Schizophrenia affects ~1% of the population and is associated with enormous personal suffering, family distress and burden, and tremendous healthcare and societal costs. Although considerable progress has been made in treating this illness enormous challenges remain.

Early detection and treatment are at present a distant goal. There is undue delay between the onset of full-blown psychosis and appropriate diagnosis and treatment. Continuity of care is often spoken about rather than truly implemented. Adverse effects remain a critical challenge, and comorbid medical conditions as well as suicide result in a markedly diminished life expectancy. Substance abuse affects a substantial proportion of patients, creating an impediment to optimum outcome. Nonadherence remains a very common, but inadequately appreciated obstacle to adequate and sustained treatment response and contributes enormously to a high rate of preventable relapse and rehospitalization.

The focus of this CNS Spectrums supplement is to address many of these topics in a clinically relevant manner by reviewing the latest research findings in pharmacologic and behavioral treatments, with an emphasis on evaluating appropriate treatment for each patient while considering the host of issues that should inform our clinical decision-making. Historically, a major focus of treatment has been positive symptom control. Though this is clearly important, negative symptoms, cognitive dysfunction, depression, demoralization, and comorbid substance abuse are also critical targets in enhancing functional outcome. Concepts such as remission and recovery are useful metrics to help establish targets and goals for treatment planning and for creating a framework for assessing outcome.
