Filter by:The goal of the Dortmund Vital Study is to validate previous hypotheses and to generate and validate new hypotheses about the relationship of ageing, working conditions, genetic makeup, stress, metabolic functions, cardiovascular system, immune system, and mental performance over the lifespan with a focus on healthy working adults. The Dortmund Vital Study is a multidisciplinary longitudinal study involving the Departments of Ergonomics, Immunology, Psychology and Neurosciences, and Toxicology of the Leibniz Research Centre for Working Environment and Human Factors at the TU Dortmund (IfADo) in Dortmund, Germany, as well as several national and international cooperation partners.
This study is a phase III Randomized Clinical Trial, prospective, placebo controlled of 12,268 subjects with low to moderate risk of stroke followed by 3 years in 60 Primary Health Care Units in Brazil. The units will be randomized (clusters) to use or not the approach of community health workers with the Stroke Riskometer. After, patients will be randomized to receive the polypill (valsartan 80 mg, amlodipine 5 mg and rosuvastatin 10 mg) or placebo (dose adjustment of amlodipine 2,5 for patients with adverse events). The purpose is to test whether a polypill alone or in combination with lifestyle modification will reduce the incidence of stroke and cognitive impairment in this population.
Alzheimer's disease (AD) clinically characterized by the cognitive impairment and lowering of various functional abilities lead to staggering costs and suffering, which are particularly related to the social impacts of caring for increasingly disabled individuals. Some of these changes can be almost undetectable in the early stages of the disease, worsening over time often and at a varying rate of progression in different people. The traditional clinical scales or questionnaires such as ADCS (Alzheimer's Disease Cooperative Study) - ADL (Activities of Daily Living) for detecting such functional disabilities are typically blunt and rely on direct observation or caregiver recall. Digital technologies, particularly those based on the use of smart phones, wearable and/or home-based monitoring devices, here defined as 'Remote Measurement Technologies' (RMTs), provide an opportunity to change radically the way in which functional assessment is undertaken in AD, RMTs have potential to obtain better measurements of behavioral and biological parameters associated with individual Activities of Daily Living (ADL) when compared to the current subjective scales or questionnaires. Divergence from normative ADL profiles could objectively indicate the presence of incipient functional impairment at the very early stages of AD. Therefore, the main hypothesis of this study is that RMTs should allow the detection of impairments in functional components of ADLs that occur below the detection threshold of clinical scale or questionnaires.
This study is designed to assess the feasibility that individualized reminiscence-based virtual music therapy sessions can enhance autobiographical memory, mood, and cognition in patients with mild cognitive impairment (MCI) or mild dementia due to Alzheimer's Disease (AD). 60 patients with MCI or mild dementia due to AD will receive two 30 minutes reminiscence-targeted virtual music therapy interventions per week for 8 weeks (a total of 16 sessions). Participants' (or supported by the study partner) self-reported and measurable outcomes including cognitive, anxiety, quality of life, and autobiographical memory will be assessed before and after the 8-week course of treatment. Blood-oxygenation level-dependent (BOLD) in functional magnetic resonance imaging (fMRI) will also be also measured before and after the 8-week course of treatment.
The aim of this study is to investigate the effect of cognitive training combined with physical exercise on cognitive function, physical performance and frailty indicators in the hemodialysis population.
A mild cognitive impairment was observed in 50% of cochlear implant candidates aged 65 years and over, compared to 5-19% in general population. No studies analysed cognition in patients younger than 65 years. The aim of our study was to compare cognitive function between patients with severe and profound hearing loss and patients with normal hearing in patients aged 45 to 64 years.
Background: There is a need for standardized interventions in community rehabilitation that can improve everyday task performance for older adults with cognitive challenges after acquired brain injury. Older adults are often excluded from research due to strict inclusion criteria. It is critical for a sustainable health service system that these patients are empowered and reach their maximum level of independence. The Perceive, Recall, Plan and Perform System (PRPP) of Intervention can be applied by Occupational Therapists (OT) for clients with cognitive challenges to enhance mastery of needed or desired everyday tasks. There is no current evidence for the effectiveness of this intervention for this population. Purpose: A clinical trial to investigate the effectiveness of the PRPP intervention for older persons with cognitive impairments after brain injury in the context of community-based rehabilitation. Method: In PRPP intervention the OT uses systematically instructions in task training to support a client to use cognitive strategies efficiently. The everyday tasks used for training should be valued by the participant and useful in their rehabilitation. The tasks could include different parts of morning routines, simple or complex meal planning or preparation, use of cell phone, leisure activities, or other household and community activities. At best the skills are generalized throughout all everyday activities, and the OTs' role as a cognitive mediator fades as participants internalize the strategies. The participants receive PRPP intervention 3 times a week for 3 weeks, every session last for 45-60 minutes. The participants' task mastery and cognitive strategy use will be measured at least 5 times in each phase: baseline, intervention, after the intervention, and 4 weeks after the discharge from rehabilitation. The measurement scores at baseline act controls and are therefore compared with the other phases for the same participant. The same procedure will be repeated for the other participants, but then with a staggered intervention phase. A staggered intervention phase acts as a control between participants and allows to see if changes occur only when the intervention is introduced. Implications for practice: The investigators assume that this systematic intervention will improve everyday task performance, and will in turn contribute to empowerment and independence of older adults with cognitive challenges after brain injuries.
The purpose of this study is to see whether programs that include both a patient and their spouse or a patient and family caregiver (known as a dyad) are helpful for families in which one member of the dyad has cancer and mild memory difficulties and/or concerns. Participant and their spouse or participant and their family caregiver will have six, 60-minute video-conference sessions which will be scheduled at their convenience. The investigator will loan participants a tablet computer (iPad) to use for videoconferencing and train the participant in its use. Participant and their spouse or participant and their family caregiver will complete three assessments - one before starting the sessions, one after the sixth session, and one after 1 month. Each assessment will include surveys, which the participant will complete separately from their spouse or family caregiver. For most people, it will take upwards of 2 - 4 months to complete this study
The overarching aim is to develop and deploy a multidomain intervention delivered on a mobile application to help middle-aged to older adults reduce their risk for dementia by improving a set of modifiable lifestyle risk factors associated with cognitive decline/dementia. This registration concerns the Pilot Feasibility study which examines different aspects of feasibility in a small-scale randomized pilot study, before implementing an efficacy study on a larger sample. A secondary objective is to determine whether the program can result in a larger improvement on risk factors (measured with Behavioural Risk outcomes) compared to a control intervention. It is expected that persons enrolled in the Luci program show larger change in Behavioural Risk outcomes than those enrolled in the comparator condition.
The purpose of this study is to explore the long-term consequences of neuroimaging and perceived cognitive dysfunction in obstetrics posterior reversible encephalopathy syndrome.
