Brain scans reveal why some people handle stress better
NCT ID NCT06243783
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how acute stress affects the brain's energy metabolism and connectivity. Sixty-eight healthy volunteers will undergo brain scans while performing math tasks designed to induce stress. The goal is to understand individual differences in stress responses, which could help explain why some people are more vulnerable to stress-related mental disorders.
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 research could help explain why some people handle stress better than others, potentially guiding future treatments for stress-related mental disorders.
- What could go wrong
- This is an early observational study with only 68 healthy participants, so results may not apply to everyone. It measures brain activity, not a treatment, so direct benefits are limited.
