[Schizophrenia and comorbidity: addictions and violence]

Among the elements of comorbidity found in schizophrenia, it is addiction and violence that figure most among those that preoccupy the entourage of family and cares of patients. These problems can worsen the prognosis of schizophrenia, notably because they further hinder the already complex provision of care and social support, but also because they provoke a cascade of complications and disruptions. On top of these in comorbid manifestations exist fears, preconceived ideas and shady zones. The authors of this article propose a review of the recent literature, on the incidence and nature of these problems, and on the pathways currently being explored as to their origins.
