Summary

This study tested a 12-week smartphone program called SuperCAP for people with post-COVID syndrome. The program includes daily games, exercises, and videos to improve thinking, mood, and daily function. Sixty adults with ongoing cognitive complaints took part, and researchers measured changes in self-reported thinking abilities and depression symptoms.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: SuperCAP Program (a supervised computerized active program delivered via cell phone)
What this could lead to: If it works, this could offer a practical, home-based way to ease brain fog and emotional struggles after COVID-19.
What could go wrong: This is a small, completed study with only 60 participants and no control group, so results may not be widely applicable. The program requires daily effort and a positive attitude toward technology.
