Summary

This study tested whether two types of mild electrical brain stimulation (tDCS and tRNS) could improve memory and thinking in 36 people with schizophrenia. Participants received both types of stimulation on different days to compare effects. The goal was to see if these safe, non-invasive techniques could help with cognitive problems that often come with schizophrenia.

What this could mean

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

Active substance: transcranial direct current stimulation (tDCS) and transcranial random noise stimulation (tRNS) devices
What this could lead to: If it works, this could point toward a non-drug way to help people with schizophrenia think more clearly and remember better.
What could go wrong: This is a small, early-stage study with only 36 participants. The effects may be small or not last long, and results may not apply to everyone with schizophrenia.
