Schizophrenia in old age (late paraphrenia).

Abstract

Late paraphrenia is the form of expression of schizophrenia in old age. Twenty five patients diagnosed as suffering from the condition were studied, and their symptoms compared with the diagnostic criteria for schizophrenia of Spitzer et al (1975), the Catego system (Wing et al, 1974), Carpenter et al (1973a) and Langfeldt (1960). The study confirms late paraphrenia as one of the schizophrenias, and discusses differences with previous studies.
