Abstract: A game delivery system delivers a plurality of games in a training program. The training program is configured to systematically drive neurological changes to overcome cognitive deficits associated with a neurological disorder. In one embodiment, the training program includes an initial batch of games that predominantly exercise elemental, lower-level cognitive processes and sensory deficits. After a game participant progresses through the initial batch of games, the training program provides games that impose comparatively greater higher-order cognitive processing requirements on the participant. A clinician portal provides remote access to a clinician to data about the game participant's compliance and performance with the training program. The clinician portal also enables the administrator to configure the training program.
