Gentle brain zaps may help stroke survivors regain spatial awareness
NCT ID NCT04458974
First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This study investigates whether a noninvasive brain stimulation technique called transcranial direct current stimulation (tDCS) can enhance recovery from spatial neglect — a condition where stroke survivors ignore one side of their world. Participants who had a stroke 3 to 12 months ago will receive either real or sham tDCS alongside standard rehabilitation for two weeks. The goal is to see if the brain stimulation reduces neglect symptoms and improves daily functioning.
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) using a multisite device
- What this could lead to
- If successful, this approach could offer a safe, noninvasive way to boost recovery from spatial neglect after stroke, improving independence and quality of life.
- What could go wrong
- This is a small, early-stage trial with only 30 participants, so results may not apply broadly. The treatment effect may be modest or no better than sham stimulation.
