The purpose of this study is to validate the English version of a new cognitive screening tool, the "Dépistage Cognitif de Québec" (DCQ).  The DCQ is a valid instrument that can be administered in less than 45 minutes and unlike other screening tools for dementia, it can provide more detailed information about memory and thinking skills.

We would like to explore different aspects of sexual identity among individuals who self-identify as asexual, bisexual, gay or heterosexual.

Recent evidence suggests a connection between the gut and the brain, and that certain conditions in the gut might be associated with neurological diseases. Research suggests that people with Alzheimer's Disease differ from healthy controls with respect to the bacteria (microbiome) present in their gut, however further research is needed. This project aims to study whether changes in the microbiome of the gut or oral cavity can be correlated to markers and clinical measures of Alzheimer's Disease.

The goal of the current study is to determine the prevalence, rate, and types of pregnancy complications and early life events that may be associated with the emergence of psychosis and related metabolic disorder in patients with schizophrenia spectrum disorders.

The Wellness Monitoring for Major Depressive Disorder (MDD) study is a prospective, longitudinal, observational study aimed at identifying biomarkers of relapse in MDD. Results may help refine clinical approach to relapse management, and may ultimately help MDD patients sustain wellness while on antidepressant medication.

The purpose of this study is to investigate the association between Parkinson's disease and the bacteria and fungi living in the gut and nose over a five-year period.

tDCS (transcranial Direct Current Stimulation) is a brain stimulation technique that involves passing a very low current through the scalp to change the excitability of underlying brain regions. Moreover, yoga and meditation have recently gained popularity for their proposed health benefits. This study seeks to investigate whether there is a combined effect of yoga, meditation, and tDCS on cognition.

This trial will compare a novel form of rTMS, intermittent Theta Burst Stimulation to the standard conventional high frequency left sided stimulation protocol. The Left dorsolateral prefrontal cortex will be the site of stimulation in both treatment conditions. The site of stimulation will be targeted using MRI co-registration.

To examine the effects of Parkinson's medication on decision making and risk taking in Parkinson's patients and healthy controls. 

The purpose of this study is evaluate the safety and efficacy of a new vaccine to protect children against bacteria that can lead to pneumococcal disease. 

The purpose of this study is to determine the lung and immune function benefits of stopping vaping for 72 hours in young adults who use e-cigarettes containing nicotine. The study also aims to determine if telling participants of their own personalized changes to their lung and immune function following the 72 hour abstinence period affects their motivation in quitting vaping.

The purpose of this study is to assess the effects of the COVID-19 outbreak and related quarantine measures on the physical and mental well-being of  health care workers, as well as the general population.

The purpose of this study is to explore brain energetics using Bold fMRI and FDG PET scanning in healthy controls.  We will complete fMRI and FDG PET scanss on 30 healthy volunteers, obtaining a set of healthy control data using the recently acquired Signa Hybrid Positron Emission Tomography/3T Magnetic Resonance Imaging scanner located in the multi-modal imaging suite at the Djavad Mowafaghian Centre for Brain Health.  These data will be used as reference to investigate several brain alterations induced by disease.  This approach allows for the best analysis of data and accounts for scanne

The purpose of this study is to develop a monitoring tool that can measure body movement, mood, and disease symptoms from video recordings in the home setting.

The purpose of this study is to examine the safety of running for knee joint health through an assessment of running biomechanics and MRI-derived measures of cartilage composition. 

The purpose of this study is to explore sequences for functional magnetic resonance imaging (MRI) under a variety of conditions, using various stimuli to obtain healthy control data for comparison with other patient populations with brain diseases such as Alzheimer's and Parkinson's.

Research has shown that Alzheimer’s disease can cause changes in a person’s speech and eye-movements. As neurodegeneration progresses, gaze and language pathways are disrupted. This study compares the speech and eye-movements of people with Alzheimer’s disease and mild cognitive impairment (MCI) to healthy volunteers, to see if there are patterns that can be used to detect Alzheimer’s disease early, and to monitor the progression of Alzheimer’s disease over time.
