• For the randomized stage only-has a history of prior TMS treatment (not TMS naïve)
• Alteration in cognitive-enhancement medication (or other treatment) dose within the past 2 months or active plans for dose alteration during the course of the study (previously unplanned changes that occur during the study will be examined on a case-by-case basis)
• Has started treatment with lecanemab, donanemab, or any other monoclonal antibody for Alzheimer's Disease within the past 6 months OR has a history of treatment complicated by amyloid-related imaging abnormalities (ARIA)
• Currently or within the past 2 weeks taking any of the following classes of medication:
  • Anticholinergic (e.g., tolterodine, benztropine)
  • Sedating antihistamines (e.g., diphenhydramine)
  • any drug that has significant anticholinergic or antihistaminic side effects (e.g., tricyclic antidepressant medications, mirtazapine).
  • Benzodiazepines. While not a strict rule out, this will be decided on a case-by-case basis
  • Opioid. While not a strict rule out, this will be decided on a case-by-case basis
  • Antiepileptic agents. While not a strict rule out, this will be decided on a case-by-case basis
