Inclusion Criteria:

Participants must meet all of the following inclusion criteria in order to participate in the study:

1. Men or women aged 65-90, inclusive.
2. Stable medical condition for three months prior to screening visit, with no clinically significant abnormalities of hepatic, renal, and hematologic function defined as follows: Platelets > 100,000, Serum creatinine ≤ 1.6 mg/dL, aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≤ 1.5 upper limit of normal, No clinically significant abnormalities of other laboratory studies (CBC, chemistry panel)
3. Non-diabetic or well controlled diabetes confirmed by fasting serum glucose <126 mg/dL.
4. Stable medications for 4 weeks prior to screening visit.

5. Physically acceptable for this study as confirmed by medical history, physical exam, neurological exam and clinical tests.

   • Exceptions to these criteria may be considered on a case-by-case basis, at the discretion of the Project Director.

Exclusion Criteria:

1. Female participants that are pregnant or of childbearing potential.
2. Unstable medical conditions for three months prior to screening visit such as poorly controlled blood pressure, diabetes, or breathing problems…etc.

6. History of invasive cancer within the past two years.
7. Contra-indications to lumbar puncture (bleeding disorder, platelet count < 100,000, anticoagulant treatment, major structural abnormality or sepsis in the area of the lumbosacral spine that would make a lumbar puncture technically difficult).
8. Use of any investigational agents within 30 days prior to screening.
9. Contra-indications to MRI (metallic implants, pacemaker, shrapnel, ect…)
10. Sensitivity, intolerance, or allergies to gemfibrozil or any previous reaction to any cholesterol lowering medicine.
11. Major surgery within eight weeks prior to the Baseline Visit.
12. Blindness, deafness, language difficulties or any other disability which may prevent the potential participant from participating or cooperating in the protocol.

13. Physically unacceptable for this study as confirmed by medical history, physical exam, neurological exam and clinical tests.

    • Exceptions to these criteria may be considered on a case-by-case basis, at the discretion of the examining study physician.

Excluded Medications:

1. Experimental drugs
2. Repaglinide
3. "Statins" including but not limited to atorvastatin (Lipitor), fluvastatin (Lescol), lovastatin (Mevacor), pravastatin (Pravachol), rosuvastatin (Crestor), simvastatin (Zocor), or any combination medicines containing these drugs.
4. Coumadin, warfarin, heparin, lovenox, Xarelto, apixaban or other anticoagulants. (Antiplatelet therapy is acceptable).
