Improving memory in older adults with mild cognitive impairment

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the feasibility and effectiveness of remote, caregiver-led transcranial alternating current stimulation (tACS) for older adults experiencing memory decline. The study aims to determine if repeated tACS can lead to sustained improvements in neuronal activity and memory functions. Participants will undergo a comprehensive clinical assessment to confirm mild cognitive impairment and will be monitored for safety and efficacy throughout the intervention. The findings will inform future research on home-based tACS as a treatment option for memory decline.

Exclusion Criteria:

Mild Cognitive Impairment (MCI) patients

* age \< 55 years old
* any current diagnosis of a psychiatric disorder (e.g., schizophrenia, bipolar disorder, depressive disorder)
