This review addresses the question of whether the cognitive deficits seen in schizophrenic patients are the core features of the disorder. In other words, we explore whether schizophrenia is best characterized by symptoms or cognitive deficits (we suggest the latter) and moreover, whether there is a specific cognitive deficit profile that may assist in diagnosis. First, we discuss what the cognitive deficits are. Then we address in turn the reality, frequency, predictive validity, specificity, course and susceptibility to neuroleptic effects of these cognitive impairments. In brief, we argue that various cognitive deficits are enduring features ...Continue Reading
