Who could benefit from this research

Could help

Adults with major depressive disorder who have a history of suicide attempts, adults with depression without such history, and healthy volunteers.

Less likely to help

Healthy volunteers may participate for comparison but are not the target for therapeutic benefit.

What this research studies

This project follows 100 adults with major depression who have a higher risk of suicide due to past attempts, plus 50 with depression but no prior attempts and 50 healthy volunteers. It uses real-time self-reports several times a day for a week to capture how daily stress influences thoughts of suicide and negative moods, along with biological and cognitive measures. The study will look at modifiable factors like gut microbiome, inflammation, attention and memory, and psychological pain to see what might moderate the stress response. Ketamine's potential to influence these factors will be explored to identify targets for preventing suicidal thoughts and behaviors in the future.

Why it matters

Potential benefit: If successful, findings could lead to new strategies to prevent suicidal thoughts and improve emotional resilience in people with depression.

How similar studies have gone: Previous research suggests stress can trigger suicidal thoughts in susceptible individuals, with ketamine showing potential rapid effects on mood and pain processing in some studies.
