Zapping the Brain's memory center: a new hope for mild cognitive decline?
NCT ID NCT07771036
First seen Aug 18, 2026 · Last updated Aug 19, 2026 · Updated 1 time
Summary
This trial tests whether a single 20-minute session of a noninvasive brain stimulation technique called temporal interference stimulation, aimed at the hippocampus, can improve memory and the ability to walk and balance while doing another task in older adults with mild cognitive impairment. Participants will receive both active and sham stimulation in random order, with memory tests, balance assessments, and brain scans before and after each session. The goal is to see if this approach can provide immediate benefits for cognitive and motor function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Temporal interference stimulation (TIS), a noninvasive brain stimulation technique targeting the hippocampus
- What this could lead to
- If effective, this could offer a noninvasive, drug-free way to temporarily improve memory and balance in older adults with mild cognitive impairment, potentially slowing functional decline.
- What could go wrong
- This is a small, early-stage trial with only 21 participants and a single session of stimulation, so any effects may be short-lived or not generalize. The procedure is generally considered safe, but individual responses can vary.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
1. Aged 65 years or older; 2. Presence of subjective memory complaints; 3. Objective cognitive impairment: screened using the Montreal Cognitive Assessment-Bejingversion (MoCA-BJ). The MoCA-BJ total score is 30 points. For individuals with \<12 years ofeducation, 1 point is added to the raw total score (corrected total score capped at 30 points); acorrected total score \<26 points indicates risk of cognitive impairment; 4. Clinical Dementia Rating (CDR) score of 0.5; 5. Does not meet diagnostic criteria for dementia: Mini-Mental State Examination (MMSE) scores\>18 for illiterate individuals, 221 for those with primary school education, and \>25 for those withjunior high school education or above;6. Retains independent activities of daily living (ADL) and is capable of cooperating with allassessments and interventions.
