Cognition in schizophrenia – a systematic review

Reviewing and summarizing the current evidence on cognitive deficits in schizophrenia. A literature search using PubMed was conducted and articles published between 1980 and 2011 containing the words schizophrenia and cognition were reviewed. Patients with schizophrenia show cognitive deficits of one to two standard deviations compared to healthy. The cognitive deficits are associated with functional deficits. No pharmacological intervention is available, but cognitive remediation is promising in improving cognitive deficits and outcome.
