6. Age 55-90 (inclusive)

7. Stable permitted medications for 4 weeks or longer as specified in Section 6, including:

   • Memantine and cholinesterase inhibitors are allowable if stable for 12 weeks prior to screen

10. Adequate visual and auditory acuity to allow neuropsychological testing
11. Good general health with no additional diseases/disorders expected to interfere with the study
12. Participant is not pregnant, lactating, or of childbearing potential (i.e. women must be two years post-menopausal or surgically sterile)

3. Major depression, bipolar disorder as described in DSM-V within the past 1 year or psychotic features, agitation or behavioral problems within 3 months, which could lead to difficulty complying with the protocol
4. History of schizophrenia (DSM V criteria)
5. History of alcohol or substance abuse or dependence within the past 2 years (DSM V criteria)

8. Clinically significant abnormalities in B12 or TFTs (Thyroid Function Tests) that might interfere with the study. A low B12 is exclusionary, unless the required follow-up labs (homocysteine (HC) and methylmalonic acid (MMA)) indicate that it is not physiologically significant.
9. Clinically significant abnormalities in screening laboratories or ECG.
10. Residence in skilled nursing facility.
