POTS brain fog targeted in new drug study
NCT ID NCT01988883
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tests whether a single dose of modafinil, a drug that promotes wakefulness, can improve concentration and mental clarity in people with Postural Tachycardia Syndrome (POTS). About 20 adults diagnosed with POTS will take the drug and then complete computer-based tests of attention and thinking. The goal is to better understand the 'brain fog' common in POTS and explore potential treatment options.
