Introduction
cognitive decline, aMCI
The adult aging population is rapidly growing as the Baby Boomer generation now totals over 71 million adults in the United States alone. This rise in the population of seniors is also associated with increased incidence of cognitive decline and dementiasAs individuals age, declines in cognitive control (working memory and attention) become noticeable and during progression to aMCI these deficits become detrimental to independent daily livingOne promising technique at enhancing benefits from CCT to improve cognitive function is noninvasive transcranial alternating current stimulation (tACS), which has demonstrated evidence in enhancing cognition in healthy individualsFrontal theta activity, and its corresponding cognitive control functions, decline in advanced ageIn the current study, we hypothesized that 5 days of theta tACS + CCT would yield larger improvements in cognitive control performance compared to control tACS + CCT, a pattern we observed in healthy older adults
