Prognosis of the duration of the remissions in attack-like schizophrenia

On the basis of a clinico-epidemiological study of patients with attack-like developing schizophrenia and duration of the disease of 15 years and more the authors report of some results of the prevalence of remissions of different duration. The paper contains data concerning correlations between different duration intra-attack intervals, the type of the sustained attacks, number of sustained attacks and the patient's age at the onset of the disease. The study demonstrated direct correlations between the duration and the type of the attack on the one hand and the character of negative changes--on the other. The formation of protracted remissions is more characteristic of shift-like attacks, i. e. attacks possessing more destructive qualities than in attacks characteristic of recurrent schizophrenia.
