Brain zaps at personal brain rhythms may sharpen memory in schizophrenia
NCT ID NCT07701343
First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time
Summary
This study tests whether a gentle, non-invasive brain stimulation technique called transcranial alternating current stimulation (tACS) can improve working memory in people with schizophrenia. Thirty participants receive both real and sham stimulation in separate sessions while performing a memory task. The stimulation is personalized to each person's natural brain rhythm and targets areas involved in memory.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- transcranial alternating current stimulation (tACS) — a non-invasive brain stimulation device delivering weak electrical currents at individual alpha frequency to the scalp during a working memory task
- What this could lead to
- If effective, this approach could offer a non-drug, brain-stimulation method to improve working memory in schizophrenia, potentially enhancing daily functioning.
- What could go wrong
- This is a small, early-stage trial with only 30 participants and single sessions, so results may not generalize or show lasting benefit. The effect may be subtle or absent.
