Context-processing deficits in schizophrenia: diagnostic specificity, 4-week course, and relationships to clinical symptoms.

چکیده
Previous research on schizophrenia suggests that context-processing disturbances are one of the core cognitive deficits present in schizophia. However, it is not clear whether such deficits are specific to schizophrenia as compared with other psychotic disorders. To address this question, the authors administered a version of the AX Continuous Performance Test designed to assess context processing in a sample of healthy controls, patients with schizophrenia, and patients with other psychotic disorders. Participants were tested at index (when medication naive and experiencing their first contact with psychiatric services) and 4 weeks later, following medication treatment. At index, patients with schizophrenia and the psychotic comparison group demonstrated similar impairments in context processing. However, context-processing deficits improved in the psychotic comparison group at 4 weeks but did not improve in patients with schizophrenia.

Specificity of Prefrontal Dysfunction and Context Processing Deficits to Schizophrenia in a Never Medicated First-Episode Psychotic Sample
Objective: Context processing is a cognitive construct associated with activity in middle frontal gyrus. Schizophrenia-related deficits in context processing tasks have been associated with prefrontal cortical dysfunction. This study evaluated whether context processing-related prefrontal cortical dysfunctions occurred in first-episode, never medicated schizophrenia patients, whether this also ...

متن کاملPersistence, diagnostic specificity and genetic liability for context-processing deficits in schizophrenia.
Context-processing deficits have been shown in schizophrenia during first-episode, medication-naïve status, that persist after short-term antipsychotic treatment and also in first-degree relatives of individuals with schizophrenia. To confirm longer term persistence of deficits, we examined schizophrenia patients (n=63) during first-episode, medication-naïve status through to one-year follow-up...
