TL;DR
Neurocognitive function in first-episode psychosis is described by at least five independent dimensions, with significant findings that the MS score was higher for men, and the WM and VL scores were correlated with years of education.
Abstract
BACKGROUND: Assessment of neurocognitive dysfunction in schizophrenia is hampered by the multitude of tests used in the literature. AIMS: We aimed to identify the main dimensions of an assessment battery for patients with first-episode psychosis and to estimate the relationship between dimension scores and gender, age, education, diagnosis and symptoms. METHOD: Eight frequently used neuropsychological tests were used. We tested 219 patients 3 months after start of therapy or at remission, whichever occurred first. RESULTS: We identified five dimensions: working memory (WM); verbal learning (VL); executive function (EF); impulsivity (im); and motor speed (MS). Significant findings were that the MS score was higher for men, and the WM and VL scores were correlated with years of education. CONCLUSIONS: Neurocognitive function in first-episode psychosis is described by at least five independent dimensions.

A large generalized deficit and more subtle differential deficits were observed even in patients with less severe generalized deficit, but the pattern was unlike the amnestic syndrome and probably reflects different mechanisms.

HIV-related NP impairment was generally mild, especially in the medically asymptomatic stage of infection, and most often affected attention, speed of information processing, and learning efficiency; this pattern is consistent with earliest involvement of subcortical or frontostriatal brain systems.

Some implications of classic mental test theory for the solution of the central problem of how to move from statements about differential deficit in performance on specific tests to statements aboutDifferences in ability are presented.

Performance on a secondary task in response to a change in expectation improved dramatically for depressed but not schizophrenic patients, suggesting a more efficient allocation strategy, a greater reserve of processing capacity, or more dependence on motivational factors in depressed patients.

The study's major independent intervention variable is described, i.e. a comprehensive education and detection system to change DUP in first onset psychosis, which appears to be effective and to influence directly the community's help-seeking behaviour.

The finding that the decrement in schizophrenic performance is significantly greater in the distractor condition is significant and may be central to the understanding of the disorder.

Schizophrenic deficits within masking paradigms may involve abnormalities in transient, as opposed to sustained, visual channels, and masking performance deficits were found in manic patients.

The results suggest that deficits on masking procedures are not entirely specific to schizophrenia because comparable masking deficits were found in manic inpatients with chronic disease.

Compared schizophrenia patients to normal comparison subjects in four separate studies are compared and it is recommended that working memory tests be characterized as either transient "online" storage and retrieval tasks or executive-functioning working memory tasks (where storage, manipulation, and retrieval of information is required).

155 Citations1999Keith R. Laws
A pattern of findings challenges notions that schizophrenia is characterised by an executive dysfunction that is: selective; disproportionate to IQ level; and analogous to that found in frontal lobe patients; rather, the poor WCST performance of schizophrenics appears to reflect a generalised intellectual deficit.

Based on the present findings, attentional aspects of executive abilities appear to play a role in learning and working memory and other aspects ofexecution appear to have minimal relationships with memory processes.

The results do not support the hypothesis of a differential deviation in all schizophrenics with respect to distractibility, however, significant differences were found between paranoid and non-paranoid schizophrenics.

Correlations with subject and illness characteristics, symptom dimensions, and work performance demonstrated predictive and divergent validity for the three factors, however, a representative item from each factor yielded similar correlations with very little loss of power suggesting that the factors are composed of highly redundant items.

Increased vulnerability to the masking stimulus was confirmed in schizophrenic subjects, but it is not specific to schizophrenia and is not accounted for by psychotic symptoms alone, since the subjects with ADHD performed similarly.

The documented cognitive deficits in schizophrenic patients probably reflect a more enduring trait-like status with correlations with outcome status, and results indicate that the cognitive measures may be simplified in complexity without a corresponding reduction in their clinical significance.
