Scientists probe why POTS patients feel foggy
NCT ID NCT04137757
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looks at why people with Postural Tachycardia Syndrome (POTS) often have trouble thinking clearly, known as 'brain fog.' Researchers will compare brain scans of 21 POTS patients and healthy volunteers while they do mental tasks, both sitting and under simulated standing stress. The goal is to see if brain regions work harder in POTS patients, especially when upright.
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 explain the cause of brain fog in POTS, pointing toward future treatments or management strategies.
- What could go wrong
- This is a small, early-stage observational study with only 21 participants. It is not testing a treatment, so it may not lead directly to any therapy.
