The present study aimed at investigating the effects of two different resistance training protocols — nonperiodized (NP) and daily undulating periodization (DUP) — on hemodynamic, morphofunctional and cognitive parameters of robust older women. Methods: Forty-two older women were randomized allocated into one of the three experimental groups: NP, DUP, and control group (CG). Evaluations of the hemodynamic, morphofunctional and cognitive parameters occurred before, during and after six months. The exercise groups performed the program of exercise twice a week over 22 weeks. In NP, the two weekly sessions were based on 3 sets of 8-10 repetitions at a difficult intensity. However, in DUP, a power exercise session based on 3 sets of 8-10 repetitions at a moderate intensity was added in the first session of the week.
Objectives: 1) To examine whether the real transcranial direct current stimulation (tDCS) group would perform better in the cognitive training (CT) intervention than the sham tDCS group and the CT group; 2) To determine if, as a consequence of the stimulation generated by the use of tDCS, there would be a transfer effect to other cognitive domains and to cognitive tasks in activities of daily living; 3) To investigate the time and spatial responses of tDCS on the brain cortex during and after tDCS application. Hypothesis to be tested: By applying anodal tDCS with the combination of a CT delivered via the use of tablet PCs in older adults at risk of MCI, it will enhance their cognitive task performance in CT and subsequently generalize to other cognitive domains as well, involving a transferability to cognitive tasks in activities of daily living. Design and subjects: A multi-centered single-blinded randomized controlled trial (RCT) with three groups (CT alone/Sham tDCS with the combination of a CT/ Real tDCS coupling with CT) The participants who will take part of this study will be older adults at risk of MCI Study instruments: tDCS, Ipad, Neuron Up CT Apps, EEG. Interventions: The intervention will last for 9 sessions (3 sessions per week for 3 weeks). Sham tDCS and real tDCS, will be combined with the same CT which is used in the CT group. During the experimental intervention, anodal tDCS will be placed on left dorsolateral prefrontal cortex (DLPFC) and cathodal tDCS on the contralateral deltoid muscle with the combination of a CT. During the experimental intervention, anodal tDCS will be placed on left dorsolateral prefrontal cortex (DLPFC) and cathodal tDCS on the contralateral deltoid muscle with the combination of a CT. Main outcome measures: Cognitive assessments, CT performance, EEG. In addition, delta and theta frequency suppression and alpha increment power under the anode electrode will be observed.
To study the correlation of POCD with olfactory function. To explore whether enhanced olfactory stimuli can reduce the risk of POCD as a preventive strategy.
With the nation's fastest growing demographic being adults over 65, one in every three seniors is estimated to die from Alzheimer's Disease (AD). The strong correlation between AD and age, combined with the exponential growth of this demographic, highlights the need for non-pharmaceutical treatment/prevention strategies. Research has established a relationship between moderate to vigorous physical activity (PA) and improved cognitive functioning. However, there is insufficient evidence to support this relationship at the lower end of the PA spectrum. Assisted living facilities (ALF) are an easy target for reducing SB, as many individuals in these facilities have various functional limitations and therefore cannot meet the recommended PA guidelines. Older adults are also the most sedentary population, with results showing over 8.5+ hours daily spent in SB. ALF typically provide meals, laundry services as well as housekeeping duties, leaving the residents very susceptible to large amounts of SB. The primary purpose of my study is investigating how reducing sedentary behaviour (SB) in ALF will affect Alzheimer's Disease Assessment Scale-cognitive scores among older adults aged 65 and older with mild-to-moderate cognitive impairment. I will also investigate its effects on physical functioning with the Timed Up and Go test (TUG) and quality of life with the Short Form 36 (SF-36) Health Survey. Participants will be prompted to take a 10-minute light intensity PA break at three different time points throughout the day, reallocating SB to any task equating to over 1.5 metabolic equivalents. Positive findings may encourage ALF to implement policies and procedures regarding SB.
This study evaluates the feasibility of enrolling and retaining older adults in a 15-week intervention that will implement six factors from early childhood experiences: individualized scaffolding (having a responsive teacher), forgiving environment (allowing the learner to make and learn from mistakes), growth mindset (believing that abilities can develop with effort), open-minded learning (exploring new experiences), serious commitment to learning (adopting a "learning" lifestyle), and learning multiple skills simultaneously. These six factors will be implemented via concurrent classes at the UCR Extension center (OSHER Lifelong Learning Institute).
The aim of the study was to analyze the effectiveness of a comprehensive cognitive remediation program (REHACOP) in the non demented elderly, obtaining improvements in cognition and functional skills. It was a longitudinal randomized controlled trial with three assessments: basal, post-treatment, and 12-month follow-up. Recruitment and enrollment were conducted between September 2012 and November 2016. All participants underwent a clinical interview and an extensive neuropsychological battery. Patients were randomized in an experimental and a control group. The groups were formed by a maximum of eight participants run by an experienced therapist. The experimental group received cognitive remediation for 3 months, 3 times per week, 60 minutes per session. The control group consisted of occupational group activities (reading the newspaper, drawing, singing or doing crafts) with the same frequency as the experimental group. Post-treatment assessment was carried out within the first week after completing the intervention. Finally, longitudinal follow-up at 12 months with neuropsychological assessments will be performed. Objective: To examine the efficacy of a comprehensive cognitive training program (REHACOP) to improve cognition, clinical symptoms and functional disability for the elderly.
This study will adopt a newly developed computer-based cognitive rehabilitation program targeting the encoding stage of memory. The aims of the study are: 1. To test the feasibility of conducting a newly developed computer-based cognitive rehabilitation program for healthy older adults, people with MCI and mild dementia. 2. To test the effectiveness of the newly developed program in improving cognitive function and enabling maintenance of occupational performance in healthy older adults, people with MCI or mild dementia. Using an iPad application, study participants will learn a memory encoding strategy to support completion of their daily activities. By implementing memory encoding strategies during the mild stages of cognitive decline, the project aims to prolong independence in functional performance. It is anticipated that adoption of the same memory strategies will enable maintain performance as they may experience ongoing cognitive decline.
Individuals of advanced age are at higher risk of cognitive deterioration.A single bout of aerobic exercise was found to improve cognitive functions. The aim of this study is to explore the effect of a single bout of balance and coordination exercise versus aerobic exercise on cognitive functions among elderly people.
The aim of this project is to study the safety and efficacy of anthocyanins in improving key dementia-related mechanisms and cognitive functioning in older people at risk for dementia. Secondary analyses will include a variety of biological measures, including biochemistry, imaging and cardiovascular measures.
