Some people who experience substance-induced psychosis later develop an enduring psychotic disorder such as schizophrenia. This study examines the proportion of people with substance-induced psychoses who transition to schizophrenia, compares this to other brief and atypical psychoses, and examines moderators of this risk. A search of MEDLINE, PsychINFO, and Embase identified 50 eligible studies, providing 79 estimates of transition to schizophrenia among 40 783 people, including 25 studies providing 43 substance-specific estimates in 34 244 people.

Objective: Dark-skinned immigrants have a higher risk for schizophrenia and other psychoses than other immigrants. The first British studies reported that first-generation immigrants (FGIs) from the Caribbean presented atypical psychoses. This study examines the characteristics of psychotic episodes in black FGIs to Canada.

The original term schizoaffective disorder was invented 75 years ago by Kasanin as a response to diagnostic difficulty with patients who did not fit well in Kraepelin's dichotomy of dementia praecox and affective disorder. However, this was not the perfect solution since criteria for diagnosing schizoaffective disorder were not firmly set at that time. The broad category of schizoaffective disorders included not only patients with co-occurring schizophrenic and affective symptoms but also other "atypical" psychoses.

Childhood-onset schizophrenia (COS; defined as onset by age 12 years) is rare, difficult to diagnose, and represents a severe and chronic phenotype of the adult-onset illness. A study of childhood-onset psychoses has been ongoing at the National Institute of Mental Health (NIMH) since 1990, where children with COS and severe atypical psychoses (provisionally labeled "multidimensionally impaired" or MDI by the NIMH team) are studied prospectively along with all first-degree relatives. COS subjects have robust cortical gray matter (GM) loss during adolescence, which appears to be an exaggeration of the normal cortical GM developmental pattern and eventually mimics the pattern seen in adult-onset cases as the children become young adults.
