In general, the criteria for withdrawing patients from the study are based on Axis V of the DSM-IV, Global Assessment of Functioning GAF. No patient with a GAF less than 50 will be enrolled in this study, and any patient whose GAF decreases to less than 50 during the course of the study will be withdrawn. This specifically includes, but is not limited to, any patient reporting suicidal ideation, symptoms of psychosis, or symptoms of mania at any point during the study will be withdrawn from the study and evaluated immediately by Dr. Anderson or Dr. Glod for treatment.
