Filter by:With population aging, the number of older persons with cognitive impairments increases. Literature support the effectiveness of a lifestyle approach to promote the health of persons with cognitive impairment, as well as a Lifestyle Redesign intervention to improve the general health and quality of life of frail older adults. The investigators propose to combine a multi-modal cognitive intervention and lifestyle redesign approach to improve the cognitive health of older persons with cognitive impairments.
The Digital Cognitive Multi-domain Alzheimer's Risk Velocity (DC MARVEL) study is a 2-year randomized controlled trial on dementia prevention. The purpose of this study is to determine the effect of a digital cognitive health program on dementia risk, cognitive function, and general health outcomes in middle age to older adults compared to a control group that receives health education.
Older women with cardiovascular disease (CVD) are at greater risk for memory loss, an important public health issue due to the negative effects to quality of life and health care costs. This research will be the first to examine the independent and combined effects of a lifestyle physical activity intervention and cognitive training on memory performance and memory-related serum biomarkers in this vulnerable population. The investigators will incorporate a practical lifestyle approach that can be delivered in the home and community settings to prevent or delay memory loss in older women with CVD.
Transcranial magnetic stimulation (TMS) is a noninvasive brain stimulation technique that is increasingly used for a growing number of research and clinical applications.Typically, this transient magnetic field is focally applied with a figure-of-eight coil that is carefully placed on the surface of the scalp over a targeted stimulation site. Patterned repetitive TMS (rTMS), such as theta burst stimulation (TBS) can produce long-lasting effects on neural activity and behavior beyond the stimulation period (Chou et al., 2015a; Fitzgerald et al., 2006). In general, high frequency (> 5 Hz) rTMS and its newer version, intermittent theta burst stimulation (iTBS), facilitate cortical excitability, whereas low frequency (about 1 Hz) rTMS and continuous theta burst stimulation contribute to opposite effects (Pascual-Leone et al., 2000; Huang et al., 2005; Wassermann and Zimmermann, 2012).Careful manipulation of the parameters comprising these patterned rTMS pulse trains can induce neuroplastic changes that resemble either long-term potentiation (LTP) or depression (Chen et al., 1997; Pascual-Leone et al., 1994). Early studies targeting the motor cortex helped elucidate which rTMS parameters promote particular responses and their neurophysiological underpinnings (Klomjai et al., 2015). In recent years, rTMS has been closely investigated to evaluate its potential to modulate cognitive functions in Alzheimer'sdisease (AD) and mild cognitive impairment (MCI). As compared to conventional excitatory rTMS protocols, iTBS leads to comparable effects with similar number of pulses but considerable shorter duration and lower intensity of stimulation (Bakker et al., 2015; Rossi, Hallett, Rossini, Pascual-Leone, & Safety, 2009). Recent literature also suggest that TBS has lower rates of reported adverse event (AE) compared to rTMS (Najib & Horvath, 2014). Therefore, iTBS is assumed to modulate cognitive function in people with cognitive impairments.
This trial investigates the effect of a chicken extract supplement and a peptide supplement on cognitive function and potential mechanisms of action of cognitive decline during ageing, among non-demented elderly adults using a three-arm, randomized, placebo-controlled clinical trial design.
The objective of this trial is to demonstrate early proof-of-concept for My Healthy Brain, an 8-week group program that directly targets multiple lifestyle factors associated with brain health and prevention of cognitive decline. The investigators will explore the feasibility, acceptability, and effect sizes of improvement in primary lifestyle outcomes as well as secondary outcomes of self-determination and subjective well-being.
This study investigated the effect of acute multiple joint, structural barbell resistance exercise on information processing speed and conflict-related neural activity in older adults via a crossover, sham control, randomized control trial.
A randomised control study of metformin in people with mild cognitive impairment and without diabetes mellitus to determine effects on cognitive decline and neuroimaging over 3 years.
Understanding how to delay age-related physical and mental declines is an issue for aging research. It has been shown that isolated aerobic, coordination and cognitive training improve brain functions and cognitive performances. Moreover, the combination of them leads to greater effects. Different combination modalities are possible: training programs demanding cognitive resources within the activity performed in a natural environment like Nordic Walking (or Tai chi, Dance...); or as in a conceptually-grounded circuit training where training components are systematically combined and their intensity controlled. The aim of this study is to compare three training programs: a Nordic walking one (NW), and two conceptual grounded, circuits training (CT-c; CT-fit). CT-c implemented by dual-task (DT) exercises, while CT-fit characterized by cognitive charge embodied in the movements through the use of technology. An improvement in physical, motor, and cognitive functions is expected by all three groups. However, our primary hypothesis is that the CT-fit will impact executive functions more. 45 healthy independent living community dwellers participants aged 65 to 80 will be recruited. Participants will be included after a general medical examination (geriatric screening and cycle-ergometer maximal effort test). The main exclusion criteria are signs of cognitive impairment, (MMSE <26/30), and physical impairments. Participants will be randomly divided into the 3 groups (NW, CT-c, CT-fit): The training program will last 8 weeks, 1 hour 3 times a week. Pre and post-tests will include cognitive assessment (MoCA; TMT; Stroop task, Happy Neuron™ working memory test, Rey Complex Figure copy task and dual-task capacities through the DT-OTMT); motor fitness assessment (Bipedal upright standing, Unipedal balance test, walking speed and size of the base of support, Timed Up & Go, Chair sit and reach test and Four square stepping test) and physical assessment (10 m incremental shuttle walking test, maximal handgrip force, 30s chair rise stand). Improving cognitive functions by adding new technology embodied in a systematically combined training (exergame), would result to be the best solution to optimize training for aging people.
