Filter by:This study aims to determine the efficacy of digital Behavioural Therapy for Insomnia (dBTi) compared to online sleep health education (control) at reducing insomnia symptom severity (Insomnia Severity Index: ISI) in older adults (50+ years) with subjective cognitive impairment from baseline compared to week 8.
This study is to elucidate the possible mechanisms of SSE by examining brain activation differences between SSE patterns and usual walking, as well as the relationship between brain activity and SSE performance, between cognitive function and SSE performance, and between physical performance and SSE performance in frail elders with MCI.
Adults with coronary artery disease (250 patients) undergoing cardiac surgery participated in the study. The aim is to investigate short-term and long-term cognitive outcomes and the patterns of organization of functional brain systems in ischemic brain damage using high-resolution electroencephalography, domain-specific assessment of cognitive status and analysis of markers of a neurovascular unit (neuron-specific enolase, brain neurotrophic factor).
PROMED-EX is a single-blind, parallel group randomised controlled trial to determine the effect of a PROtein enriched MEDiterranean diet (PROMED) in comparison to a PROtein enriched MEDiterranean diet and EXercise (PROMED-EX) intervention, or standard care on the nutritional status and cognitive performance of older undernourished adults with subjective cognitive decline.
Neurocognitive decline is a health issue that is associated with ageing. It is often irreversible from the onset. The concomitant costs of neurocognitive decline could be potentially exponential if left unchecked. Therefore, there is a need to be able to delay the onset of age-related neurocognitive decline or possibly avoid it altogether. Previous studies have shown that there is a strong positive relationship between the fitness of neurocognitive function and cognitive training. More interestingly, recent studies also suggest that combining cognitive training with physical activity may result in a better outcome for neurocognitive function as compared to only cognitive training. Anchoring on the findings of those studies, the investigators aim to develop and evaluate the efficacy of a novel personalized multimodal brain computer interface (BCI) cognitive and physical training system for neurocognitive protection and enhancement in older adults. The current study employs a three-arm randomized-controlled trial approach. The investigators hypothesize that participants in the multimodal cognitive and physical training (mBCI) group will perform significantly better than the cognitive training-only BCI (nBCI) and active control (AC) groups on the Repeated Battery for the Assessment of Neuropsychological Status (RBANS) after an initial high-intensity 36 training session period from pre- to 12 weeks post-intervention. The investigators also hypothesize that the mBCI group will perform significantly better on the RBANS than nBCI or AC groups after the consecutive high- and low-intensity periods from pre- to 24-weeks post-intervention.
This study will compare two approaches to cognitive rehabilitation in adults with stroke with persistent, mild to moderate, cognitive impairment. Both approaches will feature a web-based computer "game" that trains cognitive processing speed, i.e., how quickly individuals process information that they receive through their senses. This training is termed Speed of Processing Training (SOPT). One approach will add (A) in-lab training on everyday activities with important cognitive components and (B) procedures designed to transfer improvements in cognition from the treatment setting to everyday life. This approach is termed Constraint-Induced Cognitive Therapy (CICT). The other approach will add (A) in-lab training on relaxation, healthy nutrition, and healthy sleep and (B) procedures designed to promote integration of these lifestyle changes into everyday life. This approach is termed Brain Fitness-Heath Education Lifestyle Program (BF-HELP). Both CICT and BF-HELP will involve 35 hours of training. Ten 1-hour sessions of SOPT will be scheduled in the home with training conducted independently by participants. Ten 2.5 hours of in-lab, face-to-face, therapist directed sessions will be scheduled. These sessions will feature a brief period of SOPT; the bulk of the sessions will be committed to in-lab training on the target behaviors and the procedures designed to promote transfer of therapeutic gains to daily life; The set of the latter procedures is termed the Transfer Package. To accommodate the demands of participants' other activities, training sessions will be permitted to be scheduled as tightly as every weekday over 2 weeks or as loosely as every other weekday or so over 4 weeks. Family caregivers in both groups will also receive training on how to best support participants in their therapeutic program. The study will also test if there is an advantage to placing follow-up phone calls after treatment ends. The purpose of the calls will be to support transition of any behavioral changes achieved during treatment into everyday life on a long-term basis. Participants will be randomly assigned to the interventions. Testing will happen one month before treatment, one day before treatment, one day afterwards, and 6- and 12-months afterwards. Outcomes measured will include cognitive processing speed, cognitive function on laboratory tests, and spontaneous performance of everyday activities with important cognitive components in daily life.
Every three seconds someone in the world develops dementia. There are over 50 million people worldwide living with dementia and by 2030 this figure is expected to reach 82 million. Besides time-consuming patient investigations with low discriminative power for dementia risk, current treatment options focus on late symptom management. By screening brain connectivity and dementia risk estimation in people affected by mild cognitive impairment, the European Union (EU) funded AI-Mind project will open the door to extending the 'dementia-free' period by offering proper diagnosis and early intervention. AI-Mind will develop two artificial intelligence-based digital tools that will identify dysfunctional brain networks and assess dementia risk. Personalised patient reports will be generated, potentially opening new windows for intervention possibilities.
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.
