Youth show growing rate of psychosis in Ontario: CMAJ study | CBC News
"People aged 14 to 20 are more often being diagnosed with psychotic disorders, including schizophrenia, compared with those born earlier, a large Ontario study examining 30 years of data suggests. To conduct the study, published in Monday's issue of the Canadian Medical Association Journal (CMAJ), researchers looked at health administrative data from more than 12 million Ontario residents born between 1960 and 2009 to look for cases of a psychotic disorder. Residents had to reach age 14 to be diagnosed and eligible for the analysis."
"Looking at the 30-year study period, researchers found more than 152,000 diagnoses of schizophrenia with the annual rate increasing by 60 per cent for those aged 14 to 20, but staying flat or declining for people aged 21 to 50. Schizophrenia is a lifelong condition where people can experience hallucinations, delusions and breaks from reality that typically require years of treatment. About one per cent of people in Canada are living with schizophrenia, based on federal data from 2016 to 2017."
Health administrative data from more than 12 million Ontario residents born 1960–2009 were analyzed for psychotic disorder diagnoses among those who reached age 14. Over a 30-year period there were more than 152,000 schizophrenia diagnoses, with annual rates rising about 60% for ages 14–20 while remaining flat or declining for ages 21–50. In the 14–20 group the rate went from 62.5 per 100,000 in the 1990s to nearly 100 per 100,000 by study end. Schizophrenia is lifelong and can involve hallucinations, delusions and breaks from reality, often requiring years of treatment. Substance use is suggested as one contributing factor. Early detection and treatment are emphasized.
