“…It could result from an overall cognitive deficit, difficulty concentrating, distraction, or a preference for expressing simpler ideas. Thomas et al (1987Thomas et al ( , 1990 found greater syntactic simplification in patients with negative symptoms than in those with positive symptoms. The same research group further found that syntactic complexity diminishes as the chronic patient's condition deteriorates , King et al (1990)).…”

Patients with schizophrenia often display unusual language impairments. This is a wide ranging critical review of the literature on language in schizophrenia since the 19th century. We survey schizophrenic language level by level, from phonetics through phonology, morphology, syntax, semantics, and pragmatics.There are at least two kinds of impairment (perhaps not fully distinct): thought disorder, or failure to maintain a discourse plan, and schizophasia, comprising various dysphasia-like impairments such as clanging, neologism, and unintelligible utterances.Thought disorder appears to be primarily a disruption of executive function and pragmatics, perhaps with impairment of the syntax-semantics interface; schizophasia involves disruption at other levels. Phonetics is also often abnormal (manifesting as flat intonation or unusual voice quality), but phonological structure, morphology, and syntax are normal or nearly so (some syntactic impairments have been demonstrated). Access to the lexicon is clearly impaired, manifesting as stilted speech, word approximation, and neologism. Clanging (glossomania) is straightforwardly explainable as distraction by self-monitoring.Recent research has begun to relate schizophrenia, which is partly genetic, to the genetic endowment that makes human language possible.

“…As far as language disturbances in SZ are concerned, it is known that patients with this disease generally have difficulty processing semantic aspects of language (Anand, Wales, Jackson, & Copolov, 1994;Blaney, 1974;Nestor et al, 2001;Paulsen et al, 1996), combining semantic and syntactic information (Condray, Steinhauer, Cohen, van Kammen, & Kasparek, 1999;Condray, Steinhauer, van Kammen, & Kasparek, 2002;Sitnikova, Salisbury, Kuperberg, & Holcomb, 2002;Thomas, King, Fraser, & Kendell, 1990), creating lexico-semantic associations (Salisbury, O'Donnell, McCarley, Nestor, & Shenton, 2000;Salisbury, Shenton, Nestor, & McCarley, 2002;Sitnikova et al, 2002;Titone, Levy, & Holzman, 2000), and accessing and using lexical knowledge (McKenna & Oh, 2005). They also exhibit deficits in verbal fluency, especially in category fluency (Bokat & Goldberg, 2003;Kremen, Seidman, Faraone, & Tsuang, 2003).…”

The study assessed the quantity and quality of errors made by schizophrenia patients in understanding and interpretation of the same metaphors, to evaluate metaphor understanding and explanation depending on the type of presentation material, and to analyze the correlation of illness symptoms with metaphor comprehension and explanation. Two groups of participants were examined: a schizophrenia sample (40 participants) and a control group (39 participants). Metaphor processing was assessed by the subtests of the Polish version of the Right Hemisphere Language Battery (RHLB-PL). The patients were also evaluated with the Positive and Negative Syndrome Scale (PANSS). Schizophrenia patients scored significantly lower in explanation of metaphors, making more incorrect literal and abstract mistakes or providing no answer more frequently. No differences were observed in understanding metaphors; no correlation between symptoms and metaphor processing was obtained. In both groups, picture metaphors were easier to comprehend and written metaphors were easier to comprehend than to explain.

“…Hence, the author came to the conclusion that speech output lacking cohesion may have been caused by different pathophysiologic processes for patients with and without negative symptoms, and that these differences may be decisive for patients to become either treatment responders or nonresponders. As to the time course of language disturbances, Thomas et al [25], in a study of chronic schizophrenia in the community and in long-term wards, found that poor linguistic performance was related to the illness process, and not to institutionalization. Similarly, King et al [26], in their 3-year follow-up of patients, observed a deterioration of language, and particularly syntax, in the schizophrenic process.…”

Using speech samples of 100 patients suffering from schizophrenia, bipolar illness and major depression, we addressed the question of the extent to which the linguistic abnormalities in the speech of these patients represent diagnosis-specific characteristics or constitute independent, syndrome-like dimensions of the illnesses. All speech samples were transcribed by a professional linguist who was blind to both identity and diagnosis of the patients. The majority of the deviant linguistic variables was found to be common to all three diagnostic groups under comparison, while only a few linguistic variables exhibited statistically significant between-group differences. On the other hand, when the respective variables were analysed as a multivariate entity, the variety of subtle between-group differences allowed us to discriminate between the diagnostic groups at an overall performance of 72.7% correctly classified patients. There was an almost complete lack of association between linguistic abnormalities and psychopathology syndromes. In particular, we found no correlation between the syndrome ‘formal thought disorder’ and the large variety of linguistic variables used in this investigation. In consequence, we conjecture that linguistically deviant speech characteristics represent an independent syndrome complex manifested at varying intensities across mental illnesses, and that this syndrome complex deserves greater attention, not only with respect to the principal understanding of the underlying disturbances, but also as a potential target of therapeutical intervention.
