So about 1.5 million people will be diagnosed with schizophrenia this year, worldwide. It is relatively rare for children and older adults to develop schizophrenia, but it does happen. The NCS-R is a nationally representative, face-to-face, household survey conducted between February 2001 and April 2003 with a response rate of 70.9%. The companion review on the incidence of schizophrenia [] found that within the central 80% of incidence rates, the difference ranged from 7.7 to 43 per 100,000 (over a 5-fold difference). When the disease is active, it can be characterized by episodes in which the patient is unable to distinguish between real and unreal experiences. Across studies that use household-based survey samples, clinical diagnostic interviews, and medical records, estimates of the prevalence of schizophrenia and related psychotic disorders in the U.S. range between 0.25% and 0.64%. However, several systematic reviews have elucidated high variability of schizophrenia incidence rates among sites, ranging from 8 to 43 per 100,000 individuals [3, 6]. These individuals may be under-represented in household surveys because they may reside in prisons, other institutions, or may lack a permanent address. The companion review on the incidence of schizophrenia found that within the central 80% of incidence rates, the difference ranged from 7.7 to 43 per 100,000 (over a 5-fold difference).
