Mr. C is a 27-year-old Latino father of two daughters who has a history of polysubstance abuse and antisocial behaviors and was brought to the emergency department of a community hospital after asking his girlfriend to call an ambulance. Information was provided by the patient, his girlfriend of five years, and hospital records.Mr. C was in his usual state of health until his initial presentation (as above). His girlfriend reported that over the course of several days, he had become anxious, quicker to anger than usual, and convinced that men in his neighborhood were staring at him and wanted to start trouble. In this initial emergency assessment, he did not meet inpatient level of care and was referred for outpatient services, which he utilized only twice. He had a total of three emergency room visits and two inpatient hospitalizations prior to his index assessment. Outside hospital records are without detailed descriptions, but he is consistently described as having "behavioral dyscontrol," "seizure-like activity," assaultive behavior, and agitation. He consistently denied memory of assaultive behavior, despite being declared persona non grata by one of the facilities. Between inpatient hospitalizations, he attempted to jump from a window in his fifth-floor apartment and was restrained by his girlfriend.He also denied memory of that event, and his girlfriend denied that he expressed an intention to commit suicide then or at any other time. These episodes and his subsequent lack of memory of them were described as "dissociation." Records also indicate that during his second hospitalization he experienced new memories of genital fondling by an uncle. His behaviors and lack of memory of them were attributed to posttraumatic stress disorder (PTSD).Mr. C's inpatient work-up included both electroencephalographic (EEG) and brain magnetic resonance imaging (MRI) studies that were considered unremarkable. He was treated with several psychotropic medications, including antipsychotics (haloperidol, olanzapine, ziprasidone), an anticonvulsant (divalproex), an antidepressant (fluoxetine), three benzodiazepines (clonazepam, diazepam, lorazepam), a hypnotic-antidepressant (trazodone), and a central alpha-2 adrenergic agonist (clonidine). Details such as doses, combinations, and times were not provided in his hospitaldischarge summaries. There were efforts at education, including relaxation techniques to control anxiety. Despite showing little improvement in the episodes of anxiety and dissociation, he gradually became less menacing. At discharge from his second hospitalization, his medication regimen included only clonazepam or lorazepam, clonidine and fluoxetine to treat the PTSD-like symptoms, and trazodone for sleep. Follow-up was arranged with a psychopharmacologist and psychotherapist in a day-treatment program, with recommendation of a cognitive rehabilitation program.Soon after reaching home, he again became very anxious and, within a few days, returned to the emergency department of the community hospital (the point o...
