Filter by:The purpose of this research study is to see how the brain changes in patients receiving chemotherapy (cytotoxic drug) treatment for colon or rectal cancer at Parkview Cancer Institute. This information will be used to identify helpful tests to diagnose individuals at risk for developing difficulties with thinking and memory due to their cancer treatments.
A study in Finland found that a multidomain intervention of physical activity, nutritional guidance, cognitive training, social activities and management of vascular risk factors slowed cognitive decline in healthy older adults at increased risk of cognitive decline. A 6-month pilot study was initiated in Singapore, which demonstrated the cultural feasibility and practicality of the FINGER interventions and a set of locally adapted interventions in an Asian population. The SINGER study is a 2-year randomized controlled trial that aims to test the efficacy and safety of these lifestyle changes, including diet and cardiovascular risk factor management, cognitive and physical exercises, in delaying cognitive decline in older adults at risk of dementia.
The Trial Assessing Light-Intensity Exercise on the Health of Older Breast Cancer Survivors pilot randomized controlled trial aims to evaluate the efficacy of a home-based, light-intensity physical activity intervention among 56 obese, older adult breast cancer survivors, in comparison to a usual care control condition.
The prevalence of major depressive disorder (MDD) is ~5.0%, and rates of co-occurring SUDs in these patients approach 40-50%. Specifically, rates of co-morbid cannabis use disorder (CUD) in patients with MDD are elevated 2-3 fold compared to 2.9% in the general population, and is associated with poorer treatment outcomes and impaired cognitive and psychosocial functioning in comparison to MDD patients without CUD. Most studies of cannabis use in MDD are cross-sectional in design, and therefore causal relationships are unclear. This study investigates the effects of cannabis abstinence over a 28-day period in patients with MDD with co-occurring CUD using a randomized controlled design, namely contingent reinforcement.
Cognitive difficulties can affect many people who live with multiple sclerosis (MS). These difficulties, such as within thinking, memory, and problem solving, can have an impact on important aspects of an individual's life, including their daily activities, work, and how they manage their condition. Previous studies have suggested that cognitive difficulties affect approximately 40-70% of people living with MS, yet there are currently no treatments to target these problems. Recent research has directed towards a non-invasive intervention which stimulates a part of the brain (called the dorsolateral prefrontal cortex, or DLPFC for short) which is reported to participate in cognitive processes, such as memory, thinking, and attention. This intervention, called "intermittent theta burst stimulation" (iTBS), involves placing a magnetic device to the skull to activate the DLPFC underneath. This technique has been used successfully in the treatment of depression and is widely considered safe and painless. Previous studies have also shown that iTBS intervention can lead to improvements in cognitive processes. Before the investigators can progress to a large trial to explore its clinical effectiveness for reducing cognitive problems for people with MS, some aspects regarding its feasibility need to be clarified, for example whether it is an acceptable and tolerable intervention for people living with MS. A single-centre, mixed methods feasibility randomised controlled trial will be conducted to compare four groups (10 participants each) of iTBS administration. At baseline, End of Intervention (EOI), and 8-week follow up, the investigators will complete outcome measures to evaluate cognition, mood and fatigue. Participants will also undergo MRI scans at baseline and EOI. Following participation, participants will be interviews and the investigators will organise a post-participation workshop to explore their experiences of the trial, including the tolerability of the protocol and acceptability of the visit schedule, and any differences in cognition.
This research aims at describing the relationship between white adipose tissue inflammation and post-operative cognitive dysfunctions.The possible link between inflammatory cytokines secretions of the white adipose tissue of a surgical wound and the arising of patient's cognitive dysfunction in the post-operative course will be investigated. The hypothesis is that obese patient's inflammation of the white adipose tissue leads to cognitive dysfunction.
The purpose of this study is to determine whether a non-invasive brain stimulation technique, transcranial direct current stimulation (tDCS), combined with traditional cognitive therapy will improve cognitive function in patients with subacute stroke.
The prevalence of neurodegenerative diseases is expected to increase over the next years, in parallel with the aging of the world population. Therefore, it is important to identify new methods to prevent, delay or stop the neurodegenerative waterfall responsible for dementia conversion. To date, there is no fully proven pharmacological treatment for cognitive impairment and the available pharmacological treatments have limited efficacy because consist in symptomatic drugs with adverse side effects. On this point, non-pharmacological intervention may represent adjunctive therapy to medications in order to prevent or delay the onset of the cognitive deficits or dementia. Recently we evaluated the effectiveness of a computerized cognitive training (CoRe) in patients with early cognitive impairment. The main goal of the present protocol is to evaluate the efficacy of the home-based version of CoRe (Home CoRe). To this end, mild dementia or early cognitive impairment, and persons with Subjective Cognitive Impairment (SCI) are enrolled and randomly assigned to the experimental group (Home CoRe) or control group (CoRe). All patients are evaluated before (T0) and after (T1) treatment with an exhaustive neuropsychological assessment. Furthermore, follow-up visits are scheduled 6 months (T2) and 12 months (T3) after the end of the treatment.
The COgnitive and Physical Exercise to improve Outcomes after Surgery (COPE-iOS) study is testing the hypothesis that a pragmatic program combining computerized cognitive training and physical training throughout the perioperative period will improve long-term cognitive and disability outcomes in older surgical patients at high risk for decline. To accomplish these goals, the Investigators are randomizing 250 patients ≥60 years old undergoing elective major non-cardiac surgery with expected hospitalization ≥3 days to a pragmatic comprehensive training program (computerized cognitive training and supervised progressive physical exercise) or to active control (control computer game, stretching exercises) for 2-4 weeks prior to surgery and for 3 months after discharge. At baseline and after discharge, the Investigators will assess global cognition, activities of daily living, depression, endothelial and blood brain barrier function (blood biomarkers), and neuroimaging (anatomical and functional MRI). In this early stage trial, the Investigators will determine if certain subgroups benefit most, program aspects with greatest effect on outcomes, mechanistic associations with outcomes, and additional exploratory analyses.
Patients with cancer often suffer from a symptom cluster, including pain, fatigue, sleep difficulties, emotional distress and cognitive impairments. In oncology settings, there is a growing interest in "mind-body" intervention, to relieve them in a non-pharmacological way. Hypnosis and meditation are two modified state of consciousness shown to positively this symptom cluster. Cognitive trance is also a modified state of consciousness, but is induced by body movements and/or vocalizations. Subjective reports of experts in cognitive trance showed a modification of self, emotion regulation, pain perception, attention and concentration. However, we still need to develop studies to better characterise this particular state of consciousness and its clinical applications. Our randomized-controlled trial aims at comparing both interventions in terms of (1) benefits on cancer patients' quality of life (pain, fatigue, sleep, distress, cognitive impairments), (2) phenomenological/subjective experiences and neurophysiological correlates, and (3) mechanisms involved in patients' responsiveness, based on the biopsychosocial model of hypnosis.
