[Functionality as a goal in the treatment of schizophrenia].

Rational use of new atypical antipsychotics have allowed clinicians to have a more optimistic view, on functional outcome in Schizophrenia. Functional outcome is revised here as an essential concept to be kept in mind in the treatment and control of schizophrenic symptoms. This view allows for a better evaluation of the clinical meaning of symptoms and signs, and the impact on daily functioning of unwelcome side effects of some antipsychotics; and finally the impact of all these upon social functioning and may allow the clinician to implement some interventions in the clinical setting taking into account the ultimate and realistic goal in the treatment of schizophrenic patients: their functional outcome.
