Filter by:Aging is characterized by low-grade inflammatory state, supported by impairment oxidative balance and endocrine changes, leading to changes in: body composition, such as decrease in lean body mass and increase in adipose tissue; resting metabolic rate; immune function; cognitive impairment. According to the Academy of Nutrition and Dietetics all subjects over the age of 60 should be able to access to adequate nutrition and appropriate nutritional services. In order to ensure healthy aging and to reduce effects of specific diseases, recommendations are needed for illness and disability in this population, as well as adequate physical activity and specific support programs, culturally accepted. The aim of this study is to evaluate eating habits in term of food consumption, health state and lifestyle in a sample of free-living elderly over the age of 65, living in Milan and surroundings. In particular, profiling of the elderly population is performed using a survey in which information are collected on methods, contexts, time and ability to buy, prepare, consume and dispose of and recycle food. Eating habits and knowledge about food are detected through the analysis of food consumption frequencies, and lifestyle by assessing the level of physical activity, quality of sleep, smoking habit. Weight status and health status are evaluated through anthropometric measurements, body composition (bioelectrical impedance) and strength test. Other information relating to social participation and other socio-demographic variables (age, gender, family composition, socio-economic status) are collected to have a completed profiling of target population. Achieved results will help us to identify factors on which acting to ensure healthy aging and counteract inflammaging, the chronic low-grade systemic inflammation characteristic in the aging process. Moreover, the study allows increasing the knowledge related to the needs and requirements of the target population to determine a good food policy and to increase the elderly empowerment.
To evaluate the validity and reliability of Turkish version of the Oxford Participation and Activities Questionnaire (Ox-PAQ) for Turkish older population. Following the translation protocol of the Ox-PAQ, Short Form-12, Katz Index of Independence in Activities of Daily Living Scale, The Five Times Sit to Stand Test were administered to 230 older people. End of this study, occupational therapists, physiotherapists can use the it to assess activity and participation level of older people living in community
In the next three decades, the world's population over 60 years old is expected to more than double its size. Even in the absence of an obvious pathology (i.e., healthy aging), advancing age is typically associated with a progressive decline in cognitive performance. Although pathophysiological changes in age-related neurodegenerative disorders have received much attention over the past years, far less is known about the neural processes affecting cognition in healthy ageing. One of these postulated processes is neural dedifferentiation (i.e., a decrease in neural selectivity, by which neural representations of processed information become less univocally distinguishable), possibly accompanied by the recruitment of additional cortical areas in the healthy aging brain. To date, these processes have been extensively studied on the neural level, yet their functional significance for cognitive behaviour remains largely unclear. This project will investigate neural dedifferentiation and its relationship to cognitive performance in the healthy aging brain. To this end, the investigators will use a combination of state-of-the-art technologies including simultaneous transcranial magnetic stimulation (TMS) and high-density electroencephalography (hd-EEG) as well as diffusion tensor imaging (DTI). Perspectives include a better understanding of the relationship between neurophysiological mechanisms and cognitive performance in the healthy aging brain.
In this study, high-definition dual-site transcranial alternating current stimulation (i.e., non-invasive brain stimulation) will be applied to boost the fronto-parietal network during a bimanual coordination task in healthy young and older adults. Previous studies indicated that this network is important in initial motor learning, possibly through its role in spatial working memory. Therefore, stimulation will be applied during both a pure spatial working memory test, and during a bimanual coordination task. It is also shown that healthy older adults do not engage spatial working memory brain regions during motor learning, which is related to worse motor learning. Therefore, the investigators will investigate whether this type of stimulation can improve bimanual motor learning in healthy older adults.
The study examines the effect of cocoa flavanols, red-berries anthocyanins or a combination of both on markers of cardiovascular health and cognition.
The broad goal of this research project is to improve the prediction of falls in patients with Parkinson's disease (PD) through a comprehensive multidisciplinary approach that includes longitudinal measurements of walking, cognitive and functional performances. PD is a life-changing disorders affecting one million Americans, with more than 60,000 new cases reported every year. Within 3 years of diagnosis, more than 85% of people with clinically probable PD develop gait problems, which in turn lead to falls resulting in serious injury and reduced quality of life. There is a pressing need to identify fall risk factors before the occurrence of the first fall, and to better understand behavioral and cognitive changes leading to falls in PD patients.
L-citrulline is found naturally in watermelon. Recently interest has increased for this amino acid due to potential health benefits. Notably, L-citrulline has the potential to lead to dilation of blood vessels due to its involvement in the production of nitric oxide. The study will be an acute single blind, randomised controlled, crossover intervention study in healthy, young volunteers. Participants receive either the test watermelon drink or control drink (water). Blood samples and vascular measures (by a single-cuff based method) will be measured at baseline. Vascular measures will be repeated at 15-minute intervals between 0-2 hours and a second blood sample will be drawn at 1.5 hours to coincide with the estimated peak plasma L-citrulline. Citrulline, arginine and nitric oxide metabolites will be measured in the blood samples.
Thirty-three healthy elderly people, who were classified into two age groups, participated in this study. All participants had not practiced yoga before and were asked not to perform any sports activities while the research was ongoing. In the experimental group, participants (n = 18) had to participate in 10 weeks of yoga classes. In the control group, participants (n = 15) did not perform any exercises or other changes in their daily living life. Experimental measurements: Brunel, PSS-14 and HAD questionnaires
The goal of this study is to test efficacy and safety of person-centered, culturally-informed protocols for disclosure of different combinations of Alzheimer's dementia risk factors. Building on the results from a federally-funded assessment of preferences and needs of racially diverse participants and their respective friends/family members, in regard to Dementia - Alzheimer's Type (DAT), we have produced protocols for communication of DAT risk, with attention to specific adaptations in style or content based on individual factors and preferences. These protocols allow for communication of risk based on clinical history and diagnosis, structural neuroimaging, apolipoprotein-E status, and amyloid and tau burden on positron emission tomography. In particular, protocols specify (a) effective methods of communicating risk conferred by each data source, (b) information designed for patients versus informants, (c) psychoeducation needs, and (d) resource/support needs. We will recruit a randomly-selected subset of 10 dyads (including 5 participants who are Non-Hispanic African-American, 5 participants who are Non-Hispanic White) from the Stage I sample to whom we will develop and implement personalized DAT risk disclosure protocols. We will provide preliminary information on the effectiveness of these protocols in terms of patient/co-participant comprehension and recall of feedback provided, and initial changes in mood or behavior immediately following and shortly after risk disclosure sessions.
The overall goal is to characterize the acute exercise response as it relates to brain glucose metabolism in aging and Alzheimer's Disease (AD). The study team will also examine lactate metabolism, relationships with cognition, and the effect of exercise intensity.
