Brief cognitive assessment in schizophrenia: normative data for the Repeatable Battery for the Assessment of Neuropsychological Status*1

Improvement of cognitive functions in chronic schizophrenic patients by recombinant human erythropoietin

“…[44][45][46][47] For analysis, raw data were used throughout the paper. To determine the composite score, they were z-transformed.…”

“…48 Only the MATRICS domain 'social cognition' is not specifically contained in our test set. Among the cognitive tests performed but not included in the test set, mainly due to their lower sensitivity in schizophrenic patients, 14,47 were RBANS subtests visuospatial function, language-picture naming and immediate memory. Secondary end points were timedependent changes in psychopathology scores, motor function (tapping and dotting), blood parameters and MRI volumetrical data.…”

Should cognitive impairment be included in the diagnostic criteria for schizophrenia?

“…However, almost all patients with schizophrenia may demonstrate some measure of cognitive impairment. In comparing patients with schizophrenia and healthy controls on the Repeatable Battery for Assessment of Neuropsychological Status (RBANS) (25), the distribution of a large number of patients with schizophrenia (n=575) is shifted about 2 SDs below the 540 healthy controls from the standardization sample (25,26). Although there is significant overlap between these two distributions, there are very few healthy controls at the lower ends of this distribution and very few schizophrenia patients at the upper ends.…”

“…People with very low levels of education and socioeconomic disadvantage may perform very poorly on cognitive tests independent of a psychiatric diagnosis. Thus, the evaluation of a patient's cognitive impairment must place the cognitive data in the context of his or her background and educational history (26). On the other end of the spectrum, some patients who had demonstrated high levels of cognitive skills early in their lives may have cognitive performance that is in the "normal range" despite significant decline from high premorbid levels (30).…”
