• 1.Any significant neurologic disease, such as Parkinson's disease, vascular cognitive impairment/dementia, Huntington's disease, normal pressure hydrocephalus, brain tumor, progressive supranuclear palsy, seizure disorder, subdural hematoma, multiple sclerosis, or history of significant head trauma followed by persistent neurologic defaults or known structural brain abnormalities
• 1.Any significant neurologic disease other than suspected Alzheimer's disease, such as Parkinson's disease (Parkinsonian symptoms complicating MCI/AD are acceptable), vascular cognitive impairment dementia (multiple lacunes less than or equal to 1.5 cm and/or extensive white matter changes are acceptable), Huntington's disease, normal pressure hydrocephalus, brain tumor (clinically insignificant meningioma acceptable), progressive supranuclear palsy, seizure disorder, subdural hematoma, multiple sclerosis, or history of significant head trauma followed by persistent neurologic defaults or known structural brain abnormalities.
• Screening/Baseline MRI brain scan with evidence of infection, or other clinically significant focal lesions. Participants with cortical strokes, not large enough to distort anatomy, multiple lacunar infarctions or extensive white matter disease are allowed.
• Current major depression, bipolar disorder as described in DMS-IV within the past 1 year. Psychotic features, agitation or behavioral problems within the last 3 months which could lead to difficulty complying with the protocol.

• Additional exclusion criteria apply to all diagnostic categories for newly enrolled participants:
• Screening/Baseline MRI brain scan with evidence of large structural abnormalities that would corrupt image analytical pipelines - e.g. large hemispheric infarcts, large areas of encephalomalacia, large arachnoid cysts
• Unable to complete MRIs for any reason (e.g. pacemaker or other implanted metal devices, severe claustrophobia, anxiety which prevents MRI scans, too large to fit, etc.).
• Clinically significant abnormalities in B12, or thyroid function tests that might interfere with the study. A low B12 is exclusionary, unless follow-up labs (homocysteine (HC) and methylmalonic acid (MMA)) indicate that it is not physiologically significant.
