A recently proposed definition for remission and recovery in schizophrenia is receiving increased attention by clinicians and researchers. The interest on these issues is based on the recent proposed definition for symptomatic remission, and the development of operational criteria for its assessment, by the Remission in Schizophrenia Working Group (RSWG), in the United States, in 2005. Remission is assessed using eight items of the Positive and Negative Syndrome Scale (PANSS), all of which have to be scored with a symptom severity of <3 points (mild or better), sustained for a minimum duration of six months. In Europe, since 2006, proposed definition criteria about response and remission were introduced. Response can be assessed, with the PANSS, using a cut-off of at least 50% reduction of the baseline score for the acutely ill, and a cut-off of at least of 25% reduction for refractory patients. Remission could be assessed using a formula for calculating percentage PANSS reduction from baseline. Definition criteria have also been introduced to assess functional recovery that includes the combination of clinical and social outcomes for two consecutive years, including dimensions such as psychosocial functioning, cognition, and quality of life. The purpose of this review is to examine existing research on symptomatic remission and functional recovery in schizophrenia. We included clinical and epidemiological studies, reviews and meta-analyses published between January 1970 and July 2013. Sixty two studies on remission and recovery were included, with a total of 94 940 patients, comprising six months to 37 years follow-up. Thirty two studies on functional recovery were included, with a total of 6 483 patients with a range of six months to 42 years follow-up. Research indicates that symptomatic remission can be achieved in 20-97%, and functional recovery in 10-68% of people with schizophrenia. The use of remission and recovery criteria has been recommended for clinical practice and scientific research
