The goal of this pilot study is to determine whether a high-dose form of non-invasive brain stimulation is a promising and safe treatment for Mild Cognitive Impairment. Transcranial magnetic stimulation (TMS) is an FDA approved treatment for depression. In studies of TMS for depression and other disorders, individuals have experienced improved cognitive function. Thus, the current study is testing whether TMS is safe, feasible and effective in improving cognition in individuals with Mild Cognitive Impairment.
