pre and post intervention for strength, fall risk using Berg Balance Scale, Tinetti Balance and Gait Assessment, Timed Up and Go, and functional ability using the Lower Extremity Functional Scale. Participants will engage in an exercise program using 5 different pieces of hydraulic exercise equipment (Frei FACTUM® novus II line) 2x/week for for 6 weeks for 30-45 minutes each session. The equipment uses concentric movements only and works agonist and antagonist muscles with each machine (IE: push and pull, both concentric).
The earth's climate is warming, and the number of heat waves has increased in recent years. At the same time, the number of adults over the age of 65 is growing. Humans sweat and increase blood flow to the skin to cool their body when they get hot. Older adults do not do this as well as young adults. This makes it harder to safely be in warm and/or humid conditions. It is important to learn about cooling strategies for older adults to safely be in warm and/or humid conditions. There is compelling evidence that intermittent hand and forearm cold-water immersion effectively reduces the rise of core temperature during heat stress in older adults. However, it is still unknown if this is an effective cooling strategy for older adults. Furthermore, our laboratory has shown that folic acid supplementation improves blood flow responses in older adults. This may be beneficial to older adults during heat stress.
