4. Potential participant has previously completed 10 or more hours of the computerized cognitive intervention program manufactured by Posit Science.
5. Potential participant is participating in a concurrent clinical trial (involving an investigational pharmaceutical, behavioral treatment, medical device or other) that, in the judgment of the investigator, could affect the outcome of this study.
6. Potential participant is pregnant or breastfeeding.
7. Potential participant has claustrophobia or implantation with any medical devices above the waist that may concentrate radio frequency fields or have other medical issues that may frustrate participation in MRI/PET imaging procedures.
8. Potential participant has a history of large vessel stroke with significant residual motor or cognitive impairment.

14. Potential participant has evidence of a non-neurodegenerative neurological disorder that would interfere with the ability to carry out study activities.
15. Potential participant has has evidence of any other unstable medical conditions that would interfere with the ability to carry out study activities or cause fluctuations in cognition (for example, but not limited to, unstable diabetes, chronic obstructive pulmonary disorder dependent on oxygen).
16. Potential participant has any other clinically significant or unstable medical condition (for example, but not limited to, ongoing alcohol dependency or drug abuse, schizophrenia, psychosis) that in the investigator's opinion would interfere with the ability to carry out study activities.
