This intervention will utilize 8 electrodes; electrode placement and current parameters for each electrode have been optimized using a standard brain to generate an average electric field of 0.25 V\u002Fm. To ensure adherence to current safety recommendations for tACS, optimizations will be constrained to a maximum of total injected current 4.0 mA and a max. current per electrode of 2.0 mA.

Those with lower alpha activity, especially in the front part of the brain, usually have problems with executive functions like planning and multitasking. Our research has shown that older adults with lower alpha power in these areas also struggle more with balance when they have to do two things at once (like standing and performing a cognitive task simultaneously).\n\nThe investigators believe that increasing alpha power in older adults with MCI could improve their balance and executive function, helping them stay independent longer. In early studies, the investigators found that using transcranial alternating current stimulation (tACS) at 10 Hz on the front part of the brain can boost alpha power and balance immediately after a single session in older adults with MCI. The effect was stronger in those whose natural brain activity was close to the 10 Hz stimulation.\n\nBased on these findings, the investigators plan to conduct a pilot study with older adults aged 65-85 years with MCI. Participants will be randomly assigned to receive either real tACS or a sham (placebo) treatment. Our main hypothesis is that real tACS will improve balance when multitasking, and these improvements will last for 1 to 3 months after the treatment. The investigators also believe that tACS will enhance other aspects of executive function and mobility and that these improvements will be linked to increased alpha activity in the brain.\n\nThrough this study, we aim to gather strong evidence that tailored tACS is a promising treatment to improve cognitive and motor functions and overall brain activity in older adults with MCI.",[75],"Mild Cognitive Impairment (MCI)",[77,78,79,80],"brain stimulation","balance","cognition","executive function","2025-07-30",{"date":83,"type":84},"2025-07-31","ACTUAL",{"date":86,"type":84},"2025-05-13",{"date":88,"type":69},"2026-12-31",{"name":5,"class":6},1]
