• Patients must have dementia as defined by (1) decline in cognitive function and (2) functional impairment, which together in, in the opinion of the investigator, has resulted in a clinical diagnosis of dementia.
• MoCA < 24 in support of a dementia diagnosis
• Have a reliable and actively involved caregiver who must be able to communicate in English and be willing to comply with protocol requirements.
• If on anti-parkinsonian agents, participants must be on stable dosage for at least 4 weeks prior to baseline.
• If on medications enhancing cognition (rivastigmine, galantamine, donepezil, memantine), participants must be on stable dosage for at least 8 weeks prior to baseline.
• If on antidepressant medications, participants must be on stable dosage for at least 4 weeks prior to baseline.
• If on clozapine, pimavanserin or quetiapine to address drug-induced or disease-related psychosis, participants must be on stable dosage for 4 weeks prior to baseline.
• Female patients of childbearing potential must have negative serum or urine pregnancy tests and must not be lactating. For females able to bear children, a hormonal (i.e., oral, implantable, or injectable) and single-barrier method, or a double-barrier method of birth control must be used throughout the study.
