Outcome Measures

Primary Outcomes (1)

  • The primary outcome of this study will be the evaluation of blood derived neurotrophic factors in both young adults and in mature adults undergoing cognitive training.

    Up to 14 weeks post-enrollment

Secondary Outcomes (1)

  • To obtain information on the levels of growth factors in health adults

    Required blood draws at three study intervals

Study Arms (2)

No Intervention Arm

NO INTERVENTION

Phase I in this study will involve the evaluation of blood-derived neurotrophic factors in healthy, younger adults (18-30.) Individuals in this group will not undergo computerized, cognitive training.

Cognitive Training

EXPERIMENTAL

Phase II of this study will involve an evaluation of the pre- and post- cognitive training levels of blood-derived neurotrophic factors in healthy, mature adults. Participants randomized to this arm will receive SAAGE-based computerized cognitive training.

Behavioral: Computer-based cognitive training

Interventions

The experimental cognitive training program consists of interactive training exercises in which the participant responds to visual patterns and stimuli. The program is designed upon the principles of brain-plasticity, and, for the purposes of this study, is intended to be used for an 8-10 week period (40 total hours of training.)
