Study Arms:
- Intervention Group (Type: EXPERIMENTAL): In the Intervention Group, patients will receive an iPad with the Constant Therapy cognitive rehabilitation application. Patients in the Intervention Group will practice the memory tasks developed for the Constant Therapy application for a total of six months. On a weekly basis, a clinician and/or research assistant will check in with the patient to answer any questions or address any concerns the patient has with using the Constant Therapy application, or how to perform any of the memory tasks. At the end of six months, each individual in the Intervention Group is assessed with standard cognitive testing to determine if there was any change on overall cognition.
- Control Group (Type: ACTIVE_COMPARATOR): The Control Group will not receive any intervention. The Control Group will be given simple sets of puzzle booklets to practice over the 6 month period (e.g., word search puzzles, number and/or math puzzles). The Control Group will also receive standardized cognitive testing at the end of 6 months. Weekly check-ins by a clinician and/or research assistant will also occur in the Control Group. Every 4th patient recruited for the study will be assigned to the Control Group.

Based on this trial design, predict the completion outcome and termination type (if applicable).
