AB  - Psychosis  has  been  defined  as  a  "fundamental  derangement  of  the  mind  characterized  by  defective  or  lost  contact  with  reality."1  The  Diagnostic  and  Statistical  Manual  of  Mental  Disorders,  Fifth  Edition  (DSM-V),2  defines  psychotic  disorders  as  those  that  include  abnormalities  in  one  or  more  of  five  domains:  hallucinations,  delusions,  disorganized  or  abnormal  motor  behavior,  disorganized  thinking,  and  negative  symptoms.  The  hallmark  of  these  psychoses,  schizophrenia,  has  a  worldwide  prevalence  of  0.5%  to  1%3  and  affects  approximately  2.4  million  adults  in  the  United  States.4  Considered  one  of  the  leading  causes  of  chronic  incapacity,  the  term  schizophrenia,  meaning  "split  mind,"  was  coined  by  Eugene  Bleuler  in  1911.5  The  economic  burden  of  schizophrenia  in  the  United  States  in  2002  was  estimated  at  $62.7  billion6  and  typically  accounts  for  1.5%  to  3%  of  the  total  national  healthcare  expenditure,  with  a  high  incidence  of  ED  utilization.7
