The second visit will start approximately 24-72 hours after the first visit. During visit 2 to visit 20, participants will receive about 1 hour of TMS session 5 days a week for 4 weeks. During the 21st visit, which will be approximately one day after the last TMS session, participants will be asked to repeat 1 hour of EEG before TMS; 0.5-hour of memory testing using MoCA and Trail Making Test (Trial A and B), 1 hour TMS and 1 hour of EEG after TMS. For this study, a questionnaire concerning any potential side effects will be administrated before and after each session.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '55 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Males and females,\n* Age 55-85 years old,\n* Able to consent and agrees to participate (if patient does not have capacity to give a consent then a caregiver will be asked )\n* Fluent in English\n* Diagnosed with probable AD (NINCDS-ADRDA criteria) mild stage as defined by a composite score of 1 or less on clinical dementia rating scale (CDR)\n\nExclusion Criteria:\n\n* Other neurological illness that would interfere with cognitive function (significant stroke, seizure d/o, Parkinson, Huntington etc.).\n* Psychiatric illness known to affect cognition such as schizophrenia/schizo-affective disorder, substance use disorder within 1 year of study, active depression or anxiety disorder or history of recurrent major mood disorder prior to cognitive change.\n* Medications: benzodiazepines will be exclusionary.
