[Late catamnesis of recurrent schizophrenia with prolonged remissions (according to an unselective study)].

The author studied the entire population of schizophrenic patients with recurrent forms where the disease proceeded for more than 20 years. Among 115 patients, 97 had long-term (8--40 years) remissions. Two types of development in recurrent schizophrenia with long-term remissions differing in progressiveness are described with rare attacks and with a tendency to series. The data give ground to eliminate the prognostic criteria of the probability of long-term remissions.
