Filter by:The PrimeCog study aims to describe the symptomatology and pathophysiology of stress-induced exhaustion disorder (SED) and major depressive disorder (MDD) compared to healthy controls (HC). The participants will be recruited at primary care centers, and samples of blood, saliva, and hair will be collected. Digital questionnaires covering psychosocial variables and screening instruments for the detection of depression, anxiety, etc., along with a digital cognitive test battery, will be performed at home. Subsequently, an MRI of the brain will be performed, and analysis of biomarkers for stress, inflammation, and neurodegeneration will be conducted. These procedures will be repeated after twelve and twenty-four months. The study will investigate differences in the biomarkers, neuroimaging findings, and cognitive abilities between patients with SED, MDD, and controls over time. Associations between the symptom severity of MDD/SED and psychosocial variables, cognition, MRI, and the biomarkers will also be examined. The aim is to provide new diagnostic tools for differentiation between MDD and SED and guide individualized treatment based on underlying pathophysiology and cognitive function. All necessary competences for conducting this extensive study are represented within the research group. The PrimeCog study is unique in its comprehensive design, addressing knowledge gaps, and directly comparing these diagnoses over time in primary care, where patients are typically treated.
This clinical trial aims to investigate the effects of a 70-day consumption of cranberry juice on cognitive and motor accuracy, mental and physiological stress, and stress response in healthy men and women between the ages of 30 and 55 who engage in multitasking. The trial will utilize a randomized, double-blinded, placebo-controlled design. It is worth noting that studies have shown that over half of middle-aged Americans experience stress, which can lead to cognitive decline and depression. Previous clinical trials have indicated that consuming polyphenol-rich foods can have positive effects on cognitive function in humans. However, no study to date has examined the long-term effects of cranberry juice consumption on cognitive performance, mental stress, and stress response specifically in individuals engaged in multitasking. Based on this gap in knowledge, the investigators hypothesize the following: (1) chronic consumption of cranberry juice will improve cognitive and motor accuracy, as well as mental and psychological stress responses in young adults subjected to intense multitasking. (2) cranberry juice consumption will alleviate the negative consequences of frequent intense multitasking, such as fatigue, mood fluctuations, cognitive impairment, and memory issues. Additionally, it is expected to have a positive impact on stress biomarkers and neurotransmitter levels. By conducting this clinical trial, the investigators aim to shed light on the potential benefits of cranberry juice consumption in improving cognitive performance, mitigating mental stress, and positively influencing stress responses in individuals who engage in intense multitasking.
Preventing food allergic reactions predominantly relies on allergen avoidance and managing this daily causes high anxiety in some patients, while having an allergic reaction can cause a post-traumatic stress disorder-like syndrome in children. The underlying mechanisms of these psychological changes are poorly understood, but one potential mechanism may be post-natal hippocampal neurogenesis (HN). HN is the production of new neurons from stem cells in the hippocampus which is one of the brain centres for memory and mood regulation. HN has been associated with cognitive function and some psychiatric disorders. Importantly, it can be influenced by both internal (bloodstream) and external (exercise, diet, etc.) factors. This study will explore the link between food allergy and children's mental health and cognition, and to determine whether this is linked to changes in HN.
This study will investigate whether transcranial direct current stimulation (tDCS) enhances the effects of cognitive training in older adults with depression.
This will be a 12-week randomized trial. Outpatients and patients from the Mood and Anxiety program at the Centre for Addiction and Mental Health (CAMH) with a current diagnosis of post-traumatic stressed disorder (PTSD) and cannabis-use disorder (CUD) will be randomized to receive individual motivational interviewing therapy and contingency management (n = 12) or individual motivational interviewing therapy alone (control group, n = 12) after enrolment.
Objectives: - First, to determine if patients with a history of AF have acute measurable changes in cognitive functioning while in an episode of AF. - Second, to collect basic insight into what specific physiologic (blood pressure, pulse oximetry, heart rate, temperature) and pharmacologic (antiarrhythmic medications, rate control medications, anticoagulants, antiplatelet medications, etc.) factors minimize the neurological impact on patients while they are in AF. It is hypothesized that when using a tablet-based cognitive testing software - Cambridge Cognition (specifically to assess executive function, learning and working memory: Rapid Visual Information Processing test, Spatial Working Memory/Spatial Span Task tests, One touch Stockings of Cambridge test, Cambridge Gambling Task, Multitasking Test/Intra-Extra Dimensional Set shift tests) - a significant difference will be noted between how the patients perform while in atrial fibrillation compared to the patients' performance while in normal sinus rhythm.
