Language-Related Symptoms in Persons with Schizophrenia and How Deaf Persons May Manifest These Symptoms

Disturbances in language have long been viewed as a principal identifying characteristic of schizophrenia. The language-processing deficits of persons with schizophrenia are manifested in a variety of ways. Historically, analyses of schizophrenic patients’ language disorders have focused almost entirely on speech. Deaf persons, however, constitute a portion of the population that is diagnosed as schizophrenic, and sign languages are often their principal means of communication. In recent years, preliminary observations have been reported that indicate that there are a number of similarities between the linguistic deficits of signing Deaf persons with schizophrenia and those evident in the speech of hearing schizophrenic patients. Systematic investigations of schizophrenic Deaf persons’ signing need to be conducted both to improve treatment programs for Deaf patients and to increase our understanding of the language aspects of schizophrenia.
