Implications for Early Diagnosis and Treatment in Schizophrenia Due to Correlation between Auditory Perceptual Deficits and Cognitive Impairment

It is indicated that auditory perception deficits are present in schizophrenia and related to formal thought disorder. The purpose of the present study was to investigate the association of auditory deficits with cognitive impairment in schizophrenia. An experimental group of 50 schizophrenia patients completed a battery of auditory processing evaluation and a neuropsychological battery of tests. Correlations between neuropsychological battery scores and auditory processing scores were examined. Cognitive impairment was correlated with auditory processing deficits in schizophrenia patients. All neuropsychological test scores were significantly correlated with at least one auditory processing test score. Our findings support the coexistence of auditory processing disorder, severe cognitive impairment, and formal thought disorder in a subgroup of schizophrenia patients. This may have important implications in schizophrenia research, as well as in early diagnosis and nonpharmacological treatment of the disorder.

Male Patients

Cognitive impairment, negative and positive symptoms, primitive release reflexes, and age/temporal disorientation were assessed in 20 male patients meeting the DSM–III–R criteria for chronic schizophrenia and Schooler & Kane's criteria for TD. The control group comprised 20 age-matched male chronic schizophrenic patients without TD. Significant associations were found between TD, cognitive impairment, some negative symptoms, and formal thought disorder. These associations were independent of other illness and treatment variables. The severity of TD correlated significantly with that of cognitive impairment.

Positive And Negative Symptoms

Two studies are reported. In the first, of 62 schizophrenic patients, no correlation between negative symptom scores (rated blindly) and any measure of positive symptoms was found. This independence was confirmed by factor and cluster analyses, which left the question of a third ‘disorganisation’ class of schizophrenic symptoms open. In the second study, of 80 patients, formal thought disorder separated unequivocally into ‘positive formal thought disorder’ and ‘alogia’ syndromes on the basis of correlations with positive and negative symptoms. Catatonic motor disorder also showed evidence of a corresponding positive: negative division, although this only emerged when severity or chronicity of illness was controlled for. Cognitive impairment showed a broad range of affiliations and its particular correlation with negative symptoms was perhaps artefactual.
