[Schizophrenia and eating disorders].
The comorbidity of schizophrenia and eating disorders is understudied. In the early nineteenth century, Eugen Bleuler has reported cases of schizophrenia with eating disorders that were related to delusional ideas. Potomania, merycism and pica have often been described in schizophrenic patients. Schizophrenic patients with eating disorders usually do not meet all criteria for typical eating disorders and are therefore classified as "eating disorders not otherwise specified" (EDNOS). It may even be difficult to recognize schizophrenia in patients with eating disorders associated to delusional ideas and distorted cognitions related to food or body perception. In any case, the diagnosis of schizophrenia should preferably be made and is only valid after renutrition is achieved. The prevalence of schizophrenia in samples of patients with eating disorders is generally below 10% but reaches 35% in males, the most frequent form being hebephrenia. Cognitive behavioural therapies for eating disorders need to be adapted in cases of comorbid schizophrenia. The new antipsychotic medications seem helpful in patients with eating disorders with or without schizophrenia. They reduce anxiety towards eating and bring in better adherence to treatments.
