Expected Results: The investigators expect that 2-months of daily electromagnetic (RF) treatment will not present any significant side effects or safety issues. The investigators further expect that cognitive measures will be stable and/or improve by the end of treatment. In addition, the investigators anticipate that brain functional connectivity may be improved and that enhanced brain metabolism (FDG-PET) will occur. Changes in blood/CSF levels of various beta-amyloid and tau species are also anticipated.
