Can a precise dose of brain zaps boost memory and mood in seniors?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: i. Age 60-85 (inclusive). ii. English as a first/primary language. iii. Adequate sensorimotor function and verbal expressive abilities to complete all assessments. iv. Must have a Co-Participant (e.g. spouse, adult child or relative, sibling, cohabitator, friend, caregiver) who has at least weekly in-person contact with the participant and is willing to participate in the study as a collateral informant. v. Is on fixed pharmacotherapy (i.e. a stable dose of medication/s) for at least 4 weeks prior to enrollment. Cholinesterase inhibitors, NMDA receptor antagonists, and antidepressants are allowed if on a stable regimen for at least 4 weeks prior to enrollment. Prior treatment with anti-amyloid monoclonal antibody therapy is acceptable if last infusion was at least 8 weeks prior to enrollment. Prior TMS treatment is acceptable if last stimulation session was at least 24 weeks prior to enrollment. vi. A documented diagnosis of MCI per NIA-AA criteria or Mild Neurocognitive Disorder per DSM-5 criteria by a healthcare provider within the past 2 years, with a presumed etiology of either (or both): vi.a Possible or probable AD vi.b Chronic cerebrovascular disease (CVD), specifically small vessel disease as defined in STRIVE-2 which includes small subcortical infarcts, lacunes, white matter hyperintensities, perivascular spaces, cerebral micro bleeds, cortical superficial siderosis, or cortical cerebral microinfarcts. . vii. Met actuarial neuropsychological criteria for MCI within the past 2 years (i.e. ≥2 impaired scores within one cognitive domain, or ≥1 impaired scores in ≥3 domains, where an impaired score is defined as ≤16th percentile using appropriate demographically-corrected norms). viii. Any lifetime depression, as defined by current or past Major Depressive Disorder per DSM-5. Exclusion Criteria: i. A TICS score of ≤ 19 suggestive of dementia. ii. Prior diagnosis of Dementia (NIA-AA) or Major Neurocognitive Disorder (DSM-5). iii. Daily/weekly anticholinergic or sedative use. Stimulants may be allowed pending investigator review. iv. History of significant or unstable condition/s or treatments for these condition/s that may impact cognition (as determined by the study investigators) such as significant cardiac (e.g. heart failure), infectious (e.g. HIV, urinary tract infection), or metabolic disease (e.g. labile diabetes), cancer (e.g. brain cancer, chemotherapy-induced cognitive impairment), developmental disorder (e.g. autism spectrum disorder, intellectual disability), or other neurologic disease (e.g. movement disorder, multiple sclerosis, moderate to severe brain injury, seizures). v. Current treatment for AD/MCI with monoclonal antibody therapy or plan to initiate treatment within three months of enrollment. vi. Current use of any implanted brain stimulation device. vii. Enrolled in a clinical trial or has received an investigational medication or device in the last 30 days. viii. MRI contraindications (e.g., ferromagnetic implants, claustrophobia) ix. TMS contraindications (e.g., ferromagnetic implants, conditions or treatments that lower seizure threshold, taking medications that have short half-lives, no identifiable motor threshold). x. Current alcohol or substance use disorder, bipolar disorder, schizophrenia spectrum or other psychotic disorder, suicidal/homicidal intent within the past month, or any suicide attempts within the past year.
