Preoperative Cognitive Reserve in Older Surgical Patients: a Feasibility Study

Feasibility is defined as a 70% completion rate for at least 3 of the six brain exercise games in study participants from which a 'first gameplay score' can be determined. Investigators will also assess level of satisfaction with the brain exercise intervention and barriers to playing in the busy preoperative clinical settings as evaluated by a patient-centered questionnaire (Discharge Survey).
