Exclusion Criteria:

  • be unwilling or unable to perform any of the assessments required by the Protocol.
  • score ≤24 on the Mini Mental State Examination (MMSE).

    • platelets < 100,000/mm3.
    • prothrombin time/international normalized ratio (PT/INR) ˃ 1.5 not due to a reversible cause (i.e. Coumadin).

  • have a sitting or resting systolic blood pressure >180 mm Hg or diastolic blood pressure >110 mm Hg at Screening.
  • have any serious illness or any other condition that, in the opinion of the investigator, may compromise the safety or compliance of the subject or preclude successful completion of the study, or that may compromise the validity of the study.
  • be currently participating in an investigational therapeutic or device trial, or have participated in an investigational therapeutic or device trial within the previous 30 days, or participate in any other clinical trial for the duration of the time that the subject actively participates in this trial.
