If female, is postmenopausal/not of reproductive potential defined per protocol~12. Agrees to the study procedures, including undergoing lumbar puncture for cerebrospinal fluid (CSF) samples~Exclusion Criteria:~1. Severe visual, auditory, social, or cognitive impairment~2. Dementia-related disorder other than AD or vascular dementia (eg, Parkinson's disease, Huntington's disease, frontotemporal dementia, schizophrenia, Lewy body dementia)~3. Symptomatic large-vessel disease, symptomatic carotid artery disease, large vessel infarcts, or strategic lacunar infarcts or infarcts\>15 mm~4.
