Filter by:The goal of this study is to test the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a treatment for Mild Cognitive Impairment (MCI). Participants will be randomly assigned to one of three treatment groups: Group 1: Active Dorsolateral Prefrontal Cortex (DLPFC) rTMS; Group 2: Active Lateral Parietal Cortex (LPC) rTMS; and Group 3: Inactive rTMS (Placebo) control (evenly split between each coil location). Participation in the study takes approximately 7 ½ months-including a 2-to 4-week treatment phase (20 rTMS sessions) and a 6-month follow-up phase.
This is a proof of concept study to determine if changes in brain amyloid levels are evident three months after infusion of 0.4 g/kg of IVIG every 14 days x 5 infusions. Amyloid levels will be measured by Florbetapir PET and retinal scan.
The study explores whether selective memory complaints (SMC), mild cognitive impairment (MCI) and the comorbidity of Metabolic Syndrome symptomatic of peripheral and cerebral hypo-metabolism with corresponding epigenetic shifts in global DNA (deoxyribonucleic acid) methylation (away from nutrient availability and toward biosynthesis) are initiated by chronic metabolic inflexibility, over-activation of the mTOR (mammalian target of rapamycin) pathway, and the deregulation of neural oxidative phosphorylation.
Computerized cognitive interventions (CCIs) have been increasingly widely implemented among older adults with mild cognitive impairment (MCI). However, the efficacy of CCIs in maintaining or improving older adults' cognitive and functional health has been modest and highly variable. Older individuals' attitudes toward technology use may help explain some of the variability in CCI effects. The goal of this R21 is to generate proof-of-concept for an intervention that may improve attitudes toward computers among those with MCI, in turn improving engagement with and efficacy of a subsequent CCI. Person-centered care—that is, integrating individuals' preferences throughout the process of intervention--has improved intervention engagement among older persons, including those with MCI. A recent intervention predicated on this person-centered approach is called "personalized engagement program" (PEP). PEP involves a database of individualized computer-led leisure activities. The investigators' recent pilot data in senior living facilities suggest that PEP promotes psychological well-being among older persons with MCI, and may shift computers from dauntingly complex or personally irrelevant devices to familiar, enjoyable technology. These results are consistent with a number of theories indicating that exposure to pleasurable experiences with an object or task improves several dimensions of attitudes, including affective and cognitive components, as well as behavior and motivation. Grounded in both this pilot data and the theory around it, the investigators seek to take the next step in an arc of research ultimately intended to improve the efficacy of CCIs. A small randomized controlled trial (RCT) is proposed to assess whether an initial period of PEP, followed by a standard CCI, improves a) attitudes toward computers, b) engagement with the CCI, and c) cognitive outcomes, compared to an attention control period followed by CCI. Our design involving stratified random assignment of 50 assisted living residents with MCI from 4 senior living facilities to these two groups. The initial phase involves 4 weeks of either attention control or PEP, a "dose" suggested by prior work on attitude change and computers, followed by 6 weeks of CCI for both groups (a period our prior work indicates is sufficient for change in key cognitive domains among this population). This application is the first of which we are aware striving to augment CCIs, which are now ubiquitous, by addressing an attitudinal or affective element of the person, which are often ignored in the cognitive intervention literature. The adjuvant of PEP also answers increasing calls for "personalized" or "person-centered" behavioral interventions with older persons.
The research program explores how aging influences brain function in test-persons from a Danish birth cohort of men born in 1953.
Evidence suggests that a Mediterranean diet can have a beneficial effect on brain health. Mild cognitive impairment (MCI) describes problems with brain function such as difficulty with day-to-day memory and concentration. It is at this stage that Mediterranean diet could prove beneficial in terms of prevention. Previous research by Queens University investigated the opinions of patients with MCI and their care givers to inform the development of Mediterranean diet education material to encourage behaviour change. The study suggested that MCI patients lacked awareness of the link between Mediterranean diet and brain function, although were interested to learn more. Feedback on the developed educational material was positive although there were suggested improvements such as tailoring information to memory loss, a potential staged approach to delivery and adaptations to the material content. This present study aims to pilot test refined educational material among MCI participants to evaluate the feasibility of encouraging dietary behaviour change among this patient group.
Parkinson's disease (PD) affects more than 100,000 Canadians and results in symptoms affecting both motor and cognitive (thinking and memory) functions. Parkinson's disease with Mild Cognitive Impairment (MCI) frequently results in development of dementia for which few treatment options exist. Transcranial Magnetic Stimulation (TMS) is used to alter activity in the outer regions of the brain and has been shown in previous studies to increase cognitive performance in patients with different disorders. This study will investigate the effectiveness of TMS as a clinical treatment for the cognitive deficits associated with Parkinson's disease. 64 male and female participants between the ages of 50 and 90 will attend eight study visits over a period of 63 to 66 days. This study is a double-blind randomized clinical trial meaning the participant will be assigned by chance to either the TMS-treatment group or the Sham-treatment group. Additionally, a combination of memory and thinking tests and Magnetic Resonance Imaging (MRI) will be used to see if there are structural and functional changes within the brain. Genotyping and blood analysis before and after treatment for different biomarkers will also be performed and these data will be compared to the TMS data. Initially, this research will increase knowledge about the effects of TMS on various brain regions. Ultimately, we will be able to determine if TMS can be used as a complementary therapy for PD to improve cognitive performance and to reduce progression into dementia.
This non-pharmacological interventional feasibility study evaluate a computerized cognitive stimulation program in elderly with mild cognitive impairment.
This is a non-pharmacological study evaluating the differential effects of a computerized cognitive stimulation program according to the existence or not of white matter hyperintensities in elderly with mild cognitive impairment.
This study aims at investigating the effects of tablet-based puzzle video games on cognitive function and emotional well-being. This study extends preliminary findings of studies looking at short-term benefits of playing puzzle video games to a long-term intervention in healthy older adults and patients suffering from cognitive impairment due to mild cognitive impairment or acquired brain injury. To this end, the investigators compare two interventions: A tablet-based puzzle video games experimental intervention and a control intervention tablet newspaper-reading control intervention. This study uses a 16-week, assessor blinded, randomized crossover design with two phases of treatment and three waves of measurement. Participants are randomly allocated to either the experimental or control intervention for 8 weeks, then interventions are crossed over. Both groups receive both interventions in opposite order. At three time points (pre-, mid- and post-test) higher cognitive function and emotional well-being are tested using standardised neuropsychological tests and questionnaires.
