Inactive sham coil treatment
Key Inclusion and Exclusion criteria Inclusion:
Age 55–90, amnestic MCI, stable medications, Geriatric Depression Scale score less than 6; Ability to obtain a motor threshold; Study partner available; Visual and auditory acuity adequate for neuropsychological testing; Good general health with no diseases expected to interfere with the study.
Magnetic field safety concern such as a cardiac pacemaker, cochlear implant, metal fragments in the eyes, skin or body, or pregnancy; Any significant neurological disease other than suspected incipient Alzheimer’s disease; Unstable cardiac disease or recent myocardial infarction; Any significant systemic illness or unstable medical condition that could lead to difficulty with protocol adherence; History of epilepsy or repetitive seizure; History of a medical condition or current use/abuse of medications and substances that increase the risk of a seizure (e.g. recent traumatic brain injury, current use of stimulants), Known history of major depression or bipolar disorder within the past year; Current alcohol or substance abuse (not including caffeine or nicotine) within the past year.

Primary outcomes Change in memory, as measured by the California Verbal Learning Test-II (CVLT-II) Trials 1–5 Total raw score [Time Frame: Baseline, 1 week after completing the 20-session intervention]
Key Secondary outcomes Behavioral outcomes include:
Subscores of the CVLT-II, GDS, Everyday Cognition (ECog) Questionnaire, Montreal Cognitive Assessment (MoCA), tests of language, executive, and visuospatial function.
Neuroimaging outcomes include:
Change in functional connectivity metrics including comparison of DLPFC to LPC.
Other biomarker outcomes:
Change in brain-derived neurotropic factor (BDNF) plasma levels
