Filter by:The overall objective of the proposal is to examine the association between depression and the newly reported "motoric cognitive risk" (MCR) syndrome, which is a pre-dementia syndrome combining subjective cognitive complaint (i.e.; memory complaint) with objective slow gait speed, in the Canadian population, with the baseline assessment of the Canadian Longitudinal Study on Aging (CLSA). The Canadian and global population are continuously aging. Moreover, the number of individuals affected by dementia is on the rise. One good predictor of dementia is Motoric Cognitive Risk (MCR) syndrome. MCR syndrome is a highly prevalent, newly defined syndrome that combines slow gait and subjective cognitive complaint. Depression is also highly prevalent in the older population and can affect both cognition and gait. Thus, an overlap between MCR and depression is possible. Yet few studies have examined the association between MCR and depression, thus emphasizing the importance of further investigating this association. This project encompasses determining the association of MCR syndrome with depression in the Canadian context as a step to better understand MCR syndrome in Canada.
The study evaluates the association between the neurocognitive decline and falls.
The purpose of this international, multi-centre observational study is to describe perioperative cognitive changes (pre-existing neurocognitive disorder [NCD], postoperative delirium [POD] and Postoperative Cognitive Dysfunction [POCD]) up to five years after elective surgery in a mixed cohort. Measurements and definitions of cognitive outcomes will be based on current consensus and used for further harmonization in future clinical studies on perioperative cognitive trajectories. This is a feasibility approach to identify an effective screening procedure and estimate loss to follow up rates for the planning of future intervention studies. Data from this trial may also serve to facilitate and implement time effective cognitive screening and risk stratification concerning postoperative cognitive decline in the anaesthesiological preoperative assessment.
Cognitive Stimulation (CS) in the elderly, as a group intervention, shows benefits on the cognition and quality of life of people with neurocognitive disorder (NCD)(ie, dementia). The evidence of cognitive stimulation as an individualized intervention, conducted at home, by the caregiver is limited. The main objective of this trial is to evaluate the effectiveness of the Individual Cognitive Stimulation Therapy program - "Making a Difference 3 - individual Cognitive Stimulation Therapy (MD3), its acceptability and applicability by the dyad (people with NCD and their caregiver) in the Portuguese population. To achieve this purpose a pilot study will be conducted (randomized control trial), with two moments of evaluation - before the intervention of individual cognitive stimulation and after the intervention in both groups (Group 1 - group subject to intervention: individual cognitive stimulation program called "MD3"; Group 2 - group subject to usual care).The investigators intend to know the effect of the program on cognitive domains, quality of life and relationship between caregiver and care recipient. And, as well as understand the acceptability and applicability of the program by participants (dyad).
This study is intended to clarify the benefits to brain health and thinking processes that result from different forms of exercise. In particular, this study will investigate the possible benefits of physical exercise (such as pedaling an under-table stationary elliptical) or mental exercise (such as playing a videogame on a portable tablet), or combining these activities together (as in the iPACES™ exergame).
Cerebral accumulation of tau and beta-amyloid are major factors of Alzheimer's disease pathology. A novel Positron Emission Tomography (PET) tracer (18-F-AV-1451) now offers the ability to study tau protein deposition in vivo in subjects, in which information on cerebral amyloid deposition has already been gathered. This enables to study effects of tau deposition on neuronal integrity, their relation to effects of beta-amyloid deposition and how this contributes to cognitive impairment or well-being in the elderly.
