Zapping the brain at 10 hz may help older adults stay steady
NCT ID NCT07097051
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Older adults with mild cognitive impairment often have weaker alpha brain waves, which are linked to problems with multitasking and balance. Researchers at High Point University are testing whether ten sessions of transcranial alternating current stimulation (tACS) can boost alpha activity and improve dual-task standing. Twenty participants aged 65 to 85 will be randomly assigned to receive either real tACS or a sham treatment, and researchers will measure changes in brain activity, posture, and executive function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial alternating current stimulation (tACS), a non-invasive brain stimulation technique
- What this could lead to
- If it works, tailored brain stimulation could become a non-drug way to help older adults with mild cognitive impairment stay steady on their feet and think more clearly.
- What could go wrong
- This is a small pilot study of 20 people, so any benefits may not hold up in larger trials. The sham-controlled design means some participants receive a placebo, and the long-term effects of repeated stimulation are not fully known.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 65+ * Who have been diagnosed with cognitive impairment (based in MoCA or TICS and Clinical Dementia Rating: CDR 0.5) * Ability to stand and walk independently * Willing and capable to give informed consent for the participation in the study after it has been thoroughly explained * Cut off of MOCA score \>18 will be applied * Able and willing to comply with all study requirements informed consent form was signed * Understanding of the ICF will be assessed by asking the participant to answer the following three questions: 1) What is the purpose of this study? 2) What are the risks of study involvement? 3) If you decide to participate, are you allowed to withdraw from the study at any time? Answers will be recorded by study personnel on the "Assessment of Protocol Understanding" form (see attached). Insufficient understanding will be defined by one or more incorrect answers, as determined at the discretion of the investigator. Exclusion Criteria: * Cut off of MOCA score \<18 will be applied * Major psychiatric co-morbidity including major depressive disorder, schizophrenia or psychosis * Blindness or other disabilities that prevent task performance * Self-reported history of stroke or neurodegenerative disorders other than MCI. * Self-reported active cancer for which chemo-/radiation therapy is being received. * Contraindications to tACS, as recorded on a standardized screening questionnaire, which include a reported seizure within the past two years, use of neuro-active drugs, self-reported presence of specific implanted medical devices (e.g., deep brain stimulator, medication infusion pump, cochlear implant, pacemaker, etc.), or the presence of any active dermatological condition, such as eczema, on the scalp.
