1. A computer-implemented method for remediating depression in a person, comprising: (a) assessing, using a computer-implemented interactive behavioral assessment regime, a depression index for said person; (b) if said depression index is above a predefined benchmark, periodically reassessing said depression index by waiting for at least a predefined period of time, and performing (a) after said predefined period of time expires; and (c) if said depression index is below said predefined benchmark, treating said person by administering computer-implemented interactive behavioral training to said person, said computer-implemented interactive behavioral training being sufficiently intensive during each training day to create an enduring change in modulatory functions of neurotransmitters of at least one of norepinephrine and serotonin in said person.
