Filter by: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 proposed research will test a novel network-based neurostimulation approach using MRI-derived measures of brain connectivity to establish target sites for neurostimulation and test for the enhancement of memory function beyond a sham stimulation condition. This will be tested in cohort of MCI adults using network-based transcranial magnetic stimulation (TMS) to assess for behavioral improvement due to the controlled intervention. This study will provide important evidence towards the efficacy of neuromodulatory treatments for memory decline and will accelerate the discovery of potent non-invasive treatments to remediate cognitive decline in cognitively impaired older adults.
Cognitive decline represents a major threat among the deleterious effects of population aging. The investigators propose to conduct an RCT (randomized controlled trial) on the subpopulation of MCI patients, and examine whether intensive musical or psychomotor group interventions can improve their cognitive and sensorimotor functioning, as well as induce brain plasticity, compared to a passive healthy control group, matched for age, gender and education level. The 2 training regimens will take place twice a week over 6 months and will be provided by professionals in each field.
Post-stroke cognitive impairment is common in stroke survivors. Cognitive function is related to walking ability. The dual task walking is required for daily activities, however, such ability is even more challenging than single walking for people with stroke. The purpose of present study is to investigate the effects of combining cognitive and treadmill training on cognitive function and dual task walking performance in chronic stroke patients with cognitive impairment.

This clinical study will use the small molecule translocator protein (TSPO) ligand, 18F-labeled DPA- 714, to visualize and quantify neuroinflammation in treatment naivete women with stage 1-4 newly diagnosed ovarian cancer (without brain metastases) prior to starting neoadjuvant chemotherapy treatment (baseline) and within a month of completing first 6 cycles of cytotoxic chemotherapy treatment (follow-up). In addition, we will use the well-characterized small molecule PET(Positron Emission Tomography) tracer, 11C-labeled Pittsburgh compound B (PiB) to visualize and quantify the regional brain distribution of pathological amyloid deposition at baseline only. The brain amyloid PET and MRI data acquired through this study will be correlated with cognitive test data, clinical data, genetic testing, and biospecimens collected in this study.
The purpose of this study is to determine the effect of desflurane on postoperative cognitive dysfunction
Mild Cognitive Impairment, Alzheimer's Disease and Parkinson's Disease all represent a range of degenerative conditions that have cognitive impairments which all limit the ability for older individuals to self-manage care, participate in daily activities and community participation. The consequences of these progressive diseases increase the requirement for residential care, associated medical costs and may negatively impact the overall quality of life and mental health for individuals. According to the Alzheimer Society of Canada, over the next few decades, more than 1 million Canadian's will be living with decreased cognitive ability and will require an increased amount of support, whether through family or institutional sources. Currently, there are few cognitive programs for individuals diagnosed with mild cognitive impairment or for individuals wishing to maintain their current level of cognitive ability which translates to meaningful improvements in daily living and independence, as well as generalized intelligence. To date, the Watson Centre Society for Brain Health (WCSBH) has successfully improved cognitive capacity, executive function and quality of life for over 100 individuals following a wide range of brain injury, and currently has a 77% return to work rate following completion of the full program. The program includes a combination of physical exercise, cognitive training and mindfulness meditation. The purpose of the research study is to explore the impact of an interdisciplinary cognitive rehabilitation program has upon the cognitive functioning and quality of life for individuals who are assessed to have mild cognitive impairment (MCI). In particular, the aims of this study include: 1) To evaluate changes in cognition and quality life in older adults with MCI. 2) To explore the potential for intensive cognitive intervention in slowing cognitive degeneration in older adults with MCI.
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.
