Very little data exist on BN in schizophrenia. Gotestam et
al. showed a prevalence of BN with schizophrenia of 0.73%
for men and 1.57% for women [25]. In 1997, Deckelman
et al. described a case of four young women with BN. In
one case, BN clearly preceded the onset of schizophrenia;
in the other 3 cases, the bulimic symptoms interacted significantly
with the psychotic symptoms at the time of the
diagnosis of schizophrenia. These case reports support a
model wherein the coexistence of schizophrenia and bulimia
may have important clinical implications [29]. Miotto et al.
investigated the occurrence of symptoms of psychosis in 112
female patients diagnosed with DSM-IV eating disorders
(AN = 61; BN = 51) and in 631 high school girls in the
same health district as the patients. Compared with controls,
a higher prevalence of symptoms of psychosis has been
observed in patients with EDs; however, no cases of comorbid
schizophrenia were observed [30]. In conclusion, there are
very few studies on BN and schizophrenia, and the hypothesis
of an association between these disorders remains to be
proven..
