[Effect of aging on schizophrenia]

The problem of the senescence's influence on schizophrenia and the right to detach this variable from those who take care of temporal evolution is complicated. From a population of 99 schizophrenic patients (DSM III criteria's) having most of 60 year old and most of 20 years schizophrenia's disease evolution; we have study the whole or partial imputability to the senescence of residential statute's modification; frequency, reason, duration of hospitalization's change, psychotic's symptom levelling; and therapeutic's instability.
