- Age at time of enrollment: 16 - 65 inclusive (i.e., on or after 16th birthday, up to day before 66th birthday).
- Voluntary informed consent of patient and informant.
- Subject and informant willing to comply with the protocol, \& are available for all scheduled clinic visits.
- Neuropsychiatric Inventory (NPI) Irritability Domain score \> 2.
- Medically and neurologically stable during the month prior to enrollment.
- If taking antidepressant, anxiolytic, hypnotic, or stimulant medications, no change anticipated in these medications during the month prior to enrollment.
- No change in therapies or medications planned during the 28-day participation.
- No surgeries planned during the 28-day participation.
- Vision, hearing, speech, motor function, and comprehension must be sufficient for compliance with all testing procedures. Ability to interact and verbalize sufficient to participate in assessments.
