Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether a mild electrical current applied to the scalp (tDCS) before computer-based cognitive training can improve thinking skills like memory and attention in people with schizophrenia. 120 adults aged 18-65 will receive either real or fake tDCS for 20 minutes, followed by 30 minutes of brain games, over 15 sessions in three weeks. Researchers will compare test scores and brain activity at the start, right after treatment, and 8 weeks later to see if the effects last.

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)
What this could lead to
If it works, this could point toward a way to boost cognitive rehabilitation for people with schizophrenia, potentially improving memory, attention, and planning.
What could go wrong
This is an early-stage study with 120 people, so results may not apply to everyone. The improvement might be small or not last long, and tDCS can cause mild side effects like tingling or headache.
