Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Between March 2008 and September 2009, persons expressing study interest at community presentations or at the Rush Memory Clinic were contacted. Of 524 persons expressing interest, 400 were excluded before consenting for having excluding clinical diagnoses(227), participation refusal (119), and other exclusions medication (54).

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Consented participants underwent a screening evaluation to ensure inclusion criteria were met prior to study treatment assignment and one month run-in treatment with a multivitamin only. Of 124 consented individuals, 20 discontinued prior to randomization due to new medical conditions (9), declining participation (5), and for other reasons (6).
