- Mean Brief-A Score [ Time Frame: Baseline ]The BRIEF-A is a standardized measure that captures views of an adult's executive functions or self-regulation in his or her everyday environment. Both a self-report and an informant report are used. The BRIEF-A includes 75 items within nine non-overlapping theoretically and empirically derived clinical scales: Inhibit, Self-Monitor, Plan/Organize, Shift, Initiate, Task Monitor, Emotional Control, Working Memory, and Organization of Materials. All 75 items are rated in terms of frequency on a 3-point scale: 1 (never), 2 (sometimes), 3 (often). Raw scores for each scale are summed and T scores (M = 50, SD = 10) are used to interpret the individual's level of executive functioning. Composite scores are calculated and are scored from a range of 75 (better outcome) to 225.
- Mean Brief-A Score [ Time Frame: 3 weeks ]The BRIEF-A is a standardized measure that captures views of an adult's executive functions or self-regulation in his or her everyday environment.

- Mean PHQ-9 Score [ Time Frame: Baseline ]
The Patient Health Questionnaire (PHQ-9) is a self-administered, nine-item depression scale of the patient health questionnaire. The nine items of the PHQ-9 are based directly on the nine diagnostic criteria for major depressive disorder in the DSM-IV.
The PHQ-9 is the depression module, which scores each of the 9 DSM-IV criteria as "0" (not at all) to "3" (nearly every day). Total scores can range from 0 to 27.
A total score of 0-4 indicates minimal depression severity, 5-9 indicates mild depression severity, 10-14 indicates moderate depression severity, 15-19 indicates moderately severe, 20-27 indicates severe depression severity. Therefore, a high score indicates a worse outcome.
Outcome measures will be assessing a change in scores pre- and post- prescription of Amantadine.
