Understanding the cognition of patients with schizophrenia could give important insights into the formation of delusional thinking, the fixation of thoughts, and, probably, hallucinatory experiences. In our enthusiasm for an atheoretical descriptive clinical diagnostic schema, the cognitive processes of the patient with schizophrenia have been reduced to the most basic observation: "disorganized speech (e.g., frequent derailment or incoherence)" (DSM-III, DSM-III-R, DSM-IV, and DSM-IV-TR). Consequently, most clinicians and trainees tend to overlook both the complexity and vast literature on cognitive processes in schizophrenia. This concise small book by Philip Harvey and Tonmoy Sharma attempts to rectify this oversight. The 15 chapters cover such topics as learning and memory, working memory, attention, the effects of aging, and executive functions in patients with schizophrenia. These cognitive functions are often more critical than the label of schizophrenia because they determine the disability and potential for rehabilitation of the patient. Also covered are the effects of conventional and atypical antipsychotics, behavioral treatments of cognitive impairments, and other types of psychopharmacological interventions on cognition in patients with schizophrenia.
