  • English-speaking, to ensure compliance with cognitive testing and study visit procedures.
  • Montreal Cognitive Assessment (MoCA) score at screening visit ≥24/30.
  • Female participants must not be pregnant or of childbearing potential (surgically sterile or post-menopausal for \>1 year).
  • Stable medical condition for 3 months prior to screening visit in the opinion of the study physician.
  • Non-diabetic, confirmed by fasting serum glucose \<120 mg/dL and on no oral hypoglycemic agents or insulin treatment.
  • No other clinically significant abnormalities on labs (CBC, chemistry panel, PT/INR, aPTT, urinalysis).
  • Stable medications for 4 weeks prior to screening.
  • Able to ingest oral medications.
  • Physically acceptable for the study as confirmed by medial history, physical exam, neurological exam, and clinical tests in the opinion of the study physician.

You may not qualify if:

  • Significant neurological disease, such as Parkinson's disease, brain tumor, multiple sclerosis, or seizure disorder
  • Major depression in the past 12 months (DSM-IV criteria), major mental illness such as schizophrenia, or recent (in past 12 months) alcohol or substance abuse.
  • History of invasive cancer within the past 2 years (excluding non-melanoma skin cancer).
  • Contraindications to lumbar puncture (bleeding disorder, platelet count \<100,000, anticoagulant treatment, major structural abnormality or sepsis in the area of the lumbosacral spine, or previous lower back surgery that would make LP technically difficult in the opinion of the study physician, hypersensitivity to lidocaine).
  • Contraindications to MRI (pacemaker, shrapnel, metallic implants, etc).
  • Clinically significant abnormalities on labs (CBC, chemistry panel, PT/INR, aPTT, urinalysis).
  • Use of any investigational agents within 30 days prior to screening.
  • Major surgery within eight weeks prior to the Baseline Visit.
  • Severe unstable major medical illnesses, including uncontrolled cardiac conditions or heart failure (New York Heart Association Class III or IV).
  • Antiretroviral therapy for human immunodeficiency virus (HIV).
  • Residence in a skilled nursing facility.
  • Blindness, deafness, language difficulties, or any other disability which may prevent the participant.
