Could a zapping cap boost memory after a head injury?
NCT ID NCT04504630
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a device that delivers a very mild electrical current to the scalp could improve memory in 26 older adults with mild cognitive impairment and a past traumatic brain injury. Participants received ten sessions of either real or fake stimulation to a brain region linked to memory. The researchers measured memory performance right after treatment and again three months later.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- High-definition transcranial direct current stimulation (HD-tDCS) device
- What this could lead to
- If it works, this could point toward a non-drug way to boost memory in people with mild cognitive impairment after a head injury.
- What could go wrong
- This was a very small, early study with only 26 participants. The results may not apply to everyone, and any memory improvements might be short-lived.
