Sleep troubles linked to suicide attempts? study investigates
NCT ID NCT03793699
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether sleep disorders like insomnia and nightmares are connected to suicide attempts. Researchers compared people who had just attempted suicide with those who had suicidal thoughts but no attempt. The goal was to see if sleep problems might be a trigger. The study was stopped early and included only 24 people, so results are limited.
What this could mean

- What this could lead to
- If successful, this could clarify whether sleep problems are a trigger for suicide attempts, helping to identify at-risk individuals earlier.
- What could go wrong
- The study was terminated early with only 24 participants, so results may be too limited to draw firm conclusions. It is an observational study, not testing a treatment.
