The purpose of this study is to evaluate the feasibility of using repetitive transcranial magnetic stimulation (rTMS) to treat depression.
The purpose of this study is to test the feasibility of Magnetic Seizure Therapy for treating depression in patients diagnosed with Parkinson's Disease.
The purpose of this study is to learn about biomarkers (biological features such as proteins, genes, and brain images that indicate the state of a disease in a person), and how they can help predict treatment outcomes in patients with clinical depression.
Developing a risk assessment tool for discriminating social cognition deficits in dementia from that of depression
To look at the differences in "social cognition"- the ability to look at the interpret the social world and put yourself in someone else's shoes - between people with depression, people with frontotemporal dementia and healthy controls.
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. We aim to investigate whether transcranial direct current stimulation (tDCS), a type of electrical stimulation for the brain, can improve depression in PD as well as improve motor function in PD.
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.
Closed for Recruitment
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.
Repetitive transcranial magnetic stimulation (rTMS) is an emerging treatment for medically refractory major depressive disorder (MDD). rTMS involves direct stimulation of cortical neurons using externally applied, powerful, focused magnetic field pulses. Dozens of studies and several meta-analyses over the last 15 years have shown that rTMS of the dorsolateral prefrontal cortex (DLPFC) produces statistically significant improvements in MDD, even when medications have failed. However, other possible targets may also yield improvement in symptoms.
This study is a pilot to assess feasibility of the protocol in patients and controls across six participating sites. The goal is to identify biological markers (biomarkers)that can be measured at baseline or early in treatment to predict treatment outcome in individual patients with Major Depressive Disorder (MDD). Biomarkers of interest will be clinical (using interview and self-report measures), molecular (from blood samples) and neurobiological (using neuroimaging and EEG).
