Filter by: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.
Dementia caused by Alzheimer's disease affects approximately 5.6 million adults over age 65, with costs expected to rise from $307 billion to $1.5 trillion over the next 30 years. Behavioral interventions have shown promise for mitigating neurodegeneration and cognitive impairments. Sleep is a modifiable health behavior that is critical for cognition and deteriorates with advancing age and Alzheimer's disease. Thus, it is a priority to examine whether improving sleep modifies Alzheimer's disease pathophysiology and cognitive function. Extant research suggests that deeper, more consolidated sleep is positively associated with memory and executive functions and networks that underlie these processes. Preliminary studies confirm that time-in-bed restriction interventions increase sleep efficiency and non-rapid eye movement slow-wave activity (SWA) and suggest that increases in SWA are associated with improved cognitive function. SWA reflects synaptic downscaling predominantly among prefrontal connections. Downscaling of prefrontal connections with the hippocampus during sleep may help to preserve the long-range connections that support memory and cognitive function. In pre-clinical Alzheimer's disease, hyperactivation of the hippocampus is thought to be excitotoxic and is shown to leave neurons vulnerable to further amyloid deposition. Synaptic downscaling through SWA may mitigate the progression of Alzheimer's disease through these pathways. The proposed study will behaviorally increase sleep depth (SWA) through four weeks of time-in-bed restriction in older adults characterized on amyloid deposition and multiple factors associated with Alzheimer's disease risk. This study will examine whether behaviorally enhanced SWA reduces hippocampal hyperactivation, leading to improved task-related prefrontal-hippocampal connectivity, plasma amyloid levels, and cognitive function. This research addresses whether a simple, feasible, and scalable behavioral sleep intervention improves functional neuroimaging indices of excitotoxicity, Alzheimer's pathophysiology, and cognitive performance.
This is a randomized, controlled, pragmatic trial designed as a "type I hybrid effectiveness-implementation trial" that tests a hypertension program integrating a virtual Collaborative Care Clinic (vCCC), home blood pressure monitoring, and telehealth for lowering blood pressure (BP) in two health systems.
The KBASE2 is the second phase of the KBASE project, which consists of roll-over participants from the first phase of the KBASE as well as newly enrolled participants with varying degrees of cognitive functions (e.g. individuals with normal cognition, mild cognitive impairment, or AD dementia). In addition to the aims of the first phase of the KBASE, the KBASE2 will focus on new data collection and integrative analysis of the rich structural, functional, and molecular neuroimaging data in relation to whole genome sequencing and other -omics. Network analysis of disruption in brain connectivity in relation to clinical status and AD biomarker profiles also will be conducted.

Purpose: To compare esketamine and ketorolac separately and in combination to prevent postoperative pain and cognitive dysfunction after total knee arthroplasty
Residents living in long-term care (LTC) homes spend up to 75% of their day in sedentary, socially withdrawn situations which increases their risk for depression, dementia, decreased functional status and increased care costs. Physical activity is an accepted intervention to improve the physical health, cognition, and well-being of older adults. Moreover, systematic reviews have found that exergaming (i.e. physical activity gamified with technology) offers physical, cognitive, and social benefits by means of dual-task activities that engage both motor and cognitive abilities. The effect of exergaming for older adults in LTC is less clear, as this population has greater health needs related to physical health conditions, cognitive impairment, and functional dependence. Given the increased global demand for LTC, there is a need to develop and assess innovative exergaming technologies that can support the physical and cognitive health of LTC residents. MouvMat is an exergaming technology intervention with an interactive digital gaming surface designed for older adults (OA) in LTC settings. Participants can play familiar games, like Simon or Bingo, by stepping on or tapping the surface with an assistive pointing device. Games can be played individually or with multiple players. LED lights on the surface provide an adaptive digital display and embedded pressure sensors respond to players' input. The investigators collaboratively designed a preliminary prototype with OA aged 65 and older in a pilot project. The overall objective of this proposal is to conduct a pilot RCT of the Mouvmat to evaluate the feasibility, acceptability and efficacy of the exergaming technology to improve the primary outcome of mobility, and the secondary outcomes of cognitive function and social isolation compared to a usual care control group receiving standard recreational programming by recreational therapists.
Following an initial consultation with a memory, resources and research centre (MRRC) doctor, a day hospital may be prescribed to carry out an assessment of cognitive disorders. Patients are then usually followed up in consultation at least once a year, in the framework of a new day hospital and/or consultations with a MRRC doctor.
The purpose of this study is to determine whether daily treatment with this new treatment approach, called COT would be effective in protecting the memory and brain regions of people who are already showing signs of memory loss.
