NCT ID NCT06248268
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looks at how the brain works in people who have attempted suicide compared to those who have only thought about it. Researchers will use simple computer tasks to measure things like impulse control and attention. The goal is to find patterns that might help predict who is at higher risk of acting on suicidal thoughts.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help identify specific brain patterns that distinguish suicide attempters from ideators, potentially improving prevention strategies.
- What could go wrong
- This is an observational study, not a treatment trial. It only measures differences at one point in time, so it cannot prove cause and effect.

Who is studied
This quantitative cross-sectional study with four groups will be conducted at the University Hospital of Psychiatry and Psychotherapy, Bern. Patients with at least one suicide attempt in their past (SUAT), patients with suicidal ideation (SUID), patients from the same clinical cohort without neither suicidal behavior or ideation (CLIN), and the healthy group (HLTH). The cohorts to be examined (SUAT \& SUID) will be compared to two control groups (CLIN \& HLTH).
