Summary
This trial is studying what happens in the brain when people have thought about or attempted suicide. It will help researchers develop better treatments for suicidal people.
Who is the study for?
This trial is for adults aged 18-70 who have recently considered or attempted suicide, those with past suicidal thoughts or attempts, individuals with depression or anxiety but no suicidal ideation, and healthy volunteers. Participants must understand the study well enough to consent and agree to use effective birth control if they can get pregnant.
What is being tested?
The study aims to understand brain activity related to suicide through interviews, tests, MRI scans using different strength scanners (3T and 7T), sleep studies, blood tests, and optional tasks like a lumbar puncture. Some participants may receive ketamine infusions in later phases of the trial.
What are the potential side effects?
Possible side effects include discomfort from MRI scans for those with claustrophobia or metal implants. Ketamine can cause dissociation, dizziness, nausea, increased heart rate and blood pressure changes. The extent of side effects will vary among individuals.
