Can brain zaps and hearing aids boost memory in seniors?
NCT ID NCT07389213
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether combining a non-invasive brain stimulation technique called rTMS with hearing aids can improve cognitive function in older adults with age-related hearing loss. About 189 participants, including those with and without hearing aids, will receive two 14-day courses of rTMS and be tested on memory, thinking, and brain activity. The goal is to see if this combination can help slow or reverse cognitive decline.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- repetitive Transcranial Magnetic Stimulation (rTMS) device
- What this could lead to
- If it works, this could point toward a non-drug way to slow or improve cognitive decline in older adults with hearing loss.
- What could go wrong
- This is an early real-world study, not a large randomized trial. Results may not apply to everyone, and the cognitive benefits of rTMS are still uncertain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age ≥50 years and ≤85 years, regardless of gender. 2. Diagnosed with age-related hearing loss (ARHL), characterized by symmetrical, slowly progressing hearing loss primarily affecting high frequencies, along with decreased speech recognition ability due to aging. This is in accordance with the "Expert Consensus on Diagnosis and Intervention of Age-Related Hearing Loss" 2019 edition.(Only ARHL-nonHA group and ARHL-HA group) 3. The better ear has moderate, moderately severe, or severe hearing loss (based on the 2021 WHO hearing classification standards, i.e., PTA between 35~79dB). 4. Wearing hearing aids for more than half a year, with daily wearing time exceeding 7.2 hours; (Only ARHL-HA group) 5. Chinese nationals who can complete all assessments in Chinese. 6. Right-handed. 7. Educational level of at least 6 years. 8. Informed consent obtained, agreeing to participate in the trial with no plans to relocate within one year. Exclusion Criteria: 1. Exclusion of hearing loss due to noise, genetics, ototoxic drugs, or other non-age-related causes; 2. History of central nervous system disorders such as cerebral infarction, stroke, epilepsy, or traumatic brain injury; 3. Diagnosis of dementia or other neurodegenerative diseases that affect compliance with the study; 4. Presence of major neurological disorders, severe systemic diseases, family history of hereditary conditions, or major psychiatric disorders; 5. Contraindications to MRI; 6. Contraindications to rTMS.
