Parkinson's disease (PD) is a progressive neurological disease that has effects on both movement and mental health. One of the most common mental health complications of PD is depression. Up to 30% of Parkinson's patients will experience depression at some point.

The purpose of this study is to assess the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS), a non-invasive (does not enter the body) technique in improving depressive symptoms.

The purpose of this trial is to identify biomarkers of response to repetitive transcranial magnetic stimulation (rTMS) in individuals with first episode or treatment resistant depression.

This study aims to assess whether initial neuropsychological functioning and early changes in emotional processing in depressed adults correlates with symptom response to medications.

The perception of music requires coordinated neural activities in distributed multi-functional centers across both hemispheres. The association between musical abilities and other general cognitive functions have been studied in several populations with inconsistent results.

This is a randomized, double-blind, placebo-controlled, multicentre, parallel-group study to assess the cognitive effects of lurasidone in bipolar I and II patients (manic depression) who are in remission from an episode.

This study investigates the use of eye tracking technology as a diagnostic tool for mild traumatic brain injury (mTBI) and concussion. We are looking at the effect of additional working memory (short-term memory) load on the smoothness of eye movements in both concussed and healthy populations.

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.

This trial evaluates two standard of care treatments for opioid addiction: methadone and buprenorphine/naloxone.  The goal of this study is to determine the efficacy and safety of buprenorphine/naloxone as an alternative treatment for prescription opioid disorder.

Significant changes in brain morphology are observed in people with first-episode psychosis. Studies have shown that total brain volume and particular brain structures are decreased in people with psychosis disorders.
